this invention consists in making provision for automatically cleaning the shedder. This is effected as herein shown by intermittently varying the relation between the shedder and the adjacent portion of the periph ery of the roll between which obstructions are liable to catch. This can be effectively done in many ways and I have herein sho-wn arrangements for varying intermittently the distance between the shedder and the periphery of the roll. By this means the obstructions are wiped from the shedder or squeezed from between the shedder and the roll to dislodge them. In the preferred form the roll has a projection, herein shown as a bar extending lengthwise ofthe roll and embedded inits peripheral face, which intermittent-ly wipes across the shedder. Either the shedder or the roller projection ma andy preferably the shedder will be slidingly mounted and held toward the roll by spring pressure.

A further feature of this invention consistsin heating the cement-by which treatnient it is rendered more Huid so that a thinner coatingcan be applied to the stock and at the same time its sticking power is increased. To this end the cement holder is provided wit-h heating means which may conveniently be an electric heater whereby the cement isjmaintainedin a heated condition without danger of producing a flame, and the cement supplying and applying rolls are warmed by the cement so that the latter is applied to the stock in a heated condition.

It is the practice in using the machine for the operator to take the piece of stock from the applying rollv and apply it directly to the leather to which it is to be attached so that it is caused'to adhere while it is in a heated or warmed condition.. VIt is found that better results can be obtainedby heating the cement as well as al saving in cement effected because 'the smaller quantity of heated cement required stitl'ens the stock less than the quantity required when the cement is applied at a normal temperature.

These and other featuresof the invention.

'including certain details of construction and combinations of parts will be explained in vconnection with the following description of a machine and willbe pointed out more f definitely in the claims.

j Figure l is a front view ofthe machine. Fig. 2 is a vertical section through the lower or cement supplying roll.v Fig. 3 isa left handview of the machine as shown in Fig.

1. Fig. 4 is a vertical section on the line` 4.-4 of Fig. Fig. 5 shows a modification on a similar line. Fig. 6 shows a further modification.

The machine is adaptedxto project up wardly through the surface of a bench o-r table indicated at 1 and is adjustably supadvantageously be arranged to yield,v

ported on a post 2 by a screw 3. The head frame 4 of the machine has a laterally projecting bracket 5 having guideways to receive the runners or slides 6 of a cement receptacle 8 Whichcan be removed for ill' ing or cleaning by pulling it forwardly. An electric hea/ter shown as a cylindrical member 10 is arranged vtoit in a recess formed partiallyin the runners of the cement receptacle and partially in the bracket -5 whereby it locks the receptacle in a predetermined position in the machine. .The main obj ect of this heater is, of course, to heat the cement andobviously also to heat the cement rolls.

The cement receptacle is provided in its upper end faces with notches to receive the bearing blocks 12 of a cement roll shaft 14 upon which turns the cement supplying roll or that roll which dips into the receptacle and lift-s the cement into position to be delivered to the applying roll. .The bearing blocks may be turned by the handle 16 to shift the cement supplying roll from and toward the coperalting roll. A box or cage 20 .is fitted into the cement receptacle and is .formed and arranged to receive that portion of the roll vwhich dips into the cement. One or morefaces of this box are made of wire screen or other suitable material to strain the cement and assist in preventingv particles of foreign matter from reaching the roll.

The preferred construction of the cement supplying rollv is shown in Fig. 2, to consist of end members 25 adapted to turn freely upon the shaft 14 and supporting a cylindrical member 26. -Preferably the peripheral edges of the end blocks 25 project radially lbeyond the periphery surface of the cylindrical member, 26 which latter surface forms the cement carrying face of the roll. The proj ecting'end blocks are adapted to engage and be held yieldingly by the spring plungers 15, before mentioned, against the periphery of the cement applying roll. These projecting end blocks thus constitute a driving connection between the two rolls andM they Vtherefore serve to hold the cement carrying surface of the supplyingroll spaced.

a predetermined distance away from the adacent surface of the other roll to which cement is to be delivered. This 'arrangement insures the delivery of suilicient cement for thepurposes for which this machine is intended even though the cement is of a thin character and is rendered even more fluid by heating it as contemplated by this invention.

The cement applying .roll referredrto is preferably substantially larger than the supplying roll as shown. An object of this ar- Yrangement is to permit the supplying roll 'to be located in convenient position lbelow thebench or table -While the applying roll projects above the table. The shaft of lthe ecampus applying roll 30 is mounted in suitable bearings in the frame 4 and is driven by a worm and gear connection with a u-lley shaft 32, the gear being loose on the s aft and adapted to be connected by a clutch device 34 operated by a lever 35 as shown above in Fig. 3. The frame has a bracket 36 projecting to the left as shown in Fig. l and supporting a scra er or shedder 40 adapted to remove super nous cement from the a plying roll as the cement is carried upwardly into osition to be used. The shedder is located a ove the supplying roll and its lower edge is corrugated or -notched tq facilitate the dripping of the cement back upon the supplying roll. The shedder is adjustably mounted on the bracket 36' as shown in Figs. 1 and 4, being carriedby screws 42 turning in. a block 44, secured to thev bracket, and fastened in adjusted position by lock nuts. The screw extends through an upstanding lug on the lshedder and is 'headed at its front end while a sprin is interposed between said lug andthe lock 44 so that the shedder can yield backwardly or away from the roll but is normally -held yieldingly toward the roll in a position determined by the adjustment of the screw 42. The shedder and a lortion of the periphery of the applying rol are relatively formed to cause t e shedder to be automatically cleaned-or cleared from obstructions such as lint and particles of other foreign matter which may gather between the shedder and the roll. As shown in Fig. 4, the roll carriesa projecting member 46, extending lengthwise thereof across. its eriphery and adapted to engage the shed er and as itwipes upwardly across the edge of the shedder to force the latter backwardly from the roll and clear it from obstructions. The

v#yielding mounting forf'the shedder permits the shedder to move from and toward' the roll as this projection passes it. AIn Fig. 5, the shedder is unyieldingly mounted and the roll carries a projection 48 of yielding material v such as felt. In Fig. 6, the periphery of the roll is provided with a depression or recess 50 into which obstructions may dislodge as the roll turns in the movement of the recessed portion past the shedder.

In the use `of the machine, the operator may conveniently stand in front of the machine with a pile of pieces 4of stock to be cemented on the table at the left of the maguiding it to the roll over the inclined shield 52 which covers the shedder. The operator` rpresses the stock lightly upon the roll permitting the stock to travel forward at the same rateatwhich the roll' turns and then lifting or stripping the stock from the roll.

As the stock is removed `the cement adheres to the nap and thus causes the lnap to stand up from the body of the stock. The cementf coated portion of stock is then laidl down upon the rtion-to which it is to be attached an t-he double portions as they accumulate are piled one upon the other sov and the cloth which gives the double portion of stock desirable characteristics resembling those of much thicker and more expensive leather. Then such stock is used in a shoe the lining covers and conceals the doubling material.
