To "('11 1227mm it may concern:

Beiit knownthat I,'W1LLLAM B. KEIGH- LEY, acitizen of the United States, residing in "Vineland, New Jersey, have invented certain Improvements in Lasting Apparatus, of which the following is a specification.

One object of my invention is to provide a combination o'fparts whereby a workman is enabled to rapidly draw the upper of a shoe into position and firmly attach it to an insole by means of a suitable adhesive in place of the tacks or other devices previously employed.

I further desire to .provide a relatively simple andconveniently operated apparatus for applyingrsuitable uantities of 'an adhesive to the IlIlSOlG of a shoe so as to provide means whereby 'theproperly stretched upper may be held to said insole prior to the operation whereby it is stitched thereto. It is also desired to provi'de an apparatus whereby .an adhesive may be deposited at the desired point on a shoe during the process of its manufacture, for holding together certain of its parts, and so avoiding the necessity of tacking said parts with the consequent loss of time, danger of breakage of needles,'knives,-and machine parts, in subsequent operations, and the possibility of leaving in the finished .shoe a tack or portion thereof.

Another object of the invention is to provide an apparatus for simplifying the methods of lasting. Y

A further object of my invention is to provide a combined upper -stretching and adhesive-applying device, whereby, when the upper has been brought to proper form and tension, a suitable quantity of adhesive may be delivered at the particular spot desired, and the upper thereafter caused to be firmly ,attachedto t l,1e,.ins o le;, it being also desired to provide novel means for heating r ng ab eama m e s i d i ci 4 i "Thesvebi ends T se'e'ure Specification of Letters Patent.

It is also intera second passage 25, into the upper gwhich the pipe 1% enters, while its .nd is connected to a nozzle or outlet- 3, so placed as to be capable of disug material adjacent to the jaws of pliers. The valve 20 when in its ex- ,ie rearward position, shown in Figs. 1

2, has its forward end terminating at 17p rear side of the passage and also has passage or port 27, which under such noriial conditions, is in line with the passage '1 to which is connected the pipe 16. The roportions of the valve 20 are such that hen it is moved forwardly to the maximum :xtent, its port 27 is brought into line with pa'ssage 25, and in order that the valve normally occupy its rear position, I

Fvide an auxiliary passage 28 leading /m the upper portion of the passage 25 to aie space 29 of the cylindrical bore immeliately to the rear of the screw 24; so thattlthou'gh it is possible to push forwardly .hevalve stem 2O against the air pressure Xisting in the forward end of said bore,

. ,.he removal of the force acting to hold it e imand permits it to be immediately reurned to its normal condition by the action f the air delivered through this auxiliary vassag'e 28 and acting upon its forward end.

Under operating conditions, the reservoir is partially filled with pitch, though other suitable adhesives may be employed; so that they fulfil the condition of quickly hardening after application to a shoe and are capable of properly holding the parts together or in the positions in which they are :placed. Heated air under pressure is then admitted to the upper part of the reservoir v through the pipe 12 and if desired further heat may be provided by a gas flame supplied from the pipe 13. Owing to the heat,

the pitch is maintained in a liquid condition, and under the action of the air pressure is these pipes, forces the pitch out of the valve into and out of the nozzle 26. It will be noted from the drawings, that this nozzle pipe 26 is so placed as to discharge said pitch immediately to the rear of the jaws 3 and 3 so that under operating conditions, it is delivered upon the insole of the shoe at the desired point. Immediately thereafter the operator presses the particular spot of the upper which is held under tension down upon the globule or body of pitch thereon, whereby said part is firmly and immovably held in place. In the meantime the removal of the pressure upon the thumb piece 21 of the valve stem 20 permits the valve to be returned to its normal position against the stop 22, under the action of the air pressure acting upon its forward end through the auxiliary air passage 28, and immediately upon its reaching such position, its cavity is again filled with melted pitch from the pipe 16. The flow of air through the pipe let may be regulated by adjusting the valve 19 and similarly the flow of melted pitch through the pipe 16 I may be regulated by the valve 18. If found necessary, the main cylindrical cavity of the valve casing 5 may be opened for cleaning by the removal of the screw 24:; there being also clean out plugs in the pipe 16. After one of the parts of the upper has been fastened to the insoleas above described, another part immediately adjacent thereto is similarly treated, and so on around the edge of the insole until the lasting operation is completed.

Under working conditions, I have found that the use of pitch as above described, satisfactorily holds the upper to the insole, prior to and during the welting or equivalent operation whereby the two parts are permanently sewed together; it being noted that such means of connecting said parts is greatly superior to the tacking ordinarily employed, especially since there is no danger of breakage of the needles nor necessity for anything similar to the well known tack rcmoving operation. Moreover, there is no possibility of injury to the footof a wearer of the shoe, as has been frequently found to occur when broken tackswere accidentally permitted to remain in the finished shoe.
