ROY O. DARTT, OF MONTELLO, WISCONSIN.

ANGLE-GAGE FOR DBILLS.

Application filed April 25, 1916.

To all whom it may concern Be it known that I, ROY O. DARTT, a citizen of the United States, and resident of Montello, in the county of Marquette and State of Wisconsin, have invented certain new and useful Improvements in Angle- Gages for Drills, of which the following is a specification.

The present invention relates to new and usefulimprovements in boring and drilling devices and has particular reference to supporting, gaging, and angle regulating devices for drill bits.

The primary object of my invention is to provide a bit-holding and gaging device whereby the angle and depth of a hole may be regulated by controlling the drill bit.

Another object of my invention is to provide a device of thecharacter described which may be readily applied in position on the work to be drilled, and also to provide a device of the above character which is simple in construction, cheap to manufacture, strong and durable, and effective in operation.

Other objects and advantages to be derived from the use of my improved doweling gage for drill bits will appear from the detailed description, and the claims, taken with an inspection of the accompanying drawings, in which:

Figure 1 is a top plan view of a gage embodying the improvements of my invention, 2 is an end elevational view of the same, Fig. 3 is a front elevational view of my improved gage, and Fig. 4 is an enlarged perspective view of the gage proper showing the same detached from operative position.

Referring more particularly to the drawings, wherein similar characters of reference designate like and corresponding parts throughout the various views, 1 and 2 designate the base portion of my improved gage, the inner ends of the said portions 1 and 2 being extended upwardly to provide supporting walls 3 and 4t connected by means of an adjustable plate member 5 having right angularly formed portions 6 and 7, pivotally engaged with the walls 3 and 4:, respectively, by means of bolts 8 having wingnuts 9 on their extremities.

The use of my invention, which will more clearly appear hereinafter, necessitates in some instances the securement of the device to the work. For this purpose I provide W engaging members v a d 11. ha in Specification of Letters Patent.

Patented Bee. 12, 1916..

Serial No, 93,423.

down-turned end portions 12 and 13, respectively. The down-turned portions are provided with oppositely directed retaining screws 14; and 15 for gripping engagement with the work. The base portion 2 is in the present instance the larger of the said base portions, and, of course, the section 11 is the larger, the said work engaging section being of a size coincidental with the size of the base portion 2. To adjust the workengaging element, three screws are provided, two in one of the down-turned portions 13 thereof, and one in the other portion.

The drill receiving and guiding device of my invention embodies preferably a disklike supporting body 15 mounted on the plate member by means of a bolt 16 secured against movement by wingnut 17. The work-engaging members are secured to the base members 1 and 2 by means of a plurality of bolts 14 and having wingnuts thereon. The bit' carrying members comprise an arm 18 extending transversely from the disk-like body 15 and having a curved outer end 19. The tubular portion 20 is receivable in the curved portion 19 and carries the bit 21, said bit being of any of the usual forms. Of course, it will be understood that the arm 18 and the body 15 are integrally carried as best shown in Fig. 1-. A clamping rod 22 having the U-shaped end 23 engaging the tube 20 is carried by a second lateral extension 24, the free end of the said U -shaped portion 28 extending through the outer end of the arm 18 and having a wingnut 25 mounted thereon for tightening the U-shaped portion in engagement with said tube. It is to be understood that the bit 21 must snugly fit within the tube in order to be effectively guided in operation.

The free end of the extension 24 is provided with an internally threaded enlargement 26 for reception of a screw 27 having a head 28 relatively large in circumference formed on the upper end thereof. A block 29 carried by a U-shaped bolt 30 embracing the upper end of the bit 21 and rotatable therewith serves to engage said head 28 to limit the depth to which the bit is driven.

It is of course, to be understood that various sized tubular members 20 may be employed for different sizes of bits, and it will also'be readily understood that for diiferent lengths of hits the screw 27 may be removed and a longer screw placed in its position. A

projection 31 carried by the disk-like member 15 is adapted to move across a graduated scale 32 formed on the plate 5 to indicate the angle at which the hole is being bored. The walls 3 and 4 are likewise provided with extensions 33 moving across graduated scales 34 carried by the laterally bent portions 6 and 7, of the member 5.

Thus it will be seen that the angular disposition of the bit forwardly, rearwardly, and laterally may be determined previous to boring a hole. It will also be apparent that on removing the work-engaging members 10 and 1.1 the user may place the device upon a plain surface, such as a table and retain the gage in position by kneeling thereon.

From the above description taken in connection withtlie accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of my invention'may be had, and while I have shown and described my invention as embodying a specific structure, I desire that it be understood that I may'make such changes in said structure as do not depart from the spirit and scope of the invention as claimed.

lVhat I claim as new and desire to secure by Letters-Patent is:

1. A drill guiding device of the class described, including base members, work-engaging elements associated therewith, a drill carrying frame, said drill carrying frame being angularly adjustable relative said work engaging elements, a drill carrying member carried by said frame, said member being angularly adjustable on said frame, means for said members to accomm0- date drills of various sizes, and depth regulating means for the drill.

2. In a drill guide of the class-described, work-engaging elements, a drill supporting frame associated therewith, and means carried by said frame for adjusting a drill forwardly and rearwardly for changing the angle of the drill.

3. A device of the character described, including base members, work-engaging elements associated therewith, a carrying frame angularly adjustable between said base members, a drill carrying member adj ustable on said frame whereby to forwardly and rearwardly and laterally adjust the drill.

4. A device of the class described, including base members, work-engaging elements associated therewith, an adjustable carrying frame associated with said base members, a drill carrying member associated with said frame, means for remo *ably mounting a drill thereon, a regulating screw, and means carried by the drill, for engagement with said screw whereby to regulate the depth to which the drill operates.

5. A drill gaging device of the character described, including base members, workengaging elements removably associated therewith, a carrying frame adjustable angularly on said base members, a drill carrying member angularly adjustable on said frame having indicating means associated therewith, and depth regulating means for the drill.

6. The combination with a drill guiding device including base members, an adjustable carrying frame associated with said base members, a drill carrying member comprising a disk, a regulating screw member, a bit carrying member, arms extending laterally from said disk providing retaining means for the regulating screw and said bit carrying member, and a block carried by the drill for engagement with said screw whereby to regulate the depth to which the drill operates.

In testimony whereof, I afiix my signature hereto.

ROY O. DARTT.
