ALBERTUS TRAVIS, OF JOHNS'IOWN, NEW YORK.

FLESI-IING-MAGHINE.

Application filed November 23, 1916. Serial N 0. 133,069.

To all whom it may concern:

Be it known that I, ALBERTUS TRAVIS, a citizen of the United States, residing at Johnstown, in the county of Fulton and State of New York, have invented a new and useful Fleshing- Machine, of which the following is a specification.

This invention relates to fleshing machines and is more particularly an improvement upon the structure disclosed in an applioation filed by me on May 24, 1916, Serial No. 99,623.

One of the objects of the invention is. to provide a grinding mechanism of improved construction for use in connection with a fleshing cylinder and which mechanism enables the operator quickly to reverse the drive so that the sharpening block will be shifted in one direction or another or be entirely disconnected from its operating means. a j

Another object is to provide means whereby the lower feed roller of the mecha nism is set in motion before it reaches the limit of its movement toward the fleshing cylinder, thus increasing the efliciency of the machine.

V A further object is to improve upon the construction of the means employed for shifting said roller.

With theforegoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope ofiwhat is claimed, without departingfrom the spirit of the invention.

In the accompanying drawings the pre ferred form of shown.

In said drawings Figure 1 is a front elevation of the mabroken away. of-the power the invention has been Fig. 2 is a side elevation transmitting mechanism controlling the op eration of the grinder.

Fig. 6 is a detail view of the adjusting mechanism of the resilient roller.

Fig. 7 is an enlarged inner elevation of the clutch.

Fig. 8 is a section on line 8-8 Fig. 7.

Referring to the figures by characters of reference 1 designates a supporting frame havin side portions 2 extending upwardly theref iom. In these side portions are journaled trunnions 3 extending from the ends of a fieshing cylinder 4: having oppositely pitched scraping blades 4- spirally arranged and meeting midway between the ends of the cylinder, as shown. Arranged on one of these trunnions is a pulley 5 adapted to transmit motion through a belt 6 to a pulley 9 mounted for rotation on a fixed shaft 10. A small pulley 11 rotates with the pulley 9 and is adapted to transmit motion through a belt 12 to a large pulley 13 supported by a transverse shaft 14 extending throughout the width of the machine. A. link 15 couples the two shafts l0 and 14 as shown.

Extending inwardly from the pulley 13 is a hub 16 containing clutch mechanism such as shown in detail in Figs. 7 and 8. By referring to these figures it will be noted that the hub has a recess 19 the wall of which is toothed as at 20. Secured to the shaft 14: so as to work within the recess 19 is an arm 21 to which a pawl 22 is pivotally connected, this pawl being normally pressed outwardly against the toothed wall of recess 19 by a spring 23. An arm 25 extends from the frame of the machine and has a laterally extending finger 26 which constitutes a guide for a clutch member 27. This clutch member is slidably mounted on but does not rotate with the shaft 14-. The clutch member includes oppositely extending arms 28 one of which is forked as at 29 and slidably engages the finger 26. Pins 30 project from the respective arms 28 and extend into the recess 19 where they will be successsively engaged by the pawl 22 dun ingthe rotation of shaft 14. A yoke 31 engages the clutch member 27 and is arranged at the upper end of the lever 17 The foot lever 17 is normally in raised position and, consequently, the pins 30 are normally pressed into the recess 19 where one of them willbe engaged by the pawl 22 thus holding said pawl disengaged from the teeth 20 and allowing the pulley 16 to rotate freely on the shaftll. Thus it will be seen that by mon'ientarily depressing the lever 17, the.

pins 30 will be withdrawn from the recess 19 thus allowing; pawl 22' to spring outwardly into engagement with one or the teeth @onsequently the rotating pulley complete rotation with the pulley 13 and then stopped.

A sprocket 18' is carried by the hub 16" and is engaged by a chain 19 which serves to transmit motion'through a sprocket 20 secured to one end of a shaft 21 on which is arranged a corrugated feed roller 22. Shaft 21 is mounted within spring pressed bearings 23 so as to be capable of yielding upwardly when necessary.

Shaft l l has spaced cams 24: secured there-' on, each cam being 'slightl flattened on its periphery at the point farthest removed from the shaft 14, this flattened portion normally bearing-on: an anti-friction roller 25 carried by a finger 26 which is pivotally connected as at 27 to one arm 28 of a hell" crank lever 29. The other arm' of this bell crank lever has a bearing 30 slidably mounted thereon and in this bearing is journaled the shaft 31 ofayieldable feed roller 32 preferably of rubber and which is normally disposed directly under-the feed roller 22) A lug 83extendsdownwardly from the bearing into an elongated recess 34Jand this lug is engaged slidably by a -ste1n-85 having; a threaded end engaging one end wall of the. recess 3 1, as shown at 36. This stem has a collar 37against which the lug 33 bears and said lug is held against the collar by a spring 88 which engages an adjusting. nut

39*threaded into one-wallof the recess 3e.

Said nut has a head40 byuneans of which" it-can be rotated readily, andthe ste1n35" also has a head; 41 tofacili-tate the rotation thereof;

Extending transversely of "the machine in 1 front of the fieshing-cylinder 4 isav guide beam-l0" having-longitudinal flanges'll along the upper edge thereof slidahly en gaged by a carriage 42.1 on this carriage is adj'ustably mounted a block 43 carrying sharpening element e l-'which'can be in: the

form' of a-block ofcarhorundumor the like.

A screw a5 is employedfor adjusting the blocks 13 and 4L4: toward or from the fleshing" cylinder without correspondingly" moving In other words, each time the foot the carriage '42.. Depending; from. tlieP-carriage is a tongue 16 through which extends a guide. rod Mandafeed screw 4:8. The guide rod andfeed" screw are parallel and extend throughout the width of the machine. The feed screw is provided at one end withaagear 4:9 and another gear. 'is arranged in the same plane therewith on thetrunniorr 8 'of thedleshing cylinder. Pivotally mounted on the screw 48 is an arm. 51 preferably substantially- L shape and 011" this arm= are journaled intermediate gears 52 and 53 which are constantlyin me'slf with' each other. The gear-52is constantly" mesh with the gear- 49, bl1t"the gear-53 *is only in mesh with gear 50*Wh'en'arm'51is1 moved downwardly to one'li'mit of its move= ment.

Thus it'willbe seenthatwlien arm-51 isat one limit of its m0vem'ent, motion will he transmitted in one direction-front gear" 50 to the gear 49 and,xwhen thearmL51Iis" atits other limit 0fmovemenfi'tlreoperation of the gear 49 will be reversed. When arm 51 is in its intermediate position, motion will not be transmitted V to the gear 49".

The rod 4-? not only constitutesa" guide. for the tongue-t6,"butialso serves as a means for actuating the 51; This 'rodis'prd' vided at one end with a. radial arm 54connected by a link55 to thexupper end fof the arm 51. Thus by rocking th'e rodilarin 51 can be shifted to any one of the positions mentioned. and} the operation of the feed screw 48 controlled.

Secured to the shaft'21" atone end is ai head 56 onwhich isSlidably mourited a cylindrical extension; 57 projecting from a conical" friction disk 58. mounted on the shafti2'1 and within theextension 57; thisi'springl bearing at one-end' 'a'gamst the head 56 and at its,=\oth'er. endagainst the disk 58. The shaft 31is provided on .one end"p ortion with affictiOn. disk 60"andthe parts are so proportioned. that when shaft 31 is swung-,npwardly' and forwardly the disk 6 0will.be brought into engagement with the friction disk 158'Iso that "motion .will be transmitted from shaft" 21'to shaft 31.

In order that "the rolirses. on-i-ithe fingers 26 may be held yieldingly f in. contact with the cams 24, brackets time formedintegral with the arms 28 of the bellcranli'lver and carry springs 62 Eaelfspriug' isseated'jin finger 25thereabb've:

A spring, 59- is v.

Motion is preferably transmitted to the Each time the arms 28 are rocked by the cams 2a, the feed roller 32 will move downwardly away from the fleshing cylinder 4,

thus bringing the friction disk 60 out of mesh with the friction disk 58, after which the roller 32 will swing upwardly back to its normal position, bringing the two disks 58 and 60 again into engagement with each other and causing the two rollers 22 and 32 to rotate. When sharpening of the-blades on the fieshing cylinder is desired, the rod a7 is rocked by means of a handle 57, thus to shift one or the other of the gears 52 and 53 into mesh with gear 50. Consequently, the feed screw 48 will be actuated and will cause the carriage 42 to shift longitudinally along the beam a0, thereby dragging the sharpening element 44 along the edges of the blades on the fleshing cylinder.

By providing the sliding bearing 30 for the shaft 31 the roll 32 can be adjusted readily toward or from the fieshing cylinder. The spring tension 38 is employed to automatically adjust the roll to a thick or thin skin. v

For the purpose of yieldingly supporting each arm 28 and the parts carried thereby, a hanger 64: is suspended under each arm 28 from a cross bar 65. In this hanger is slidably mounted a head 66 which bears upwardly against the arm 28 and has a stem 67 surrounded by a spring 68. This spring bears upwardly against the head and engages the hanger so as to yieldingly support the head and the arm 28 engaging thesame. Obviously the downward swinging movement of the arm will be resisted by the yieldingly supported head 66.
