MACHINE FOR APPLYING CEMENT, &,C.

SPECIFICATION forming part of Letters Patent No. 478,031, dated June 28, 1892. Application filed February 8, 1892. Serial No. 420,631. (No model.)

To all whom it may concern:

Be it known that I, HENRIE D. STONE, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Machines for Applying Cement, Paste, zc., of which the `-following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representinglike parts.

In the production of boots or shoes and other leather-work wherein stitches are made in a channel, to be thereafter concealed by turning down over the stitches the lip-of the channel, it is customary to by hand apply to the channel and to its lip cement or paste of some sort to keep the lip in place over the stitches, or it may be other fastenings, as nails or pegs, whichever may have been used to unite the leather. I have devised an automatic machine for this purpose.

The machine illustrating my invention, as herein embodied, shows a sleeve provided at one end with a hollow nose, a feeding-piston, and a valve to control the passage between the sleeve and nose. Preferably the nose will be terminated with a brush or some equivalent substance by whioh to apply a liquid cement or paste. For shoe-work the best results are obtained by the employment of india-rubber cement, it containing naphtha; but owing to the dangerous nature of this cement and stringency of insurance underwriters but a small quantity of naphtha cement can be had at any one time or place in the factory. Usually the barrel of cement is kept at a distance from the factory and the operators get a small amount as needed. The naphtha of the cement, if not kept in a closed vessel, quickly volatilizes, and even when kept in small quantities and exposed, as it must be for the operator to get at it with his brush, the use of this naphtha cement is the source of many fires. In accordance with the plan and mechanism proposed by me, the cementtank may be set at a distance Vfrom the factory and its contents can be taken to the machine through a pipe, and the only portion of the cement which is exposed is that on the brush and after the cement is on the shoe.

I have provided the machine with a feeder in the form of a screw, it acting to feed the cement or brush. l

The machine is also shown as having agage for the edge of the sole, while the brush applies cement or paste in the channel, and so, also, I have shown an air-pipe by which to conductair of proper or desired temperature to the work being cemented or pasted.4

' Figure l, in side elevation, represents a machine embodying in one form my invention. Fig. 2 represents a portion ofthe cement-tank, supposed to be removed from the factory if of a dangerous nature; Fig. 3, a partial rear side elevation; Fig. 4, a Vertical central section taken through the sleeve and nose and the parts within the sleeve, the upper pulley shown in Fig. l being omitted; and Fig. 5 is a top view of the nose and feed-tube E, detached.

The head A, of any suitablev shape,-has proper bearings for the working parts. p

In the form in which I have herein embodied my invention the machine Ahas a hollow sleeve B, provided with. a valve-seat C, and at the lower end of the sleeve is anose D, the inner walls of which will preferably be conical, tapering inwardly toward the lower end of the nose. The nose has within it a conical feed-tube E, held in place by suitable screws F, the bristles constituting the brush G being held in place between the tapering interior of the nose and the tapering exterior of the feedtube. lower end of the sleeve, the Vlatter resting in bearingsA A and having at its upper end a paste and to force it through the ring B', which receives a suitable packing B2, y

acted upon by a' gland B3. In the drawings the sleeve is shown as provided with a pulley B4, which is adapted to be driven by a belt (not shown) extendedfrom some suitable pulley on a driver-shaft. The sleeve contains, as shown, a feeder represented as a screw-pis ton L, having a hollow shank L', through which is extended the valve-rod M', having the Valve m to co-operate withthe seat C, the valve-rod being threaded at its upper end (see Fig. 4) to enable it to be raised or lowered, as desired, to open or more or less close thel outlet in the seat, and thus regulate the quantity of material, cement or otherwise, to be forced out of the nose and brush.

The nose is shown as screwed upon the 4 IOC The sleeve B surrounds the lower end of the pipe N, having an inlet N in communication by suitable pipes N2 Ns with a rescr voir N4 for the naphtha or othercement, which I have mounted upon the frame of the machine an arm having at its outer end a bearing a, in which I have placed the shank of a block a', the upper end of the said shank being screw-threaded and having applied or sccured to it a nut, as a2, a spring a3 surrounding the shank between the nut and the upper end of thebearing. The lower 'end of the block is bifurcated and has adjustably con- E nected with it by a suitable screw, as a4, an edge-gage a5 c, the said edgegage in thisg present embodiment of my invention being;

thereof may be put outermost to contact with i the edge of the shoe having the channel in@ which the liquid cement or paste is to be applied, the opposite ends of the gage being differently shaped to thus better adapt it to different'varieties of work.

The frame-work also supports a suitable;

pipe, as b, in communication with a narrow pipe ZJ', the mouth of which terminates near thepoint where the cement is being applied to the sole or other article. This air-pipe is or will in practice be connected in suitable manner with a fan or blower, (not shown,) which may be of any usual variety.

In the form in which I have shown my invention as embodied in the drawings I have provided for rotating both the sleeve B and the feeder L, and in practice I may rotate either one or both of them, it being possible to obtain excellent results by rotatingI only the sleeve, for when the sleeve rotates and the feeder stands still it will be obvious that the material contained in the sleeve and surrounding` the several blades of the feeder will be made to travel downwardly and be forced out through the valve-opening, provided the valve is lifted. The same result will be obtained by leaving the sleeve at rest and rotating the feeder; but it is preferable to rotate the sleeve, as the brush Works somewhat better if it is rotated, while it acts.V to apply cement or paste or other liquid, whatever may be used in the channel of the sole, or to the leather or other material. rotated, the sleeve or the feeder, it will be obvious that the tendency is to produce a vacuum back of the feeder, so as to draw or suck the liquid substance, cement, paste, or whatever may be used from the suitable tank N4 along through the pipes N3 N2 into the pipe N in communication with the sleeve B. While Vhichever is I shown as double-ended, so that either end.t

I ent articles in the mechanic arts.

the channel-cement is being applied to the channel the operator will hold the lasted and bottomed shoe in his hands with the edge of the sole against the proper gage, the bottom of the sole or the 'parts thereof having the channel being held against the brush or subtsta'nce employed to deliver the cement or paste.

yByemploying a mechanism substantially such as described for applying naphtha cement the fire-risks are greatly lessened and waste of material is also largely obviated, as only just the amount of material which is necessary'to be used is delivered, and that upon the spot where it is required.

By the device described the operator may not only apply cement in the channel, but also to the under side of the lip of the upturned channel.

By adjustment of the valve referred to and timing the speed of rotation of whichever part may be rotated toeffect the ilow of the material the quantityof material discharged at the brush may be thoroughly controlled, and thus obviate too great a discharge of material, which would exnde from the channel when the channel-lip is pressed or rolled down in usual manner.

I desire it to be understood that cement, paste, or other liquid to many differ- So the invention is not to be limited to the use in connection only with channels in shoe-work.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. A nose containing a brush, a connected hollow sleeve and a contained auger-like feeder, and means to rotate one of them, whereby the material contained in the sleeve may be forced therefrom through the nose and be delivered by the brush, substantially as described.
