. Befm describing theme-hin@ is detail, itVv ma be mentioned that thepresent machine is, or ,the most part, and exce tin only' the pressureor/and tensioning ro ler andassubstantially identical disclosed in my aforesaid copending application Serial No. 340,844 and reference may made to the said-.r appl numerals employed in the present specification are,v soy numbers indicating li parts, so that the manner inwhich the `present improvement is ap lied `to vthe prior machine may, if more detai ed information is desired, 'readily be l studied by reference to the rior application.

p Again referring to the rawing, the ma` chinecomprises side frames 11 between which are' ivotally disposed upwardly upon `the brac ets 12 andthe brackets 13, parsf'legs workfholder inthe form of a wor and 15` b the'

17 and 18, thefwork table 16, egs 141and' 15 and supporting brackets v12 and, 13 forming a @matura-permitting bodily to 'andfro movement of the work holdingrtlpeblely, v

,v lbodily movement of the work table 16 is effected rearwardly bythe rcoiled spring 19, anchored at onel end in the bracket 12 and at the other end inthe leg 15, against which :Kring action movement may be effected by e bar- 20,`having af wide rest 21 adapted to, body of the operator.v To

' reventrearward tilting action of the work w L lding table, -I provide a lockingmeans or frame, pivotally ,mounted in the bearings 23 on `tluayangularly disposed branch y24 of the e frame. This locking frame com rises the leverfmembers 2 5, whose ,inner en S26 are hollow and in which hollow portions 'are mountbe UV-shaped bracket ication for details ofl the machine here thou ht limmaterial andtherefore not set forth. f n fact, the reference far as possible, identical withv prior application, like l ed spring pressed plungers 27. These levers, two in number, provided adjacent each side vof the frame 11, are caused to be operated in unison by the cross bar 28. It will be observed that rearward movement of the work table 16 is prevented by the plungers 27 engaging the legs 15. To forwardly lock the table, the cross bar 28 is pulled upwardly in a' clockwise direction and when moved past the dead-center, as shown, the work holding table is locked against movement rearwardly.- The spring pressed plunger 27 also servesV to resilientl-y hold the work table in itsv locked position with the work yieldingly held in position.

At the leading or forwardend of the work holding ltable 16 there ismounted a feed roller 3l. Below this, there is mounted a feed or/and pressure or/and tensioning roller 133.v .'Thebearings vfor the latter are carried at'the upper ends of oscillatable arms 134 the lower ends Yof which are afiixed in bearings 135 on the work holding frame. The position of each of the arms 134 is adjustable by 'movement of arod 136 one end of which is pivotally anchored in the arm 134, and the other end ofwhich is Ithreaded and carried in a 137.l A manually adjustable nut138 isA ositioned between the legs ofthe U-shaped racket, and .rotation thereof moves the rod 136 and with it the arm 134 In consequence, besidesthe give oryieldabily ity of-theentire work holdingframe against the spring pressed plungers 27, the roller 133 is itself yieldable, so thatv pressure exerted thereby on the pelt is not critical. For accomplishing the rapidly alternating brushing and ironing operations heretofore set forth, I provide a drum 40 positioned at the upper part of the frame, within the bearings 39, which drum is provided Iwith spiders 41 having end shafts or trunnions 42 arranged to be disposed within the bearings 39 for rotation. The peripheral surface of the drum is provided with alternately spaced ironingplates 43-and brushes 44 arranged in contiguous relationship.l Interiorly of the drum and adjacent the ironing plates 43, there are yprovided heating units 45.

Disposedupwardly of the drum 40, there isj provided thev arcuately formed hood 54.

andthe roller'133.- In this manner, the'presthe bearings 62 in the extremeend of the hood. The feed roller 61 as thus provided invasivaA is arranged inthe operationof themachine to be in contactin relationy withfthe feed roller 3l, mounte ,upon the work holdin' table previously described.4 The hood is pre -f erably made of fexible material'so as to vbe resilient `and therefore adjustable'to vary-1 ing thicknesses 'ofthe fur.' f

The apparatus is provided with a stub shaft pinion or gear 63 driven bythe electric m0- tor, not shown, through themedium ofa gear train contained ivithinlthe cover 65.` MeshingA with the pinion 63, there is provided` a `gear 67to which is aixedva pinion 68 fixed to an' end of the feed roller 31. "The pinion 684 is adapted to mesh with a pinion 69-on the feed:`

parts are in operative ar-` roller 61 when the rangement.

n the shaft of feed roller`31, and rotating with gears 67 `and 68, there 4is fixed a sprocket near 141.

ingv the pressure andftensioning roller 1,33.`

Thesesprocket gears are operativelyconnected by a chain 143.v The chain and s rocket mechanism causes the tensioni-ng rol er 133A to be rotatedwhen" the feed roller `31 is'rotat` ed, and both are rotatedin the same direction as theyshouldbe. f Asis evident from Fig.v 1," the axes of rollers`"31, 133, andbearing 1315, are so related that adjustment of lroller 133 toward or fromthedrum D slight-j ly alters the center tocenter spacing ofrollers 31 and`133, and therefore'of sprockets `141 and 142, and, this'slight variation is readily permitted by s lackness in the chain 1,43.`

The peripheral speed of the pressure roller 133 is preferably made'gretjer than that of the feedroller 31 in order thaltthefpelt may loe placedin tension 'and therefore pressed against the periphery ofthe drum. VThe desired increase in peripheral speed may be obtained by either, or as in this case by both, of

two expedients, first, increasing `the diameter of the roller 133 relative to thatV ofthe feed 'roller 31, and secondly, increasing the diameter of the sprocket 141 relative to that of the sprocket ""ln the particular machine here in question, the peripheral speed of the tensioning roller 133 is made about three times as `great asthat of thefeed roller 31,

but it will be understood thatthe ditference'in f peripheral speed may be variedV over a wide with this recited constructions wiaA be, seen that when thework table 16 is moved'to the position shown, the gear 67 will move into meshing engagement with the pinion 63 and the gea.' 68 with the pinion 69` so that operation of the motor will result in rotating rin unison the feeding and

pressure rollers

31 and 61, respectively, andthe tensioning roller 33. The drum 40 is also rotated by the gear train contained within the cover casing 65,-the said Y drum 40 being rotated, asshownby the arrows, in the directionof feeding movement of n Another sprocket' gear 142 is mounted on the end of the shaftzjcarry the workfed` by lthe feeding' and pressure peripheral speed ofthe drum 40is made very much greater than the peripheral speedsfnii i the feeding and pressure or/and tension rollrollers; To accomplish the desired ends, the

Below the workta'ble 16 there isiprovided a work guiding-apron' 1, disposed below the drum 40 I and the tensionroller 33; fand this is held in position upon the rod 72 andthe upper edge ofi a dust hopper 73,7 which h0p .V Per is connected through a duct 74 to a suc-`` Vtion fan, not shown.`

l For practicing myiinvention in connection with the apparatus just described, a fur plece or pelt, such as`10,is spread-upon the work table 16 when the latter is in retracted` position, the operator spreading 4the same upon this table and then bearing aga-inst the lrest 21'until the `table hasbeen moved for i i ward] tocause the gears and

pinions

68, 69, 63 an 67 to in mesh. The locking frame is then brought to the locking position wby lifteffected by pressureof the operators bodv this .positionfand the motor placed in Arota.-

tion,one end of the pelt will be picked upfby v the feed roller 31 until it is squeezed between the said roller and the feed roller 61. At this point, the edge of the pelt is engaged by the rapidly rotating drum 4.0.l 'The pelt is'r then ing the bar 28 upwardly. If desired, thelocki. 4ing frame need not be used,operation being l against thebar 21.. `llVith the apparatus .in

fed downwardly overthe feed roller31 and i soon reaches thetensioning roller 133-Which keeps the" pelt in direct contact with theidrum tween the rollers 31and133 to vbe pressed and which causes the portion ofthe pelt beagainst the surface of the-drumdhe pelttakf` Y ing the natural curvaturelofthedrum, or,

if it departs. from the natural curvature, does so in such1 a manner as to ff automaticallly obtain the desired pressure of the fur against the drum. In actual operation, this results in a uniform pressure, and; infact seems to permit the peltto fiutter or vibrate veryslightly so as to take the `best natural pressure for the successive brushingand ironing`steps,-and it is found that skinsA treated in the present machine are A given uniformly excellent finish and luster. The rotation of the drum is such that its peripheral speed is far Vgreater than that of the linear movement of the pelt permitted Vby the ,feed roller 31 and the feed roller 61,`so that tinued for the full length of the pelt 10 and this then drops upon the apron`71 and is gath-v' .eredbythe operator'in completely treated pressure will exist during the entire treatl ment o f the fur. In consequenceof `these ad- P 2 vantages, different kinds of fur mayt be fedv condition.

The construction and operation of my imrovement in fur treatin machines will" it cs believed, be apparent rom the fore omg description thereof. The. present macine,

vwhile retainingall of the advantages of my' prior machine, has the additional advanta of not being critical in the adjustment of t e j pressure roll and. in permitting the `fur'` to assume an arcuate shape best adapted lto lit the brushing and'ironing drum, and in allowingv for variation in the position of the skin ac.

'cording to its thickness and texture and length of hair, and according to whether it is in contact with the brushing or ironing portions of the drumso that a more uniform through the machine in rapid succession, without bothering to make adiustments when changing the kind of fur. and uniformlvexcellent results are nevertheless obtained.
