MICHAEL F. BROGAN, 0F LAWRENCE, MASSACHUSETTS, ASSIGNORQ BY MESNE ASSIGN- MENTS, TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY,

A CORPORATION or NEW JERSEY.

SIDE-LASTING- MACHINE.

To all whom it may concern:

Be it known that I, MICHAEL F. BROGAN, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain Improvements in Side-Lasting Machines, 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 lasting machines and is herein illustrated as embodied in a lasting machine of the type adapted to tension a shoe upper about a last progressively and secure the tensioned upper step by step to a shoe insole.

In the manufacture of welted boots and shoes, machines of the general type disclosed in UnitedStates Letters Patent No. 1,011,592, granted Dec. 12,. 1911, on an application of W. J Drey, and known to the trade as Goodyear upper stapling machines, are extensively used to form and insert along the sides of shoes a series of permanent staple fastenings through the upper and channel lip of an insole to replacethe lasting tacks which were driven into the insole to secure the lasted upper temporarily in position in the preceding lasting operation on the shoe. This procedure involves two independent operations on the shoe, namely, lasting and tacking the shoe, and then inserting the permanent staple fastening and removing the lasting tacks.

The present invention has for its principal object to provide a machine in the use of which said two operations of side lasting, and staple fastening the upper can be combined, thus effectin a considerable saving both in the labor and the cost of manufacture of the shoe.

In the illustrated embodiment of the invention the above and other objects are accomplished by providing a stapling machine, such for example as that disclosed in said Letters Patent, with a gripper arranged to seize the upper and cooperate with the staple fastening mechanism in such a manner that Specification of Letters Patent.

ceive a fastening. As herein shown, the gripper is operated to seize the upper by means controlled by a manually effected movement of the staple clenching tool into operative position. 7

Other objects and features of the invention, including certain details of construction and more important combination of parts, will now be described in connection with the accompanyin drawings and the invention will then be defined in the claims.

In the drawings v Figure 1 is a side elevation of a machine embodying the invention in a preferred form;

Fig. 2 is a plan view of the machine shown in Fig. 1 and i Fig. 3 1s a front elevation of a portion of the machine SllOWing the position of the gripper with respect to the fastening clenching tool.

The machine in which the present invention is herein shown comprises staple forming mechanism and staple driving mechanism constructed and arranged to drive a fine wire staple through the upper and channel lip of an insole, and a clenchin tool for clenching the staple upon the inside of the channel lip substantially like the machine disclosed in said Letters Patent, to which reference may be had for a complete description of the construction and operation of the stapling mechanism. As in the machine of said Letters Patent the outside forming member of the staple forming and inserting mechanism carries with it a tucking tongue 2 which projects in front of the forming member and beyond the end of the lower portion of the nose 41: when the outside former has completed its staple forming operation so as to engage the upper just before the staple is inserted and tuck it into the angle of. union between the channel lip and the feather of the insole. The staple clenching tool or anvil. 5, which also serves to clamp the work, is arried by a slide (3' arranged to slide in a guideway 7 in a forked extension 8 of the machine frame. The slide 6 is connected by a link 10 and spring 11 to one arm 12 of a bell crank lever pivoted at 14 to the machine frame, the other arm 16 of the bell crank lever being connected by a treadle rod 18 to a treadle (not shown) in the base of the machine, Depressionof the treadle acts first through the connections described to move the clenching tool 5 into work clamping relation to the nose 4 through which the staples are driven. Further depression of the treadle, permitted by the lost motion provided by the spring 11, actuates the clutch 22 to cause the staple fastening forming and inserting mechanism of the machine to oper ate in substantially the same manner as described in said Letters Patent.

In accordance with this invention a gripper is located in front and laterally of the stapler nose 4 and to one side of the clenching tool 5 (see Fig. 3). This gripper comprises cooperating jaws 24 and 26, the jaw 24 of which is rigidly mounted in a casing 28 pivoted at 30 to-one side of the forked extension 8 of the machine frame. The cooperatingjaw 26 of the gripper is mounted for vertical movement in guideways in the iasing 28 and at its upper end 27 is provided with a stud 31 which is received in a longitudinally extending slot 32 in a lever 34 which is pivotally supported at its opposite end on a pin 36 in an upstanding lug 38 on the frame 8. This lever extends substantially parallel to the link 10 and between the said link and the upper end .27 of the aw 26 as appears in Figs. 2 and 8. The side face of the lever adjacent to the link 10 is provided with a longitudinally extending curved cam slot 40 which receives a roll 42 mounted on the adjacent face of the link 10. It may be seen that endwise movement of the link 10 will oscillate the lever 34 and thereby raise or lower the aw 26 of the gripper. The cam slot is appropriately shaped to insure prompt closing of the gripper during the early part of movement of the link 10. The jaw 26' is normally pressed up wardly by a spring 44 interposed between the top of the casing and a flange 46 on the shank of the jaw. In orderto hold the closed gripperfrom bodily movement toward the stapler nose 4 and also to cause the gripper to pull the upper during the movement of the shoe into fastening receiving position, the casing 28 is providedwith an extension 48 between the outer end of which and the machine frame a stiff compression spring 50 is interposed.

I In the use of the machine above described the assembled shoe is presented to the machine so that the clenching tool 5 is positioned in the channel of the insole and the marginal portion of the shoe upper extends into the jaws of the gripper. Depression of the treadle causes the clenching tool 5 to be moved toward thestapler nose 4 through the link 10 which simultaneously oscillates the lever 34 and causes the jaw 26 of the gripper to be closed to seize the upper. As the shoe is moved by the clenching tool into fastening receiving position against the stapler nose 4 of the inserting mechanism, as shown in low the movement of the shoe toward the stapler nose. Upon further depression of 4 the treadle the tensioned upper and the channel lip are finally clamped in fastening receiving position between the stapler nose 4 and the clenching tool 5 and the clutch is actuated to cause the machine to form and insert a fastening through the upper and channel lip of the insole, the fastening being clenched on the inside of the channel by the clenching tool. The gripper is preferably so controlled by the cam slot 40 that it retains its hold upon the upper until after the fastening operation so that additional tensioning of the upper is secured when the tucking tongue 2 engages the upper and tucks it into the angle of union between the channel lip and the feather of the insole. v

The release of the treadle through its spring (not shown) returns the clenching tool 5 to its initial or inoperative position and opens the gripper whereupon the operation is repeated for lasting and staple fas tening successive portions of the shoe. It will be noted that by utilizing the manually controlled movement of the clenching tool into operative position suflicient time may be taken to manipulate the shoe to secure the insertion of the fastening to the best advantage.
