To alljwhom it may concern: I

Be it-known that L-Enns'ros WooDwARD,

Stateof Massachusetts, have invented a new.-

and useful Improvement in h'lachines for Loading I in'g is'a specification. I

of which nails are partly driven into a pile of heel lifts in order'to form a heel blank-ready to be attached by the same nails to the shoe, and it consists chiefly in certain mechanism to be hereinafter described, by means of which the heel will 'be fed after every nail driving;

operation, but will not be fed unless a nail has been driven, the nail acting to control the heel feed; and my invention also consistsin means for stopping the machine'when a prope number of nails have been driven. 1

I preferto'embody .my invention as an attachment to-an ordinary power press. I have shown in the drawings the plunger of such a press and prefer to combine with ita clutch mechanism like that described in Letters Patent granted to James A. Horton, No. 260,394, dated July 4, 1882, to which patent Ire't'er for. adescrip'tion of the clutch mechanism, only the connections therewith being referred toherein and shown in the drawings.'

Fig. 3 is a detail section taken on' linefi, 3 of Fig. 4, and Fig. 4 is a plan showing the heel feeding mechanism, t'he driver and driver connections being removed. 'Fig. 5 is a plan partly in section showin g the feed controlling mechanism and Fignfiis a section on line 6, (tot Fig. 5.

The heel feed consists of a pawl and ratchet mechanism'which will now be described.

H is a toothed wheel-mounted on a studin the table A and adapted, to engage with each of the feed pins f on this heel plate F in turn. Fast to the under side of this toothed wheel is; a ratchet wheel J operated by a. pawl J carried byalever j. This lever j is f ulcrumed on a slide L running in ways in the table A mal position, will engage with the ratchet J and turn it and the Wheel 1-1. The. engagement of this wheel with oneot the pins f" on the bottomiot'the heel plate, will cause. the heel plate to be fed.

The heel feed is'controlled by mechanism preferably of the kind to be described, which allows a feeding operation to take place when ever a nail has been driven, and prevents In its forward movement, the pawl J' ,i f in its nor-- toward the driving: mechanism by m'eahs ot' a the feeding ot the heel when a'nail has not been. driven. The essentials of this mecha n ism as it now seems to me, are a controlling part adapted to move across the line of motion of the nail driver constructed to have its motion interrupted, if a nail has been driven,

IOO

and to -niove freely across that line if a nail has not been driven; and also a feed mechanism adapted to feed the heel carrier, but so related to the controller that it will be rendered inoperative or not, according to the distance which the controller has moved.

N is a stationary nailfeedway which carries the necessary mechanism not shown, for separating the nail in the raceway n and I0 feeding it to the driver. Such mechanism is well known and therefore is not further described, as it forms no part of this invention, nor is any peculiarform of nail feeding mechanism. necessary to a proper embodiment of thisinvention. This nail feedway carries on its under side a reciprocating slide M. The front end of this slide M is adapted to clear the heel (see Figs. 1 aud o) and the forwardmovement of this slide is sufiicient in extent to cross the line of motion of the driver, and thus pass over the place where a nail should be, if no nail has been driven, this part being the controller above referred to. This slide M is connected by a pin 7c to the bell crank K, the front end of which is thrown forward by means of the spring 70 so that the tendency of the slide M is, when nncontrolled,to move forward in the direction of or across the line of motion of the driver. This slide M is witho drawn by means of the crank lever P the lower toe of which strikes against a pin at projecting from the side of the controller M. The lever P has a slotted portion 19' in which moves the pin 1) carried by the bell crank le- 5 ver P which gets its motion from the plunger 0 by means of the link P The bell crank lever K has a pin j projecting from its under surface acting as a cam surface in connection with a corresponding pin j mounted on the 40. upper side of the pawl lever J, and the location of these parts is such that if the controlling slide M moves across the line of motion of the driver, the pin 3' will be so located that as the pin j is carried forward by the 5 movement of the slide L, it will pass in rear of .the pin j and consequently withdraw the pawl J from the ratchet J and feeding mechanism, whereas if the slide M, in its forward movement, strikes a driven nail, it will so 10- cate the pin 7' that when the ping" is carried forward by the pawl slide. L, it will be moved in front of the pin j and the pawl will be caused to engage the ratchet and turn the ratchet wheel and feed wheel ll, thus feeding the heel.

n, is the nail driveway which is moved by the frontend of the leverP and slides in ways in the front of the nail feedway. It carries the pinchcrs shown in dotted lines in Fig. 2

50 and adapted to hold the nail straight when the driver first starts it.

' The driver above described and above referred to, is arranged to drive nails only 'dicated by the arrow in Fig. 4.

upper, portion or head of the nail, projects above the upper surface of the top lift as shown in the drawings.

The operation of my machine is as follows:- The parts are so timed that as the plunger rises, the slide L moves forward to feed the ratchet. Before=howevei:, the pin j has come within reach of the pinj the slide M has been released by the bell crank P so that the spring k will throw it forward. If a nail has been driven, it will stop when it reaches the head of the nail Q and the pinj will pass in front of the pin 3' so that the pawl and ratchet will engage and the ratchet will be turned, tnrningthe toothed wheel ll and feeding the heel plate; whereas ifno nail has been driven, the slide M will pass from the point where the nail should have been driven and so place the pin 3' that the pin j will pass behind it and prevent contact between the pawl J and the ratchet J. \Vhen the slide M has finished its forward movement, a nail having been placed between the pinchers in the nail feedway, the plunger begins its descent. The slide L is removed so that the slide M will be free to move back and the nail beingheld in place against the top of the heel lift by the pinchers, another driving operation takes place. It will be seen that as many nails will be driven in the heel as there are feeding pinsf', and it will also be seen that the heel plate will be turned so long as a pinj lies in a depression in the wheel II, the feeding operation being in the direction in- Vhen the feeding operation is finished so that the last pin, which I have marked f comes between the teeth and the wheel 'II, a corner R of the heel plate will come in contact with the pin 3 on the under side of the lever S and trip this lever so that the clutch operating mechanism T is released and the machine will stop automatically. The lever S is fulcrumed at Sf and -is provided with a handle S so that the lever may be operated by hand to stop the machine.

It is obvious that my invention may be car ried out in a variety of ways, the essentials beinga controiler and a feed mechanism capa bio of disengagement in the manner above described, the controller operating across the line of motion of the driver and hence operated by engagement with a driven nail to cause the feeding operation. I

By means of this invention, it is possible for one operator to tend a number of ma chines, his work being to place the pile of lifts in 'position, start up the machine and leave it. At the proper times the feeding of the heel will take place and when the last nail has been driven, the stop mechanismf s will cause the machine to stop, so that the machine is perfectly automatic, so far as driving the nailsand stopping when the work has been done is concerned.
