FRANK P. sHEK, or BROOKLYN, new storm.

HAND-DRILL.

T 0 all whom it may concern:

Be it known that I, FRANK P. SHEK, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hand-Drills, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to hand drills of the class shown and described in U. S. Letters Patent No. 693,166, granted to me Feb. 11 1902, and No. 766,976 granted to me Aug. 9, 1904.; and the object of the invention is to simplify the construction of drills of this class and to adapt the same for use either in connection with a support or as a breast drill; and with this and other ob jects in view the invention consists in the construction. combination and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a side View partly in section of my improved drill, Fig. 2 a partial section on the line 22 of Fig. 1, Fig. 3 a partial section on the line 33 of Fig. 1, Fig. 4 a section on the line t4: of Fig. 3, Fig. 5 a section on the line 55 of Fig. 2, Fig. 6 a section on the line 6-6 of Fig. 1, and Fig. 7 a view similar to Fig. 8 but showing the parts in a different position.

In the practice of my invention, I provide a standard a having a base or foot member a which projects therefrom and is preferably provided with a fork a and mounted on the bottom portion of the stand ard ais a vertically movable sleeve 6 having a base or foot member 6 which projects in the same direction as the base or foot member a and is provided with a similar fork Z9 Secured to the top of the standard a is a bracket 0 comprising ahorizontal top plate 0 and depending end arms or members 0 and passing vertically through the bracket or support 0 at the right hand side thereof, and through the base or foot members a and b of the sleeve Z) is a shaft (Z the lower end portion of which is screw threaded as shown at (P.

ber a through which the shaft (Z passes is larger than said shaft, but the aperture 6 in the foot member 5 through which the shaft (Z passes is threaded to correspond with the thread on said shaft, and by turning said shaft the sleeve Z) with its foot member b may be raised or lowered according to the direction in which the shaft is turned, and the foot members a and b are thus made to serve as clamps by which the device nay be secured to a plate. board or other support Z) or between which a work piece to be drilled may 1 e placed, or said work piece may be placed on or over the foot member 6 if desired. The shaft (Z is provided at the top thereof with a nut-shaped head (Z and at the bottom thereof with a nut (Z Mounted on and vertically adjustable on the standard a is a supplemental bracket or support 6 provided at one side with parallel projecting ears or members 6 and at the opposite side with a yoke-shaped portion 6 through which the standard a passes and within the bracket 0 is a friction plate 6 and screws c are passed through one side portion of said bracket and adapted to bear on said plate and to increase or decrease the friction between the bracket and the standard a as may be desired, and in practice I provide a rod f which is adapted to be passed loosely through the ears 0 members c and one end of which is screw threaded as shown at f I also provide a clamp device 9 consisting of two arms hinged together at 9 and the hinged ends of which are adapted to clamp and securely hold a nut member The construction hereinbefore described with the exception of the nut member 9* relates to the support of the drill only, and T will now proceed to describe the construction of the drill. Passing vertically through the nut member which is interiorly threaded as shown at g in Fig. 1 is a sleeve h which is threaded to correspond with the thread of said nut, and the lower end of which is provided with a head if, and the upper end of which is provided with a breast piece 71. which is secured thereto by a set screw h, and passing vertically through the sleeve 71 is a shaft 2' which is preferably composed of two parts connected as shown at 2' and the upper end portion of which is provided with a head 2' The shaft 2' is provided at its lower end with a cylindrical head i which corresponds with the head 72, of the sleeve h. I also provide a tool j to which is Patented Feb. 22, 191d secured a beveled gear 7' through which the shank j of the tool j passes, and the shank y' of the tool j passes into the head 2' of the shaft z' and is provided with an annular groove, and passed through the head 2 of the shaft 6 is a set screw or similar device j* the inner end of which enters said groove, and this construction permits of the free rotation of the tool and the gear j and prevents the longitudinal movement of the shank 7' of the tool in the head i of the shaft 2'. The adjacent parts of the head If of the sleeve h and the head 2' of the shaft 1' are provided with a longitudinal groove in which is mounted a sliding lock 70 by means of which the parts it and 2' may be locked together, this feature of the construction being particularly designed for use when the device is used as a. hand or breast drill independent of the support consisting of the standard a and the parts connected therewith. I also provide a bracket support m which is mounted on the head 2' of the shaft '5 and adapted to be secured thereto by a set screw m and said bracketsupport is oblong in form and the inner side thereof is provided with screw threaded sockets m and m adaptedto receive the threaded end 7 of the rod f, and the other side of said bracket support is provided with a stud m on which is mounted a beveled gear m which meshes with the gear j and mounted on the stud m and secured to the gear 4% in any desired manner is a crank 12 having a handle m The use of this device as shown in Fig. 1 will be similar to that of other devices of this class, or of the devices shown and described in the patents hereinbefore referred to.

By turning the shaft (Z, the foot member 5 of the sleeve 6 which forms one part of a clamp, the other part or member of said clamp consisting of the footmember a may be manipulated as desired for securing the device to any support or for securing a work piece between the clamp members, and in the operation of the device, when the drill is connected with a support, one hand is placed on the breast piece 7L3 and the crank n is operated by the other hand.

The rod f and the clamp device 9 constitute a simple and effective means for connecting the drill proper with the support, and it will be apparent that with the brackets or supports 0 and e constructed as described, the drill may be mounted on the side of the standard a opposite that shown in Fig. 1 by simply passing the rod f through the bracket or support 6 and the arms g of the clamp 9 through the bracket or support 0 in the direction of the arrow at" of Fig. 1 without changing the position of said brackets or supports on the standard a, but inorder to do this the bracket support m must be provided with the two screw threaded sockets m and m, and this position of said parts is shown in Fig. 7.

The bracket or support 0 through which the arms of the clamp member 9 are passed is provided with a set screw 0 with which is connected a transverse plate 0 which is adapted to bear on the arms g of said clamp and by means of this construction the said clamp may be locked in any desired position in said bracket or support, and the bracket or support a is provided with a screw p which is adapted to bear on the rod and to lock said rod in any desired position.

W hen this device is used with the parts thereof in the position shown in Fig. 1 the drill or tool is fed forward by turning the head or handle it with one hand while the crank 11 is turned by the other, and in using this device as an ordinary breast drill without the support, the clamp g is detached from the bracket or support 0 and from the nut g and the rod 7 is detached from the bracket or support m. The nut is then run down adjacent to the head if of the sleeve h and serves as av handle which is v grasped by one hand while the head it IS pressed against the breast and the crank 12 is turned by the other hand. In this use of the device after the rod 7 has been detached from the bracket or support an a handle may be connected with said bracket or support if desired, but the nut 9* when manipulated as above set out will serve as a convenient handle for the drill wnen used in this manner.

From the foregoing description, it will be seen, that the nut g" and support m are a part of the support of the drill, and while the nut g is described herein as being mount ed 011 the sleeve 7L and the support m as on the head of the shaftz', it will be understood that these parts form in connection with the clamp g and the rod supports for the drill proper. It will also be understood that the head 7L3 forms a handle for turning the drill in its supports, and by turning said handle the drill may be adjusted vertically into any desired position as will be readily understood, the direction of said adjustment de pending on the direction in which the handle 71 is turned, but when the parts are in position for use this adjustment can only be accomplished by moving the bracket or support 0 vertically at the same time.
