Referringnow to the drawings yin detail, these illustrate the improved construction' in connection with the usual form of support' ing column or. over-hanging bearing guideQO in 'aline-ment witha bearing 22 at the" top of theV casting- 16, and a third bearingv 24' arranged inside said colnmnor casting 16, these three bearings'bein:0V Vfor vthe purposev of accommodating a Vsection taken on the and detail sections taken 15-15, respectively,

vertically reciprocating bar 26 by which the nailfeeding and driving operations are efafter which the novel features toy portion ofthe rotary disk broken Y casting 16 carryino'A a fixed bracket 18 provide ywith a looV fected.,ashereinafterdescribed. The lower end `of the bar Qfis connectedby a rod 28 to afoot treadle 30 mounted inthe baseof the column 16l (Fig. 1f)l and'held normally elevated byrneans of a lstrong coil spring 32 bar 2S is pr vided wit). a

which is suspended from retaining element 34 in the upper part of said column. The upward movement of the bar 26 is limited by the bearing 24, for w iich purpose the bar is provided with a collar 36 beneath said bearing, a leather butler 38 being inserted between said collar and bearino'.

Associated with tle upper end of the bar 26 is a member 40 which is provided with bearms` portions 4l and 42 slidably engaging said bar intermediate the bearings 2O and and also n. th a bearing 'lug 423 engaging an uprig i at the top of the column le (see l and 3), thereby confining the movement ci said head' inember to a vertical reciprocating motion. The collar 46 adapted, on bars being lifted by the action ot the springl B2, to engage the bearing 4l of the head member 4() and litt the latter into raised position ed the top oit the column 16, as shown in Figs. l and 3, whereas loweringot the treadlc 30 allows the head member to come to rest by gravity upon the top of said column.

The parts comprising the nail feeding nechanism will now be described. A. nail Vreceiving hopper is termed by a cylindrical shell 48 litting 'rictionally offer the upper and outer margin of a hopper bottom casting 50 provided with a lug 5l which is attached by bolts 52 to an angular projection 53 at the top of the head member 40, the arrangement such as vto support the hopper in outwardly inclined relation at the top ot the machine, in which position the nails tend by gravity to occupy the lower side of the hopper and arefted by the action of the feeding means to the raceway which communicates with the upper side of the hopper. Mounted within the hopper upon the upper tace oi the bottom castinr 50 is a rotary nail 'feeding disk 54 provided with a series of upwardly extending nail engagin@ pins 55, the outer portion of the dislrs s tace being also broken by a series or' perorations 55 for engagement with the nails. (See Figs. 4 and 5.) rEhe disk 54 is also formed` with a series ot peripheral notches 57 slightlysmaller than the heads roit the nails 58 extending inward at an angle to the dislrs radius, or backward with re erence to the direction of rotation of said The rear sides ot the notches 57 (with reference to the direction olf; travel) are elevated slightly above their forward sides (Fig. 3) and HCL thon.

A slightly around the inner ends o the notches (see ll) passage into the notches ro'r the nails 58 which are design d to oe trapped oy said notches. The disk 54 rotates with its notched periphery riding over an annular channel 59 in whicn shanlrs of the nails are suswasn their neck portions are engaged the dish is also cupped outV for providing an easy glidirngV innige? within the notches, as illustrated in Fin'. 7. The shell 48 carries a radially projecting battle plate 60 overlying theupward path ot the nails as they approach the mouth ot the raceway, this plate being provided with a restricted opening 6l allowing passage o the nails only at the outer margin of the hopper in line with the channel 59. i pair of tlexible. wire lingers 62 are vpositioned partly across the opening 6l to assist in spreading the nails as well as aiding in engaging them with the notched portions of the disk. lt will also be noted that the outer portion ot the hopper bottom casting 50 has a sloping margin as indicated in Fig. 7, which operates to deflect the nails into engaging relation with the disk notches, and along the upper portion of this sloping margin the same is fitted with a tapered rib 63 Y at the inal approach to the raceway (see Fig. 5), this rib acting in conjunction with said sloping margin to litt the nails and switch them over on to the dislzs periphery and aording them a final opportunity to become seated in the notches 57 and channel 59.

r)The disk 54 is suitably secured to the upper end of a short shalft 64 which is journaled in the hub portion 65 o' the hopper bottom casting 50 (Fig 7 rlhe lower portion of this shaft 64 hassecured thereto a ratchet wheel ('36 on the opposite sides of which a pair of split collars 67 are loosely mounted,

and each of the collars 67 carries a pawlGS the teeth of the ratchet wheel 66; each collar 67 also carries a bevel gear segment 70, the two segments 70 being in mesh with opposite sides of a bevel pinion 7l vjournaled on the end ot a post 72 depending from the casting 50; rJlhe lower split collar 67 is secured fast to the hub portion or a third gear segnient 7 3 which in turn is loosely journaled on the lower end oit the shaft 64 and retained thereon by a collar 74. rlhe gear segment 7 3 meshes with a gear segment 75 loosely mounted between a pair oiI friction washers 76 on a stub shalt 77 carried by the head member 40. One oli' the friction washers 76 is in engagement with the bearing portion of a rocher 78 carried by the inner end of the stub shaft 77, while the other washer 7 6 is embraced by a clamping vasher 39, the clamping torce being applied by a nut 7 9 screwed on to the outer end ot said shaft '77, after which the Wasner 39 may be lined by a set screw 39". pin SO engages a slot 8l in the segment 75 for posiT tioning and limiting the movements of the latter. The rocker arm 78 is provided with one or more slots 82 (see Fig. 3) for engaging a pin 83 carried by an arm 84k secured to the collar 46 on the bar 26, said arm being adjustably secured to said nut by means of a screw 85 land a pin 86 tting in openings 87 of said nut. By means of this construction it is apparent that the throw of the arm 78 may be adjusted to Vary the feeding action which is eifected by the rotation of the disk 54 by means of the described connections, and that this rotation is made substantially continuous for both therup and down movements of the bar 26, since the gear segments operate alternately through the pawls 68 to advance the ratchet wheel 66 for each stroke of said bar 26. Y

That portion of the nail feeding mechanism which acts to transfer the nails from the hopper to the raceway Ileading to the driver will now be described, reference being had more particularly to Figs. 10 to 12. At the upper side of the hopper and at a point in the path of the nails just after they have begun their ldownward disk 54, an opening 88 is provided in the side margin oi" the hopper bottom casting 50 for the mouth of the raceway, in which opening elements are arranged to form a switch passageV for deilecting thev nails from thehopper disk 54 into the raceway, one of these elements being the enlarged end of the rib 63 and the other of said elements being a switch' finger 89. This switch finger 89 is carried by a tilting section 90 of the raceway which is pivoted at 91 to a lug 92 (see F ig. 1) depending from' the base of the hopper. The switch finger 89 operates alongside a iirred iinger 93 projecting inside the hopper4 in overhanging relation to the edge of the disk 54, said finger 98 assisting in shielding the opening into the raceway and also serving as a reinforcing bearing for the free endA of the finger `89. Extending along t-he channel 59 underneath the rib 63 is a slender spring 94 which engages the ShanksV of the nails 58 and operates to retain the same snugly seated in the notches 57 as they approach the switch passage. The tilting raceway section is incased between two housing sections 95 secured to lugs 96 formed on the hopper base at opposite sides of the raceway, and one oi the sections 95 carries a 'leaf spring 97 overlying the tilting section 90 and projecting through the opening .88 for the 'purpose of steadying and directing the movementsl of the nails as they are switched into the raceway, and'also retaining the same in position on the tilting section 90. Normally the tilting section 90 is held in elevated position opposite the opening 88 by means oi an arm 98 carrying' a counterweight 99, as shown in Fig. 10, and is latched in this position by means of a latch element 100 pivoted at 101 to the housing sections 95 and provided with'a notch 102 engaging a pin 103 carried by said tilting section 90. In the switching operation, the nails are deflected from the notches 57 by the means above described on to the tilting section 9,0,v the Shanks of the nails passing movement with theV through narrow passage 104 (see Figs. 5A j pressed against a finger 105 which is carried by the latch100. The pressure upon lthe linger 105 swings the latch 100,resulting in disengagement ofits notch 102 from thepin 103, and as the load of nails carried by the tilting section is suiiicient to overhalance the counterweighted arm 98, said section 90 tips into the inclined position illustrated in F ig. 12, in which position thenails are discharged from the section 90 into the fiXed raceway section 106 e., fixed as regards any angular movement) which is supported in inclined position by a block 107, attached to the head member 40. Iny its tilted vposition the racewayy section 90 is' again latched byV engagement of its pin with a` second notch 108 on the lower end of the latch 100. 2l/'hilt the tilting section isthus latched in tilted position, the switch iinger 89 is retracted from the hopper, as illustrated in Figj12,

and the discharge of the nails from thel hopper ceases until the tilting section returns to raised'position and said .switch finger' is again projected into operative position within the hopper. l r v It is desirable to prevent overloading of the raceway', and the tilting section 90 is provided for this purpose, the 'same act-ing intermittently to replenish the supply in the fixed raceway section, and remaining in tipped position until its load has been completely discharged. The latch element V100, acting as a gravity latclnis readily disengaged by the vibration of the machine, and consequently means isprovided for positively locking said Vlatchuntil the. tilting section has completely discharged its load, Ythisl means comprising a downward extension 109 from the linger 105, which extension 109 is presented at a level with theheads of the nails in the fixed raceway section 106 during the ,latching engagement of the pin 103 with the notch 108, and prevents ydisengagement of said pin and notch untilall the nails have passed below the end ofsaid extension 109, since the latch can not swingv without depressing said extension' into the raceway. As' soon as: the upper yend of the fixed raceway 106 is clear, however.,y said latch becomes disengaged by the ar of the machine, and ythe tilting section 90 is returned to original position bythe action otite counterweighted arm 98. y ,l .n

Referring now more particularly to Figs. 8, 4,. 18k and 14, the yXedk portion 106 Aof the nail raceway is lshown as terminating thenpper face of the block 107 which is provided with a slide passage 11() into which the nails are one by one discharged in iront ot slide bloclr 112 orming part ot a nail separating mechanism which operates toV transier the nails from the raceway to a chute passage 113 (formed in an attachment 131 to the blocli 107) through which the nails gravitate to the nail driving means. rihe block 112 is reciprocated by means of an oscillating segment 114, provided with a nail receiving notch 1111 and connected by a pin 115 with said block, said pin engaging in a slot 116 'formed in the top of the block.. rlllhe nails travel along the passage 110 with their heads supported by the notched portion ot the segment 11e and their shanlis depending` into the passage 110, a curved guard element 111 being mounted around the top margins oi said passage. rfheseginent 11e is secured to the lower en oi" a roel-z shaft 117 supported in a step bearino; in the blo-cl; 107, the upper end ot said ait kbeing` retained by an angle bracket 8 secured to said block 107.v lhe shait 7 is roclred by means oi a irictional drive connection which comprises a. disk 119 loosely applied to the reduced upper end port' nY of said shaft and embraced by a pair oit Vfriction washers 120 which are clamped by 1Keyed metal washers 121 and a clamp nut 122 to the opposite iaces oi said disk. The d' l 119 is provided with a pin 123 carryroller 1211 operating in an inclined iid/away 126 which is attached to the ver 127 carried by the vertically the bar 25 the c. Y reciprocating bar 26. r1`hus as is reciprocated in the driving operation7 'Moment 114e oscillated by the rocking of the shaft 117 thereby reciprocating the bloclr 112 to intermittently transfer the nails from he raceway to the chute passage 113.

The nail driving means comprises a nail driver 128 adjustably mounted in the arm 127 and clamped thereto by a nut 129, the lower end of said rod 128 being suitably recessed to contorni to the shape oi the nail heads. The rod 128 has a plunger movement through a passage 130 in the horizontal arm of the head member 40, beneath which passage is provided an expansible nail receiving throat .termed in two sections 132 pivoted at 133 within a recess 1341 in the head member. rlhe sections 132 1re iiorined with mating channels coperatr to provide a throat passage185 for receri/ing the nails and the driver rod 128, said passage 135 communicating through an opening` 136 in said sections (see Fig. 13) with the chi-te passage 113. rlfhe sections ,l held normally together by springs nel', so that the passage 135 is thereby contracted to the size of the nail heads and driver. The lower end ot said passage 135 is tapered so as to retain the nail until the descent oi the driver forces it out, thereby isomer simultaneously spreading the sections 132 in an obvious manner.

rEhe worlr into which the nails are to be driven is designed to be carried by a horn 1li() of the usual type attached to the top ot a spindle 1411 which is slidingly mounted in a post 142 at the front or" the column 16. rEhis work support is oi an adjustable character, the lower end or' the spindle ing connected by a pivotal linlz 1&3 with a ico-t lever '1-/14 ulcrumed at 1115 at one side or" the column'i7 and being provided at the other side of the column 16 with a pawl projection 116 engaging a ratchet plate 1117. Lateral swingino` motion is afforded the lever 1deon its rulcrurn 115 for disengaging the pawl '146 and adjusting it into dit- ;cerent positions thereby varying said pawl being nient with the plate 147 by 148., ating between a shoulder 150 provided ony the interior ci the post 1412 and a pin 151 the elevation ot the horn, held normally in engagethe action of a on the spindle 1e1, tends to urge the latter d in downward direction in opposition to the action ci the lever 114.

For positioning the edge ci the work" with relation to the line of the nail driving operation, l provide an angular gage element y152 extending on a level with the space just below the mouth of the throat passage 1535, which gage element 152 is carried by ay i-aclr bar 153 provided with a keyway 154 a horizontal liey 155 on one side :tace ci' the horizontal arm ot the head meni- 07 said bar being retained in sliding ennent with said lrey by a pair oi bracket j s 156. Between these bracket plates 15G.. projecting trom the same 'face or" th` ifneinber9 is a pin 158 for journalits element 152 may be readily shifted to any desired position within the limits oi the rack bars movements.

it, 161 is also provided for suitably g the spacing distance between the s as they are driven7 this gage being piv otaly supported iroin a bracket plate 162 attached to the horizontal arm of the head rieniber 10 on the side opposite thereoi1 from the raceway., or on that the wort; ted during the driving operation. 'flie lower end or'.' this gage 161 is on a level with the mouth of the throat passage 135, and adapted to rest on KVthe tace cit the work and abut against the edges ci the nails after they are driven.v This gage is adjusted by means oi'i a screw 163ezitendthropgn the geandcarrying a nut 16d by which` tne gage is forced up against a spring which is coiled around the screw between the gage and the head member 110.

side toward whichy The 'operation of the machine will be readily understood from theY foregoing description, but the same may be briefly summarized as follows. `T he purpose of the machine, as illustrated, is especially'designed for use in the driving of nails of the type shown, having a large head, into the soles or heels of boots or shoes of any type or material, such as leather or wood, or a combination of such materials. A quantity of the hob nails 58 are placed in the hopper, and the horn 140 is adjusted to the proper height according to the thickness of the stock, by means of the lever 144. The edge of the work is rested against the face of the gage 152, and this gage is adjusted according to the distance which it is desired to space the line of nails from the edge of the work. The treadle 30 is now depressed a sufficient number of times to obtain a supply of the nails in the raceway. The operation of this leverV acts through the described connections to the hopper disk 54 to rotate said disk, and this rotationis substantially continuous, since the gear and ratchet elements are operated by both the Vup and down movements of the vertically reciprocating bar 26. One particular advantage of this feature of the construction is that a slower feeding movement of the nails within the hopper is rendered possible by the practicallycontinuous driving action, and hence there is less likelihood of the nails clogging and obstructing the feeding mechanism. The rotation of the disk feeds the nails from the hopper into the tilting raceway section 90, which remainslatched until said section is filled, and then automatically trips to discharge the nails into the fixed raceway section 106. Nails are now transferred from the'lower end of the raceway by the action of the nail separating means above described, the loscillating segment 114 moving thenails one-by one to the upper end of the chute passage 113, through which they drop into the lsectional throat 135 between each stroke of the driver 128. In the throat 135 the nail is held in position for the drivers action with the point of the nail almost in contact with the work at the moment; the drivers action begins. The driving operation -is carried out by lowering of the treadle y 30, the initial movement of which lowers the head member 40, bringing the tip of the sectional throat'l against the stock, whereupon the continued movement of the lever or treadle depresses the driver 128 and drives the nail, the throat sections 132 spreading apart to permit the discharge ofthe nail. `After the first nail hasbeen driven, the work is moved to bring said nail up against the gage 161, which is adjusted according to the distance it isdesiredto space the nails apart,

the worlr being then held with said driven nail againstthe gage 161 during the driving Y v I i i y dunne mehenlsmi lierre? .'PlQVlf of the nextl nail.

. ply of the nails, for which purpose the switch element 89 is again projected into operative position fordeflecting the nails from the hopper into the mouth of the racewa-y. T his interruption in the flow of the nails into the raceway prevents overloading of the raceway and results'in vbetter and more even move,u

ment of the nails by preventing them from crowding each vother or getting out of line and clogging in the raceway.

It is thus apparent that apractical and efficient construction has been provided for embodying the proposed improvements.,` An improved and substantially continuous nail feeding action is effected by themeans shown, and this is accompanied by complete safety inthe drive transmission, since the friction drive to the hopper` disk 54 permits the continued operation ofthev reciprocating bar l26 without damage to the hopper feed in case said disk should become clogged by the nails at any point. The same safety provision takes care of any clogging of the nails at the point where they are transferred from the raceway to the nail driving mechanism, due to the frictional drive provided for theroclrer shaft 117. 4
