Our invention relates-to the drying of leather in tanneries and includes among its objects and advantages an improvement in the removal of paste from the plates to which the kips or hides are pasted to be dried. The pasting process as a' whole, in which the present invention is an improvement, is as described in Patent 2,102,667 issued on the inventionof George M. Argabrite Deis usually of the flour and water type, and after the dried hide is stripped from the plate a substantial fraction of the dried paste remains onthe plate and must be removed before another hide can be satisfactorily afllxed. The removal of such paste has in the past been do'ne by hand, and even then with more or less difficulty,
because the type of paste used, after the baking action of the drying process, is slow to soften uncember 21, 1937. In this process the paste used der the action of water, and because any scratch or blemish on the surface of the plate would seriously injure leather later affixed to the plate the manual process, the workmen have bristle brushes of bristles so soft that there isno possibility of mechanical scratching of the plate, and
the entire plate is flooded with a sheet of water,
in which sheet the brushes are pushed around by hand until the paste has softened and comes off.
In the accompanying drawings: Figure l. is an end elevation of a device according to the invention with the adjacent end housing plates removed to show the more clearly;
Figure 2 is a side elevation with the side housing plates removedf Figure 3 is a section as on line 3-3 of Figure 2 showing only the immediately adjacent brushes and spray heads for the sake of clearness;

Figure 6 is a side elevation partly in section as on line 6-6 of Figure 5 of the same brush; and
Figure? is a detail section on line of Figure 6.
In the embodiment of the invention selected for illustration, twin housings l8 and i2 face each other on opposite sides'of the path of movement of the plates H. The plates move through the device on hangers I 6 traveling on the usual tracks l8. Each housing is built up of a. structural steel framework and cover plates. Briefly, each housing has opposed channels 26 at the corners next to the plate and angles 22 at the corners so that a scraping process isimpracticable. In 1 remote from the plate suitably braced by horizontal cross pieces 24 at five different intermediate levels at topvand bottom. At each of the five intermediate levels a beam 26 forms a cross brace in the center of the housing and a support for the remote bearing 28 of the drive shaft 38 for one of the brushes. The enclosure is completed by the front plate 32 which supports the inner bearing 34 for the shaft 30- and also the spray heads 36. The brushes 38-, 40, 42, 44, and 46, on
the right hand side of the plate I4 are staggered as clearly indicated in Figure 2. The upper brush 48 on the opposite side, as clearly indicated in Figure 3 is not opposite the brush 38 but offset to the other side of the housing. The
We have illustr ted suitable means for driving all the brushes. The motor 58 drives the countershaft 60 through a suitable belt and pulley transmission at 62, and from the countershaft'lill the :belts64, run down to pulleys 66 of large diameter on the shafts for the brushes 38 and 48. The brush 40 is driven from the brush 38 by a belt 68 and the brush 42 is driven from the brush 40 by the belt 10. Similarly the belt 12 drives the brush 44, and the belt 14 drives the brush 46. Each of the belts 68 and l8, l2 and I4 is provided x individual brush elements with adjustable tightening means. We have illustrated idler pulleys 18 each supported on a stud bolt 18 and clamped to the vertical leg of the beam 28 by means of the fasteningv nut 88.
\ lilach individual brush comprises a supportingin place'by set screws 81. As clearly indicated in Figures 5 and 6, the inner end of each brush terminates quite a little short of the center of the brush at a point where there is still a little clearance as indicated in Figure 5 at 92 between the inner ends of theadjacent brush elements.
Thus each brush element sweeps over the face of the plate by itself, with a substantial space separating it from each other brush element so that the hot water thrown by the spray heads, which splashes around so much asto fill the entire space between the face plates 32 with a heavy mist or rain, can drench and warm the surface of the paste adhering to the plate during the intervals between the passage of the successive brush elements over the surface of the plate. In Figure 5 the, dotted line 84 indicates the level of the u per edge of the next brush, and the dotted line 96 level with the lower edge of the brush illustrated i's-drawn in to clearly indicate the extent to. which the active areas engaged by the brushes on the plates overlap. It will be apparent that there is no point on the surface of the plate that is not wiped very many times by 90 and wetted down many times during the intervals between successive wipings. Because of this freedom for the access of the hot water to the plate, itis possible to get rid of the paste layer with much better mechanical efficiency and in a much shorter time. To assist in conserving the application of heat to the plate we have provided flexible rubber lips 98 at both ends of the space between the plates 32. These lips yield. to let the advancing edgeof the plate enter but maintain 'the space inside completely housed at all times so far as drafts of cold air or unrestrained splashing out of water is concerned. We have provided doors at 98 at the rear of each enclosurefor accessto the working parts of the mechanism. a With certain types of bristles and certain sizes of plate, it is possible to operate effectively without permitting the shafts 30 to have any longitudinal movement, but under certain conditions with respect to the width of the flanges I00 around the edges of the plate and the stiffness of the individual bristles 98 carried by the brushes, more effective control of the pressure of the brushes against the plate can be obtained by mounting simple coil springs I 02 encircling the shafts 38 and acting in compression between the brushes and the front plate 32. The axial displacements of the shafts 88 when springs I82 are used are so slight that there is no interference with the effective action of the drive belts.
Without further elaboration the foregoing will so fully explain our invention that othersmay.
by applying knowledge current at' the time of application, readily adapt the same for use under various conditions of service. I J
