Application nea June 15, 1889.

the top lift, forming vslugging-holes through' the top lift, driving slugging-nails, and leveling and breasting the heels proceed simulupon practically as many boots or shoes.

In the drawings, Figure l is a View in side elevation of a machine having the features of my in-vention. Fig. 2 is a view in horizontal section and plan upon and below the line ma:

of Fig.` 3. Fig. 3 is a vertical central section of the machine. Figs. 4, 5, 6, and 7 are detail views.

A is the frame of the machine.

B is a vertical base or column rising from the frame of the machine. Y

C :is a head having a bearing upon the column or post B and reciprocated by means of a powerful crank D and the heavy connecting-rod d. The cranlrshaft d has suitable bearings in the frame of the machine and is connected at each end by gears d2 with the pinions (Z3 upon the pulley-shaft (Z4.

E'is a vertically-movable table supported by and arranged to slide upon the column B.

It supports the sole-nailingptemplet F, the

pricking-templet F', the attaching-nail-driving templet F2, the topliftattaching templet F3, the slugging-templet F4, and the leveling and breasting templet F5. Each templet preferably is in the form of a rectangular block and is secured in a holding-recess in the table E to have a slight vertical movement therein,in order that upon the application of pressure to the templets there may be no undue strain brought to bear directly upon their table or support E.

Serial No. 314,484. (No model.)

l have represented each templet as provided with avertical movement in its holdingrecess of the table by means of the screws p p2 and the stops p3 p4, and the templets are locked in their holding-recesses by means of buttons p5 or in any other desired way.

The table E preferably is moyed upward vertically by springs e, (see Fig. 1,) and it is moved downward upon the downward movement of the head C by the springs e2, the' springs e2 being compressed sufficiently upon the downward movement of the head C to overcome the resistance of the springs e. Stops e3 limit the extent of the upward movement of the table. The table is connected with the head by means of rods e4, which extend into holes in the head, and which serve to hold the table and its templets in register with the operating devices carried by the head and also as supports for the springs e2. Upon the bed A of the machine is an annular plate G, which is adapted to be rotated or turned upon the bed, and this plate supports the jacks H, which have a radial sliding movement thereon in ways h. There is one more jack employed than there are templets used, and the table E preferably is cut away and shaped at e5 (see Fig. 2) to not extend over one of the jacks, or the jack which happens to bein that position.

The plate G is represented as rotated or turned by a roll M, which bears against the edge g of the plate, and whichis turned by means of a pulley m on the lower end of the roll-shaft m', (see Fig. 1,) the pulley 'm2 upon a counter-shaft, the pulley ma upon the pulley-shaft d4, (see Fig. 3,) a belt m4, extending from the pulley m3 to the pulley m2, which is a double pulley, and another belt m4, extending from said pulley m2 over the roll m3 to the pulley m. The plate G is held in position by means of a spring-pin n, (see Fig. 1,) which is adapted to enter in successive order the registering holes n in the plate G, there being a separate registering hole for each jack. The sp ring-pin 'n extends from the operatinglever n2, the said lever havin@ a handle n3 pivoted at n4, and has an end m5, against which a spring a6 acts. (See Fig. 1.)

The head C carries or supports a gang or group of sole-nail drivers c, agang or group of aWls c ,a gang or group of drivers c2 for driving the 4heel-attachin g nails, a gang or group of awls c3 for forming holes in the heel-blank for the reception of slugs, a gang or group of drivers c4 for driving the slugs, anda breast-.

ing-knife c5. Each of the blocks supporting the respective drivers or awls and breasters, preferably are pressure-blocks-that is, their under surfaces come in contact with the upper surfaces of the respective tem plets with which they operate. Thereis upon the under side of the templet F a heel-blank-holding device comprising a V-shaped spring-operated slideplate O and a gage 0, (see Fig. 7,) and asimilar device is carried below the templet F3 for holding the top lift.

In operation the operator stands opposite the spare last, (see' Fig. 2,) removing therefrom a heeled shoe and placing thereon a shoe with its heel-seat unnailed, and at the same time causing the head C to make a .reciprocation, the other lasts, with the shoes thereon, being in operative position under the various vtemplets FF F2 F2 F4 F5, whereby aheel-seat of one shoe is being nailed, a heel-blank upon another shoe pricked, a heel-blank on still another shoe attached, a top lift applied to the attached heel-blank of another shoe and pricked for slugging, a heel on still another shoe slugged, and the heel upon the sixth shoe leveled and breasted. It will `be 0bserved that by this organization and operation there is produced upon each reciprocation of the machine one completely-heeled shoe, the heel-seat of which has been nailed, the heel attached, top lift applied, a second lineof nails driven into it, and the/heel leveled and breasted. Upon the completion of one reciprocation of the machine the operator causes the table bearing the jacks to be lturned sufficiently to advance each jack from one templet to the next in order.

The level or height of the lasts in relation to the j ack-posts may be varied by removable adj Listing-blocks p, which are made of different thicknesses, and whichare inserted between the under surface 4of the last and the upper surface of the post. (See right-hand jack, Fig. l.) The nails and slugs preferably-are loaded to the holes of the templets F F2 F4 by skimmers operated by boys, and a boy likewise removes the pricked heel from beneath the templet F to a position beneath the templet F2. l

It Will be observed. that the vorder of the operations upon the heel may be varied according to the kind of work required. I have referred to the slugging of a blind-nailed shoe. The apparatus can as Wellbe used for flush nailing with two lines of attaching-nails, or one line of attaching-nails and another line of slugs. In some instances the sole nailing and leveling and breasting devices may be dispensed with. p

Having thus fully described my invention, I claim and desire to secure by Letters Pate'nt of the United States-'- 1.
