HOG-CONVEYER.

SPECIFICATION forming part of Letters Patent o. 621,116, dated March 14, 1899.

Application filed September 4, 1897. Serial No. 650,693. (No model.)

To all whom it may concern,.-

Be it known that I, NATHAN MANDEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hog-Conveyers, of which the following is a specification, reference being had to the accompanying drawings.

Heretofore it has been the practice in slaughter-houses where hogs are slaughtered to attach a shackle to one of the hind legs of each hog and to suspend the hogs from an inclined rail by means of trolleys or hooks attached to the shackles. The inclined rail extends from the shackling-pen to the scalding-tanks, and as the'suspended hogs move along in procession they are stuck by the sticker as they pass before him and in due time thereafter are dumped into the scaldingtank. This method of handling hogs is objectionable for several reasons. In thefirst place a number of hands are required in the shackling-pens of the houses where largen umbers of hogs are slaughtered daily, and atv several other stages of the operation other hands are required,-as in dumping the hogs into the scaldin g-tank, removing the shackles, In the second place where ay shackle is attached to one of the hind legs of a hog and it Vis elevated to the rail by means of the shackle-chain it frequently happens that the hog is jerked violently, bruising the hams or otherwise injuring the animal.

The object of lmy present invention is to avoid the objections above pointed out and to provide an improved apparatus for handling hogs in slaughter-houses so that they may be driven directly from the pens in which they are confined to the slaughter-pens and be delivered therefrom automatically to the sticker, and then be automatically dumped into the scalding-tank, by thisv means not only dispensing with a large number of the hands heretofore necessary, but avoiding the danger of injuring the animals.

To this end my invention consists in providing a suitable carrier with means for receiving the hogs and holding them in a vertical position head downward in such manner l as to expose the throat to the sticker, the carrier being arranged to convey the hogs past the sticker to the scalding-tank.

My invention further consists in providing means'for automatically discharging the hogs into the scalding-tank and in certain other improvements, which will be pointed out in detail hereinafter.

In the accompanying drawings, Figure 1 is a plan view of one form of apparatus. Fig. 2 is a longitudinal section on line 2 2 of Fig. 1. Fig. 3 is a plan view of another form of apparatus designed for slaughter-houses of smaller capacity. Fig. 4 is a longitudinal section on line 4 4 of Fig. 3. Fig. 5 is an enlarged detail, being a side elevation of one of the flasks. Fig. 6 is a vertical section thereof, and Fig. 7 isa plan view.

In the drawings, 8 indicates a carrier which, as shown in Fig. 2, is Ain the form of a turn; table and is supported uponballs 9, running in a track 10, supported upon posts 11, so that the carrier 8 turns readily. Arotary motion is given to the carrier by means of a vertical shaft l2, driven by a pulley 13 or other suitable mechanism, the shaft being preferably arranged below the carrier 8 and being keyed to the hub thereof, as shown.

14 indicates a series of flasks arranged around the periphery of the turn-table 8, said fiasks being arranged to receive a hog and hold it in a vertical position head downward, as shown in Fig. 6. To this end the lower portion of the flask is contracted, as shown at 15 in Fig. 6, the inside of the flask being tapered, so that the hog lis prevented from turning around. The flask 14 is formed in two semicylindrical parts connected at one side by hinges 1G and at the other side by a latch 17, which engages a pin 18, the latch 17 being hinged to one of the members and the pin 18 projecting from the other member in a suitable position to be engaged by the latch 17 for the purpose of holding the members to gether to hold the flask in closed position. The latch 17 is provided with .a downwardlyprojecting arm 19, the lower end of which is preferably beveled or bent at right angles, as shown at 2O in Fig. 5. A spring 21, which is secured to one of the members of the flask at one side of the hinges 1G and projects around said hinges and bears against the other member of the flask, as shown in Figs. 5 and 7, serves to close the flask after it has been opened.

22 indicates a door with `which each flask is provided, said door being arranged in the outer lower portion of the flask and being normally closed by a spring 23. The door 22 is to permit the sticker to gain access to the throat of the hog if he is unable to reach it with the door closed.

24 indicates an elevated chute which leads A to and terminates over the flasks 14. As shown in Fig. 2, the floor of the chute 24 at the end near the carrier Sis formed by aconveyer consisting in the apparatus here shown of a bolt 25, running over pulleys 26. A deflector 27 is provided at the inner end of the chute 24. Said chute is of such Width that the hogs will be requiredV to move along it in single file, and the conveyer-belt 25 moves at a rate of speed proportionate to that of the carrier, so that a hog will be delivered to each flask as it moves below the end of the chute, the defleetor 27 serving to properly direct the hogs into the flasks as theyare carried along by the conveyer.

2S indicates a scalding-tank, one end of which projects under the flasks 14, as shown in Figs. 1 and 2. l

29 indicates a cam suitably secured upon a bar 30 (or in some other suitable way) at a point about midway of the width of the scalding-tank, as shown in Fig. 1. The cam 29 is adapted to be struck by the lower end of the arm 19 of the latch 17 and to lift said arm, raising the latch and permitting the weight of the hog to spring apart the members of the flask, the hog being thereby discharged into the scalding-tank. As soon as the hog is discharged the spring 21 will close the flask, the latch automatically rengaging the pin 18 and locking the flask in its closed position.

The operation of my improved apparatus is as follows: The hogs are driven into the chute 24, and when they reach the conveyer therein are carried along in single file and are discharged head l'irst into the flasks 14. It is obvious that as the hogs fall into the flasks they will lie with the throat outermost in proper position for the sticker, who stands at the side of the chute 24 opposite to the scalding-tank. As the hogs are carried before him the sticker sticks them, after which they are carried around by the carrier until they reach the scalding-tank, when the latch 17 will be tripped by the cam 29 and the hog discharged into the scalding-tank, his weight opening the flask as soon as it is unlocked. As soon as the hog is discharged the spring 2i closes the flask and the latch 17 automatically locks it, so that it is then in proper order to receive another hog as it passes again under the chute 24.

'shown in Fig. 3.

The form of apparatus above described is particularly adapted for slaughter-houses where large numbers of hogs are slaughtered and'where plenty of space may be secured. In smaller houses, however, where the quarters are cramped, instead of using a turn-table carrier, as shown in Fig. 1, I prefer to use the form of apparatus shown in Figs. 3 and 4, wherein the flasks are carried by an endless belt 31, which is caused to move in a horizontal plane by sprocket-wheels 32 33, as

as 32, is driven by a shaft 34, as shown in Fig. 4. In this form of apparatus the flasks are supported partly by the belt 31, but principally by trolleys 35, which move around a track 36. Instead of using asheet-metal wall for a track, as shown in Fig. 4, an ordinary track may be used, supported in any suitable manner. In other respects the apparatus shown in Figs. 3 and 4 is similar to that shown in Figs. 1 and 2, and its operation is substantially the same.

It will be seen from the above description that in my improved apparatus the hogs require practically no handling whatever, as all 'that it is necessary to do is to drive them into the chute 24, whence they are automatically carried past the sticker and discharged One of the sprocket-wheels,l

into the scalding-tank. No shackles are used,

and as the fall of the'hogs from the chute is not great there is no danger of injuring the animals.

I have described my improved apparatus in detail in order that it might be fully nnderstood; but I do not limit myself to the specific details of the apparatus described, as many modifications maybe made without departing from my invention, which consists, broadly, in combining with a carrier a plurality of flasks or other devices adapted to receive and carry the hogs past the sticker to the scalding-tank, also in combining with such apparatus means for automatically discharging the hogs into the scalding-tank, and in the more specific features hereinafter claimed. My invention therefore includes all equivalent devices.

That which I claim as myinvention, and desire to secure by Letters Patent, is-' 1. The combination of a carrier, one or more animal-receptacles carried thereby, said receptacle being open at the top to receive the animal and having a smaller opening at the bottom whereby the animal is supported in the receptacle with its throat exposed, and means whereby the animal may be discharged from the receptacle, substantially as described.

2. The combination of a carrier, one or more animal-holding flasks carried thereby, said liask or'flasks being arranged to hold the animal in a substantially vertical position head downward, and having a contracted opening at the bottom whereby the animal is supported in the receptacle with its throat exposed, said flasks being composed of separable members,

and means for normally locking said members together to retain the animal in the flask, substantially as described.

3. The combination with a carrier and animal-holding receptacles carried thereby, a chute extending over said receptacles and adapted to discharge thereinto, and means for positively feeding the animals into said receptacles, substantially as described.

4. The combination with a carrier andone or more animal-holding-flasks carried thereby, said flasks being larger at the top than at the bottom and being composed of separable members, and means for locking the members of said flasks together, substantially as described.

5. The combination of a carrier and one or more animal-holding flasks carried thereby, said flask or flasks being arranged to carry the animal in a substantially Vertical position head downward, and means for feeding the animals, head first into said flasks, substantially as described.

6. In an animal-conveyer, the combination with a rotary carrier and one or more animalreceptacles carried thereby for receiving and `supporting animals, said receptacles being largerat the top than at the bottom,and means for discharging the animals from said receptacles, substantially as described.

7. A hog-holding flask 'consisting of two members hinged together, said iiask being arranged to hold the hog in a vertical position he'ad downward, and means for locking the free edges of the flask together, substantially as described.

8. A hog-holding flask consisting of two members hinged together, said flask being arranged to hold the hog in a Vertical position
