Original application filed December 14, 1908, Serial No. 467 414. Divided and this application filed November 18, 1911, Serial No. 661,150. Renewed may 11, 1914. Serial No. 837,647.

To all whom it may concern Be it known that l, Enasros E. WINK- Lnr, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Inserting Fasteners; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable'others skilledin the art to which it appertains to make and use the same.

a This invention relates to machines for inserting fasteners and more particularly to bodied in any type of machine which includes fastener insertingmechanism, a plurality of sources of fastener supply therefor, and means for presenting fasteners from the sources of supply to a fastener receiver operatively associated with the inserting mechanism, the presenting means and the receiver being relatively movable, all of which is old, in combination with automatic means controlling the movement of one of the relatively movableparts, preferably said presenting means. It is obvious that with such a construction, the means for controlling the presentation of fasteners to the inserting mechanismis entirely independent of the construction or nature of the source of fastener supply used and therefore may readily be combined-with the source of supply of any machine of the general type described.

As is well known to "those skilled in the art, in the lasting operationlongtacks are inserting means by a raceway pivotally mounted on the tack pot and having two roadways carrying respectively long and short tacks. In machines of the prior art the raceway may be shifted by the operator to bring either one of its roadways into position to deliver tacks to the driver, or it may be brought to an inoperative position where it will not deliver tacks to the driver.

In the best form of the invention at present known to the inventor, as applied to a lasting machine, the means for shifting the raceway comprises a cam, continuously rotated from the main shaft, having suitableconnections by which it moves the raceway to bring one or the other of the two roadways, or delivery chutes. into proper position to deliver tacks to the tack driving mechanism. When it is desired to prevent the delivery of tacks, the raceway is shifted so that neither one of its delivery chutes is in position to deliver tacks to the tack driving mechanism.

The invention will be best understood from a description of one embodiment thereof, such, for instance, as is shown in the accompanying drawings, in which the invention is shown as applied to the lasting machine illustrated and described in the inventors (to-pending application, Serial No. 467,414 filed December 14, 1908. from which the present application has been divided.

The invention is illustrated as applied to a machine of the'type known as the hand method lasting machine wherein a single pair of pincers works the upper over the last, after which it is secured to the last by tacks. It is to be understood. however, that the invention is not limited to use with a lasting machine, which is taken as an example of the general type hereinbcfore described, nor is it limited to the particular form of fastener, in this instance tacks, illustrated and described.

The preferred embodiment of the invention is illustrated in the accompanying drawings, :in which 3- Figure 1 is a side elevation of a lasting machine head; Fig. 2 1s a section on the line 22 of Fig. 1; and Fig. 3 is a detail plan showing particularly the means for automatically shifting the raceways.

The lasting head is of the type commonly known as the consolidated hand method or nigger head, the general construction of which is fully described and illustrated in the United States patents to Ladd and Mc- Feely, 584,744, June 15, 1897; S. W. Ladd, 597,321, January 11, 1898, and J. Cavanagh, Jr., 873,018, December 10, 1907. The machine is caused to perform its lasting and tacking operations by means of the continuously rotating machine shaft 0 which may be driven from any suitable source of power. A full description of the construction and operation of the lasting instrumentalities may be had by reference to the above mentioned patents.

The mechanism for shifting the raceway is actuated by a cam 309, which is continuously rotated by suitable connections to the main shaft 0 of the lasting head. The cam 309 is mounted upon the rear face of a worm gear 289 carried by a counter shaft 288. The counter shaft is journaled in suitable bearings rising from the lasting head support. The worm gear 289 is engaged by a worm 290 (Fig. 2) on a vertical shaft 291, journaled in bearings 291 sustained by the lasting head frame. The shaft 291 is con nected to the shaft 0 by spiral gears 292 and 293, the latter being the spiral gear shown on the main shaft of the patents hereinbefore referred to.

As is usual in lasting machines of this type, the lasting head is provided with a raceway 295 for supplying different size tacks to the driver. This raceway in its construction and mounting is similar to the tack raceway shown in the patent to S. WV. Ladd, No. 696,740 of April 1, 1902, which is provided with a pair of roadways for supplying long and short tacks. Like the construction of the patent referred to, the lower end of the raceway 295 is connected by means of a link 296, to a mechanism for shifting the raceway to a position to supply either the long or the shorttacks to the driver. This operating mechanism as shown in the present invention, differs from that shown in the patent referred to inasmuch as it is automatic instead of being under the control of the operator. The outer end of the link 296 is forked (Fig. 3) and embraces a pin 297 which is journaled in a suitable bearing 298 sustained in a bracket 299 secured to the lasting head frame. The pin 297 rises from a block 300 (Fig. 1) at the lower side of the bearing 298. Above the fork of the link 296 the pin has secured thereto adisk 301 provided with a slot 301 which is out eccentric to the pin 297. This slot is engaged by a small pin 302 which projects upwardly from the link 296. The forks of the link 296 are mounted for a sliding motion between the under side of the disk 301 and the bearing 298. Rotary motion is imparted to the block 300 through a link, or draw rod, 303 connected at one end to a crank arm 304 projecting from the block and at its other end to the outer end of a lever 305 fulcrumed by its inner end on a pin 306 in a bearing 307 carried on the lasting head frame. The lever 305 is provided with a cam roll 308 between its ends, which is engaged by the cam 309. The cam roll is maintained in contact with, its cam by means of a coiled spring 310 secured at one end to the lever 305 and at its other end to the stationary frame work.

The cam 309 is so designed that at the time the toe and heel are being lasted, the lever 305 is moved by the cam in a direction to rotate the block 300 and through the pin and slot connection 301 and 302 to move the link 296 so as to place the roadway which supplies long tacks in a position to deliver 7 its tacks to the tack carrier. The cam also controls the'position of the raceway so that while the sides of the shoe are being lasted, the roadway which supplies short tacks is in a position to supply its tacks to the tack carrier. At certain times in the lasting operation, the raceway should be in aposition so that neither of its roadways can supply tacks to the tack carrier. To this end, the cam 309 is so designed that at the desired times a sutlicient movement is imparted to the link 296 to place the raceway in a position so that neither ofits roadways can supply tacks to the tack carrier. It is apparent that the supply of tacks delivered to the tack driver is thus automatically changed from one side to the other at the proper times as the lasting operation progresses about the periphery of the shoe, and that the delivery of tacks to the driving mechanism and their subsequent waste when it is not desired to drive them in the last is avoided.

While the particulars of construction herein set forth are well suited to one form of the invention, it is not to be understood that these particulars are essential, since they may be variously modified within the skill of the artisan without departing from the true scope of the actual invention as defined in the appended claims.
