T 0 all whom it may concern: I

Be it known that I, HENRY B. GnnnNoUeH,

asubject of the King of Great Britain, re-

sidin at Beverly, in the county of Essex and tate of Massachusetts, have invented certain Improvements in Nail-Transferring Mechanisms, of which the following descrip tion, in connection 'with the accompanying drawings, is a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to mechanisms for transferring nails and is her'ein disclosedin a form adapted for supplying the nailing mechanism'of a heel-attaching machine from a nail-distributing mechanism,

An object of'the invention is to provide novel means to prevent the delivery of more than one charge of nails by the transfer mechanism between successive operations of V the nailing mechanism. A movable work- 'engaging member, as a holder for heels and toplifts, controls in its movement the operation of the transfer mechanism, it preferably governing means which is arranged to limit the movement of saidtransfer mechanism during its nail-transferring travel.

Another object of the invention is to furnish novel means to avoidthe delivery of morethan one charge of nails to the transfer mechanism between successive deliveries to the nailing mechanism. There is shown for this purpose a device arranged to. control the operation from the transfer mechanism of the distributing mechanism which sup plies nails to said transfer. mechanism, said device including "means which delays, until a complete delivery by the transfermecha nism has been made, the operation of the distributing mechanism.

I have chosen in the accompanying drawings to illustrate my inventi'onadapted for use in connection with a heel-attaching machine which may be arranged to drive nails in either of two directions, which is the subject of an application for Letters Patent of BenjaminF. Mayo, filed June 3, 1918, Serial No; 237,951. It is to be understood,

however, that my improved transfer mechanism is not confined in its application to machines ofthis character. Figure 1 of the drawings is a side elevation,parts being broken away, of this invention arranged for delivering nails to a 'machine organized for upward nailing, the

with the transfer mechanism in its delivery position. v

The only essential difference between the two forms ofthe invention is the vertical relation of certain ofthe elements, especially those ofthe' heel and top lift holding mechanism. In Figs; 1 and 2 they are above the heel-attaching mechanism, and in Fig. 3 below it. 1 r p Referring more particularly to Figs- 1 and2 of the drawings, in horizontal ways 260 in a supporting member 256 secured to i a nail block 54 provided with the usual nail receiving openings 262. Pivoted by a spinthe frame22 of a heel-attaching machine is dle 264 on the support to' move across the nail block is a heel and top lift swing plate 266, Jon which" are mounted the adjustable heel fork 268 with its breast gage 270 and the top lift fork and gage'272 311(1274, re; spectively, Fixed to the'spindle carrying the'swingplate and onthe opposite side of j the support is a lever having arms 276 and 278. A spring 280 joins the arm 276 to the support-256, drawing the swing plate about its pivot until it contacts with the yieldable stop 282, such as is customarily provided in connection with such mechanisms and which is arranged tocushion the blow of'the plate against it. The arm 278 has pivoted upon it a latch 284:Wlth its engaging pointarranged to normally contact in the movement 'of'the swing plate with a projection 286 fixed to the adjacent face of the support 256. A spring 288 is seated in a vertical recess in a boss 290' depending from the lever to hold the point of the latch inits raised position,

To lower the pointof the latch to release it from the projection 286, the tail 292 is-struck by a projection 294E carriedby thenailing head 53 when it rises in its nail driving movement. l j Y i On a bracket 296 bolted to theside of the support 256 is mounted a vertical spindle 298, about which turns a loader arm 390 normally in its carrying at its outer extremity a separable loader block 302, in which are perforations 303 arranged in the form in which the nalls I I V are tobe driven into the heel operated upon.

by a latch 312 pivoted at 314 on the loader arm and drawn by a spring 316 between its tail 318 and the arm' into engagementwith a pin 320 on the gate. The loader arm may be swung by its handle 322 to opposite exit 'treine positions, determined by contact of adjusting screws 324 in short arms 326, 328

' with opposite faces of a stop arm 3.30 upon 3 the bracket 296'. When thearm 326 coo'perates with the stop, the loader arm is in such a" position that the openings 303 are alined with the usual nail tubes 332 support edupon a holder 334 fixed to an arm 336 at the top of'thespindle 298. To thetubes 332,

nails are delivered from a suitable distributingmechanism, of which'the tubes and their holder maybe considered a portion. The

. distributing mechanism is tripped to cause itato deliver a charge of nailsto the tubes 332 byia rod 342 guided by an arm 344 secured to the spindle 298. To insure the loader-occupying the desired position when it receives its load of nails, a latch 346 is.

7 pivoted at 348 on the arm300 and is moved by a compression spring 350, situated in a bore on the arm and contacting with the tail of. the latch, so that itspointed end 352 en 'ters a recess of the spindle. When thearm isswung to the left, the inclined face, 354 of theengaging endofthe latch permits it to i arm 328 is in contact with the stop arm 330.

I The parts of the heel and top lift holding bedrawn out of the recess without great resistance, and the loader block passes over the nail block 54 until the openings 262 and 303 are alined, at which time the screw of the and the loading mechanisms being initiallv T as illustrated in Fig. 2, with the block 302 supplied with a load of nails, upon swing- V ing the loader arm toward the delivery posi-' w 9 tion (Fig. 3), the side 355 of an angularend 55 portion 356 of an'arm 358 secured beneath the loader arm s'trikes'a roll 360 upon the arm 276. This turnsthe swing plate 266 and its supporting spindle 264 until the latching projections 284 and 286 engage to holdthe plate withthe heel forkand breast gagein that position with respect to the nail block in which a heel held between them is ready to have the heel seat ofthe shoe upon :the usual jack pressed against it. As the openings 303 in the loader block come into position beneath the block 7 into the openings in the nail block and drive nail block 54. The loader arm is now swung back to its normalposition and a heel and a top lift are placed between the forks and gages of the swing plate. In the travel of the loader mechanism, a face=366 of the arm 308 of thefloader gate, which arm is now in a position substantially at right angles to the latched relation shown in Fig. 2, or as it appears in Fig. 3, comes into contact with a roll 368 mounted upon the rear of the up per face of the support 256. This resets the gate by moving it until the pin 320 is again engaged by the latch 312. A cam member 370 fiXed to the upper side ofthe loader'arm contacts with the rod 342 and trips themechanism of the nail distributor. 338. This takes an appreciable time to operate, so that 901 notuntil the. arm 326 has reached the stop 330 is the load of nails delivered from the tubes 332 to theloader block. When under' the influence of the actuating mechanism,. the driver head rises to project the drivers the nails through the heel into the jacked shoe, the projection 294 on the head contacts with the tail 292 of the swing plate latch-.. The latch is thereby moved out of contact with the projection 286 upon the support, permitting the spring 280 to shift the swing plate to the'position illustrated in Fig. 2, in

which a top lift is brought under the heel attached to the shoe, from which the driven nails. have been left projecting. The portion 3720f the swing plate is now interposed between the driver head and the top lift to serve as a spanker plate.

Were the loader arm to be moved more 1 than once from its nail receiving to its nail delivering position between nailing operations, the first load would be properly introduced intothe openings 262 of the nail block, while the succeeding loads would fall upon theswing plate andsupport and possibly interfere with the action of the machine. 7 Means is provided for positively preventing this plural delivery, consisting of stop arm 374 mountedto turn upon the spindle 264-and drawn against a pin 376 upon the arm 27 6 by a spring 37 8 joining the stop arm with a point uponthe support. This 1 arm 374 has a contact portion 380, which, in the first movement of the loader mechanism in which the swing plate is shifted to bring the heel'holder to the nail block, 'is'so situated that it does not interfere with such movement, the portion 382 of the arm 358 contacting with the edge of the stop arm to turn it about the spindle 264 against the tension of the spring 378. After the swing plate has been turned on its pivot and latched by theelements 28 1 and 286, the portion 380 lies upon the are through which moves the portion 382. Ittherefore catches and holds the arm 358, the contact of the face 355 of the extension with the end of the arm 37 4 preventing the rotation of the'late ter about the spindle.

Difficulty may also be experienced in the use of anail loading mechanism as aresult of making an incomplete movement of the loader arm from its receiving to its delivering position. Since'the load of nails in the block 302 would not be discharged as a result of the contact of the gate latch 312 withethe pin" 500 of the swing plate, the

return of the loader mechanism to it's in-,

itial position would cause the distributing mechanism to drop a second load of nails upon the already filled openings of the loader block, unless there is means for preventing this. Such means is here provided in the actuating member 370 carried by the loader arm to raise the rod3 l2for tripping the distributing mechanism. This actuating member is in the form of a cam block,

shown as curved along the are through.

which "it travels into cooperation with the rod. As the arm swings tothe left in Fig.

'3 in the delivering movement of the loader mechanism, a pivoted contact portion 381'at the lower extremityfof the rod yields so that said rod is not lifted and the distributing mechanism is not affected. When the arm 370 has passed the rod, the portion 381 'jstraightensand upon the return of the loader arm acts as a rigidcontinuation of the rod. As the inclined end 384 of the cam travels beneath the rod during the return,

the latter is raised and is held as long as the extended arcuate portion of the cam is beneath it, thereby tripping the distributer mechanism to causeit to discharge the succeeding load of nails to the loader block whenits openings are alined with tubes 332.

The relation of the cam to the'loader arm is such that it does'not clear the end of the rod 342 in its movement to the left until the loader mechanism has reached its delivery position, in which the loader gate has been released and the load of nails supplied to I the nail block. Consequently for any incomplete movement, in which the nails are re-. tained by the loader mechanism, the porf tion 381 does not straighten, the'rod is not raised and the distributing mechanismcan notdoubly load the block 302.

In the travel'of the loader arm from its I plurality of positions.

' 7 receiving to its delivering position, it is necessary to'c'arry it abovejthe heel holder until the arm has cleared this and is over raises'the arm until the'projection 502 is 'ment of the mechanism during its nail-transjection 502 riding over a corresponding upward projection 504 upon the arm 296. The contact of these projections maintains the proper raised relation until the loader block passes the heel holder, at which time the .70 projection 502 has moved beyond projection 504 and a roll 506 rotatably mounted between lugs beneath the loader arm travels down an incline-of a cam member 508 fixed at the right and near'the rear of the support 7? 256., This brings the loader block gradually to its correct vertical relation to the nail block. lVhen the opposite movement occurs the contact between the roll and incline above its companion projection 504:, so that during the remainder ofthe travel in this direction these projections support the loader mechanism to clear the heel holder.
