CASING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 601,534, dated March 29, 1898. Application filed September 10, 1897. Serial No. 651,238. (No model.)

To all whom at may concern:

Be it known that we, ANTON STRAKA and PAUL H. SCHMIDT, citizens of the United States, residing at Chicago, in the county of 5 Cook and State of Illinois, haveinvented certain new and useful Improvements in Casing- Machiues, of which the following is a specification.

Our invention relates to machines for re- IO moving fatty substances from the surface of sausage-casings, and has for its object certain arrangement of devices for facilitating that operation.

In the accompanying drawings, Figure 1 is I5 a plan with the upper rolls and knives removed, as is also the overhanging frame for supporting them. Fig. 2 is a section on line X X of Fig. 1. Fig. 3 is an enlarged detail in front elevation, showing the supports for 20 the rolls and knives; and Fig. 4 is an enlarged diagram of the rolls and knives. Fig. 5 is a longitudinal vertical section adjacent to the knife-rolls, showing them in position; and Fig. 6 is a similar section with the knife-rolls 25 and suspended boxes removed.

On the frame or bed 1 are supported the drive-pulleys 2, on the endof the shaft for which is a bevel-gear 3, that meshes with another gear 4. On the shaft with the gear4is a worm (not shown) which lies directly under and engages with the worm-gear on the shaft with which is the rubber roll 6. Adjacent to the roll 6 is another roll 7, the two being connected together by the gears 8 and turning in 3 5 the direction shown in Figs. 1 and 2. On the same shaft with the worm-gear 5 and adjacent thereto is a sprocket-wheel 9, from which the chain 10 conveys power to sprocket 11 on shaft 12. Sprockets 13 and 14 and chain 15 convey 0 power from shaft 12 to shaft 16. On shafts 12 and 16 are rubber rolls 17 and 18 and gears 19 and 20. Between the rolls 17 and 18 is a shaft 21, which carries a series of knives 22. Power is communicated to shaft 21 by means 4 5 of pulleys 23 and 24 and belt25.

on the central bridges of the frame 1 are standards 26, which support an overhanging frame 27, the bolts for which are shown at 28 in Figs. 2 and 6. At the front end of the frame 27 is supported a bearing-frame 28, that is vertically adjustable by means of the bolts 29 and is kept from lateral displacement R by the wings 30 on the frame 27.

The frame 281's provided with boxes that support the front ends of rollers 31 and 32, that are similar to and directly over rollers 17 and 18. The central box 33 supports the front end of a knife-shaft 34, that corresponds to shaft 21. The rear ends of these rollers'3l and 32 and knife-shaft 34 might be supported in another frame similar to frame 28,but for convenience they are supported by independent boxes, the adjusting-bolts for which are shown at 35 in Figs. 2 and 5. The rollers 17 and 18 exactly represent the rollers 31 and 32, except that the latter are without sprocket-wheels, as they receive motion from gears that mesh with gears 19 and 20. The knife-shaft 34, which lies directly over shaft 21, is also provided with a pulley 50, similar to 24, to which power is conveyed from pulley 36 by belt 37. The knifesupporting parts of shafts 21 and 34 are octagonal, and the knives 22 are held at an inclination from radial by the clamping-strips, 38 and screws 39.

The position of the casing in the machine is shown by the line Y Y, and the direction of its movement is shown by the arrows Z. The other arrows show the direction in which the rolls and knives move. It will be observed that the rolls all move with the movement of the casing, being, in fact, feeding-rolls, while the knives run against the movement of the casing and act to trim away fatty substances on the exterior. The rolls all move comparatively slowly, while the knives run at high speed. The rolls 6 and 7 are the main feeding-rolls, and roll 6 is adjustable toward roll 7 by means of set-screws 40, the object being to obtain the requisite pressure on the casing that passes between them. The rolls 31 and 32 are also adjustable, by means of screws 29 and 35, toward rolls 17 and 18; but the usual pressure betweenthem is less than between rolls 6 and 7. The gearing to the several rolls is such that the peripheral speed of rolls 6 and 7 is slightly greater than that of rolls 17 and 31 while these in turn exceed that of rolls 18 and 32. The object of this -is to maintain the casing taut, especially at the point where it passes between the knives 22 on shafts 21 and 34.

What we claim is i 1. In a casing-cleaning machine, a frame supporting a knife-bearing roll, an overhanging frame supported on the first-mentioned frame at points adjacent to one end of said knife-bearin g roll, a second knife-bearin g roll carried by said overhanging frame, screws for adjusting the position of said second roll with respect to the first, a pair of main feedingrolls supported on the main frame and adj ustable toward each other, and supplementary feeding-rolls located at either side of said knife-rolls.

2. In a casing-machine the combination with a frame supporting a fixed knife-bearing roll and fixed feeding-rolls at either side thereof and adjacent thereto, of an overhanging frame supported on the main frame at points adjacent to the rear ends of said rolls, complementary rolls supported by said overhanging frame directly above the first-mentioned rolls, screws for adjusting the upper rolls. toward and from the lower rolls, and a pair of main feeding-rolls for drawing casings thro ugh the spaces between the previously mentioned rolls.

3. In combination with a main frame furnishing a fixed support for a knife-roll and feeding-rolls adjacent thereto and at either side thereof, a second frame supported on the main frame at points adjacent to the rear ends of said rolls and overhanging the front ends, a box-bearing frame supported in the over.- hanging frame and guided thereby, screws for adjusting the height of said box-bearing frame, and rolls supported in the boxes of said box-bearing frame.

4. In combination with a main frame having fixed bearings for a knife-roll and a feedroll at each side thereof, a suspended frame having similar bearings directly above the first-mentioned bearings, screws for adjusting the height of the suspended frame, and guides for holding the suspended frame from lateral displacement.

5. A main frame, a pair of main feedingrolls, screws for adjusting said rolls toward each other, fixed bearings on said frame, a knife-bearing roll supported in said bearings, other fixed bearings at each side of said kniferoll, secondary feeding-rolls supported in the last-mentioned bearings, a second frame supported on the main frame at points adjacent to the rear ends of said rolls and overhanging the front ends, suspended bearings carried by the overhanging frame, guides for said bearings, means for adjusting the height of said hearings in said guides, and rolls carried in said suspended bearings.

, 6. A driving-shaft, gears for communicating power from said driving-shaft to a pair of main feeding-rolls,v belt connections from the driving-shaft to a pair of knife-bearing rolls, chain connections from the main feeding-rolls to a pair of supplementary feeding-rolls at one side of said knife-bearing rolls, other chain connections from the supplementary feeding rolls to a second pair of supplementary feeding-rolls located on the opposite side of the knife-bearing rolls, screws for adjusting the several pairs of rolls at and from each other, and an overhanging frame for supporting onehalf of the knife-bearing and supplementary feeding rolls.
