MEAT CUTTER.

Specification of Letters Patent. p t t d A 29 1922 Application filed February 4, 1920. Serial No. 356,324.

To all whom it may concern:

.Be it known that I, FRED G. WALKER, 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 Meat Gutters, of which the following is a specification.

This invention relates to a machine for cutting meat or other analogous substances and is concerned chiefly with certain improvements in that type of machine which utilizes a saw or cutter in the form of a band that travels around upper and lower wheels suitably mounted in a framework.

An exemplification of my invention. is illustrated in the accompanying drawings wherein- .working parts, and, in the form shown, consists of a base 10 from which upstands a wall lllbordered by a flange 12 which defines upper and lower chambers 13 and 14, connected by a passage 15 which lies to' one side of the machine. The wall 11 also extends laterally upon the side of the machine. which is remote from the passage 15 to provide a bracket 16, and its flanges also extend around at points, such as is denominated as 17, to form a partial en-' closure which is. completed by upper and lower doors 18 and 19 respectively, the former of which has a depending extension 20 and the latter an upstanding extension 21 adapted to provide a closure for the passage 15. In the re ion of the center of this passage is locate a smaller door 22, inthe form of a plate, but, if desired, this plate door may be formed as art of either extension 20 or 21 instead, o as an independent unit. Each door may be hinged to the framework by the usual ears 23 through which passes a pintle, and be provided with any suitable latch for remaining closed. In the drawing the upper and lower doors are represented as open so as to exhibit the interior parts, the upper door 18 being prefer ably flanged on its inner sides as at 24 and carrying an angle bar 25 which depends therefrom in the manner best shown in Fig. 2. I

Within the framework so constructedv are mounted upper and lower wheels 26 and 27 which are located respectively in the cham-.

bers 13 and 14, over which travels an endless band 28 which acts as a saw or cutter for the materials to be operated upon-usually meat in a machine of this kind. A' motor .29 is carried laterally upon the frame in proximity to theexposed partof the saw is a rod 31 which-carries at or near its lower end a laterally extending split sleeve 32 through which the band saw is required to pass, this sleeve housing two members 33 lying within the passage 15 and the other 1 being exposed for operation. Depending from the upper portion of the machine ill/ that lie upon opposite sides of the saw so as to kee its sutface clean, and hold the saw stea yin its movements. When the upper door 18 is closed the angle rod 25 lies adjacent the sawbut on the side thereof which is opposite to the rod 31,'the efiect being to thereby constitute a guardthat will protect the operator against injury from the saw, but whichis removable with openingof the door.

A scraper for each wheel 26 and 27 is also provided, the construction whereof is bestshown in Figs. 5 and 6.. Each scraper is mounted interiorly of the }framework in Proximity o its associated. wheel, andv within the framework as by comprise a hub 35 from which extends a lug 36 having a flat surface on which is mounted a scraper element in the form of a blade or plate 37 slotted longitudinall as at 38 to receive a bolt 39 whose sha is threaded into a suitable opening formed within the lug. The bolt headis suitably tightened upon the sore er blade to hold the same in any. desireda justed position, and the'device in its entirety may be mounted means of a bolt 40 which, in the case of't e lower scraper, passes through the hub 35 to make threaded connection with the wall 11. The upper scraper is preferably bolted to an arm 41 that extends from a plate 42 that is attached to the bearing in which the Wheel 26 ismounted, this arrangement causing the scraper to' move with the wheel when adjustments are effected through manipulation of the handle 30. It will be noted that each scraper is adjustable relative to its associated wheel both angularly and longitudinally, .the preferred adjustment being about as indicated in Fig. 1- where the blade edge lies ver close to the wheel. l

The fiamework bracket 16- is used to support two spaced rails 43 adaptedto receive As shown, the carriage presents an u surface in the form of a table, preferably the wheels '44 of a carriage '45 which receives thefmaterial to be operated upon. This carriage'travels'close to the band saw, as shown in-Fig. 1, and co-operates with a gauge which may take the form of a plate 46 having on its rear side a boss 47 that is suitably socketed to receive the end of a bar 48, preferably square in cross section, the plate being thereby non-rotatably related .to the bar. I have also provided an adjusting screw 49 rotatable through the medium of a hand wheel 50 and havinga swivel connection with the rear side ofthe plate 46, the screw co-opera'ting with an arm 51 which has a fixed connection upon the bar 48, so that the plate ma be moved lengthwise of the bar as desire U on the door plate 22 is carried a box 52 t rou h which is received the opposite end of t e bar 48, a set-screw 53 being provided for holding the bar in any selected adjusted position. It is apparent that the gauge may be set in any desired relation to the band saw either by manipulation of the set-screw 5301 by rotating the hand wheel 50, the latter, of course, effecting the finer adjust ments,-although through a smaller range.

roughened or grooved to resist movement of the material carried thereon, a pan 54 being located preferably beneath the gauge for catching the slices of material that are severed from the part that is held on the carriage.

As it is desirable that the saw should be guided and, steadied as close as possible to bolted or otherwise secured to a part that supports the proximate rail 43; an'upstanding web 56 which supports a fixed head 57 that is extended both laterally and longitudinally beyond the web;and a swinging cap 58 which is hinged to the head as by means of a bolt 59, a thumb-screw 60 being suggested as a means for locking its swinging end in place. The cap is recessed as at 61 to accommodate a gulde block 62 which may be secured to the head as by means of bolts 63, a second guide block 64 being secured to the other as by means of a bolt 65. A narrow space 66 for receiving the band saw is left between the two guide blocks, which extends beyondtheir ends to the proximate'face of the cap, the surrounding faces operating to guide and steady the band saw during movements thereof. As

will be noted from the drawing, the head and cap are offset to overhang beyond the base 56, so that the band saw may clear the member in its entirety. The construction justdescribed is advantageous in that it accomplishes effectively the objects desired, and may be readily opened up and disassembled whenever desired. 1

The machine just described should require no further explanation as to itsoperation which I have already made clear. It embodies the desirable features of a closure for the principal working parts, and of means arranged close to the material be ing acted upon, just above and below it, for holding the band saw to a steady course of travel; a gauge that may be adjusted either fast or slow, and with great accuracy as well; a scraper for keeping each wheel clear of particles delivered to it from the band; and a general arrangement of the several mechanisms such that there is an open space of appreciable magnitude between the upper and lower chambers wherein may be located such parts as the auge and its adjusting mechanism and a catc for receiving the sliced materials.

I claim:

1. In amachine of the kind described, the combination of a framework casing forming two connected and enclosed chambers, a wheel in each chamber, a band saw ex pan.

tending around and between the two wheels I moved away from the saw when the door is opened, substantially as described.

2. In a machine of the kind described, the comblnation of a framework in the form of a closed casing forming two connected chamhers, a Wheel in each chamber, a band saw extending around and between the two Wheels with a portion of itself disposed in open space between the two chambers, a

'swlnglng door in the casing between the Wheel chambers, and a gauge mounted on the door movable towardand from the exopened, substantially as described.
