7 Claims. (01. 312-72) This invention relates to apparatus for storing and dispensing articles such as bobbins.

It has been found that in factories in which a great number of sewing machines are used, and in which the operators of such machines have free access to a supply of bobbins, there isoccasioned an appreciable loss due 'to Ithe'fact that many of the bobbins, which are usually wound with thread at all times, are carried oft-or misplaced by the operators, or are otherwise lost. In addition to the direct monetary loss, "the inconvenience and delay caused by the loss of bobbins are highly objectionable. Heretofore, this situation has been tolerated because of the fact that the operators, in many instances, must have ready access to a great number of bobbins, so that they may, as required, change the color or character of the thread used in their machines; and because of the expense and inconvenience involved in the maintenance and use of an attended stockroom.

The general object of the present invention is to provide a dispensing apparatus which, while making bobbins or the like readily available, will prevent their misplacement "or loss, thusserving, in effect, as an automatic stockroom.

It is another object of the invention to provide a dispensing apparatus from which a bobbin can be removed only by insertionof another substantially similar bobbin; which may be operated in a very simple and eflicient manner; and which, in construction, is relatively simpleand inexpensive,

Other objects, features and advantages of the invention will more fully appear from the following description, to be readin connection with the accompanying drawings-of a preferred embodiment of the invention, in which drawings,

Fig. 1 is an elevational View of one side of the apparatus, partly broken away to show apart of the inner rotating member;

Fig. 2 is a view in plan of the apparatus of Fig. 1;

Fig. 3 is a sectional view taken' on theline 33 of Fig. 1; and

Fig. 4 is a fragmentary elevational view of the other side of the apparatus.

Referring to the drawings, the numeral ll! des-' ignates generally a casing which, in the'preferrecl form of the apparatus illustrated, comprises side wall ll, side wall [2 and a centerpiece l3, disposed between the side walls H and f2 and suitably 'SBCUI'Bd'thBIBtO in any desired manner, as by screws or the like I'Oa. Within casing I0 "is disposed a rotating member .14, carriedupona shaft 15 journalled at l6, it in side walls H and I2. Shaft I5 may be forced-fitted within the central opening I! of member [4 or otherwise secured to the member [4, as by being keyed thereto, as at Ma, so that the member is rotatable therewith. To facilitate rotation of shaft l5, and hence of member I4, the shaft is preferably provided with wheels [8, I8,

Member 14 is circular, and its axial thickness is slightly greater than the diameter of theb'obbins which are to be dispensed. Centerpiece i3 is slightly greater in'thick'ness than member I4, to provide the clearance between the .side walls H and I2 and the member l4 necessary for unimpeded rotation of the latter.

Member [4 is provided with a plurality of peripherally arranged spaced recesses! 9. Each recess l9'is slightly larger than, and is adapted to contain, abobbin 29, preferably in the manner indicated in the drawings, 1. e., with the axis of the bobbin at a right angle to the axis of shaft IS. The bottom of each recess is preferably formed in the manner of a trough, as indicated at Mid, so that the bobbins will tend to be centered within their respective recesses and thus kept from contacting the inner surfaces of side walls II and I2. 1'

Centerpiece l3, which is arranged substantially in coplanar relationshipwith'inember I4, is recessed to accommodate the latter, the edge 2| ofcenterpiece 13 being arcuate and following the contour of the periphery ofmember 14 throughout at--least the lower half of said member. As indicated in the drawings, it is preferred that the edge 2| follow-the contour of the periphery of member M .to'p'oints above the axis of rota tion of such member: The edge 2| is spaced slightly from the periphery of member [4 to provide the clearance necessary for unimpeded rotation of the latter. It will be seen thatedge 21 of centerpiece l3 serves toprevent' bobbins from-fallingdownwardly out of their respective recesses.

Side walls II and I2 have upwardly extending arcuate edge portions lid and l2a,which follow the contour of member'ld. These edge'portions support a transparent pl'ate'22 of glass, celluloid or the like, secured "thereto in'any desired manner, as byscrews 23. Thus,'as themember 14 is rotated, one can see, in succession, .all of the bobbins which are retained in the recesses thereof. For purposes hereinabove indicated, there is a slight clearanceybetween thetransparent plate 22 and the periphery :of member l4.

sidewall ll isxprovicled with an opening.

Communicating with opening 24, and secured to side wall II as by brackets a, is achute 25, through which bobbins which are to be supplied to member I4 are delivered to such opening. The chute is large enough to permit the free fall of bobbins therethrough, but is sufficiently limited in size so that the bobbins are not permitted to turn or fall over as they pass through the chute in vertical position.Opening 24, similarly, is of such proportions and dimensions that the bobbins passing therethrough are not permitted to turn or fall over.

Chute 25 is provided, proximate its lower end, with a.reciprocable plunger 23, arranged in alignment with opening 24 and adapted to reciprocate at a right angle thereto. Plunger 25 has an enlargedend portion 21 which may be grasped to facilitate operation of the plunger and which, by abuttingshoulder 28 ofchute 25, limits the travel of the plunger. The eifective length ofplunger 25 is such that when the enlargedend portion 21abuts shoulder 23, theoperative end 26a of the plunger will be approxi mately at the inner end of opening 24 and prevented from traveling therebeyond in the direction of member I4.Plunger 26 should not be substantially longer, as it would then be possible to dislodge, at least partially, a bobbin from its recess in member I4 without first having supplied another bobbin to the apparatus. Theoperative end 26a of the plunger is preferably enlarged, so

' as to engage the flange portions of the bobbins actuated thereby, and to prevent total withdrawal of the plunger from thechute 25.

To supply a bobbin to the apparatus, one drops the bobbin, in vertical position, intochute 25, while the plunger is withdrawn as far as possible, and then presses the plunger. The operative end of the plunger is thus caused to .bear against the bobbin and force it through opening 24 into a recess which, by suitable rotation of member I4, has been arranged in registry with opening 24. It is in this way that the various recesses I9 of the apparatus, or any ofthem, are charged, that is, initially supplied with bobbins.

' Side wall I2 is provided with discharge opening 29 in juxtaposition with opening 24.Opening 29 is of substantially the same size and shape as opening 24. Preferably, however, the bottom. of opening 29, designated 29a, slopes downwardly toward the outer surface of side wall I2, as best seen in Fig. 3.

The opening 29 is covered'by aprotective casing 30 which is of sufiicient size to receive a bobbin therewithin. Thebottom 3| of casing 39 is arranged at or :below the lowermost end of thebottom 29a of opening 29, so that a bobbin passing through opening 29 falls downwardlyintorthe casing 30. The casing 39 is closed exceptfora discharge outlet 32 formed in one of the walls of said casing, said outlet being at a lower level than opening 29 and preferably being at a right angle thereto.Outlet 32 is of sufficient size to permit the free passage of a bobbin therethrough. The

bottom 3| ofcasing 30 is slopingly arranged and constitutes, in effect at least, an extension of a downwardly slopingdelivery trough 33 into which bobbins may be discharged throughoutlet 32. Thus any bobbin which passes through opening 29 will fall freely through casing 39 andoutlet 32 to the lower end oftrough 33.

To prevent lateral displacement of bobbins from the recesses I 9 of member I4, except by the application of substantial force, there are provided resilient means, such assprings 34 and 35, inopenings 24 and 29 respectively.Spring 34 is preferably attached, in any desired manner, to one of the inner surfaces ofchute 25, andspring 35 is preferably attached to the inner surface of the top wall of casing 39.

The apparatus may be secured in position in any desired manner, as by the use of brackets, for example. In the preferred embodiment of the invention which is illunstrated,base members 36, 36 are provided to insure the stability of the apparatus in its normal, upright position.

In operation, the apparatus is first charged with bobbins in the manner indicated above. Thereafter, wheneverit is desired to obtain a bobbin from the apparatus, this can be done only by supplying another bobbin to the apparatus. Thus, the operator of a sewing machine, if she wishes to change bobbins, removes from hermachine a bobbin for which she has no further immediate use and, after withdrawingplunger 25, inserts such bobbin inchute 25. Then, or before the insertion of a bobbin inchute 25, she rotates member I 4 by means of one or both of wheels I8, until, as determined by looking throughtransparent'plate 22, the bobbin which she desires is arranged opposite theplunger 26. The plunger is then pressed in, causing the bobbin inserted inchute 25 to displace the desired bobbin from its recess I9, and to be substituted therefor in such recess. The desired bobbin, forced throughopening 29, falls to the bottom of casing 39 and is delivered throughoutlet 32 thereof to the'lower end ofinclinedtrough 33, from which it may be removed by the operator.

Each sewing machine includes means for rewinding thread upon a bobbin, and it is common practice to wind thread upon an empty, or partly empty, bobbin during the time in which another bobbin in the machine is used for sewing. The bobbin which the operator inserts in the apparatus hereinabove described is, in each case, one upon which thread has been thus wound, so that the apparatus continues to be charged with fully wound'bobbins.

It will be observed that while the bobbins contained in the apparatus are readily available and may easily be examined, they. are protected against excessive handling and consequent soiling of the thread wound thereon. The casing I9 is, moreover, in the preferred embodimentof the invention hereinabove described, substantially dust-proof, and the thread wound on the bobbins contained therein is thus kept clean and fresh. While asolid plate 22 of transparent material is preferred, it is to be understood that the invention contemplates the use'of any material permitting vision therethrough, such as a screen or the like, although in such event, dust and other foreign matter may freely enter the casing and soil the thread wound on bobbins therein.

a It is to be noted also that thedispositionof casing 30 and theoutlet 32 therein, at the discharge side of the apparatus, and the disposition ofchute 25 at the inlet-side of the apparatus,

render it impossible, for all practical purposes, to obtain a bobbin from the apparatus except in the manner hereinalbove explained. The fact that the length and travel ofplunger 26 are limited, and the provision ofsprings 34 and 35, also contribute to the attainment of this result. If thechute 25 orprotective casing 30 were not provided, it might .be a simple matter to remove a bobbin from the apparatus by means of tweezers or the like, or to force a bobbin from the apparatus by the insertion of a finger or an object such as a pencil. Ifsprings 34 and 35 were not provided, the bobbins might be rolled out of their respective recesses l9, throughopenings 24 and 29, by tilting or striking the apparatus. Ifplunger 26 were not limited as to its length and travel, it might be used to force a bobbin from its recess without the insertion in the apparatus of a replacement IbOb-bill. And the fact thatoutlet 32 ofcasing 30 is at a lower level than discharge opening 29, and is at a right angle thereto, makes it particularly difiicult to remove a bobbin through such outlet otherwise than by operation of the apparatus in the intended manner.

Since many changes may be made in the invention without departing from the scope thereof, it is intended that the foregoing description and accompanying drawings be regarded as illustrative only and not in a limiting sense.
