HEEL NAILING AND TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 377,577, dated February 7, 1888.

Application filed November 10, 1887. Serial No. 254,746. (No model.)

To all whom, it 11mg concern.-

Beit known that I, FREEBoRN F. RAYMOND, 2d, of Newton, in-the county of Middlesex and State of Massachusetts, a citizen of the United Sta'te's,have invented anew and useful Improvement in Heel Nailing and Trimming Machines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described'in various patents heretofore granted me in my application for Letters Patent filed April 16, 1887, and in the application of O. 0. Small, filed April 19, 1887; and it comprises an automatic heel nailing or attaching machine having a number of jacks adapted to be brought successively into operative position in relation to the heel-attaching devices.

It further relates to the combination of a series or number of jacks mounted upon a common support and adapted to be rotated or turned with said support into operative positionwith the heel-blank-attaching devices and said attaching devices.

It further relates to the'organizat-ion, in an automatic heelattaching machine,'of a numher or series ofjacks mounted upon a common support and adapted to be rotated in relation to the heel-attaching devices, with said heelattaching devices, comprising mechanism for automatically feeding the heel blank and,

.when atop lift is separately fed, the top lift into position for attachment, an automatic nail-supplying mechanism, and a gang or group of awls and gang or group of drivers,

with or without a heel-breasting device, also automatically brought into position and operated.

It further relates to a heel-nailing machine having a number or series of jacks each having a movable post, spindle, or support, said movable posts, spindles, or supports and a common head carrying the jacks and'adapted to move the spindles or posts of the respective jacks into operative position with the attach ing devices.

It further relates to the organization and combination, in a heel-attaching machine, of two or more jacks mounted upon a common support adapted to be moved to bring the jacks into position, the heel-attaching devices, and heel-trimming mechanism.

It further relates to the combination, with heel trimming devices, of a series of jacks mounted upon a common support and adapted to be moved to present heels in sucoessiveorder tothe heel-trimming mechanism. 7

It further relates to various features of organization and construction, all of which will hereinafter be explained.

' In the drawings, Figure 1 is a view in front elevation of a machine containing the features of my invention. Fig. 2 is a View thereof in vertical section. Fig. 3 is a view in plan of the heel-trimming devices. Fig. 4 is a view Fig. 5 is a view a Ais the nail-carrier, which is automatically moved into and out of position by the cam a upon the vertical shaft a, to carry nails from the automatic nail-supplying devices (not shown) to the templet.

B is areciprocating head. I

B is a rotary-head carried by the reciprocating head, and'having the arm I) supporting a block having a gang or group of awls, b, an arm, if, having a block carrying a gang or group of drivers, If, an'arm, b, and an arm, b carrying the heel-breasting knife I). This head B" is rotated,.preferably, by means'described in said application of O. 0. Small.

' C is the heel-blank carrier, and Ois the toplift carrier.

0 is the stack of heel-blanks; O, a stack of top lifts; c, the heel-blank transferrer, and'c' the top lift transferred. The heel-blank and top-lift transferrers are operated substantially as described in said Small application.-

The jacks D are mounted upon the head or support D.

This head or support has horiioo zontal guideways cl for each jack, and it is also provided with a central hole, d, whichj receives the horizontal post or stud d, with which the head D is adapted to be turned. This post or stud d is supported by and has bearings in the frame or bracket D". (See Figs. 1 and 2.) Each jack D has a verticallymovable post, spindle, or support, d which supports the last or work-support (1*, and each jack is adapted to be moved horizontally upon the head D when it has been turned or moved to an upright position as represented in Fig. 1, with the last or jack-support beneath the templet A and the spindle or post (I in line with the toggle-head E. The base of the jack in this event is supported by the head D and by the table d which has ways d in extensions or ways cl of the head D. The head D and the table d are not required to take any strain. They simply act to support the jack, the strain of the operation of the machine coming upon the toggle-head E and the templet A. The head D is locked automatically in position, to bring its guideway d in line with the guideway d, by means of the spring registering-pin (l (See Fig. 2.) The toggle-head E is made vertically movable by means of the cam 6 upon the vertical shaft a, which has a cam-groove, e". The lever e is pivoted at e, and has a cam-pin that enters the cam-groove e, the toggle e comprising the links 6 e, the first of which is pivoted to the stationary support e at its lower end, and the second of which is connected at its upper end with the slide-head e", and the links of the toggle are connected with an arm of the lever e by means of the link 6 The slide-head c has a bearingin the bracket e, and the toggle-head E is vertically adjustable on the slide head by screwing thereon. (See Fig. 2.)

This construction or organization of jacks and attaching devices allows a number of jacks to be moved successively into operative position and enables a saving in time to be effected, which is of very considerable importance in the operation of themachine, as it permits the operator to utilize the time which is otherwise of no account in removing the finished shoe from a jack moved out of position and the placing of an unheeled shoe upon a jack about to be moved into position; or, if an assistant be employed, it enables one to remove the work and the other to place it, and to thus increase the capacity of the machine very considerably.

I would say that it is not essential, so far as the material features of the invention are concerned, that each jack be movable horizontally upon the head D, as the head itself may be placed in linewith the templet and provided with a vertical movement.

The trimming apparatus Gis represented as placed below the templet A and in a line therewith, and so that it may operate to trim or shave an attached heel simultaneously with the attaching of a heel to another boot or shoe by the heel-attaching devices above specified.

While I have shown the trimming mechanism as placed below the heel-attaching devices, I would say that I do not confine myself to this location, as it may be placed upon one side thereof, in which event support for the jacks is organized to turn upon a horizontal plane. I prefer, however, when a jack rotating on a vertical plane is used to locate it be tween the jack and the nailing device, as indicated, as it makes a more compact construction, and because the skivings and chips from trimming are made below the principal working parts of the machine and cannot get into them, to interfere with their ready operation, and because it is more out of the way.

The trimming devices which I have represented are the well-known McKay devices described in various patents granted to Charles H. Glidden and used upon the heel-attaching machine known as the McKay heel-attaching machine, and it is unnecessary to more than briefly say that they comprise a knife, G, which is carried by a block, 9, which is caused to be moved about the heel, and is guided in part by camtracks and in part by suitableforms or guides. The operalivemechanism differs from the McKay in that the sprocket-wheel g for rotating the k nife-carry ing block is revolved by means of a larger sprocket-wheel, g, and by the chain G, which connects the two sprocket wheels. The sprocket-wheel g is arranged upon a pivotor post, 9*, and has a forward-and-back movement communicated to it by means of the cam 9 upon the vertical shaft a. This cam has a cam-groove, 9 which is connected with the sprocket-wheely by means of a lever, 9 which is pivoted at y and which is connected by a link, 9", with the cam-groove, and by thelink 9 with the sprocket-wheel gfland a partial rotation forward and back of this sprocket-wheel 9 causes the knife-blockto be rotated very nearly an entire revolution about the heel of the boot or shoe and to be returned to its original position.

There is attached to each jack, spindle, or post a boot or shoe holding and protecting device,H,which is movable there\vith,and which is similar in construction to that described in the said patents and found in the said Me- Kay machine. I would say, however, that, so far as the broad features of this invention are concerned, I do not confine myself to the special mechanism herein described for tri mmin the heel.

The sprocket -wheel 9 and the cam and knife-block are supported upon a spindle, g,

ICC

which has a bearing in the bracket g, (see Figs. 2 and 4,) and it extends below said bracket and its end rests upon the block 9, which is carried in the front end of the lever g, and in relation to which it has a vertical movement in opposition to the spring g, the front end of the lever having a hole of sufficient size to receive the block g" and spring The lever g is pivoted at 9", and is operated by the cam 9" upon the shaft a,having a cam-groove, g, and its office is to press or move the lower heel-trimming form, 9, and

the knife-block upward vertically against or in relation to the heel of a boot:or shoe upon the starting of the machine, and to maintain them in that position during the trimming of the heel.

The front end of the lever always has the same extent of movement, and for this reason I make the connection between it and the spindle g a yielding one,in order that the heelform and knife-block maybe always moved to any desired relation to the heel-blank, regardless of its height, the block 9 yielding with the spring g to allow this to take place.

The spindle g of course is made square, and fitsa square hole in the bracket 9, to preventits being turned.

In operation the operator preferably stands at the right side of the machine, the boot or shoe to be heeled and trimmed is mounted upon the last or work-support, the first or second last or work-support to the right of the templet facingthe machine. The last or worksupport isthen operated to move or bring the boot or shoe into position beneath the templte A, and the machine is then set in operation. The jack-spindle of the last or work-support, which is in position, is then moved upward, compressing the heel-blank, which has previously been moved into operative position beneath the templet, solidly against the same, the heel-blank is perforated, the attachingnails fed and driven, the top lift fed, and the heel breasted automatically, as described in the Small machine. Meanwhile the operator has been placing another boot or shoe upon the next last or work-support in order, and upon the completion of the attaching and breasting of the heel of the first boot or shoe the jack-support is turned to bring the second boot or shoe into position, and the machine is operated as before.

If the trimming apparatus be not used, then the heeled boot or shoe may be removed from the last or work-support by a boystanding upon the left of the templet; or the jack-support may be rotated and shoes presented in successive order to the nailing devices until the shoe first nailed reaches the operator, when he then removes the same and substitutes another, and continues to operate in this manner. Y

When the trimming mechanism is employed,

the heeled boots or shoes are advanced in successive order until they .reach the trimming mechanism, and after the first one in order has reached itthe operation of the machine is as follows:

Upon the starting of the machine a heel is attached to one boot or shoe, while the trimming mechanism is caused to be automatically operated to simultaneously trim the heel previously, attached to another boot or shoe. The rotation or movement of the jack-support having simultaneously moved into operative position, one boot or shoe beneath the heelattaching devices, and another boot or shoe into operative position in relation to the heeltrimming devices, it is desirable that the heel should be under some degree of compression 7 during the trimming operation, although, as a I would say that I do not confine the invention to the employment of ajack-support movable upon a vertical plane, because it may be movable upon a horizontal plane, if desired; but I prefer the vertical plane, because it has some advantages which the organization employing a jack-support movable upon a horizontal plane wouldnot possess.

The advantages of the invention arise, first, from the rapidity with which the work may be presented and removed from the heel-attaching device; second, from the saving in time which is obtained by the simultaneous attaching of one heel and the trimming of another bythe same mechanism; and, third, by the organization of themachine, which disassociates the heel-trimming mechanism from the nailing devicesto such an extent that the construction is simplified and the partsof the heel-trimming devices made more accessible, and the place of trimming removed from the place of nailing, so that the scraps, dust, and skivings cannot interfere with or check the nailing devices and the fine organization of the nailing mechanism permitted.

I would say in this connection that I am aware that it'is not new to combine in one organization a heel nailing and trimming mechanism of a peculiar organization, which attaches what is known as a loaded heel and then trims it as successive operations. not aware, however, that there has been any heel attaching and trimming machine organized which involves the automatic presentation of the heel-blank and top lift to attaching devices and the useof attachiugdevices which involve the compression of the heelblank upon the soles of the boot or shoe, the prick- I am.

IIO

ing of the holes therein after the heel-blank has been so compressed and the driving of the attaching-nails; and I would further call attention to the factthat as the attaching of one heel and the trimming of another attached heel arev simultaneous operations, a saving in time is accomplished over the operation of a .ma-

chine which first attaches loaded heel-blanks and top lifts and then trims the same heel.

Having thus fully described my invention,
