HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 316;828, dated April 28, 1885.

Application tiled January` 24, 1885. (No model.)

To all whom it may concern:

Be it known that l, FREEBORN F. RAY- MOND, 2d, of Newton, in the county of MiddleseX and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel-Nailing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specilication, in explaining its nature.

The invention relates to a heel nailing or attaching machine, and comprises various features of construction whereby the boots or shoes are .fed continuously to the heel-attaching devices, and the heel-blank first pricked and then moved with the jack to the attaching devices, all of which will hereinafter be more fully described, together with the various details of construction.

Referring to the drawings, Figure l is a vertical section of a machine containing my improvement. Fig. 2 is afront elevation of the central upper partsof the machine. Fig. 3 is a vertical central section to illustrate various stops for controlling the movement of the templet or pressure plate, hereinafter referred to. Fig. 4 is a detail view which illustrates a method of locking the templet-plate down in place. Fig. 5 is a plan view of the machine. Fig. 6 is a horizontal section of the column and templet-plate sleeve on the line of the registering-pin, hereinafter described.

A represents a central post or column, upon which is reeiprocated the head a. by meansy of thered B, crank b, and link b', or any other equivalent mechanism. The head a carries a gang or group of awls, a', a gang or group of drivers, a2, and a spanker, a3, (see Fig. 2,) and these are arranged preferably so that two of them-namely, the drivers and the spa-ultersimultaneously operate.

C is the revolving bed. It is like .the revolving bed described in my application for Letters Patent of the United States filed January 13, 1885, and it supports a series of jacks or heelsupports, c, which preferably slide thereon. By means of these jacks or heelsupports the boots or shoes are brought successively under the templet or pressure plate E,which hasa templet-block, e. This templet .or pressure plate projects from the sleeve e',

which surrounds the column, and it has two movements thereon-first, a vertical movement, which is imparted to it by means of the pressure-block F, which is like that described in my said application, and a revolving movement sufficient to permit the holes of the tem- 4 piet-block to be used alternately, first with the awls and then with the drivers. The sleeve e of this templet or pressure plate is supported upon the yielding sleeve or ring G, which is itself supported by the springs g about the posts g', that project upward from the revolving table C and enter holes glin the ring or sleeve G. The templet or pressure plate sleeve e also has holes a5, correspondingv with the holes in the supporting-ring G, and these holes are so arranged that upon the movement of the templet or pressure plate into either of the positions above mentioned, and upon its downward movement, the posts will extend into the holes a5, and center and lock the templet rigidly in. position to the revolving table C, and when the templet or pressure plate has been so moved it is held locked down by one of the latches g3, which are attached to the revolving table O, and adapted to successively engage with the catch g on the templet or pressure plate sleeve. The ends of the posts g are preferably made tapering, and 'the entranceA to the holes a5 in the templet or`p`ressure plate sleeve enlarged. v

The templet-plate is locked by the lockingpin H in two positions-namely, when the templet-block is in register withthe awls, and when the templet-block is in register with the drivers and the locking-pin enters one of the two long slots or grooves h, arranged in the column. When the templet or pressure plate is in either of these positions, the locking-pin is forced in automatically by a spring, h', so that to move the templetror pressure plate from one position to another it is first necessary to withdraw the locking-pin, and this may be done by the lever h2, or in any other desired way. v.

The operation of so much of the invention as I have described is as follows: The boy or the attendant places the boots or shoes in successive order upon the jacks or supports, and revolves the table G to -the operator, who places the first jack or support having a boot IOO or shoe thereon in proper position under the templet or pressure plate E. Of course there may be provided suitable shoe centering` guides and a stop for 'regulating the extent of the inward movement of the jack, or the jack may be moved as described in my pending,` application of January 20, 1885, Serial No. 158,388. The heel-blank is then placed in position, and the templet moved down by :o means of the treadle M, pivoted at on, the

treadle-rod in which is connected with the templet by a pin or-block, m2, adapted to move vertically in a slot, m, in the column, and the templet-sleeve has a circular horizont-al I5 recess, into which this pin or lug,` projects, and

which permits the ten/iplet-sleeve and templet to be revolvedin relation to it. The machine is then set in operation and makes one reciprocation, and the pressure or templet plate 2o is moved downward and the heel pricked by 3o means of the unlatchingdeverg5, and the templet or pressure plate is moved upward by i the springs g, and is returned to its first position under the awls and over the next jack or work support, which has been moved into position by the movement of the first jack to the nail-driving` devices. The heel-blank is placed in position and the templet moved down upon the same and operated as before, and then moved 'forward tothe drivers. rIhis second 4o forward movement of the pressure-plate,work,

and bed C also moves the heel first attached under the spanker and top-lift holder a, so that upon the reciproeation ofthe head a a top lift is spanked upon the heel first presented to the awls; or, ifa top lift is not to be applied, the

heel is spanked and the nails for attaching the second heel are simultaneouslyY driven. After this the operation of the machine be4 Ycomes uniform and regulart-hat is, the teinplet is returned toits original position and the heel prieked, and work held clamped by the pressure-plate is moved to the drivers and the drivers and the spanker simultaneously reciprocated. It will be seen that upon one reciprocation of the machine the heel is pricked, the drivers and spanker doing no work, and that upon the next reciproeation of the machine the awls do no work while the drivers and spankers simultaneously operate.

6o The continued revolution of the table C brings the boots or shoes in succession to the teur pletplate, and finally the first shoe having the heel attached reaches the attendant, who then removes it and substitutes an unheeled shoe therefor, and the work proceeds.

.To load the templet, I prefer to employ a sleaze plate, N, adapted to be revolved upon the column A, and holding at its end the nail-holder n, having a sliding,` bottom, n. This movable hol( er is adapted to be moved to a position to the rear of the templet or pressure plate and column, where it can be filled by the attend ant, or automatically, and it is moved forward by the operator after the awls have been pricked, but before the drivers have been operated, in order that its nails may be discharged into the holes ofthe templet-block.

There maybe arranged to project backward from the post or column, and as a part of the yielding presser f'oot or block F, the plate 0, having a stationary nail-holder, 0, provided with a sliding bottom, and which is adapted to be filled with nails, either by hand or automatically,while the carrier or movableholder a is being` moved into position and the nails being driven.

lt will be observed that the upward movement of the ring or support G of the templet or pressure plate sleeve islimited by the stops l?, which 1project outward from the column, and that there are formed recesses p upon the inner side of the sleeve c', which permit the vertical movement, but limit the-revolving movement thereof in relation to the said stops.

'The sliding plates for closing the nail-carrier a and nail-holder o are moved automatically by pins located upon the templetplate and upon the nail-carrier plate, and by springs which return the sliding plates, as described in the various patents` granted to and applications made by ELA. Henderson and myself, and need not further be described here. Y

VThe advantages of the invention arise from the simplicity ofthe construction of the machine and the quickness with which the work can be performed.

Having thus fully described myinvention, I claim and desire to secure by Letters Patent of the United Statesl. In a heel nailing or attaching machine, the combination ofthe revolving table C, havin g a series of jacks or work-supports adapted to be brought successivelyinto position under the templet or pressure plate E, said templetplate, which is adapted, by mechanism substantially as specified, to have a verticaland a limited revolving movement, and the reciprocating head A, carrying,1 heelsattaching devices, all substantiallyas described.
