To all whom it may concern:

Be it known that I, GEORGE GoDDU, citizen of the United States, residing at WVinchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Machines for Inserting Fastenings, of which the following de-- scription, in connection with the accompany ing drawings, is a specification, like refer-- ence characters on the drawings indicating like parts in the several figures.

This invention relates to machines for insertingflfastenings and particularly to 'ma-- are of general applicability in the art to which the invention relates.

The invention is herein shown as em- 'bodied"in machine for inserting previously rel-med fastenings which is provided with a plurality ofsources offa'stening supply' and a plurality of fastening guides'leading from the sources of supply," but it will beunderstoodthat the invention isnot 're- 'to remoVe -the-lines of nails which have stricted to use with a machine having more than a single source of fastening supply.

In the machine in which the invention is 1 accumulated in "the' raceways.

In this support-and actuate the inserting mechanism "machine, which is of the type known as ,loose nailing machlne, two raceways' conduct'nails of different lengths'from two nail when the thickness ofthe work is such that suflicient clench would not be provided with a short nail. it is desirable to drive a long nail when the automatic mechanism wouldsupply a Short nail and one of the objects of this invention is to provide imeans .wherebythe operator may at will sovary the operation of ,the automatic mechanism thatv a long nail will be supplied when the normaboperationrof the automatic mechanism would cause, a short nail to be supplied.

In the machine herein-shown, a single treadle operates-both to bring the work support into its operative work supporting position and to actuate the mechanism for insertingfastenings, the! construction, and mode of operationof the single treadle being morefullyshown anddescribed in my December 19, 1911. -In changing the. nails inthe nail pots fromaonekind orlength to another, it is' necessary not only-to remove the nails in the nail pots, which can easily be done'by takingoff' the nail pots but also The usual procedurein emptying the raceways is' to run bllGwIIlttClllIlQW-ltllOllt presenting work to be nailed, the operator either catching ,the nails in ,somerreceptaele asthey are thrown out orallowing them to be thrown. out upon It will be observed that when a single t-readle is employed to raise the work that it will interfere with the discharge of pots and the automatic mechanism operates far as thickness is concerned.

rt-further objectofthe invention. is to provide independent -means for actuating the inserting mechanlsm whereby, whenever it is desired the machine may be run without placing the work supportin worksupporting position. This means is preferably so connected-to themeans for manually connails in the two race ways, it will supply a trolling the shitting'of the raceways that bya single continued movement of said manually operated means the raceways may beshifted and the fastening inserting'mech- -anism then actuated.

The machine in which the nvention is shown as embodied is of the type m'ore'fully described and illustrated in United States Letters Patent to George Goddu No. 1,030,775, granted June 25, 1912, the means for controlling the movements of the work support between work receiving position and work supporting position being illustrated and described in the Letters Patent to George Goddu No.'1,011,941 her'einabove identified, and the mechanism for shifting the double raceway from short na1l posltion to long nail position and vice versa being illustrated and described in a co-pending application of Fred L. MacKenzie, Serial No. 788,19ahof even date herewith.

In the machine herein illustrated, as in the machines of the said Letters Patent hereinabove referred to, a raceway having a plurality of 'nail guiding grooves, or a plurality of conneeted raceways, is so controlled by variations in thickness of the work presented to the machine in position to receive a nail that, when the 'workexceeds' a thickness for which a short nail 1s suitable, the raceway or raceways' will be the horn presses the work, and means by which variations in the position of the movable member of said gaging means will so affect the angular position of ado-uble pawl arranged to cocperate with a slide connect- To this end the machine herein ed to the raceway or raceways that, when the thickness of the work requires a short nail,

the pawl will be tipped in one direction and will engage and force said slide and raceway intoposition to deliver short nails and when thethi'ckness of the work requires a long nail the pawl will be tipped in an- 'other direction to cause the raceway to be moved into positiontodeliver a long nail.

For convenience in comparing the: machine herein disclosed with thoseishown .in the prior patents hereinabove referred to, similar reference numerals will be attached to similar parts. where these parts have not been much changed or are not associated with parts which have undergone much change. The pawl carrying slide 280, upon which is mounted the double pawl 502, is reciprocated to bring said pawl into and out of engagement with one or the other of two shoulders 302, 306, upon a horizontal slide 304, by connections with a bell crank lever 182, comprising a rack 294 mounted upon said slide'280, which rack is engaged by a. segment rack 296 upon an arm 298 of said bell crank 182. Another arm of said bell crank 182 carries a cam roll which entersthe cam groove 18 inthe cam wheel as upon the main shaft 20 of the machine. The connections between the slide 304: and

the double raceway 264 comprise, as shown in the Letters Patent hereinbefore referred to, oppositely threaded rods 308, 310, connected by an adjusting nut 312, the rod 308 being pivotally connected to the lug 31% upon the side of the double raceway. The rod 310 receives in an opening at one end an eccentric pin carried on the lower end of the rock shaft 318 mountedjin a bearing on the bracket 272, saidrock shaft having formed upon its upper end a pinion 320 with which meshes a segment rack 322 (see Fig. 5) formed upon the end of the rock arm 32 1 which is clamped upon the upper end of the rock shaft 326 also mounted in a hearing in the bracket 272 and carrying at its lower end a segment gear 328 which meshes with rack teeth 330 formed upon the slide .304i,t he rack teeth 330 beingformed at an inclination to the slide bar 30t and the bear ings for the rock shafts 326, 318 being correspondingly inclined, this inclination serving to preventbindnig when the inclined raceway is moved. The shifting movement of the slide 304: is sufficient to turn the ec centric pin upon the shaft 318 around from one dead center to the other with respect to the rod 310 so that the raceways are positively shifted and positively held in the positions into which they have been shifted.

The parts thus far described are substantially the same the correspondingparts shown in the patent to Fred LfMacKenzie hereinabove referred to, with the exception that the slide 280 is now provided with an overhanging yoke member 600 which has formed in its split lower end a bearing for the pivot pin 602 of the double pawl 502,

' said pin being clamped in said yoke by a set screw 604. As in the machine shown in the said patent to MacKenzie, the double pawl 502 has attached of it, a semi-circular piece (not shown) which provides upon opposite sides of the axis of said pawl shoulders which coiiperate with dogs 536 and 538 upon the pawl tipper 606, which differs somewhat in its construction and in its connections to the work thickness gaging means from the corresponding part shown in the said. Letters Patent to MacKenzie. The operation of said pawl tipper, so far as the tipping of the pawl is concerned, is substantially identical with the operation of the corresponding part of sand Letters Patent to Mac- Kenzie. The pawl tipper 606 herein shown comprises two arms 608, 610, which carry respectively the dogs 536, 538, and a circular body portion provided with a hub mounted to turn freely upon a shaft 614:.

The pawl tipper is so arranged that it is normally in short nail position, being yieldingly maintained in this position by a spring 636 which is connected at one end to a screw or "iud 63 8 upon the bracket 272 by which the raceway shifting mechanism is carried, and at its other end is bent down so that it enters a socket 6&0 in the outer face of a bell crank lever 642 fulcrumed upon a stud 644: and having at its forward enda short rack 6&6 which engages teeth 64:8 in the periphery of the circular body portion of the pawl tipper 606. Between the stud 6&4: and the pawl tipper 606' the arm of the bell crank 642 is provided with an opening which receives a stud 650 serving as a stop for the vertical movements of said arm, theopening being larger in diameter than the stud 650, whereby move ment of the arm sufficient to rock or permit the rocking of the pawl tipper between its two pawl tipping positions can take place.

to, or forming part The pawl tipper may be moved into its long nail position either by manual means herein to be described, or automatically in ac cordance with the demands of the work. The means for effecting the movement of the pawl tipper in accordance with changes in the thickness of the work which require a long nail, are operated through connec tions with the horn 22 or other work support; said connections being fully described in the copending application of Fred L. lwilacKenzie hereinabove identified.

If it is desired to deliver a long nail when the work is not of such a thickness that the long nail would be automatically supplied,

the raceway or raceways may be shifted into position to deliver the long nail by manually controlled means now to be described. The bell crank lever 6t2hereinabove referred to has a second arm 676 having a stop face678 over which hooks a dog 680 pivotally connected to an arm 682 of .another bell crank fulcrumed at 684 upon a rearward extension of the bracket 27 2; said dog being provided with a slot 686 guided upon a stud or screw 688 for limited longitudinal movement. A second arm 690 of the dog operating bell crank is formed with a vertical bore through which slides a-rod 692. The rod 692 also passes through a vertical bore in a lug 69a projecting laterally from a socket link 697 forming a part of the connections between the starting treadle 3 and the clutch, said connections comprising a lever 380 and other parts more fully shown and described George Goddu, No. 1,030,775 hereinabove referred to. A spring 696 surrounding the rod 692 and located between the lug 694 and the arm 690 tendsto keep said lug and arm in separated relation. A clamp collar 698 clamped upon the rod 692 below the lug 69a is adapted to engage said lug and, through the connections hereinabove re ferred to, to trip the clutch and start the machine. During the first part of this movement of the rod 692 the bell crank lever 690, 682 will be rocked to draw back the dog 680 to throw the pawl tipper into its long nail position. The rod 692 is connected at its lower end by an adjustable clamp 700 to a secondrod 702 pivotally connected at 7 0a to a second treadle 706 fulerumed in the base of the machine, said rod 702 being guided through asleeve 708 formed in the connections between the treadle 3 and the link 697. The front end of the treadle 706 is normally maintained in its elevated position bythe action of the spring 710 surrounding the rod 692 and confined between a clamp collar 712 upon said rod and the bracket 71s projecting from the back of the standard The treadle 3 is normally maintained in its elevated position by a spring 262 confined between a collar 261 upon the rod 260 and the said bracket 714. From the foregoing description it will be seen that, when the horn has been raised and the machine started by depressing the treadle 3 in the usual manner, if it is de sired to deliver a long nail and the position of the work thickness gaging mechanism is not such that a long nail will be automati cally furnished, the pawl tipper can be thrown into its long nail position by simply depressing the forward end of the treadle lever 706. Furthermore, if it is desired to start the machine without raising the horn, continued depression of the forward end of by thistreadle lever, will deliver long nails;

the treadle-706 will serve also to start the machine. v-OW1ng' to the connections above of the raceway,'the machine, when started If it is desired to start the machine without raising the horn and have the machine deliver short nails,th1s may be done by simply pressing the pawl tipper back into its short I nail position against the tension ofthe spring 696. One of the advantages of being able to start the machine with -the horn in its depressed position is that, when it is desired to empty the hoppers or raceways, the machine may be run to throw out the nails in the raceway withouthaving this opera tion interfered with by the horn.
