FASTENIN Gr-INSERTIN Gr MACHINE.

Specification of Letters Patent.

Patented Aug. 20, 1918.

To all 'zc/1.0m t may concern Be it known that I, 1WILLIAM HERBERT BoRnnN, a citizen of the United States, residing at Winchester, in the county of Mid dlesex and State of lVIassachusetts,have invented certain Improvements in Fastening- Inserting 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.

The present invention relates to fastening inserting machines and particularly to machines adapted to insert metallic reinforces f or protectors in the soles or heels of boots and shoes.

An object of this invention is to provide a machine for presenting and inserting protectors of the type known to the trade as tadpole protectors. lThese protectors have each a head portion comprising laterally eX- tending wings shaped to embrace the stock into which the protector is driven and a shank depending from the head between the wings, a protector of this type being shown in United States Letters Patent No. 889,883 to S. D. Leland, dated June 2, 1908.

An important feature of the invention is improved means for holding the protector in proper position under the driver and for maintaining it in proper position while it is being driven. As illustrated this means is constructed and arranged to prevent axiai turning of the protector while it is beingdriven and thereby insure that it be inserted in the stock with its wings properly disposed. i

Another feature of the invention isa novel awl constructed and arranged to form an opening adapted to receive a protector of the type above described.

These and other features of the invention will be understood from the following specifica-tion which describes in connection with the drawings one embodiment of my invention. f

f Fig. 16 shows in side and front elevation and in plan one of the novel protectors which the machine to be herein described is particularly adapted to handle.

- The invention may be embodied in nailing machines of various types, but is herein shown, for convenience, as applied to a nailing machine of the type shown and described plan view of the parts shown in in United States Patent No. 490,624 dated Jan. 24, 1893.

In the drawings the column 2, head 3 in which the main shaft 5 has its bearings, the swinging frame 6, the foot plate 7, the driver bar 8, the awl bar 12, the rotatable hopper 13, the se aarator lever 15, the means for actuating t 1e driver bar and the awl bar, the means for imparting lateral movement to the frame 6 that the awl may feed the stock, and means for rotating the hopper' and for actuating the lever 15, may be substantially as shown and fully described in said Patent N o. 490,624.

The work support or horn 16, partially shown, is in practice normally pressed upwardly by a suitable spring to clamp the work between the horn and the foot plate and is depressed between successive inserting operations to release the work sufficiently so that it may be fed. The horn may be further depressed by a treadleat the coinpletion of the operation of the machine to allow the work to be removed from the horn and other work applied thereto, the Work support controlling mechanism being substantially that shown in United States Patent No. 265,227, dated Sept. 26, 1882.

To enable protectors having depending shanks to be controlled and driven by the machine referred to, a novel raceway is provided. This raceway comprises front and rear walls or plates 17, 18, with an asserting device 19 shown as a plate rising above the rear wall 18 of said raceway, the assorting device being held in place by suitable screws 20 extending through the front wall 17 of the raceway, said screws also passing through a standard 24 which sustains the shelf 21.

The assorting device 19 is located opposite the lower end of the shelf 21 and projects above the same, the face of said device forming a continuation of the face of the rear wall 18 of the raceway. The upper end of the front wall 17 is separated quite a distance from the rear wall 18 by spacing blocks 22, so that the shank of a protector canfreely enter the passageway between said walls, with the underside of the laterally extending wings of its head resting upon the edge of the. front wall 17, the passageway being not wide enough to permit the head of the protector to pass therethrough. They upper end of the front wall 17 is beveled on opposite sides from a sharp to a gradual bevel, as shown in Figs. 4, 5 and 6, so that it is impossible for aprotector to hang upon said front wall unless the shank of the protector projects into the passageway between the front and rear walls, consequently only those protectors will be positioned properly which drop from the shelf 21 with their shanks projecting downwardly and with the laterally extending wings of their heads projecting away from the asserting device 19. All of the other protectors, namely, those which drop from the shelf head irst or with their laterally extending wings projecting toward the assorting device, will engage the beveled portion of the front wall and be deflected into the hopper. The rear wall 18 of the raceway is slightly higher than the front wall 17 and is adapted to be engaged by the outer side of the head of the protector, so as to prevent the protector from turning as it travels down the raceway with its shank projecting into the passageway and with the underside of its laterally extending wings resting upon the edge of the front wall. The front and rear walls of the raceway are held together by screws 23, spacing blocks being interposed between the walls to determine the width of the passageway. Atf'the extreme upper end of the raceway, resting upon the front wall 17 is a block 25 which is fastened to the assorting device by screws 26, as shown in Fig 3.r

rThe raceway near its upper or receiving end is provided, see Fig. 4, 'with a contracting device, herein shown as a plate 27 adjustably secured by suitable screws 28 to the rear wall 18 of the raceway, said device being made adjustable to enable the width of the raceway groove which receives the shanks of the protectors, to be varied. By adjusting the plate 27, the width of the raceway groove at the entrance thereto may be made to correspond to the thickness of the shank of the protector, so that onlyy those protectors will pass through the entrance to the raceway which present the edges of their Shanks to the groove of the raceway, thus causing the protectors to oc` cupy a position on the raceway with the under sides of their heads resting on the top of the wall 17 and with the wings of the protectors extending in the same direction.

Bearing upon the raceway near the contracting device is a kick-off, shown in Figs. 3 and 6 as a lever 29 pivoted on a screw 30 in the stationary part 32 of the hopper, a suitable spring 33 acting to keep the longer end of the kick-off normally pressed against the upper side of the rear wall 18 of the raceway.

The raceway is connected to and reciprocated with the swinging frame 6 as the latter is moved to effect the feeding of the stock, as provided for bythe disclosure in said Patent No. 265,227. As the raceway is reciprocated any protectors having their shanks but partially in the raceway groove, or any protectors which are lodged improperly on the raceway, are struck by the kick-ofi'I and dislodged from the raceway.

The raceway cover 35, of usual character, has extended beyond its lower end a yielding presser 36, see Figs. 7 and 7.a, which bears on the top of the head of the protector immediately back of the endmost protector neXt to be fed from the raceWay into the driver passage to be described.

The throat of the machine, as shown, comprises several members 39, 40, 41, connected with each other and With the frame 6 by suitable bolts 42 entering holes therein. The member 39 has a ldriver passage 43,` Fig. 8 and an aWl passage 45, and thelnemberv41 forming one side of the driver passage is shown as connected With the membersl 39 and 40 by suitable screws 46 and 48, the screw 48 also serving as a pivot for the protector guide 49 which is yieldingly sustained in the driver passage by a spring 50. The plate 41 is provided with a slot or throat 52 which forms a continuation of the groove in the racevvay, and the shanks of the protectors fed from the racevvay travel through said throat into the driver passage.

The members 39, 40, of the throat are held together by a suitable screw 53, and by a tongue on the member 40 which enters a groove in the member 39, see Fig. 9.

The protectors are delivered singly from the raceWay, by a delivering device consisting of a slotted lever 55 fulcrumed at 56, and having an acting end 58` Which is so shaped and located With relation to the raceway and the driver passage that when the lever 55 is moved from its inoperative fullline position, Fig. 10, into its operative dotted line position, it Will engage the head oii the endmost protector,4 and push said protector longitudinally -from the end of the raceivay into the driver passage. The back of the acting end 58 of the lever serves to retain the other protectors in the raceway,

and Without moving said protectors backivardly or up the racevvay, prevents them from moving down the racevvay until after the delivering device has been restored to its inoperative or full-line position.

The protector delivering device derives its movement from a roller or stud 59 carried on the lower end of the lever 15, said lever being moved in one direction by a cam mounted on the main shaft and in the other direction by a spring 60, as shown in Fig. 3. As soon as the delivering device arrives in its retracted position the blow of the descending driver jars the racevvay so that the protector then held by the yielding presser 36 will be released and Will slide down the rac'evvay toward the delivery end thereof, the pressure of the protectors behind the one so acted upon by the presser being sufficient to canse the endmost protector to slide out from under the presser. i

The protector delivering device in its movement from its full-line position into its dotted line position, Fig. 10, pushes a protector in front of it, from the delivery end of the raceivay,ithe shank o of the protector passing through the slot 52 in the member 41, and deposits the protector in the driver passage with the underside of the head of the protector resting upon a support 61, pivoted at 62 and occupying a position in the driver passage. A spring G3 acts to maintain the support normally in a substantially horizontal position, said support yielding to enable the "protector to descend as the latter is acted uponby the driver 9, the lovver end of Which is grooved or recessed, see Figs. 11 and 13, to straddle a protector guide 49.

. When the driver descends and meets the protector, the support G1 yields, and the in ner side of the shank of the descending pro tector is acted upon by the outer end of the guide 49 which enters the vopen space betiveen the laterally extending Wings of the protector, the acting end of the guide remaining in contact with they innerside of the shank of the protector and with the inner side of the head thereof throughout the driving operation, thus keeping the protector in an upright position, and preventing it from turning axially in the driver passage, so that theprotectors Will all be driven uniformly with the Wings oit their heads in alined position.

To drive a protector of this shape into the Work sustained upon the Work support, it is preferable'irst to make a hole in the stock to receive both the shank and the head of the protector; This is accomplished in the illustrated machine by means of an aivl 65 having a round hole bored in its lower end, see Fig. 14, and beveled upwardly from its lower end more or less, according to the length of the protector and the shape of the head. Such an aWl Will make aA hole for the shank of the protector, and an arc-shaped cut, see Fig. 15, to receive the underside of the head of the protector Where it branches from the shank thus insuring the proper starting of the protector into the Work.

In the operation of the machine the aWl descends and penetrates the stock, and While the avvl is in the stock the frame 6 is moved laterally to feed the stock over the Work support or horn, the horn being at this time slightly depressed. The stock having been fed, the aWl rises and the Work support clamps the stock against the foot plate and holds it clamped While the frame 6 is moved backvvardly tovbring the protector driver into alinement With the hole in the stock made by the avvl. During this operation a protector has` beendelivered from the raceiva-y into driving position upon the yielding shelf or support 61, and the protector driver then descends and engages said protector andV :drives it into the Work, the protector llO leaving the support and straddling the guide 49 which vholds the protector in a "vertical position inthe throat and prevents it from turning axially while it is being driven into the work. y

The edge gage has a connected toothed block 72, which is engaged by the teeth 73 of a long pinion having other teeth 75 on its opposite end and sustained in a` frame. 76 connected to the head 3, by` a screw 77. The frame contains two pinions 78 and 79, the pinion 78 engaging the teetli 75 of the long pinion and being moved by the pinion 79. The pinion 7 9 has a connected crank 80 through which is extended a locking pin or device 82 which coperates with a series of holes 83`forn1ed in the block 76. lWhenever it is desired to change the position of the acting end of the edgev gage 70, the locking pin is withdrawn and the crank is turned to move the gage into the desired position, the locking pin then entering a different hole to retain the gage in its adjusted position.
