To all whom 'it may concern.' l

Be it known that I, WILLIAM B. TURNER, of Melrose, in the county of Middlesex and State of Massachusetts, have invented cer tain new and useful Improvements in Machines for Applying Liquid to Skins, of

This invention has relation to leather treating machinery and more particularly to machines for scouring, seasoning, oiling The present invention has for its object to provide certain improvements in machines of the character illustrated and described in my co-pendingapplication Serial No. 201,177, filed April l, 190e, in which a plurality of members are arranged upon a traveling carrier so as to successively engage and treat a skin which is placed upon a supportmovable toward and from the brushes.

The character of the present improvement will lbe understood from the accompanying drawings and the following specification.

Referring to said drawings-Figure l represents in side elevation a machine embodying the invention. Fig. 2 represents an elevation from the other side of the machine. Fig. 3 represents a front elevation of the machine. F ig. el represents a longitudinal section through the machine. F ig. 5 repre sents a section on the line 5-,5 of `Eig. l. Fig. G represents an enlarged section through the gearing which drives the work support. Fig. 7 represents the work support in position to hold the skin or work in proper relation to the workingl member and the means by which the movement of the work support is stopped. Figs. 8 and 9 represent the clutch mechanism interposed between the gearing and one of the rolls for the traveling work support. Fig. l0 represents a horizontal section through the gearing which drives thc cleaning' roll, beingI a section on the line'lO-JO of Fig. l. Figs. ll and l2 (Sheet illustrate a comb which may be utilized to clean the brushes of the working member. F ig. 13 (Sheet 4) illustrates the method of mounting the brushes on the w rking member.

The machine, to the details of which it will be understood the invention is not limited, comprises side standards 20 2l suitably rThe rear portions of said standards are elongated upwardly and forwardly at an inclination both to the vertical and in the horizontal as indicated at 22. These portions of the frame serve to support the working member which, as will be explained, consists of an endless carrier provided with a plurality of brushes or other.

f skin treating devices or members.

Journaled in theiear ends of the side standards and at the bases of the portions 22 thereof, is the power shaft or main shaft 23, to which power is applied. through the medium. of a large belt pulley 24. 'From this shaft power is applied or transmitted to the various operative portions of the niachine. Journaled in boxes 25 adjustable in guideways at the upper ends of the portions 22 of the standards, is a shaft 26 arranged in parallelism with the main shaft 23. These two shafts are equipped with sprocket wheels 27 28 respectively to receive the chains 29, the links of which are connected at intervals by slats 30 so as to constitute an endless carrier for the skin treating inembers. The portions 22 of the frames are connected by a cross-brace 3l and each is provided with an inwardly projecting flange 32 (as illustrated in Fig. 13) upon which the projecting ends of the slats may rest. The engagement of the slats with these flanges prevents the carriers from sagging at points between the sprocket wheels. Each of these slats is beveled, as clearly illustrated in section in Fig. 1l, and the backs or bars 34 of the brushes 33 are provided with grooved dove-tailed clips 35 which may be engaged with the slats 30. By this construction, each of the brush backs or bases 34 may be removed by sliding it endwise, it being also necessary to permit this to remove the caps at the ends of the portions 22 of the standards. Upon each bar or back 34 are inserted or otherwise suitably secured masses of bristles to form a series of brushes or other members which when in their active positions form a flat surface. The main shaft 23 is rotated in the direction of the arrow ci in Fig. l, so that the traveling endless working member (comprising the endless carrier and' the brushes) is caused to travel so that its active under stretch or portion moves from the shaft 26 toward the shaft 23, the outer'oi upper inactive stretch of the member moving the opposite direction.

The work support or work supporting member is endless. It consists of an apron 36 of vulcanized rubber and canvas or other suitable material which is stretched about rolls 37 38 mounted on shafts 39 40 respectively. These shafts are journaled in a movable frame comprisingsides 41 connected and braced by cross-bars 42. Preferably the boxes 43 for the shaft 40 are bolted to the frame whereas the boxes 44 for the shaft 39 are slidingly mounted on the upper end of the frame, the frame itself being substantially triangular when seen in side elevation as illustrated in Fig. 2. Between the boxes 43 and 44 are screw bars 45 whose ends are oppositely threaded so that by rotating said screw bars, the shaft 39 may be adjusted toward or from the shaft 40 to tighten or loosen the work supporting member 3G.

It will be observed from the drawings that the work support is arranged substantially parallel to but below the working member so as to normally leave a space between them for the insertion of a skin to be treated. The frame for the work support is mounted upon parallel links 46 47 so that the work support may be moved toward and from the working member without destroying its parallelism therewith. The links 46 are secured to a shaft 48 which is journaled in the front portion of the same while the links 47 are loosely fulcrumed on a shaft 49 as illustrated in Fig. 4. Below the upper stretchof the work support 36 there is a flat plate or table 50 which prevents the flat operative stretch thereof from sagging under the weight of the skin and the pressure of the brushes of the working member. This support is secured to the screw bars 45 and is adjustable transversely thereof, being secured after adjustment by lock-nuts 51 on said screw bars. As a matter of detail, it may be said that the table 50 is attached to cross-bars 52 having yokes straddling the screw bars 55 and adapted to be engaged by the lock-nuts 51.

The work support and its frame are moved by power toward -the working member, the

power transmitting devices being under the control-of the operator. To this end, there is arranged in the front of the machine a foot treadle 53 fulcrumed upon a stud 54 projecting forwardly from a cross-bar 55 connecting the standards 20 21. This treadle projects transversely across the machine and is provided with a short depending arm 56 connected by a link 62 tok a lever 57 To understand how this lever' controls the power transmitting devices, it will be necessary to first explain the gearing by which the movement of the work supporting frame is effected.

Referring to Figs. 1, 3, 5 and 10, it will be seen that secured to a shaft 61, substantially midway between its ends, is a driving friction disk 63 in close proximity to a movable driven friction disk 64 loose on the shaft and adapted to he moved longitudinally thereon. The shaft 61 is driven from the shaft 23 by gearing to be hereinafter described. The lever 57, previously referred to, isfulcrumed at 65 upon a bracket projecting inwardly from the side standard 21 and is provided its inner end with a yoke to engage the hub of the friction disk 64 so that, by depressing the lever 53, the disk 64 maybe frictionally engaged with the disk` 63 to cause its rotation. The disk 64 has a crank pin which is connected by an adjustable rod or pitman 66 with an arm 67 rigidly secured to and depending from the shaft 48,

to which it will be remembered the parallel links 46 are rigidly secured. Thus, when the treadle 53 is depressed and the friction disks are engaged, the shaft 43 will be rocked to move the work supporting member into operative or active relation to the working member, thus closing the space between them. By this mechanism, the operator is compelled to exert but little effort in effecting the movement of the work supporting member from an inactive to an active position.

I have stated that the work supporting member is moved by power under the control of the operator in its operative position. It is maintained in this position so long as the operator continues to press down the foot treadle 53, and is returned to inactive or inoperative position by springs 106 106 (see Fig. 5). The rear ends of these springs are attached to brackets 107 projecting laterally from lthe standards 20 21 and their forward ends areconnected to arms 103 which are rigidly secured to the links 47. As the work supporting member moves back into inactive position, it is cushioned by springs 109 '109, which encircle rods 110, whose forward ends are connected to arms 111 rigidly secured to the shaft 48 and depending therefrom. The rear ends' of the rods 110 pass through apertures in lugs 112 depending from the cross-bar 86 as shown in Fig. 4. One end of each spring 109 abuts against a lug 112, whereas the other bears against one or more washers and lock-nuts on said rod 110. For the purpose of limiting the movement of the work support there are additional arms 132 formed on or secured to the parallel links 46 47, which project toward each other as shown in Fig. 2. These arms have projecting screws at their ends adapted to engage cushioned plungers 134 135, arranged in cylinders 136 137, formed on a casting attached to the standard 21. The screws alternately engage the plungers which cushion the force of the impact of the work support as it reaches the limit of its inward or outward movement.

In order that the skin may be properly presented to the working member and spread out, mechanism is provided by means of which the upper stretch of the working member is caused to travel in the same direction as the adjacent stretch of the working member. I find, however, that, for a variety of reasons, the work supporting member should cease its movement when it comes to its operative position. Conse quently mechanism is provided by which the work supporting member is caused to trave-l when the frame is in an inactive position and is brought to a state of rest as soon as the frame and the work supporting member reaches an active or operative position, or is in coactive relation to the working member. The mechanism by which this is accomplished is illustrated in Figs. 1, 3, 5, 6, 7, 8, and 9, to which reference may now be had.

The' roll 38 is rigidly secured upon its shaft 40, which, as previously stated, is ournaled in the links 47. As illustrated in Fig. 6, the links 47 are pivoted upon the bearing 68 through which the shaft 49 extends. Keyed upon the shaft 49 is an intermediate gear 69 which intermeshes with and drives a gear 70 mounted to revolve about the axis of the shaft 40. Said gear 70 is recessed to receive a roll'clutch member 71 which is keyed upon the sh aft 40 and upon whose hub is journaled the hub of the gear 70. This roll clutch member is formed as illustrated in Figs. S and 9 so to receive between it and the rim of the gear 70 a plurality of rolls 172. "When these rolls are in the posi` tion illustrated in Fig. 8, the two members 71 and 70 are clutched together in the usual manner common to clutches of this charac` ter. Then the rolls however are seated in the sockets in the member 71., the two mem` bers are unclutched as illustrated in Fig. 9. In order to move the rolls into their inactive positions, there is ournaled loosely upon the shaft 40 a disk 72 having fingers 73 which project inwardly for engagement. with the rolls. Vhen the disk 72 is loose, the rotation of the gear or member 70 tends to move said rolls into a position where they are wedged between it and the member 71. By interposing an obstacle to the rotation of the plate 72, the rolls will be held from revolution so as to force them back from their wedged positions and the member 71 and the shaft 40 will at once cease rotation. It will be observed that secured to one of the standard portions 22, there is a stop 74 in such position that, when the working member and its 'frame are moved to active position, one of several projections 75, extending from the face of the plate 72, will engage the stop and thus prevent rotation of the shaft 70 and consequently7 effect a cessation of movement of the work support. Thejntermediate gear 69 is driven from the main shaft 23 through the medium of a gear 77 secured to the said main shaft intermeshing with and driving a gear 78 on a stud shaft 79 supported by a standard 20. Secured to said gear 78 is a sprocket wheel 80, connected by a sprocket chain 81 with a sprocket wheel S2, keyed to the shaft 61. Likewise keyed to said shaft 61 is a pinion 83 which engages with and drives the intermediate gear 69. its thus described, the upper stretch of the work supporting member moves down` wardly and rearwardly so as to position a hide or skin thereon and spread it out when the said hide is inserted between it and the working member. When the operator causes the work supporting member to be moved toward the working` member, one of the projections 75 engages the stop 74 as soon as the work supporting member reaches its operative position, and the travel of said work supporting member thereupon immediately ceases. The shaft 61 which also carries the friction disks for moving the work support bodily toward the working member, is thus rotated from the `shaft 23.

In the event that the .machine is employed for applyingseasoning or other liquid to the skin, I utilize a tank or receptacle 84 see Fig. 4) which is supported upon brackets 85 attached to a cross-brace S6 at the rear end of the machine. An applying roll or instrumentality 87 is partially immersed in the liquid and is so arranged that its periphery is engaged by the brushes or other liquid applying devices of the working member as they travel past it, as clearly illustrated in the last-mentioned figure. This roll may be constructed in any convenient manner though I preferably use a brass shell which may or may not be shod with textile material. Said roll is secured upon a shaft S8 journaled in bearings 89 as illustrated in Fig. 5, and on its left-hand projecting end, ias secured to it a friction disk 90 by which rotation is imparted thereto. On a similar end of the shaft 49 there is another friction wheel or disk 91 the face of which is Hush with the face of the friction wheel 90. For the purpese of transmitting rotation from the disk 91 to the disk 90, two friction wheels 92 93, of any suitable material, are secured upon a hub 94, the periphery of the wheel 92 engaging the face of the disk 91 and the periphery of the wheel 93 engaging the face' of the disk 90. The hub of the wheels 92 93 is secured on a shaft 95 arranged from front to rear of the machine and supported in guides 96 97 projecting laterally from the standard 21 as illustrated in Figs. 2 and 3. The shaft 49, as previously stated, is rotated from the main shaft so that, through the friction gearing thus described, the shaft SS and therefore the roll 87 will be rot-ated to apply liquid to the brushes of the working member. By shifting the rod 95 in one die rection or the other, the speed of rotation of the roll SY will be varied, and the amount of liquid delivered thereby will be increased or diminished. The shifting of the rod 95 is accomplished by a hand lever 98 fulcrumed at 99 at lthe front of the machine, as illustrated in 2 and 3. The lower portion of the handle is segmental. and is provided with teeth engaging complemental circular rack teeth 100 formed on a sleeve secured to the rod or shaft 95 so that an oscillation of the handie 98 will effect a reciprocation of the said rod or shaft. Secured to the bracket 101, which supports the pivoted stud 99, is a tooth segment 102, with which may be engaged a looking dog` 103 connected by a lint; 10%1- with a supplemental handle r105 pivoted to lthe main handle 98. The function. of this dog 103 is to hold the handle lever 98 in any position in which it may be moved.

In order that the work supporting member may be cleaned, l". journal in its frame a shaft 113, upon which is secured a cylindrical brush 11d, whose periphery is in engage ment with or impinges upon the understretch of the work supporting member'. The shaft 118 and the brush 114- are rotated so that the periphery of the brush moves in a direction opposite the direction of movement of the contacting portion of the work supporting member by the following mechanism On the right hand end of the shaft 114i is secured a sprocket wheel 115 whichv is driven by a sprocket chain 116 from a sprocket wheel 117 (see Figs. 1 and 10). This sprocitet wheel is keyed upon the hub of a pinion 118, said pinion being journaled loosely upon a stud shaft 119 projecting laterally from the standard 20. rllhe pinion 118 intermeshes with and is driven by a relatively large gear wheel 120 keyed upon the hub of a sprocket wheel 152,1. This sprocket wheel is mounted loosely uponr the shaft 61 and it is driven by sprocket chain 59 tracking upon a sprocket wheel 58 rigidly secured upon the shaft rlfhe sprocket chain 116 is sutlici'ently loose so as not to interfere with the movement of the frame which supports the work supporting mein.- ber :in its movement toward and from the working member. rllhe function of the cleaning brush is to remove from the worlt supporting member any surplus liquid which may remain thereon, and hence a shield 12B is placed in front of and under the brush, said shield being elongated to form a trough which is inclined toward and delivers the surplus liquid into the tank or receptacle till.

attached to the frame for the work supporting member are brackets 125, to the upper ends of which is secured a horizontal table 120. This table projects over the roll eugene 37 and partially over the work supporting member so that a skin may be thrown over the table and portion thereof project into the space between the working member and the worlr suporting member. nWith his hands or with his breast the operator presses the projecting portion of the skin against the edge of the table so as to prevent its being drawn too far forward and downward by the w 'it supporting member.

rhs a matter of convenience, there is placed at the rear end of thermachine a hinge cover or shield 127 (see Fig. et) which covers the lower portion of the working member and conceals the tank or receptacle 84 so as to prevent; the liquid from spattering on the floor.

For the piupose of combing or cleaning the brushes on the working member, I may utilize a con'ib such as illustrated in Fig. 11, consisting of a bar 130 provided with rows of pins or teeth 131. The comb has a handle 132 and the ends of the bar 130 may be re movably held in socket pieces 133 aiiixed to the top of the portions 22 of the side standards.

The operation of the machine may be briefly recapitulated as follows :-The operator throws a skin over the table 126 so that substantially a half thereof falls to the space between the work supporting member and the working member. The work sup porting member, in traveling downward, spreads out the folds of the skin. Firmly holding the skin against the table, the operator depresses the treadle 53 and the work supportin member and its frame are moved by power into an operative position with relation to the working member. 1When the work supporting member reaches its operative position so that the slrin thereon may be engaged by the brushes 'of the working member, one of the projections 75 on the plate 'Y2 strikes the stop Tl and the work supporting member ceases its traveling movement and remains at rest so long as the frame is elevated. The liquid applying roll Si' delivers liquid to the brushes of the work supporti member which engage and rub or otherwise treat the sinn. In case the operator is of the opinion that too much or insutlicient liquid is being 'supplied to the brushes, he moves the handle lever 98 in one direction or the other to vary the speed yof rotation of the roll S7. After that portion of the skin, which is in position to be treated, has been suiiiciently treated, the operator raises his foot from the treadle 53 and the springs 100 move the work supporting member bach to its initial inoperative position. .he it moves forward, the work supporting member commences to travel so that its surface is thoroughly cleaned by the cleaning brush 114i; and the operator reverses the skin and places the untreated portion upon the work supporting member and the operation thus described is repeated.

It will be observed from Fig. d that, when the frame for the work supporting memberI is in its highest and rearmost position, the parallel links 47 4G are substantially vertical so that but little power is required to hold it at this point. 'l'he mounting of the work supporting member upon the parallel links enables the disposition of the work supporting member and the working member with their copcrating stretches in parallelism so that all portions of the skin may be treated with the same degree of pressure, and the pressure may be increased or diminished by varying the force with which the friction plates 64 and 63 are held together by the treadle. and its connections with the disk 6d.

Thilo the invention as illustrated and described is embodied in a liquid applying machine, yet many features thereof may be utilized with equal facility in unhairing, scouring and other leather treating machines, in which event the brushes would be replaced by the proper working members. Consequently the details of the machine may be greatly varied without departing from the spirit. and scope of the invention. lvloreover it should be understood that the phraseology and terms which I employ are for the purpose of description and not of limitation except where the contextl demands it.
