IMPROVEMEN T N MORTISING-MACHINE S.

To whom it ma/y concern Be it known that we, FRANKLIN A. DELAND and4 LUKE PHILLIPS, ofMemphis, inthe county of Macomb, and State of Michigan, have invented a new and useful Improvement in FootMortising and Boring-Machines; and we do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to' the letters of reference marked thereon, and being a part of this speoiiication.

` Figure l is a perspective view of our invention.

Figure 2 is a side view of thestandard.

Figure 3 is a front view of the saine.

Figure 4 is a partially vertical sectional view of the guide-block and the attachment to the reciprocating bar and spindle.

Figure 5 is a longitudinal section of the guide-block.

Figure 6 is a side view of shifting-guide, showing the method of attaching and operating the same.

The same letters indicate like parts in each ligure.

The objectA of this invention is to so construct a foot mortising-machine, that it can be adjusted so as to -allow mortising to be done in various positions of the timberbeing operated upon, that will allow of a more easy and rapid semi-revolution of the vertical bar which carries the chisel, and that, at will, may be so arranged as to be used for a boring as well as for a mortising-machine.

In order to accomplish the desired end, we construct the frame A of any suitable material, provided at the top with any suitable spring, B, resting upon the bed C, which is composed of two longitudinal bars so arranged as to leave a space between them, within which is placed the tenon D of the adjustable standard E.

Near the lower side of this tenen, andthrough the same, is a proper slot, through which the key F passes to assist in securing the standard EA to the frame.

The standard is still further secured to the upright part ofthe frame by the rods G, upon 'which proper threads are cut to receive the nuts H, and by means of which, and the before-mentioned key, the standard may be adjusted to any .desired position, and atany desired angleon the frame.

To the front of the standard are attached the guides, I, through Athe outer end of which works the reciprocating bar or spindle J.

This bar or spindle is provided .with collar K, rigidly attached, and provided with slots L upon .opposite sides, within which engages the tongue of the spring M, which is attached by a proper screw to the recipro eating guide N, which is provided with suitable jaws,

which work upon the plate O.

By means of the recess in the guide N, which engages with the collar K, the guide is attached tothe bar or spindle J, and is secured rigidly in place by the tongue of the spring M engaging with the slot L. l

F isa moitising-chisel attached to the lower end of the bar J in the usual way. v

' When it is desired to reverse the chisel, disengage the tonguel of thel spring M from the slot L, and turn the bar half way around, when the tongue will engage with the opposite slot, and hold the bar in position.

VWhen it is desired to use the machine for boring, take out the chisel P, and insert in its place a bit or auger. Then loosen the screw by which the spring M is attached to the guide N, disengage the tongue from the slot in the collar, allowingthe spring to hang in a vertical position. lhen place a proper belt, leading from a suitable drum, upon the pulley Q. whichl is rigidly attached to the bar or spindle J.

To .the front of the standard E is attached the plate O, provided witha series of holes, as shown in the drawings, `which are designed to receive a suitable pin, by means of whichthe bar or spindle is stopped in its descent, at the desired point, by the reciprocating guide striking it in its descent.

To the top of the bar or spindle J is attached a swivel, y R, to which is in turn attached the strap, cord, or chain, S, the other end of which is fastened to the spring B, which is designed to raise the bar or spindle.

To the under side of the guide N is attached the link or connecting-rods T, which at the lower end are attached to the treadle U, which operates in the usual way, and by means of l which the downward stroke is given to the bar J when the apparatus-is used for mortising, and by which the feed is given to the spindle J .when usedfor boring. V is a rest or bed, attached, by means of the bolts W, to the upright standards X of the frame. These bolts pass through slots Y, and are secured on the rear Aside of said standards X by proper nuts.

To this rest or bed is rigidly attachedthe quadrant Z, while the index A is attached to a slide playing up and down in the space B' between the standards X.

By means of the bolts, nuts, and slots last described, the rest or bed may be adjusted to any height desired, to suit various thicknesses of timber being operated upon. By their means also, and thequadrant, index, and slide, any desired angle may be given to the rest or bed, the quadrant being laid oifinto degrees to prevent the necessity of laying out, by mathematical calculation, the work.

.The back rest or guide G is hinged to the standards X, and is designed to assist in obtaining any desired lever D', which is rigidly fastened to said rest or guide secure by Letters Patent, is-
