ASSEMBLING-MACHINE.

To aZZ to 710m it may concern:

Be it known that I, CHARLES E. CONNER, a citizen of the United States, residing at Auburn, in the county of Androscoggin and State of Maine, have invented certain Improvements V in AssemblingMacliines, of which the following description, in connec tion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figuresi The presentinVBIltiOn relatesto improvements in machines for assembling shoe parts and isherein set forth with particular reference to its utility in assemblingand securing counters such as previously molded counters in the manufacture of turn shoes made according to the method disclosed in Patent No. 1,302,994, granted u on an application filed in the name of J. C Thisse 1, although the invention is not limited to such use.

According to this method of incorporating a counter in a turn shoe a previously molded counter is attached to the heel portion of the sole after the shoe upper has been secured to the sole inside out in the well-known manner of making turn shoes but prior to turning the shoe right side out. It is of especial importance in practising this method properly to locate the counter in an upright or final position relatively to the sole with.

particular reference to the interior dimensions of the shoe after the shoe is turned to. obtain a shoe of the desired predetermined size and to insure the second last fitting the Shoe snugly. Moreover, it is essential that the counter should be permanently and strongly attached in the position it is finally to occupy in the finished shoe in spite of any handling whichwould be liable to displace the counter A further difficulty arises from the heel seat nailing operation which hasheretofore been performed after the shoe is turned since the heel seat nails unless carefully inserted are liable to interfore with subsequent heel attaching andfinishing operations on the shoe and also the heel seat nailing operation necessitates an additional handling of the shoe.

The invention has for its objects to provide for accurately, efficiently and economically assembling molded counters and turn shoe parts and to insure that the counterswillbe so incorporated in the shoe that they Specification of Letters Patent. Patented June 28 1921 Application filed September 10, 1918 Serial No. 253,411.

will be permanently in the correct relation to the other parts and especially in correct lengthwise relation to the shoe.

- With the above and other objects in view the illustrated machine, which constitutes a preferred embodiment of the invention, comprises a novel organization of means for supporting the various shoe parts including tion relatively to the heel seat portion of the sole to which the counter is to be attached. In. the operation of the machine illustrated, the shoe support carrying the shoe and the counter support carrying the counter are moved relatively into a position to seat the counter in its final position on the heel seat of the sole and then fastenings are inserted by the machine permanently to attach the counter in the said position to the sole of the shoe.

In the illustrated machinerelatively adjustable counter and sole edge gages are provided respectively for holding the counter and for positioning the rear of the sole in proper relation to the counter according to the particular style and size of shoe being made.

As herein illustrated and in accordance with a further feature of the invention, the fastening inserting mechanism is preferably constructedand arranged to insert a plurality of fasteners in a single operation to secure the flange, of the molded counter to the underlying heel seat portion of the sole. By attaching the counter to the sole in a single operation not only is the counter more strongly attached in its final position in the shoe, but there is less. liability of the counter being displaced as through careless- .ness in subsequent handlings of the shoe.

Other objects and features of the invention will appear from the following description when considered in connection with the accompanying drawings which illustrate a preferred embodiment 0f the invention tion of which a preferred form of my im-- provements has been embodied, parts of the construction being shown in section and other parts being broken away for clearness of illustration; r

In the accompanying drawings the inven tion is illustrated as embodied in a heel attaching machine of the type shown in United StatesIatentNo. 446,885, granted Feb. 24, 1891 on an'application of Joseph H. Pope to which reference may be had for a more complete description of the machine con-. p

jtheir outer ends curved slightly. inwardly as struction not herein disclosed in detail.

The present invention however, is not limited in its application to that or any other particular type of machine.

The machine comprises a frame 2 provided with a stationary cross bar 4 in which fected. in any suitable manner, for example,y

through a lower cross head connected with an'eccentrlc on. the driving shaft of the ma chine as shown in the patent to Pope above referred to. In the lowerpart of the frame 2 vertical guideways are provided for ack carriage support and a superimposed jack carrlage 16. 'The latter is provided with" horizontal ways 17 for the jack 18 which.

carries theshoe to be operated upon, the ack comprislng a vertically adjustable heel post 19 carrying a last pin 20 and an adjust able toe post 21 to support the toe of. the

shoe. The jack carriage '16 is elevated to bring the heel seat portion of the shoe in work clamping relation to the nail inserting mechanism by suitable power operated. As; shown in the patent to Pope above referred mechanism in the base of the machine.

to, a'nail loader 22isprovided to furnish the nail block with the required number of nails to be driven, these nails being preferably of the headed type to insure the holding effect of the nails.

Centrally mounted on the under surface of the stationary cross bar 4 by means of the bolt 24 and dowel pins 26 is a'block 28 which serves to support a shoe counter '30 v for attachment in upright position on the heel seat of the shoe 32. This block 28 is shaped to enter the smallest size of counter to be used so that it will not be found necessarv to substitute various sizes of counter supporting blocks when'operating upon dif-' ferent sizes'of shoes and it has its bottom surface slightly concaved to correspond to the convexed heel seat surface of the. shoe,

thus. insuring a proper seating and clamping of the inturned flange of the counteron the heel seat. Drlver guiding passages '6 are uation of the driver passages 6 in'the cross block 28 and nearits forward edges are a shown'in Fig. 3 so as to grip the counter. and cause it better to hug the counter block. The screw 40 which has heads42 at either end provides for simultaneous lateral adjustment of the clips36 to accommodate different sizes of counters. on the block, a Set screw 44 being provided to lock the screw in any of its adjusted positions. Extending downwardly from the under side of the crossbar'4 to which it is secured by the screw 48 and against the rear surface of the block 28 is another sorin clio 50 which 006 erv i a l ates withthe clips '36 correc tly to position the counter on; the counter supporting block and hold it against displacement. The driver guiding passages 6 in the cross bar 4 and in the counter block 28 arelocated as. near s practical to theouter wall of the block 28in'a' U-shaped design to insurethe nails. being driven through the inturned flange of the counter and adjacent to its inner wall.

, Also, the drivers 8 a'nddriver passages 6 are so arranged that they do not insert fastenlngs forwardly of substantially the heel.

breast line of the shoe to bev operated upon; otherwise, in turn shoes the clenched ends of the nails would appear on the finished surface of the sole.

The-shoe and the counter are accurately iio positioned relatively to each other by means i of a shoe engaging gage '52 and a counter engaging gage 54 both of which are mounted for vertical adjustment and for a lineited yielding movementiso that they will accompany the shoe in its slight downward displacement when subject to pressure. For this purpose arod 56, the upper end of which carries the gages 52, 54, is slidingly mounted at its lower end in a bracket 58 and is normally maintained in an elevated position by a compression spring 60 which encircles the end of the rod as shown in Fig. 1. Near its upper 'end the rod 56 slides in an angle piece 62 having a threaded shank 63 which extends through the forks of a bracket 64 on the machine frame; An adjusting nut 65 on the shank 63 serves to determine the adjusted position of the shoe or sole gage and, therefore,the position of the shoe longitudinally of the counter. This gage is of considerable importance in the use of the machine and in the performance of the steps attendant upon the attachment of the counter to theshoe, since the location ofthe shoe relatively to the counter when attached redetermines the interior dimensions or nal size of the shoe. and unless such accuracy in relatively locating the shoe and counter is insured subsequent operations on the shoe are impaired and a shoe of thewrong size is produced. The counter gage 54 is located immediately above the sole gage 52 and is mounted for adjustment relatively to the sole gage and in the direction but independently of the sole gage adjustment by means of a set nut 66 on the end of the rod 56, which projects through a slot in the counter gage. The forward'end or counter engaging surface 67 of the gage 54 is inclined backwardly as shown in Fig. 2 so as to force the vertical inner wall of the counter, particularly at its junction with the inturned flange portion, against the lower edge of the counter supporting block.

In the use of the invention with the machine herein illustrated, the shoe upper is first attached to the sole while inside out as described in the above mentioned patent to Thissell. The ack l8 is next pulled outwardly in the ways 17 of thejack carriage and the shoe 32 on the last is placed on the heel post 19 with its toe resting on the toe post 21, the jack being then adjusted for height and for the length'of the shoe in question. The jack and the shoe are then pushed rearwardly into the machine until the rearend of thesole of the shoe engages the sole gage 52 which is then adjusted by means of the adjusting screw 65 to locate the heel seat of the shoe in predetermined longitudinal relation to the counter 30.

In the next step of the process the previously molded counter of the proper size and shape to fit the shoe which is being made is placed over the countersupporting block 28, the side walls of thercounter being sprung under the side clips 36 which, by

reason of their inwardly olllVfid lower ends vided on t e lastengage the counter near its lower edge and hold it in position on the block. When counters are being used'which are not held iii some way in final position against spreading; for example, a half molded counter, the side clips also serve to maintain the counter in the desired shape on the block, the spread of the counter being predetermined by the lateral adjustment of the clips through the adjusting screws 40. The rear upper edge of the counter is also definitely located on the block by the clip 50 and to insure the firm seating of the counter with its inturned flange overlying the bottom of the block and its inner wall in contact with the wall of the block the inclined surface 67 of the counter gage 54 is forced against the lower edge of the. counter as shown in Fig. 2. Thus the counter is firmly supported in predetermined position relatively to the shoe and the inturned flange of the counter is in position on the bottom of the block to receive the nails inserted through the driver passages 6. It will be obvious to those skilled in the art that with the Thissell practice of incorporating molded counters in turn shoes the accurate location of the counter upon the heel seat of the sole is of especial importance since it determines the interior dimensions of the shoe after it is turned right side out and therefore the'final size of the shoe. By providingmechanical 'means for supporting the counter of the shoe in a predetermined 'position'and for supporting the shoe in assembled relation to the counter, including provision for effecting a fine adjustment of the shoe in the d1- rection of its length, as in the illustrated machine, the two shoeparts may be permanently associatedewith absolute accuracy and uniformity. h

After the shoe and the counter have been properlypositioned, the machineis started and the jack 18 is elevated indirect vert1-' cal "alinement with the counter supporting block 28 whereupon the counter is seated upon the heel seat of the shoe with increased and positive pressure. During this relative movement of the shoe and the. counter the gages 50 and 52 are carried with them, thus preventing their displacement and then as the shoe and counter settle under the pressure, the" gages yield. "While the shoe '15 thus held under pressure the attaching nails which are preferably headed are deposited by the loader'22 in the driver passages 6 and driven by the drivers 8. As previously explained the driver passages are located near the outer wall of the counter supporting block and consequently they pass through the inturned flange of the. counter and the margin of'the sole of the shoe being clenched upon the usual iron bottom pro- The ack is then lowered which removes the counter from its support and pulled forward so that the shoe may be removed. c a

The method which has been disclosed above is not claimed herein but in application Serial No. 343,365, which is a d vision of this application. c 7
