SPECIFICATION forming part of Letters Patent No. 650,420, dated May 29, 1900.

Application filed November 11, 1889. Serial No. 329 857. (N0 model.)

To 610% whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, and having my post-office address at West Newton, in the same county and State, have invented a new and useful Improvement in Heel-NailingMachines,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,formin g a part of this specification, in explaining its nature.

The invention is an improvement upon that described in my Letters Patent of the United States dated February 14, 1899, No. 619,707; and it relates especially to the devices for presenting the work to the nail-driving and top-lift-spanking appliances, whereby the construction of the jacking mechanism is simplified and the machine adapted to be fed with shoes from the. back of the machine as well as from the front.

Referring to the drawings, Figure 1 is a view, part in vertical section from side to side and part in front elevation, of a machine having the features of my invention. Fig. 2 is a view in vertical section, taken from front to rear, of the machine. Fig. 3 is a view in horizontal section upon a line between the nailing devices and the jacks and in plan of parts below said line. Fig. 4 is a view representing the same portions of the machine represented in Fig. 3, but in a different position. Fig. 5 is a view in elevation, enlarged, of the upper part of the machine, including the cross-head and rotary head and headturning mechanism. Fig. 6 is a view in rear elevation of a portion of the head-turning mechanism. Fig. 7 is a view in elevation of the rotary head detached from the cross-head.

A-is the frame of the machine. Its sides a a and cross bed or piece a are integral or in one casting.

B is the cross-head. It carries the rotary head I), preferably having three groups of operating devices, each of which groups comprises the heel-nailing apparatus b and the top-lift spanker b As these appliances are described in said patent, I need not further refer to them here. I would say, however, that so far as the principal features of the present invention are concerned it-is not necessary to employ more than one group of operating devices and in some instances only" the heel-attaching devices.

O is the shaft of the machine. cranks c c, which are connected with the cross-head B by the connecting-rods c 0 The shaft is supported by bearing-blocks c bolted to the bed or cross-piece a D is a fly-wheel which also serves as a pulley. It is secured to the main shaft 0, and the shaft has the outer bearing din the standard d. d is a member of the clutch on the It has the fly-wheel, and d is a member of the clutch on the shaft. It is operated as follows: d is a lever pivoted at and forked at its upper end to support rolls to enter the groove d in the member 61 of the clutch. d is a spring which serves when the lever 61 is released to move the member d of the clutch into engagement with the member 01 It extends from the lower end of the lever to the frame of the machine. d is a latch-lever pivoted at d to the lever d having the latch (Z and 7 connected at its end d by the rod 01 with the treaclle 61 A spring (1 serves to hold this latch-lever up. The lever d is pivoted upon the end of the shaft cl. This shaft carries a gear d which makes one revolution for every two of the gear d upon the shaft 0. Upon the outer face of the gear (Z is a cam (Z placed to be moved into contact with the latch 01 of the latch-lever. The operation of this part of the machine is as follows: Upon Upon the gear (Z is brought againstits edge and moves the lever d to disengage or move outward the section (1 of the clutch and to also release the tension upon the operating-spring d This construction is quite analogous to that described in my said patent, varying I00 therefrom only in a slight detail of construction, which, however, has some features of value, inIthat it is somewhat simpler in construction and more direct in its'operation.

The cross-piece a of the frame has integral with it or supports a bed E. This bed has preferably a flat upper surface e, in which is arranged a guideway e, extending from front to back of the machine. In this guideway is secured a long plate 6 preferably by means of cap-plates e and there is secured to this plate 6 by means of bolts the jacks F F. The extent of forward movement or movement toward the rear of the machine of the plate e is limited by the rear adjustable stop f and the lug or stop f, formed on or attached to the plate. The reverse movement or movement toward the front of the machine is limited by the adjustable stop f and the said lug or stop f, carried by the plate, both sides of which are, it will be seen, utilized as stops in con nection with the adjustable stops f f*. The jacks are made adjustable upon the said plate E by means of the slots f in their base-sections and the attaching-bolts f so that the jacks are movable toward and from each other on the plate and are adjustable in relation to the plate. Each jack preferably comprises the base f the sleeve f, extending upwardly therefrom, the spindle f guided and held by said sleeve, and the adj usting-nut f on the lower threaded end of the spindle. Each spindle supports the lasts f In operation the operator at the front of the machine places a shoe upon the last of the forward jack, which is then in its advanced or forward position, the rear jack being under the nailing devices. He or the assistant then pushes or pulls the jack-plate to move I the forward jack under the nailing devices. This moves the rear jack to the rear of the machine and in a position to permit the assistant at the rear to place a shoe upon the last of said jack. While this is being done the operator has started the machine, attachingthe heel and toplift, if used, to the first shoe, and at the completion of the nailing, the second or rear lasthaving a shoe in position, the jack-supporting plate is moved back again, moving the front jack out of operative position with the nailing devices and the rear jack into operative position, and the machine is again started, the operator then removing the heeled shoe and substituting an unheeled, while at the completion of the second nailing the plate is again moved toward the rear of the machine, the second heeled shoe removed from the rear last, another unheeled substituted therefor, and the movement proceeds as before. placed or fed to the machine both from the front of the machine and from the rear in successive order, and its capacity is thus very considerably increased.

I prefer in a machine of this organization to use loaded heel-blanks and to feed the loaded heel-blanks and top lifts substantially as describedin my said patent.

I have described the construction of the clutch mechanism in detail in the foregoing specification, indicating the separate parts thereof; but I do not desire in this application to make any claim therefor, and such description is for the purpose of more clearly explaining the operation of the machine.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States= 1. The combination in a heel=nailing machine of heel-nailing devices, a sliding jacksupport and two horizontally=adj ustable jacks carried thereby, adapted to be adjusted toward and from each other, and also to be brought alternately into operative position with relation to the nail-driving devices, sub= stantially as described. A

2. In a heel-nailing machine, the combination of a plate or bed extending across the frame of the machine from front to rear, a support for the jacks on said plate or bed, means for adjusting the jacks and stops for limiting the movements of the jack-supporting plate in both directions, substantially as described.

3. In a-heel-attachin'g. machine, the combination with a reciprocating cross-head; of a heel-attaching device and a top-lift-attaching device mounted on said cross-head in diametrical opposition to each other, said heel and top-lift attaching devices being vertically reversible on said head; a jack-support be neath said headadapted to be reciprocated in a right line beneath the heel and top-lift attaching devices; and horizontally-adjustable jacks or work-supports carried by said jack-support, said jacks or work-supports being brought into operative relation to said heel-attaching devices alternately as the j acksupport is reciprocated.
