BORING AND ROUTING MACHINE.

i ,acceso Application lerl August 15, 1919.

To all whom t may concer-n.'

Be it known that I, DANIEL S. Sco'r'r, a citizen of the United States, residinor at Baltimore, in the State of Maryland, ave invented certain new and useful Improvements in Boring and Routing Machines; and I do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to boring and routing machines. The object oi my invention is to provide a portable prime mover, such as an electric motor with detachable mechanisms, one of which can be used for boring holes and the other of: which can be used for routing. A further object oi my invention is to provide the mechanism for routing with suitable gages so that the path of the routing cutter may be determined thereby.

In the drawings Figure 1 is a side elevation of an electric motor, showing my improved routing inachinc detachably secured thereto, the routing machine being shown in section.

Fig. 2 is a view of the routing machine shown in Fig. 1, when viewed in the direction of the arrow 2 in said figure, the cutter being omitted for the sake of clearance.

Fig. 3 is a sectional view of the boring mechanism, the locking pawls being omitted for the sake of clearance.

Fig. 4 is a view of the locking pawls and locking pins, when viewed in the direction of the arrow et in Fig.` 2.

In the drawings, represents an electric motor which may be of any improved design, and it is preferably provided with a handle l1. rlhe motor 10 is provided with a sleeve 12 and in the latter there are secured locking pins 13--13- The shaft 14 of the motorextends through the sleeve 12 and terminates in a square end 15.

My improved routing mechanism consists of the casing 16 provided with a sleeve 17 which fits snugly upon the sleeveV 12 and is provided with right angle 'slots 18-18 for the reception of the locking pins 13-13- The locking pawls ,19--19 are pivotally secured upon the sleeve 17 by the screws 20-20- The casing 16 is provided wit a bottom 21 secured thereto in any improved manner, and said casing and bottom are each and the roller is Specification of Letters Patent. i Patented J 3,11, 25, 192L Serial No. 317,652,

provided with bosses, in which are cylindrical bearings for the reception oi' the bearing portions 22H22 of the bevel gear 23. The bearing portions 22-22 are provided with a central square hole 24 for the reception of the squared end 15. rlhe casing 16 is provided with a sleeve 25 in which is revolubly mounted the shaft- 26, upon one end ci? which is secured the bevel gear 27 which meshes with the bevel gear 23, and upon the other end of which is secured the routing cutter 28. The gage rollers 29 and 30 are slidably secured upon the casing 1G by the screws 31-31, the roller 29 being adjustable in a vertical plane and the roller 30 being adjustable in a horizontal plane.

The casing 16 is also provided with a handle 32.

The operation of my improved 'routing machine is as .ollows`:

The free ends of the locking pawls 1919 are to be moved upwardly until the bodies of the pawls clear the slots 18-18; the sleeve 12 is then to be introduced into the sleeve 17 and the pins 13-13 introduced into the slots .18-18. The sleeve 12 is to be pushed in until it occupies the position shown in Fig. 1. During this operation, the cutter 28 is to be revolved until the hole 24 is in proper alinernent with the squared end 15. lhen the pins 12B-13 reach the bottom oi' the vertical portion of the slots 18%18, then the motor is to be turned in a clockwise direction bringing the pin 18-13 to the ends of the horizontal portions of said slots. The locking pawls 19-19 are then to be moved to the position shown in Figs. 1 and 2, thus preventing disengagement of the pins 13-13 from the slots 18-18- The roller 29 is then to be set to determine the proper depth of cut to be made by the cutter 28 in the work to be set to determine the location at which said cut is to be made. The operator then grasps the handles 11 and 32, and applies the cutters to the work.v

` My improved drilling mechanism consists of the drill chuck 34; which is secured upon the shaft 35, the latter being provided with a square hole 36 and a groove 37, in the latter of' which the point of the screw 38 lis in* troduced and serves to prevent displacement of the shaft with reference to the sleeve 39. The sleeve 39 is provided with a handle 40, and with slots similar to the slots 18--1S.

' guide the drill While Vit is at Work.

yDrillscan then be introduced in the drill chuck 34 and the operator applying his hands to the handles ll and 4() can? then Thus it will be seen that I provide a simple, cheap and eilicient boring and routing machine which can be variety of uses.

applied to a Wide l. The combination With a motor, including a driving shaft, of a sleeve thereupon, pins in said sleeve, a second sleeve mounted upon- Saidrfirst named sleeve and hai/'ing slots engaging said pins, a routing machine supported by said KVsecond 'sleeve and including e gear provided With a square driving hole and a square on said shaft engaging Vsaid hole'. i

2. In a routing machine, the combination with a casing and fixed bearings in Said cesing, of a cutter revolublysupported in said bearings, a gage adjustably secured to said casing for limiting the depth of cut made by said Glitter and a Second gage edjustably secured to said casing for determining the location of said out.

In testimony whereof I ailix my signature.

DANIEL S, SCOTT.
