WILLIAM R. AXE, OF BELOIT, \VISCONSIN.

MORTISING-MACHINE.

Specification forming part of Letters Patent No. 25,479, dated September 20, 1859; Application for Reissue in two divisions filed March 13, 1873.

To all whom it may concern:

Be it known that I, WILLIAM R. AXE, of Beloit, in the county of Rock, and State of Wisconsin, have invented certain new and useful Improvements in Machines for Mortising and Tenoning Window Blinds and Sashes, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, in which- Figure l, Plate 1, represents a perspective view of the machine showing the several parts in their relations to each other when arranged for mortising. Fig. 2, Plate 1, is an enlarged View of those parts used for boring and mortising, showing the same in longitudinal section. Fig. 3, Plate 1, is a view of the saddle for holding the hollow chisel. Fig. 1, Plate 2, is an inside view of the table for holding the stuff during the operation of cutting. Fig. 5, Plate 2, is a transverse veru tical section of Fig. 4 with Fig. 6 attached thereto.l Fig. 6, Plate 2, represents a plan view of the gage used when tenoning. Figs. 7 and 8, Plate 2, show two views of the tool which is inserted in place of the mortising tools for milling or cutting the tenons on blind slats, etc.

Similar letters of reference indicate corresponding parts in the several figures.

This invention is an improvement in the machinery used for the manufacture of sash and blinds, whereby the work can be accomplished with great speed and facility, at the same time the several parts are simple and not liable to derangement under any ordinary usage.

My invention consists in the employment of a square hollow chisel, inclosing a rotary auger of a peculiar shape for the purpose of boring and squaring the hole at the same operation, at the same time obviating the clogging up of the bit as is usually the case where a chisel and bit are combined for boring and mortising at one and the same moment. It also consists, in connection with the above specified device, in the employment of a reciprocating table which is to be operated by a foot lever so as to bring the material to be Inortised or tenoned up to the chisel which is rotated in a manner hereinafter described, said table being provided with a feed roller actuated by a pawl and ratchet during the movement of the table from the chisel so as to feed the stile along the table as the mortising proceeds; and in conjunction with this reciprocating table is an adjustable bed-plate for adjusting the work to the chisel: all as hereinafter described.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

The machine is mounted in a suitable wooden frame, A, having, bolted on its top, a cast iron frame, B, with standards and arms, cc 0c, which support two steel bars, D D, secured by four nuts, E E E E.

*F is a spindle driven by a counter shaft, Gr, to which it is connected by a belt, H. This spindle is shown clearly in Fig. 2, working in brass journal boxes, I, and to which is connected the auger, J.

K, is a hollow chisel supported by a wrought iron saddle, L, which is secured to the frame, B, by studs, m m, and may be taken off or put on by the nuts, a a, the saddle is shown clearly by Fig. 3, in which the hollow chisel, K, is shown made fast by set screws 0.

In Fig. 4, Plate 2, the table, W, is shown, which slides on steel bars, D D, connected by a rod, P, having an elbow connection, Q, which can be adjusted to increase the power of the lever. Q, is again connected by the foot lever, R, by a double rod, S. When pressure on the lever, It, has forced the table, WV, up to the chisel, K, the spring, T, returns it back to its original position. W is an inside table which can be adjusted by set screw o, to suit thickness.

In Fig. 5, Y is a pin .which has a feed roller, Z, fitted to the upper part. This roller is serrated on its surface, as is cornmon to feed rollers of this description. Underneath of this roller is a ratchet wheel, c', which is keyed to the pin Y; and below this ratchet wheel is a pinion spur wheel, c, having a pawl, D, which operates the ratchet and turns the feed roller at each motion of the table, by means of a rack, D, projecting out from the arms, c, of standard, B, which engages with the teeth of the spur, c. l

In operating this machine for sash the piece tube divided off and mortised is laid on the table, W', which can be adjusted by the thumb screw o. The gages, a: ce, are moved on a graduating plate, s, which is graduated to suit the different sizes of glass. The foot is then placed upon lever, R, which draws tables, W and W', up to the auger, y', revolving in the hollow chisel, K. After the mortise is made the spring presses the table, 7, back again.

In dividing off and boring blind stiles the saddle, L, is taken away with the hollow chisel K, by taking off the two nuts, n. n. The stile is then laid on W", the back of it pressing against the fluted roller, Z, which is recessed in the upright part of table, W. The blind stile is then fed by the serrated roller, Z, as the table moves from the auger, the distance being regulated by collars on the steel bars, D D. When the table moves from the auger, the pawl, D', strikes the ratchet tooth which secures the pinion to roller, Z, which, when secured, moves the stile; but when the table moves toward the auger it reverses the motion of the pinion. The pawls then slip over the ratchet teeth. To mill a round pivot on each end of a blind slat, the auger, J, is taken out from the spindle, F, together with the bushing piece'r, shown in Fig. 2. The milling tool, G, as

shown in Fig. 8, Plate 2, is then placed in the spindle, F.

The feed roller, ratchet wheel, spur wheel and pin, Y, are removed, and a gage late R, as seen in Fig. 6, Plate 2, is then p ace on the table, and screwed thereto, passing through the recess for feed roller, Z, as shown by Fig. 5, Plate 2, the roller in this figure should be removed, as above stated. The slide, F', is set according to the required length. The end of this slide is notched to receive the end of a slat after the pivot has been milled. The cutter for milling is shown clearly by Figs. 7 and 8, H being the cutter in evolute form, the cutting edge having saw teeth, cutting from the center, until the tooth, z', which is next to the hole in the center of the circular plate, J', forms the size of the ivot.

K, is a knife made fast to tie inside of the circular plate, J, which can be adjusted to cut off the pivot to any required length. The piece to be milled is laid on the gage plate, R. The required length is obtained by moving the slide, F. The foot is placed on lever, R, which draws table, W, as before described.

What I claim as my invention, and desire to secure by Letters Patent, is

The gage plate, R', and slides, a' w, in combination with the reciprocating table, W, and adjustable table, W, arranged in the manner, and for the purposes, represented and specified.

WILLIAM R. AXE.
