FASTENING-INSEBTING MACHINE.

Application filed. September 28, 1927. Serial No. 222,642.

This invention relates to fastening inserting machines, and is illustrated as embodied in a machine arranged to sever fastenings from a strip of fastening material and to insort the fastenings inshoe parts.

'My co-pending application for Letters Patent of the United States, Serial No. 34,888, filed June 4:, 1925, discloses and claims the fastening together of shoe parts by means of fibre pegs illustrated as severed from paper twine and driveninto the shoe parts. This manner of securing together shoe parts has proved to be successful for a number of different operations performed in the manufacture of boots and shoes, and it has become apparent that in order to utilize it to the best advantage a number of different types of fastening inserting machines are necessary. Up to the present time it has been found to be necessary to provide all these machines with means of some sort to form holes in the work for reception of the paper pegs and with a chines are provided for forming fastening receiving holes in the work piece, severing fastenings from twine and driving thesevered fastenlngs lnto the holes formed in the work piece. With this object in view a characteristic feature of the inventlon is the organization of the niachme in such a manner that the driver acts-also to sever the pegs from the twine, and as an awl to form fastening receiv- 1 ing holes in the work piece. T he illustrated machine, which constitutes a' preferred em bodiment of the invention, is provided with a gang of drivers arranged simultaneously to insert a plurality of paper pegs to attach a rand to a heel element. In this machine each driver passageis of a cross-section conforming to that ofthe paper peg to be inserted,

wardly into the driver passages whereupon the drivers again descend, each driver severing a peg fromthe paper twine proyectmg into its driver passage and driving the peg into the corresponding hole in the work piece.

ii bile the invention is, for illustrative purposes, disclosed herein with reference to a gang machine organized to insert paper pegs, it should be understood that in various of its aspects it is limited neither to a gang machine nor to a machine for inserting paper pegs.

With the above and other objects and fea- F 3 is a front elevation 011 a larger scale than 2 of the fastening severing and inserting instrumentalities of the machine, part of the machine being shown in cross-section; and

Fig. 4 is a horizontal section on the line 1V-IV of Fig. 2.

The illustrated fastening inserting ma chine is provided with a standard or column 10 carrying at its upper end a pair of shafts 12 upon each of which are mounted four reels 1% of paper twine 16 from which are cut pegs of the character described in said co-pending application, Serial No. 84,888. From the reels 1 1 the paper twine 16 passes about rods 18, 20 carried by inclined arms 22 pivotally mounted on a rod 24 carried by a plate 26 secured to the top of the column 10. Arm's 22 are urged upwardly by springs 28 to apply a certain amount of tension to the papertwine 16 as the latter is fed from the reels. The construction just described is duplicated upon opposite sides of the machine. From the rods 20 the twine 16 passes through openings 80, one of which is. formed in each of a plurality of links 32 pivoted at 3a to the column 10 of the machine. Each link 32 carries an idle roll 36 pressec toward a driven feed roll 38 by a spring 40 andis thereby held in engagement with the paper twine which passes between the rolls and 38 and is fed thereby. The four feedrolls 38 on theleft side of the machine. a all mounted upon a shaft 4-2 while those at the right are mounted upon a shaft MI. Spur gearing 46 connects the shafts 42 oscillated gear segment 116. carriesa work table 118 on which is placed and 44 so that the latter is driven from the former. The shaft 42 is provided also with a ratchet 18 engaged by a pawl 50 carried by an arm 52 connected 1 a link 5&1 to a lever 56 fulcrumed at 58 to the column 10 and car ving a cam roll 60 operating in a cam track 62 formed in a cam member 6 1 carried by a suitably driven shaft 68 having a bearing in the column 10. A spring 70 connected at one end to the tail oi the pawl 50 and at the other end to the link 5% tends to hold the pawl 50 in engagement with the ratchet 18 so that the paper twine 16 is fed step by step as the pawl 50 is oscillated. In order to control the length of the twine fed by each movement of the feed rolls 38, the link 54 is connected to the lever 56 by an adjustable bolt and. slot connection From the feed rolls 36, 38 the strips of paper twine 16 pass through flexible tubular guide members 7 1 to passageways 7 6 (Fig. 8) formed in a nailing die 78 and intersecting with driver passages 80 of the nailing die. The passages 76 through which the paper twine is fed and the driver passages 80 correspond in cross-section to the cross-section of the paper twine and are illustrated as circular.

A gang of drivers 82 is carried by a head 84 mounted on a plunger 86. The plunger 86 is provided with a rack 88 (Fig. 1) engaging a gear segment 90 carried by a bell crank lever 92 fulcrumed at 9 1 to the column 10 and having a depending arm provided vith a cam roll 96 positioned in cam track 98 formed in the cam member 64;. Thus the gang of drivers 82 is caused to reciprocate through the driver passages 80 in timed relation to the operation of the feed rolls 38. The cam track 98 is so formed that the drivers 82 are first given a long stroke, acting as awls and punching fastening receivingholes 100 in the work piece presented to the nailing die 78 and illustrated in Fig. 3 as a heel base 102 and a rand 104. Then the drivers 82 are withdrawn. the strips of twine fed forward into the driver passages 80 and the drivers 82 again moved downwardly, each driver having a short stroke effective to shear a paper peg 106 from the corresponding strip of paper .twinc and to force the peg downwardly throu 'h the driver aassa 'e into the a 31'0- ZTJ D priate hole 100 1n the work piece.

The work nece to be 0 related 11 3011 ma be supported in any suitable manner. As illustrated, the machine is provided with a slide 110 (Fig. 1) mounted for horizontal movement in ways 112 carried by the frame of the machine and provided on its under surface with a rack 11 1 engaging with a suitably The slide 110 the heel and rand which are to be pegged together. A lever 120 fulcrumed at 122 to the slide 110 carries at its left-hand end (as viewed in Fig. 1) a clamp plate 124 arranged to engage the central portion of the heel base 102 (see Fig. 41), and having projections 126 positioned to engage the rand in such a manner as not to inte re with the insertion of the taste-mugs. A spring 128 tends to rock the lever 120 in a colmter-clockwise direction as viewed. in Fig. 1 so as to clamp a heeland rand upon the table 118. \Vhen the slide 110 is withdrawn to the position shown in Fig. 1, however, a. depending linger 130 carried by the lever 120 engages a stationary but adjustable step 132 and rocks the lever 120 in a clockwise direction, compressing spring 128 and holding the clamp 1.24.. awayfrom the work takle 118 so thata heel base and rand may be inserted. When the slide 110 is moved to the left to bring the heel and rand into alinement with the nailing block, the finger 130 leaves the stop 132 and. the clamp plate 124.- is moved downwardly by the spring 128 into engagement with the work.

As illustrated, a die composed of two sections 140, 1 12 is pivoted at 1441, 146 to a bed member 1&8 carried by the column 10. lVhen the slide 110 is in its forward position as shown in F lthe die members 140, 1412 are moved forwardly about pivots 1 14i, 1 16 by a spring-pressed plunger 150 at which time thetween suitable guides 164 carried by the column 10, and is provided with an'upwardly extending arm 166 (F 1g. 1): carrying a cam roll 168 operating in acam track formedin the front of the cam member 64.

vThen the slide 110 is moved forwardly to A the position of Fig. 1 after a group of pegs have been inserted to attach a rand to a heel base, the knife 160 is still positioned in front of the heel base and sweeps the latter from the table 118 as table moves forwardly, the heel base 102 and the rand 104 attached thereto dropping through an opening in the bed member 1 18 to a shute 170 (Fig. 2).
