Application 'tiled September 19, 1922. Serial No. 589,277.

To all whom timely concern:

Be it known that l, ALFRED lVoo'LnN, a citizen of the United States. residing at Oklnulgee, in the county of Okmulgee and State of (,)klahomaghave invented certain new and useful Improvements in Pistonlting Squeezers, of which the following is a specification.

i My invention relates to a tool for use in applying piston rings to the pistons of an yinternal combustion engine and is of the type that is known as a ring squeezer meaning thereby that the rings are placed in position by squeezing them so that they may fit into the cylinder. A

One of the objects of the invention is to provide a device of this character which will enable the operator to use both hands in inserting the piston'in the cylinder.

A' further object is to provide a device with removable handles so that the operator can take same down to replace any broken parts or for replacement in tool box.

Another object is to provide a construction so that the handles 4can be set at various angles to facilitate inserting lthe piston in the cylinder.

With these Vgeneral objects` in view, my invention consists in certain novel and pe- 3@ culiar eatures'of construction and combination of parts as hereinafter described and claimed, and in order that it may be fully understood, reference is to be .had to the accompanying drawing, in which:

Fig. 1 1s a perspective view ot the ring squeezer. showing handles;

F ig. 2 is a sectional elevation showing the method of using when inserting the piston from the bottom ot the cylinder;

Fig. 3 is a plan view showing the rangel ot adjustment of the band tor varying sizes or1 pistons;

Fig. a is a section on the line a-l oit Fig. 3;

Fig. 5 is a section on the line 5--5 of Fig. 3;

Fig.v tl is. a section on theline 6 6 of Fig. 5.

lin the drawings, 1 is an outside band and 2 is an inside hand, both being formed of thin springv sheet metal each provided at its inner end with oilset ears t and 5 respectively, reinforced bymetal strips 6 and t' `and pivotally connected to theends 8 and tl ot crossedhandles 10 and 12 pivoted together at 13 and to the said odset ends and ears.

For holding the handles in adjusted position relative to the said hands, l provide set screws la and 15 secured to said bands to and having thumb ,nuts 16 and 17 for clamping together the handles and band. Pivoted to one of thehandles 12 is a ratchet bar 18 when''set upholds the two bands in adjusted position. Theinner band 2 is Aalso provided with a slot 2t, the enlongatedrectangular tongue 25 of thescrew 27 slidably engaging S0 therewith and the said tongue on the inner side of the saidband 2 having secured thereto a sheet ofmetal 26 to prevent the said slot from catching on a ring. Thescrew 27 passes through a closelyfitting aperture 28 85 in the band 1 and is provided with athumb nut 29, tor securing the two bands in adjusted relation.

The inner end oit each band is tapered as at 30 and 31 so as not to interfere in any t@ way with the placing ot the ring in position. All the screws are made .with square shoulders and riveted to the bands so that there will be no danger in turn-ing in hing the necessary adjustments.y it@ Operation When it is desired to place a ring in position, the band is rst set to a size correspondin with the size of the piston. The te@ piston rung is then squeezed uptight around the piston and held in this position by the ratchet locking the tool in set position. The piston may then be inserted in the cylinder with both hands ot the operator, the handles te@ being adjusted to the suitable angle to facilitatey operation.

0n both ends ot some cylinders and on the lower end et all ot them, a charniter or concave 32 is provided in which the thin mi@ band of metal is adapted to tit as shown in Fig. 2.

From the above description it will be apparent that I have produced a device of the character enumerated as desirable and While I have illustrated and described the preferred form of the invention, it Will be understood that I reserve the right to all changes properly falling Within the spirit and scope of the appended claim. Having described my invention, what I claim as new and desire to secure by Letters Patent is:

A ring squeezer comprising a two part circular band of thin springy sheet metal adapted to surround the piston and having a free and unobstructed edge adapted to fit into the chalnfer of the cylinder of an engine, means for adjusting the said parts of the band relative to eachother to vary the diameter of the band, each part being provided at one end with an oifset ear located Within the plane of the band, a pair of crossed handles pivoted together,y means for locking the handles together to hold the band in set position, each handle pivoted to one of the said ears to permit angular adjustment oi' the said handles relative to the plane of the band.

In testimony whereof I atlix my signature.
