TOOL OPERATINGAND HOLDING DEVICE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed April 26, 1906. serial No. 313,664.

To all whom it may concern.-

Be it known that I, WILLIAM HENERY DONNELLY, a citizen of the United States, r'esiding at Maroa, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Tool Operating and Holding Devices; and I do hereby declare the following to be a full, clear, and eX- act description of 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 new and useful improvements in tool holding and operating devices; and my object is to provide a tool of this class which may be used for holding and operating various kinds of tools, such as wrenches, drills, and the like.

Other objects and advantages will be hereinafter made clearly apparent in the specification and pointed out in the claims.

In the accompanying drawings I have shown the preferred forms of my invention.

In said drawings, Figure 1 is a plan view of my improved tool-operating device with the tool-holder removed from the socket. Fig. 2 is an enlarged detail sectional view of the upper end thereof, showing a tool seated directly in the operating device. Fig. 3 is a perspec tive view thereof. Fig. 4 is a perspective view of the operating device, showing the tool-holder therein and engaging a wrench. Fig. 5 is a similar view showing the holder engaging a different form of wrench from that shown in Fig. 4. Fig. 6 is a detail sectional view through the upper end of the tool-operating device, showing the tool-engaging device therein. Fig. 7 is a view of the tool-engaging device removed from the operating device, and Fig. 8 is a perspective view showing the operating device used in'connection with the drilling appliance.

Referring to the drawings by numerals of reference, 1 indicates the handle of my improved tool-operating device, at the upper end of which is formed a head 2, said head having a circular opening 3 therethrough in which is seated a shank 4, said shank having a socket 5 therein and extending longitudinally therethrough. One end of the shank 4 is provided with a ratchet-wheel 6, while the opposite end thereof is threaded to receive a nut 7 and by which means said shank is held in the socket 3. A shaft 8 is secured to the handle 1 in suitable bearings 9 and has a latch 10 at its upper end, said latch being arranged to successively engage the notches in the socket 5 is square and is adapted to receive a bolt 13, which has a head 14 at one end thereof, while the opposite end of said bolt is threaded to receive a locking-nut 15, and the head 14 is provided with an elongated slot 16, in which is adapted to take the shank 17 of a tool, such as a wrench or the like, the shank being secured in the slot 16 by means of a locking member 18, said locking member having an opening therein through which passes the bolt 13 and also having a slot 19, in which takes the head 14 of the bolt, the extreme outer end of the locking member engaging the shank of the wrench or the like when the bolt 13 is drawn toward said locking device by means of the locking-nut 15. A washer 20 is disposed between the locking member 18 and the end of the shank 4, thereby disposing the end of the locking member 18 into firmer engagement with the shank 17 In operation the locking-nut 15 is loosened and the bolt 13 moved longitudinally through the socket 5 until the slot 16 in the head 14 is beyond the end of the locking member 18,

when the shank of the tool is inserted into the slot 16, when the nut 15 is again directed inwardly on the bolt 13 and the shank of the tool securely locked into the slot 16 by means of the locking member 18 pressing thereagainst. The tool is then ready to be applied to use, and as the operating device is provided with a ratchet said tool may be readily rotated in either direction by changing the direction of the latch 10 on the end of the shaft 8, thereby enabling the tool to be used in a limited space. In some instances also the tool-holding appliance may be dispensed with and the shank 17 of the tool inserted directly into the socket 5, as best shown in Figs. 2 and 3 of the drawings.

Referring more particularly to Fig. 1 of the drawings, it will be seen that when the latch 10 is disposed as therein shown the object being turned will be directed to the left; but should it be desired to turn the object in the opposite direction the'handle 11 is disposed to the opposite edge of the handle 1, thereby disposing the tapered edge of the latch 10 in the opposite direction, so that the object being turned will be directed to the right. If, however, it is desired to direct the handle 1 in a complete circle around the object being turned, the handle 11 is disposed straight out or at right angles to the handle 1, thereby locking the ratchet-wheel rigid with the head 2, so that the object being turned may be rotated in either direction at will. The latch 10 can also be disposed entirely out of engagement with the ratchet-wheel 6 by moving the handle 11 downwardly. The latch is normally held into engagement with the ratchet-wheel 6 by means of a spring 21, said spring being disposed around'the shaft 8 and between the handle 11 and the lower bearing 9.

In Fig. 8 of the drawings I have shown my improved tool-operating device as used in connection with a drill. In this connection a drill 22is placed in the socket 5, said drill and tool-operating device being held in operative position by means of a frame 23, one end of said frame supporting the object to be drilled, while the opposite end thereof forms a bearing for an adjusting-head 24, one end of said head bearing against the frame 23, while the opposite end thereof is provided with a threaded socket in which takes one end of a threaded bolt 25, the free end of said bolt bearing against the drill operating mechanism and forcing the drill against the object being drilled. By turning the adjustable head 24 and holding the bolt 25 stationary the drill 22 will be directed under pressure against the object being drilled at all times. An adjustable support 26 is also provided for the drill 22, whereby said drill is held from lateral movement.

I/Vhat I claim is 1. A tool securing and operating device comprising a handle having a head at one end thereof, a shank mounted in said head, a

2. In a tool securing and operating member, the combination with an operating-handle having a head at one end, a shank through said head, and means to rotate said shank; of a bolt seated in a socket in said shank, a head at one end of said bolt having an elongated slot therein, a locking-nut at the opposite end of said bolt, and a locking member disposed on said bolt between said shank and head to engage a tool in said slot.

8. In a tool engaging and operating member of the class described comprising the combination with a handle and a shank mounted in said handle; of a tool-engaging device comprising a bolt disposed through said shank, a head at one end of said bolt having an elongated slot therein, a lockingnut at the opposite end of said bolt, a locking device longitudinally movable on said bolt between said head and shank, said locking device having a slot therein to receive said head whereby, when the locking-nut is disposed on said bolt, said locking device will engage the shank of a tool in said slot.

4. A tool-operating device comprising a handle having a head at one end thereof, a shank rotatably mounted in said head, said shank having a squared socket longitudie nally therethrough, a ratchet-wheel integral with one end of said shank and threaded at its opposite end, a nut adapted to engage said threaded end and hold the shank in the head, a circular shaft rotatably mounted and longitudinally movable in bearings on said handle, the extreme upper endof said shaft being substantially square and having a ta: pered face to form a latch, said latch adapted to engage said ratchet-wheel, a controllinghandle on said shaft whereby the shaft may be rotated to reverse the travel of said shank or to hold rigid withthe tool-handle a spring surrounding the shaft between the lower bearing and controlling-handle and means to adjust said handle upon said shaft whereby the tension of said spring may be increased or decreased.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM HENERY DONNELLY.
