HEEL-MACHINE.

SPECIFICATION forming part of Letters Patent No. 537,818, dated April 23, 1895.

Application led December 21, 1894;. Serial No. 532|538. (No model.)

To @ZZ whom it may concern:

i Be it known that I, EDWARD F. OoNNoRs, a cltizen of the United States, and a resident of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Heel-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates generally to improvements in machines of the above class and more particularly to improvements in machines for cutting and assembling decked heel blanks. Y

Decked heel blanks as the term is commonly used in the trade consists of a series of lower lifts of substantially uniform size to which are nailed a series of upper lifts of larger size commonly called the deck. The deck projects around the curved portion of the blank but is commonly even with the rest of the blank on the breast.

My invention consists of improvements in the form and arrangement of the lower lift4 die and deck die and of the mechanism for regulating the thickness of the assembled deck and bottom blank and expelling the linished blank from the dies, as hereinafter more specifically set forth and claimed.

My invention further consists of a device whereby the deck die may be removed while the lifts are being cut bythe lower lift die, and adjusted in position and locked to cut and assemble the deck lifts.

My invention further consists of a device for removing the finished blank from the dies, and of the devices and combination ot' devices hereinafter more specifically set forth and claimed.

As deck heel blanks have been heretofore constructed the lower lifts are cut andl assembled in a suitable die. They are then nailed together and removed from the die. The bottom blank thus assembled is then placed in the deck die (so called) having been first placed in a case or false deck which fills the space between the walls of the deck die and the bottom blank, and holds the same in position 4in the deck die. The deck lifts are then cut and assembled in the deck die and nailed to the bottom blank.

The object of my invention is to provide a device whereby a decked heel blank may be rapidly and conveniently cut and assembled without removing any portion thereof from the dies.

My invention is illustrated by the drawings herewith submitted, in which Figure lis a side elevation. Fig. 2 is a plan view. Fig. 3 is a section on line X X, Fig. 2. Fig. t is a section on line Y Y, Fig. 2. Fig.5 is a front view of the dies showing locking mechanism for deck die.

Similar letters and figures of reference refer to similar parts throughout the several views;

Referring to the drawings A represents a frame suitable to support the working parts of the machine. Y

D represents the bottom lift die by means of which the lifts of the bottom blank are cut and assembled, and D represents the deck die7 by means of Which the deck lifts are cut and assembled.

The dies D and D are vertically disposed with reference to each other, the die D being smaller than the die Dand placed within its periphery or a horizontal projection thereof.

T represents the supporting table which forms the working bottom of the die D upon which the bottom lifts are assembled. The upper edge of each of the diesD and lD constitutes its cutting edge and their relative vertical position is adjustable. The supporting table T is also vertically adjustable in the die D. The vertical adjustment of the dies D and D' determines the thickness of the deck and the vertical adjustment of the table T in the die D determines the thickness of the bottom blank. The die D is arranged to be removed from its position over die D,I to allow the bottom lifts to be cut and assembled therein, and to be readjusted and locked in position for the forming of the deck.

I will now describe in detail the form and arrangement of the dies and auxiliary mechanism shown in the drawings, but before doing so I wish to say that I do not consider my invention limited to the specific devices hereinafter described as many modifications thereof will readily suggest themselves to one skilled in the art involving no departure from the essential nature of my invention.

Mounted in suitable bearings in the frame A is a standard 4, free to reciprocate vertically in said bearings for the purposes here-V IOO inafter set forth. Mounted upon the standard 4 is the bottom lift die D adjustably secured thereon, conveniently by means of the setscrews d, d, which are supported by the ears e, c which project from the standard 4. Surrounding the die D is the deck die D which is suitably mounted upon the frame A In the specific construction shown, the die D' is connected by hinge 2 (preferably at the oenter of its curved portion) to abracket 1. The bracket 1 consists of a vertical portion a which supports the die D, forming substantially a continuation of its wall, and a horizontal portion or plate b which is secured to the frame A conveniently by the bolts c, c, ttc. To keep the breasts of the dies D and D in substantially the same vertical plane for the purposes hereinafter described, I find it convenient to provide the die D with a horizontal adjustment in the direction of the breast. This I secure by slightly elongating the bolt holes o, o, ttc., in the bracket 1 (as indicated by dotted lines Fig. 2) so that the bracket 1 and die D thereon can be moved slightly toward or away from the breast of die D. The bracket 1 is provided with the slots 72, h which receive'the ears @,e, and permit the raising and lowering of the same with the standard 4.

The die D may be turned back on the hinge 2 to be out of the Way while the bottom lifts are being cut by the die D, and a suitable rest 11 may be conveniently provided to support the die D when turned back for the purpose above set forth.

When in position above the die D to cutand assemble the deck, the die D may be conveniently locked in position by the following mechanism:

Projecting from the die D are the fianges 12, 12 which are engaged by the shoulders 13, 13 on the levers 14, 14 which are pivoted at 15, 15 to the bracket 1. Suitably placed springs (not shown) acting on the levers 14, 14, normally hold thev shoulders 13, 13 in engagement with the flanges 12,12, or the same result may be secured by the weight of levers 14, 14. The levers 14, 14 extend over the front of the machine and are bent to approximate their free ends, which may conveniently be provided with the thumb pieces 16, 16 by means of which they may be turned inwardly and the flange 12 released from the shoulder 13.

As already stated the standard 4 is free to reciprocate in suitable' bearings in frame A and to effect such reciprocat'ion l provide the following mechanism:

In a suitable guide way in the frame A is mounted a longitudinally beveled bar P, the upper and beveled surface of which forms an inclined plane upon which rests the lower end of the standard 4. The bar P is free to reciprocate along its guide way in frame A and may be set in any desired position along the same by means of the threaded bolt 6 which may be conveniently operated by the wheel 9', and is provided with suitable bearings in frame A.

The above described arrangement is such that as the bar P is reciprocated along its ways in the frame A by the rotation of wheel 9 the inclined face thereof acts upon the lower end of the standard4 to raise or lower said standard andthe die D mounted thereon, and, since the die D is secured to the frame A,to effect the vertical adjustment of the die D with relation to the die D.

As the distance from the top of the die D to top of die D determines the thickness of the deck, this result is secured by the above described adjustment.

As hereinbefore stated the vertical adjustment of table T determines the thickness of the bottom blank and the same may be conveniently accomplished as follows: The table T is mountedaipon a rod?a free to reciprocate vertically in a suitable guide way in the standard 4. To a groove 17 in the bar P is fitted a longitudinally beveled bar P the under side of which forms an inclined plane correspondingin inclination with theinclined face of bar P. The bar P is free to reciprocate along. the groove 17 and may be conveniently actuated by a threaded bolt 10 rotated by a wheel 31. The bearings of the bolt 13 are secured to the bar P. In the standard 4 is a slot 18 which receives the bar P as the oar P is slid along under the same by the rot tation of the wheel 9. The rod 7^ rests upon the upper side of the bar P which is substantially horizontal. By the arrangement above described, when the bar P is reciprocated to raise or lower the die D, the rod r rests upon the horizontal side of the bar P and its vertical position and the vertical position of the table 'l mounted thereon remain unchanged, but when the die D has been brought into the required position, the table T may be adjusted to the required heightin the die D by moving the bar P along the groove 17 by means of the thumb wheel 3l.

In the rod r is formed a socket 2O in which works a ball 21, carried by the lever 22 pivoted at 23 to one of the ears e upon the standard 4. The free end of lever 22 projects from the frame A in convenient position to be struck by a hammer or other convenient instrument. The above described arrangement is such that after the decked blank is assembled and nailed or otherwise suitably united, by striking a sharp blow on the lever 22, the finished blank is thrown out of the dies D and D.

As shown in Pig. 4 the cutting edge of breast of die D is in substantially the same vertical plane as the cutting edge of the breast of die D and for this arrangemement a slot u is formed in the breast of die D into which the breast wall of die D extends.

In the operation of rnyinvention the die D is first adjusted in the deck die D to make a deck IOC IOS

of the required thickness and the deck die D then thrown back onto the rest ll. The table T is then adjusted in the die D to form the bottom blank of required thickness and the lifts are cnt and assembled in the die D in the usual manner. When the die D is full the die D is closed over the same and locked as hereinbefore described and the deck lifts are cut and assembled therein in the usual man ner, the bottom deck lift resting upon the full die D. When the deck die D is full a nail (or nails) is driven through the deck into the bottom blank to hold the finished blank together, and by tapping on the lever 22 the finished blank is thrown out of the dies D and D.

Having thus described my invention and its inode ot operation, I claim as novel and desire to secure by Letters Patentl. In a heel machine the combination of the deck die and bottom lift die vertically disposed with reference to each other, mechanism for adjusting the relative vertical position of said dies, a supporting table in the bottom lift die, and a vertically reciprocating rod supporting said table, mechanism for reciprocating said rod adapted to retain it at the required height to regulate the thickness of the bottom blank, and independent lnechanism for reciprocating said rod to expel the iinished blank, substantially as described.
