MACHINE FOR TREATING FURS Fil ed June 12. 1929 2 Sheets-Sheet 2 gwuemtoz Patented Oct. 11, 1932 PATENT OFFICE mc'nmn non TREATING runs Application filed June 12,
This invention relates to a loose fur and for on the pelt treating machine and method, and'has-for an object to provide an'improved machine and method for treating loose fur and fur on the pelt particularly such opera.-
tions a'swhere the loose fur and fur on the pelt is treated with a liquid as in carroting.
It has for another object toprovide a'ma chine and method whereby the loose furand fur on the pelt maybe treated, such as car roted, more uniformly and satisfactorily than possible with the methods of the 'prior art and now enerally in use..
It is a urther object of this invention to rovide a machine which will distribute the iquid at a uniform rate over the loose fur or fur on the pelt, which.rate may be con trolled as desired according to the nature of the loosefur or fur on the pelt to be treated. It is an additional object of the invention to provide a means for raisingthe fur nap as it 1s being sprayed, whereby to insure the penetration of the liquid into the fur.
Withthe foregoing and other objects in view, the invention consists-in certain novel features of constructiomcombinations and arrangements of'parts as well as method'of treating the fur as will be more'fullydescribed in connection with the'accompanying drawings; v In these drawings, v .Fig. 1 is a view of'my fur treating machinetaken from the front or iii-feeding end.

said roller, and hence rapidityof movement of the endless belt 14 may be controlled at will. a
Mounted on the base 10 over the belt 14 is a tank 16 in which the liquid 17 for example so called carroting liquid to be used for treating the fur is kept at a desired depth by the inlet pipe 18. having a float 19 for automatically opening and closing the inlet valve 20 to maintain the-proper depth. When it is necessary to drain the tank 16 for cleaning or other purposes a cut-oil valve.(not shown) in pipe 18 cuts oil? the inflow, and a drain valfie 21 in drain pipe 22 serves to drain the tan Mounted on suitable bearings 22 on the edge of tank '16 is the spindle 23 of a rotary brush 24., the bristles 25'0f which just dip into the carroting or fur treating liquid 17. Braces 26 bolted to the side of tank-16 as at 27 have a cross bar 28 adju'stably'bolted therebetween at 41 to aside of tank 16. Thus as the spindle'23 is rotated, it will be oscillated back and forth. The other end of spindle 23 has splined thereto as at 42 a cammed wheel 43 in which is a circular groove 44 and a cam groove 45. Circular groove 44 has a finger 35 46 held therein by arm 47 bolted to a. side of tank 16 as at 48 and this finger 46 serves to prevent wheel 43 from oscillating with spindle 23, but allows it to rotate therewith, due to its splined connection 42 thereto. An extension 49 affixed to the end of rack 30 has a roller 50 guided in cam groove 45, and rotation of spindle 23 and hence of wheel 43 serves to-oscillate rack 30. The oscillation of rack 30. is in a difi'erent cyclethan the cycle of oscillation of brush 24, due to the fact that the cam rollers 39 and 50 are placed at difi'erent angular degrees about their cam grooves, but this same effect may be procured by using different shaped cams, and the consequent on the material being conveyed by the belt.
WVith the brush 14 turning at a uniform rate, the amount-of spray reaching the material controlling the speed of the belt as it passes under the spray. It will be noted from Fig. 2 that as the bristles pass the rack they are firstbent back by this rack and then released so that they spring forward and flip or throw the liquid down onto the in on the conveyor as. indicated by the dotted lines 17'.
1 Although it has been shown and described that both brush and rack oscillate, it is obvious that the device may be used with only one of these oscillating and the other fixed, as for instance is shown "in the fragmentary viewin Fig. 5, where spindle 23 has a cam .51 in which extension 52 from rack 30 serves to oscillate the rack while the brush does not oscillate.-
the liquid 17 over the belt 14 and the material carried thereon, which in Figs. 1 and 2, is loose fur or fur on the pelt 53. The relative lateral movement of the rack and the brush gives a more uniform distribution of the liq-i place over ro er 13 serves to mix'the liquid somewhat more throughout the fur 53 -'and to discharge it into a conveniently placed receptacle 56.. It will be understood that the liquid 17 may be any suitable liquid such' as nitrate of mercury, or. a mixture of quick silver and nitric acid, but any other desirable liquid may be used. As is well known carroting liquid is used to. rou hen the sur; face of the fibres of the fur or raise a sort of bur or barb on them/so that they felt and stick together better.
Whenthe machine is used to spray furs or pelts 57, that is skins with fur on the pelt, a roller 58 is added over roller 12 and serves to feed the pelts onto belt 14. A pipe 59 is attached across the belt 14 as at60, and compressed air is fed. therein from any suitable source and escapes through holes so placed that the air tends to blow the fur on the skins upright just as the spray 17 reaches it. This allows the spray 17 to penetrate the fur more uniformly and deeply to its roots in the skin. Formerly it was customary to brush the fur by hand in an attempt to get the, liquid cult to get the liquid way down on the .fur
brushed by hand to penetrate, but it wasdifiiand secure uniform treatment, while the pres ent method disclosed'produces a better and The rotation of brush 24 serves to spraymore uniform product. Also, the use of this machine produces the finishedproduct twice as quickly as the previous hand methods, and
is easier and simpler to operate than any of the known hand methods The roller 54-may be used in treating pelts if desired. on the belt may be varied and controlled by parent that this invention providesan im proved method of treating loose fur and fur on the pelt over the previous methods known, and that the machine provided for carrying out this method is simple and easy to operate.
