Application filed December 2, 1909. Serial No; 531,041.

To all whom it may concern:

Be it known that I, FREDERICK G. KING, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings'indicating like parts in the several figures.

This invention-relates to machines for use in the manufacture of boots and shoes and is herein embodied in a machine for use in applying pressure to a shoe and thereafter operating upon the shoe. In the particular instances illustrated, the machine is arranged to apply pressure against the side of a lasted and welted shoe at or adjacent to the rear end of the welt and the front end of the heel seat for forcing the shoe stock into snug relation to the last and for holding it in such relation while-a tack is inserted into the upper and innersole on the shoe bottom for securing the stock. This operation is related .to the shoe lasting operation and is required in the manufacture of good welt shoes because there is necessarily a space at eachside of the shoe between the permanent upper fastening tacks of the heel seat and the ends of 'the'permanent upper fastening seam or inseam, as it is called. This space is left because the sewing machine canno-textend the seam all the way tothe ends of the row of heel seat tacks. If this upper tightening and securing operation is not performed before the liable to spread at these points'during the attaching operation or during subsequent Wear and give to the shoe a loose and ill fitting appearance at the front ends of'the heel stiffener. I I

The present invention'while embodied in a machine particularly adapted. for doing embodiment in different machines.

An important feature of the present invention consists in means, in a machine of the class described, for insuring a predetermined degree. of pressure upon the shoe beforethe subsequent operation for which the machine is arranged can be performed, In the illustrat'ed machine this feature of the invention is embodied in means arranged to require a predetermined amount ofv pressure to be exerted at the side of the shoe before the fastener can be inserted for securing the stock in the positionto which it is pressed.

This illustrated arrangement. is characterized by two features either of which alone -may, in some instances, be employed. In'the first place, the parts are so arranged that a predetermined pressure must be applied in order that the shoe may be moved from the uppertightening position into the proper field of action or the correct position for the tacker to insert the fastening where it will hold the shoe stock. -Also, as herein shown,-

this displacement or movement of the shoe.

permitted whenthe pressure has been at tained, is arranged to effect the starting of the power driven mechanism, which, in this machine, is employed for inserting the securing tack but which in other machines, comprehended in this. invention, mightfbe employed for driving any tool or device for effecting a further operation upon the shoe.

-Other features of the-invention including certain details of construction and ,combinations of parts will be explained in connection with the following description'of the machine and 'will then be pointedout in the claims. i

'Figure 1 is a side elevation of a machine embodying this inventiondn the best, form now known to me: Fig. 2 is a perspectiveview arranged to illustrate particularly the new features of the machine.

The machine comprises a head or fixed frame-work 2 upon which is journaled a cam shaft-4 driven by aclutch which comprises a loose pulley 5 and a cooperating member 6 which is fast to the shaft and with relation to which the pulley'5 is movable axially into and out of driving engage -ment.'- This'axial movmentof the clutch member 5 is effectedby. the spring 8 through a lever 10 pivoted at its lower end to the head and operatively connected to the pulley for moving the latter from and toward the clutch member 6. The lever is normally locked infits retracted position with the clutch members disengaged by a controlling lever 12 having on its rear or-left-hand end, .Fig. 1, an abutment arranged to engage a small abutting face oil the lever 10. The

roe inns tack supplying mechanism to deliver tacks movement from the hopper 23 through the raceway 2-1 into position to be inserted by the driver.

The pressure applying arm or upper tightening device 25 is mounted for endwise in the. head of the machine against the resistance of the forwardly act.- ing' spring 26. The arm is shown as formed in two sections pivotally connected by the ping? to permit the outer end of the arm to be moved vertically toward and from the tacker, its lower position being determined by an adjustable screw 28 against which it is normally held by a leaf spring 31, in Fig. 2. The nozzle of the tacker is preferably stationary and by reason of the provision for vertical movement of the up per tightening device the shoe stock may be firmly compressed between the nozzle and thelast before the tacker is caused to insert the fastening tack, as well as forced inwardly over the edge of the last to tighten it by reason of the displacement of the tightening device laterally with relation to the direction of movement of the driver. The arm 25 has on its front end a suitably shaped work engaging member 30 which may be pivotally mounted and formed as shown to extend into the welt crease and to press against the upper at the side of the shoe near its edge for forcing the shoe stock into snug relation to the last. The pressure arm 25 also has onone side, see Fig. 2, a lug which may be the head of the pin 27 within which is adjustably mounted the threaded pin 35, the inner end of which is tapered, as shown in dotted lines. This pin is arranged to overlie an inclined face on the stem of a vertically movable block 36 upon which is pivotally carried the-tripping device 15. This arrangement provides that when the pressure determined by the adjust men-t of the spring 26 has been applied through the"last against the arm 25 for tightening the upper, the arm will no vc and, through the block 36', pull down the i tripping device 15 and the rear end of the clutch controlling lever 12, thereby permitting lever 10 to be moved by its spring 8 for closing the continuously driven 'clptch mern her 5 against the fast clutch member to cause the tacker to be actuated i ickwardly carrying with it the taper pin The clutch controlling devicis full;

cruined upon a sm, h l end of whiqh has a cam groove by which sale.

the controlling device are moved for ardly during the rotation of the cam shaft to withtrolliug lever from under the hook see i. The spr V raises the controlling lever as soon. as it is freed from the tripping device and in the further rotation of the cam shift the controlling lever moved rearwardly to ra l ng ge the lever 10 and separate the riutch members at the end of one rotation of the camshaft during which a 2, of the tri iping device tacit. has been driven and {mother tacit supplied in position to be driven at the rent machine,operation. The trippin hozvever held down until the w the shoe on arm is relieved r i d there is no possibility of the maclnne making a. sec ond revolution and driving a second tack until the shoe has been moved outwardly to let the arm 25' and the tapered screw 33 come forward again. The device or lever 15 has a tail-piece arranged to engage a.

stop stud ll and the hooked head of the tripping device 15 is beveleth as shown in Fig. 2, to cause it to tip bacltwardly as is raised by the spring 3 to rard position for reengaging lever 12 after the pressure of the shoe against thearin has been relieved and the spring 26 permitted to force said arm and the taper pin 35 forwardly.

The nozzle 45, through which the tacit is drivem is herein shown as-of peculiar form in that it has a rearward extension or lip 46 which extends bEtCkWtUiClly far enough. to prevent the possibility of the endwise movable pressure arm ever rising above the lower end of the nozzle and becoming vaught against it as might otherwise happen when the shoe stock-in the rear of the welt end is presented against the arm. It is sometimes desirable to do this for tightening and securing the shoe stock farther back than the welt extends. I
