This invention relates toan apparatus for scoring blocks of ice, the general ob'ect of the invention beingto providemeans or lifting .and simultaneously turning each block of ice from edge to side upon a conveyorwhich carries it between upper and lower rows of saws which score opposite sides of the block lat- -erally, after which the block is automatically lowered upon a chute down which it passes by gravity, with vertically 'arranged saws for scoring the block longitudinally as it passes-down the chute, 'the' cuts -made by the latter saws being arrangedat right ,angles to the cuts made by the first saws.` This invention'also consists in certain other features of construction and in Vthe combina- 'tion and arrangement of the several parts,

to be hereinafter fully described, illustrated in the accompanying drawings and specifiure 1.

Figure 5 is an enlarged section online 5 5` Figure 4 is a section online 4--4 of Fig of Figure 4. y

Figure 6 isa view of the front end of the apparatus,

In these views,1 indicates a frame formed mainly of angle iron or the like but having its front uprights 1 formed of heavy channel iron. Each upright 1 is formed with a slot '2 in its lower portionwhich comprises a vertical part and a top part which extends -upwardly andinwardly, as shown. Anelevator frame 3 has trunnions .4 at its ends engaging these slots andv upwardly and inwardly cxy tendingarms 5 are connected with the inner fra-ine and bear against the under part of ashaft 6 which is journaled in the frame adj acent the front end thereof. Ashaft 7 is journaled in supports resting upon the uprights 1 and a crank,disc 8 is fastened to each end of thisshaft 7bars 9`being pivoted at their upper ends to the crank pins'lO and having their lower ends connected with the trunnions so that as theshaft 7 is rotated, the bars will with the part 21.

move upwardly, thus lifting, the,elevatorl frame 3 and as. the said frame moves upwardly, itsarms 5, engaging the shaft 6', will i. A

cause the frame to.. tilt upwardly, and as the -trunnions pass into the sloping ends` of the slots.the ,frame will'assume al vertical position or pract1cally sojand deposit the' block of ice upon its side on theconveyor. The

shaft 6 carries the sprockets 11 and a second.

shaft 12, journaled in the frame, carries the sprockets 13 and theendless chains 14 pass over these sprockets 1l and 13. Each ,of the chains is provided .withpointed projections 15: As will be seen, a block of ice set on edge on theelevator frame 3 will be placed upon its side on the conveyor formedby the endless chains andthe sprockets, as lthe elevator is raised', as 'before described, so that the block of ice will be moved by the conveyor while resting upon one side. The projection 15, en-

gaging the ice, will prevent it from slipping on the chains. Apulley 16 is fastened to one end oftheshaft 6anda speed reducer 17, sup'- ported upon the toppof the frame, has a pulley upon its shaft overwhich passes abelt 18, said belt also passing over apulley 16 so thatthe conveyor is actuated from the speed reducer.

This speed reducer is connected to a pulley 19 loosely mounted onshaft 7 through means ofbelt 20. This pulley 19 is provided with a clutch part 2l and aco-operating part 22 is slidably., but non-rotatably'connec'ted with theshaft 7. Aworin 23 forms part of theclutch 22 and acoil spring 24 on 'the shaft 7 v tends to force theworm and thepart 22 forwardly to place said part 22'l in engagement Abell crank lever 25 is pivoted 'to a part of the frame and'has a hook 26 on its upper arm which normally engages the worin and holds the parts with the spring contracted and theclutch part 22 out of engagement with the clutch part 21. Aspring 27 holds the bell crank in this position. The lower end of the bell crank is formed with arightangular exf tension 28 which is inthe path of ablocl; of ice being slid on theelevator part 3 so that when the block strikes this projection, the bell crank will be tilted so that its hook 26 will move out of Contact with the worin and thus thespring 24 can push theclutch part 22 in engagement with the clutch part 21. This will cause theshaft 7 vto be turned by the actuating means and thus the elevator will be raised by the crank means. before described. As soon as the bell crank is released from the pressure of ,theiblock of ice, it will returnv to its normal position with the hook engaging thel outer part of the worm so that as the worm revolves, the hook will pass through the grooves thereof, thus gradually drawing the worm and the clutch away fromthe clutch part 21 andthus stopping further rotation of theshaft 7. These parts are so formed that the"elevator will be raised to place the block of ice upon the `conveyor andv thenreturn to its normal position duringl one revolution of clutch 21.

'Ashaft 29 isy journaled in the frame midway between the shafts' and 12 and this haft carries a plurality ofsaws 30. A second Zhaft 31 is journaled in the top ofthe frame directly above theshaft 29 and thisshaft 31 carries a plurality ofsaws 32. These saws are adjustablyA arranged on their shaftsl so thatthey can be moved toward or away from each other 'and as will be seen, the block of ice traveling along with the `conveyor Will -pass between the upper and lower sets of saws so that-the upper and lower faces of the block will .be scored byY these means.

-A motor M is supported upon the top of the frame. and abelt 33 passes overa pulley on the motor shaft and overpulleys 34A andf 35 on theshafts 29 and 31 so that the saw shafts are rotated from the motor.

shaft 31 is belted to the shaft of the'sp'eed reducer 17, as shown at 36, so that the conveyor and the elevator are actuated from the motor.

A frame37 is naled in the rear part ofthe main frameI so that the frame 37 is tiltably supported and a cable'39, fastened to an arm on the shaft,

' passes upwardly to an L-shaped member 40 which is connected to apiston 41 arranged incylinder 42 on the top of the main frame.

Acoil spring 43 in the cylinder normally holds the piston at the -top of the cylinder so :that the cablei39 'normally holds vthe frame 37 in horizontal position so that this frame 37 will receive the block of ice passing .from the' conveyo'r. As-the weight of the block comes upon the frame 37, it will tilt downwardly, thus turning the block upon lits edge and at the end of the'downward movement, the frame will deposit the block upon an inclined chute 44 whichextends .transversely of-the main frameat the rearl end thereof. The block, resting on its edge will slide down the chute and it will pass between the twofsets of saws 45 which are adjustably fastened to the shaft 46, one of which is driven by the motor M and the other of' which vis belted to the motor driven shaft,

as shown at 47. Illhese shafts are arranged at an angle to the vertical so that the saws 45 are The fastened to ashaft 38 jour- ,provided that such changes scope of the appended claims. l

arranged in planes which areparallel to the chute 44 so that these saws will make parallel longitudinal cuts in the sides of the block as y v it passes between them, these cuts being at right angles to the cuts made by the other saws. Thus the large block can be easily divided into smaller blocks. As soon as the block passes from the frame 37, the'spring and the parts associated therewith will return said f rame to its normal position.

From the foregoing it will be seen that I have provided means for lifting and simultaneously turning a block of ice from edge to side upon a. conveyor, cutters or saws for f laterally scoringthe upperand lower faces conveyor, means for again turning the 'block on Iits edge as it'leaves the conveyor and depositing it on a chute and means for scoring theJ faces of the block longitudinally as it passes down the chute, it simply being necessary to slide the block on edge on the elevator with suflicient energy that its contact with the bellcrank extensionl part 28 will allow the clutch parts to engage after which no atten,- tion is required from the attendant until the block leaves the apparatus.

The bearings. for theshaft 29 can be adjusted vertically by thescrew 48 so that the lower 'saws can be raised to make deeper lateral cuts on one side ofthe block and if desired, two large saws may beused with the of the block as it travels along with the' v'othersaws 30,and 32 so that rough edge uniform.
