The invention relates to machines for applying liquid dressings or seasonings to hides, skins, leather andothe'r similar pieces of work.

Machines of this type commonly employ brushes for applying and distributing the liquid dressing and in time the brushes become worn and must be adjusted with respect to the surface of a work-support to comthe length of the bristles of the brushes. Furthermore, in replacement operations, brushes of different diameters must be adjusted properly with respect to the work support. Where the work support is a drum it is important that the lines of contact of the brushes with the cylindrical surface or the (drum shall remain the same for all diameters of brushes. Accordingly, the present invention provides improved means adapted for adjusting the brushes of a machine of the type referred to so as to maintain the same lines of contact with the drum whether the brushes be largeor small or whether brushes initially of a standard size become'smaller due to wearing away of their cylindrical surfaces. In the illustrated machine each brush is adjustable in a plane passing through the axis of the drum, so that its line of contact with the drum is always the intersection of this plane with the cylindrical surface of the drum. Preferably the supports for each brush are arranged to be adjusted in a plane parallel to the plane just mentioned, and

is provided with a brush-supporting hearing which is offset into the plane passing throughthe drum axis. The advantages of this construction are particularly evident in connection with thickly bri-stled brushes which may be so positioned as to opcrate on the work with the extreme end portions of the bristles, thus minimizing spattering of the liquid time producing a more uniform distribution of the dressing on the'work characterized by "closed *ed over upon dressing and at the same the absence of brush marks upon the finished surface. With brushes thus positioned with respect "to the work it is important that when the proper relationship between a given brush and the curved surface otthe work support has once been established it should not be changed by relative 'lateral'd-isplace- 'Dlffilll) or brush and work support during 'adjustment of the brush nor in the --opera'tion of replacing a worn out brush by anew brush oi' considerably greater diameter. Another advantage of the construction 01 brush supporting and adjusting means "herein -d-isresides in t-he'fact that proper spacing of the brushes with respect to each otheris 410 maintained at all times, thereby insuring, in the co-operation of the brushes with the drum, a more certain andp-erfect feeding of the work than could otherwise be obtained.

This will be'more readily appreciated when it is recalled that in priorconstructions-the shank portions of hides and skins II'O'll'lIi-EEI'G- quently'become 'a source of dificulty 'by' escaping from the controlof the brushes such manner that these portions, and often other portions adjacent thereto, become foldthemselves" and receive the dressing liquid upon'both grain and flesh surfaces, such improper and undesirable'resuits being due, in part at least, to improper spacin'go'i the brushes. Hence, during'adj ustment otthe brush supports or ofth-e bearings carried thereby, the axis oft-he brushremains in the describedpla-ne whichi's radial to the drum and the line of contact of the brush with the drum will always be the same irrespective of the diameter otthe brush.

"Other features 0t the-invention relate to a novel feeding-m table comprising a sectronhavmg spaced vertical ribs designed" to support the work and guide'it to the drum while .at the same time presenting the minimum of surface for receiving any accidental spatterin'g otthe dressingliquid from the liquid applying brush located above the feeding-in table. Preferably, and as illustrated, the table has flanges for strengthening the spaced ribs operative also to collect any spattered liquid material and direct it to a receptacle provided for the purpose.

These and other features of the invention will now be described in detail and pointed out in the appended claims.

In the illustrated machine, which is de signed for applying liquid dressing such as seasoning fluid to hides, skins, leather and the like, there is provided a slanting table 26 over which a piece of work may be fed to a drum 22 mounted for rotation with shr t 24 turning in the direction of the arrow in Fig. 3. For co-operation with the drum 22 there is provided a plurality of brushes 26, 28, 30, 32, each turning in the direction of the arrow in Fig. 3, and each operating to spread a seasoning liquid over the surface of a piece of work while the latter is supported by the drum 22. In addition to spreading the liquid upon the work, the brush 26 serves also as a liquid supplying brush since it is arranged to receive liquid from a distributing roll 34 which is arranged to dip into liquid within a liquid containing pan 36. At the right of the drum 22 there is shown a discharging table 38, the upper portion of which is shown as a sharp edged blade 40 for taking the piece of work from the drum and directing it downwardly along the slanting surface of the table 38 so that it may finally be deposited upon an endless traveling belt 42 which, moving in the direction of the arrow in Fig. 3, carries the work along in a horizontal position where it may be swabbed while it lies in a flat position on, and moves with, the moving belt 42. Usually a man stands at each side of the moving belt and swabs the piece of work, thereby smoothing and finishing the coated surface and touching up any uneven spots. For a more complete disclosure of the endless traveling belt and the purposes for which it is provided, reference should be had to United States Letters Patent No. 1,463,542 granted July 31, 1923, upon application of Arnold A. Angell.

Iileans is provided for adjusting each brush in directions toward and from the drum, the construction being such that this adjustment may be accomplished while maintaining the axis of a given brush in. a plane radial to the drum 22 so that the lines of contact of the brushes with the surface of the drum will remain the same for all diameters of brushes and as the bristles of the brushes become shortened through wear. In the construction shown, the adjusting means for one brush is the same as that for every other brush so that a description of one adjusting mechanism will serve for all. Referring particularly to F 4 of the drawin s it will be observed that a hollow post 50 is pro vided with an interiorly screw threaded socket 52, the post 50 being commonly cast integral with the frame In one instance the post 50 is part of a clamp member 56 which forms part of the bearing for the shaft 24. As stated, the post 50 coi'itains an interiorly screw threaded socket 52 adapted to receive the screw threaded end of a hollow rod 60, the upper end of which is provided with a hand wheel 62 rigidly secured thereto. Extending through the hollow rod 60 is a smaller rod 64, the upper end of which is screw threaded and provided with a winged nut 66. At its lower end the rod 64 is provided with a tapered plug 68 shown in Fig. 4 and also in Figs. 12 and 13, the plug 68 being screw threaded upon the end of the rod 64. T he plug 63 is receivable within a socket in the lower end of the rod 60 which is bored out to provide a socket having tapered surfaces and is also slit at six places as indicated at 70 in Fig. 12, the arrangement being such that, upon pulling the tapered plug 68 inwardly within the socket in the rod 60, s )lit portions 72 of the rod 60 will be spread apart asset's-r to engage firmly. with the surfaces of: the- 64; in the desiredl d'iitec-ti'onto loosen the plug hen this has been aocomp lied, the hollow rod 60 may be t-11 direction, by means of the hand wheel 62, to ustthe associated end of the, brush i with respect to the drum 22 h tterthe-adjus ment has been accomplished the Wing nae:

Where the discharge pipe 118 enters the supply tank 120 there is pro vided a screen 124 for retaining particles of pigment of undesirable size.

provided with a bevel pinion arranged in mesh with bevel gear 132 fixedly secured to a shaft 134 arranged to be flexibly coupled at 136 to the drum shaft 24, the arrangement being such that while the machine is running the stirrer 126 is constantly in operation.

Leading from the bottom of the tank 120 is a pipe 140 which leads to a rotary pump 142 driven by a chain 144 (Fig. 3) from the main shaft of the machine. The pump 142 discharges the iiuid into a vertically arranged pipe 146, a valve controlled outlet being provided at 148 for emptying the whole system of the contained seasoning liquid or of cleansing water when the latter is run through to clean out the circulatory apparatus. Upon inspection of Fig. 14 it will be observed that the vertical pipe 146 is connected by an elbow to the pipe 112 heretofore referred to as the supply pipe for the pan 36. Vertical pipe 146 is provided with an outlet connection at 148 controlled by a valve 150 so that upon proper manipulation of the valve 150 all of the seasoning liquid may be pumped out of the system and emptied into a suitable receptacle placed below the outlet connection 148. This removal of the seasoning liquid is a step preliminary to the cleaning out of the circulatory system by means of wash water introduced into the'tank 120 pumped through the system by the pump 142 and finally discharged through the outlet or drain pipe at 148. The vertical pipe 146 is also provided with a valve 152 for the purpose of controlling the amount of flow of the seasoning liquid and the pressure within the pipe 100. It will be understood that the pump 142 with its connections to the supply pipe 112 constitutes the other part of the means for maintaining the level of the liquid at a predetermined height in the pan 36, the weir 116 being the part first mentioned and described.

Means is provided in the illustrated machine for wiping the drum 22 to remove any of the seasoning liquid which may have been brushed upon exposed portions of the drum while the brushes are operating upon a piece of work which may have left uncovered portions of the drum due to the irregular shape of tne work. Upon reference to Fig. 3 of the drawings it will be observed that the wiper inec ianisin 166 is located in the lower left quadrant of the drum below the feeding-in table 20. The wiper mechanism comprises a supporting bar 162 (Fig. 8) carried by brackets 164 which are shown as integral with side frames 166 of the machine. As most clearly shown in Figs. 9, 10 and 11 of the drawings, the brackets 164 are inclined to the vertical andeach bracket is provided with a lip 168 at its upper end and a lug 170 at its lower end. Thread ed through the lug 170 is a screw 172 provided with a hand wheel 17 4. As shown most clearly in Figs. 8 and 10, the ends of the bar 162 are shaped to engage under the lips 168 of the brackets 164 so that upon manipulation of the screw 172 the bar 162 may be forced into firm engagement with the lips whereby the bar is held fixedly in operative position. To release the bar 162 it is necessary merely to reverse the movement of the screws 172 a sufficient distance to permit the escape of the edges of the bar from the lips 168 when the bar may be turned about its points of contact with the screws to eX- pose a wiper 176 for inspection and for cleaning or for replacement. The wiper 176 is a strip of rubber, although felt or other suitable material may be used. It is fitted into 21 deep groove or slot which extends throughout the greater part oft the length of the supporting bar 162, as will be clear upon an inspection of Fig. 8 of the drawings. In the bottom of this same groove or slot is a bar 178 of metal, though other suitable material may be employ-ed in making the bar. Extending through screw threaded openings in the lower edge of the bar 162 are screw threaded adjusting members 180, each provided with a hand wheel 182. Upon adjusting the screw threaded members 180 in the proper direction the bar 178 is forced toward the mouth of the slot or groove, thus forcing the wiper 176 to project further from the groove in the bar 162, provision being made in this way for causing the wiper to engage the drum 20 and for adjusting the wiper to secure efficient operation thereof in spite of the wear which takes place upon the edge which engages with the drum.

Accumulation of lint and dust from the leather, as well as bristles and waste seasoning liquid from the surface of the drum, collecting behind the wiper, render it necessary to clean the wiper at intervals. To do this the screws 172 are loosened by proper manipulation of the hand wheels 174, thus permitting the bar 162 to slide down the incline of the brackets 164 until the upper edges of the bar 162 are freed from the lips 168. Then the bar 162, with all the parts carried thereby, may be swung about the pivotal points provided by the ends of the screws 172 to such a position that the wipers 176 and parts adjacent thereto are exposed for cleansing. Subsequently, the bar 162 may be swung back into its resting position against the brackets 164 and returned to locked position by proper manipulation of the screws 172 without any loss of adjustment of the wiper 176 with respect to the drum 22. Conveniently, the bar 162 may be utilized as a trough to catch drippings from the feedingin table 20. For this purpose the bar 162 has a flange 190 which is inclined from each end of the .bar toward a median point So as to guide the collected liquid to a discharge pipe 192 (Figs. 3, 8 and 9). Below the lower end-of the discharge pipe 192 is a collecting pan 194 positioned to receive drippings from both the feeding-in table 20 and as the latter 1s being inserted into the machine. Since the brush 26which receives the treating liquor from the distributing roll 34 is located directlyabove the inner end of the table 20 there is the possibility of a certain amount of spattering of the liquid upon the upper end of the table. The chancesof soiling the incoming work from such spattering are minimized by the provision of a plurality of narrow ribs 200 (Figs. 1 and 3) which will hold but little of the liquid and collect none of it, these ribs supporting those parts of the work which might be soiled as a result of spatter-ing of the liquid. Between the ribs 200 are supporting-flanges 202 which also serve to collect liquid spattered from the brush 26 and direct it downwardly through openings 204 through which the liquid may drop to the trough Provided by the wiper bar 162 and its associated flange 1-90 (Fig. 8) as before described. The rest cf the table 20 may have-a plain work supporting surface 206, as shown most clearly in Figs. 1 and 3.

Means is preferably provided for varying the speed of the distributing roll-34 in order that a greater or a less amount of seasoning liquid may befed to the brush,26 for application to a piece of work in accordance with the judgment of the operator. As shown,the distributing roll 34 isprovided wit-ha driving shaft 210 having a hey-way 212 (Figs. ,1 and 2) throughout its end extension 213. Carried by the extended end 213 of the shaft .210 andfree to slide laterally on it is a sleeve 214 having a key which fits ithe key -way so that the sleeve must rotate with the shaft 210. As .a pa-rtof the sleeve 214 is a gear 216,, it being understood thatthe gear may be separable from and rigidly attached to the sleeve 214. Freely rotating on the sleeve214 is a'lever2'18 having a handle 220, the lever 218 carrying at its end opposite the handle 220 a gear 222 shown in Fig. 2 as in mesh with the gear 216 and also with a gear 224 which is the largest gear of a whole series of gears 226 secured to the shaft 24. It will be readily understood then that the Shaft 21.0 of the distributing roll 234 is driven from the drum shaft 24 through the chain of gears 224, 222, 216. if it be desired to change the speed Ofthe shaft 210 the operator may simply depress the handle 220, thereby lifting the gear 222 out of contact with the gear 224 and follow this with a shifting of the sleeve 214 along the extended end2l3 of the shaft 210 until one of the smaller .of the series of gears is located below the gear 222 which may then be lowered into contact with the selected gear. If desired, the sleeve 214 may carry fixedly secured thereto a smaller gear 227 (Fig. 2) with which the gear 222 maybe made to mesh shifting it from the position shown in Fig. 2 to a bearing 230 in the same supportinglever 218. lWlien the gear 222 is in mesh with gear 216, it may be made .tomesh withany one of the'nine gears of the series of gears 22.6, thus providing nine changes of speed; When the gear 222 has been changed so that it is supported by the bearing .230, in which case it is in mesh with the smaller gear 227 on the sleeve 214 it is clear that nine other and distinct changes may be secured when the gear 222 in its new position is caused to mesh with the different gears in the series of gears 226-. By the simple arrangement of gear shift shown-in Figs. 1 and :2 there are provided eighteen changes of speed for-the distributing roll 34. For holding the gear 222 in mesh with the selected gearof the series ofgears 226 there is provided a locking means comprising a link 232 (Fig. 2.) pivoted at 234 to the lever 218 and having a guideway236 (Fig. .6) for aslide block or clamp238 and a bar 240. The bar 240 is rigid with the frame of the ma chine and provides a rigid support to which the link 232 may be locked to hold the gear 222 in mesh with the selected gear .of the series of gears 226. For locking the link 232 to the bar 240 there is provided, as already stated, the slide block .or clamp 288, (Figs. 6 and which has a projecting screw threaded portion 242 provided with a nut 244 to which is ,pivotallysecured a 'handle 246. .Upon manipulating the handle 246 in the direction toztighten the nut 244.0n portion 242, the slideblock or clamp 238 isfixedly clamped to thelink232 and at the same time to the bar 240 through interaction between clamp 238 link 232 and bar 240. Upon turning the nut 244 in the opposite direction, the slide block 238 is released and movedzto releasing position by means of a spring 248 upon astem 250 integral with the slide block or clamp 238.. When it is desired .to shift the lever 218 and the gear 222 carried thereby, the slide block or clamp 238 isfirstreleased through proper manipulation of the handle 246 and the nut 244 operated thereby. Then the lever 218 is shifted along with the sleeve 214 upon the key-slotted end 213 of the shaft 210. During this time the link 232 and the parts carried thereby slide axially of the bar 240. Then the desired gear in the series of gears 226 is reached, the gear 222 is lowered into mesh therewith and during the accompanying movement of the lever 218 the link 232 slides vertically on the bar 240 in a downward direction to permit of the engagement of the gear 222 with the selected gear on the shaft 24. Then tightening of the nut 244 will serve to hold the gear 222 in its new adjusted position. For preventing injury to the gears when gear 222 is lowered into mesh with a selected gear in the series 226 there is provided, in conjunction with each gear, a flat ring, as indicated at 260 (Fig. 1) the outside diameter of which is equal to the pitch diameter of the associated gear. The result is that each time that the gear 222 is lowered into contact with one of the series of gears 226, a ring 262 associated with gear 222 will contact with the surface of the ring associated with the selected gear to bring about a rolling contact which will prevent injury to the gears and yet keep them at proper mesh.

As before stated, the drum 22 is mounted fixedly upon the shaft 24 to rotate therewith, said shaft being provided with a gear wheel 270 (Fig. 3) arranged to mesh with an in termediate pinion 272, which has a running fit on fixed shaft 282. Pinion 272 is fastened to gear 273 and to sprocket wheel 2?5 both rotatable on the same shaft 282, gear 273 being driven by pinion 277 fixedly mounted upon a main driving shaft 276, the latter being provided with a pulley 278 adapted to re eeive a belt arranged to be driven from any suitable source of power (not shown). Fixedly carried by the shaft 276 is a gear 279 (Fig. 2) arranged to be in mesh with a gear 280, which rotates on fixed shaft 282 and is fastened to sprocket wheel 284, around which passes a chain 286, which, at its other end, engages with a sprocket wheel 288 mounted upon a non-rotatable and slidably mounted stub shaft 290 (Figs. 2 and 5). Sprocket wheel 288 is fastened to a sprocket wheel 292 adapted to be engaged by a chain 294 which passes around and in engagement with sprocket wheels 296 secured upon the ends of the brushes 26, 28, 30, brushes 28 and 30 being driven at different speeds, due to a difference in the sizes of the sprocket wheels 296, carried by their respective shafts. Brush 32 is driven separately through chain 298 arranged to be driven from the sprocket 27 5 fastened to the pinion 272 which turns on the fixed shaft 282. For driving the horizontally arranged table belt 42, one of its supporting rolls 300 is secured to a shaft 802 journaled in the frame of the machine and provided with a large gear 304 arranged in mesh with the pinion 272, which in turn meshes with the gear 270 secured to the drum 24, thereby insuring the proper timing of the table belt 42 with respect to the drum 22.

In operating the machine shown in the drawings, the workman places the forward edge portion of a hide or skin or other piece of leather upon the slanting feeding-in table 20 and shoves it upwardly until its forward edge is engaged between the rotating drum 22 and the first brush 26 which are turning in the directions indicated by the arrows in Fig. 3 to feed the work at the same time that the brush 26 applies the dressing liquid which it receives from the distributing roll 34. During the further feed of the piece of work each brush 28, 30, 32 assists both in the feeding of the work by keeping the latter in contact with the drum 22 and in dis tributing the liquid dressing uniformly over the exposed surface of the work. Finally the forward edge of the work reaches the sharp edge 40 of the delivery table 38 which operates to strip the piece of work from the drum 22, the table 38 directing the piece of work down into position upon the table belt 42 which carries it off to the right in Fig. 8, in a horizontal position for inspection and for such hand swabbing of the surface as may be desirable.
