Application filed April 24,

' To all whom it may concern:

Be it known that ARTHUR A. BEACH, citizen of the United States, residing at Glendale, in the county of Los Angeles and State of California, has invented certain new and useful Improvements in a Screw-Driw. ing Device, of which the following is a specification.

This invention relates to an improvement in tool holders constructed primarily with a view .to permitting the convenient'operation of various tools in places and under conditions in which the ordinary tool holder would be of little service.

The invention is directed to a tool holder of comparatively compact form arranged to be supported for operation under ordinarily adverse conditions, the construction providing for convenient operation of the tool in either direction and for applying pressure to the tool during operation if the nature of the tool requires suchpressure.

The invention is illustrated 1n the accompanying drawing, in which: 5 Fig. 1 is a View in "side elevation showing the tool with the parts in o erative relation.

line 4..-4 of Fig. 3.

F'g. 4 is a section on Fig. 5 is a partial plan of the handle showing the latch means, whereby the same" may be connected to or disconnected from thesupporting means. p The improved tool holder comprises a frame, including a cylindrical member 1, and an offset curved member 2 at one end of the cylindrical member, the curved member terminating in a bearing portion 3 at 0 right angles to and spaced beyond one end of the cylindrical .member. 'An operating shaft 4 is rotatably supported in the cylindrical member 1 and beyond one end of said member; is formed with 'a-helical groove 5,

4 in whichis seated a 'pin 6 removably secured in afoperating handle 7. Thus by reci rocation of the handle, the operating sha t 4 is caused to revolve in the cylindrical bearing member 1. The shaft 4 extends beyond the opposite endof the bearing member 1 and is loosely provided with a bevel gear 8, and between the bevel gear 8 and the end of the frame the shaft 4 is rigidly provided with a ratchet wheel 9. A "double ended pawl 10 is carried by the bevel gear 8, and the position ofthis pawl 1924. Serial no. 703,797.

relative to the ratchet determines the direction of rotation of the bevel gear, as will be obvious.'

A tool shaft 11 is rotatably vmounted in the bearing portion 3 of the curved portion I of the frame, and this tool shaft carries a bevel gear 12 normally in cooperation with the bevel gear 8, so that in the operation of the bevel gear 8, the shaft 11 is rotated. The free end of the shaft 11 is provided with a socket 13 for the reception of any desired type of tool, here indicated as a screw driver 14, a set screw 15 serving to removably secure the tools within the socket.

'A supporting and pressure means is pro.- vided for the holder proper, comprising a threaded shaft 16 having at one end a bearing disc 17 connected to the shaft by a universal joint 18, and cooperating at the opposite end with a threaded sleeve 19, having a terminal disc 20 for convenient manipulation of the sleeve, from which disc projects a bearing stud-or point 21'. A handle member 22 is pivotally connected at 23 on the frame of the holder, the point of pivotal connection being in line with the shaft 11. This handle member projects'in line with and terminates adjacent the operating handle 7, the opposite end of the handle member slidably; embracing the threaded shaft16 and bein provided with a latch 24,[ whereby the ban 1e member may be fixed to the shaft 16 at will and at any convenient point in its length. The operative end of the latch cooperates with the threads, or may bewithdrawn to permit a free sliding connection between the handle member 22 and the shaft 16. I

- In 0 eration, particularly in places where the or inary tool holder couldnot be used, the improved-tool holder is positioned by ad'usting the holding member to cause the point 21 and ,disc- 17 to bear against opposite parts of a fixture to support the tool holder for operation. The handle member 22 is then connected to the shaft 16, so that underfpressure on the handle end of'the handle member, the shaft 11, that is, the tool holder proper, is advanced towards its work. The appropriate tool being placed in the socket 13, the handle 7 is reciprocated, and if the pawl 10 is properly positioned, the tool-14 will be operated to the end de sired. Obviousl the shaft 4 is rotarily reciprocated in t e movements of the handle 7, and it is apparent therefore that the bevel gear 8 may be positively driven in either direction at will through a proper setting of the pawl 10. Thus, for example with the use of a screw driver tool, ascrew may be applied or withdrawn.

Claims: I

1. A tool including a curved frame having a cylindrical member projecting therefrom, a tool shaft rotatably supported in the curved frame at right angles to the cylindrical member, atool socket carried by one end of said tool shaft, an operating shaft mounted in the cylindrical member, a handle for operating said shaft, cooperating bevel gears on the operating shaft and tool shaft, to drive the latter in the operation of the former, a supporting means including a threaded shaft terminally formed to permit said shaft to be rigidly held between spaced supports, and a handle member pivotally connected with the curved frame and adjustable longitudinally of the threaded shaft.

2. A tool including a curved frame having a cylindrical member projecting therefrom, a tool shaft rotatably supported in the curved frame at right angles to the cylindrical member, a tool socket carried by one end of said tool shaft, an operating shaft mounted in the cylindrical member, a handle for operating said' shaft, cooperating bevel gears on the operating shaftand tool shaft, tov drive tlfe latter in the operation of .the former, a supporting means including a threaded shaft terminally formed to permit said shaft to be rigidly held between spaced supports, and a handle member pivotally connected with the curved frame in line with the tool shaft and adjustable longitudinally of the threaded shaft. 3. A tool including a curved frame having a cylindrical-member projecting therefrom, a tool shaft rotatably supported in the curved frame at right angles to the cylindrical member, a tool socket carried by one end of said tool shaft, an operating shaft mounted in the cylindrical member, a handle for operating-said shaft, cooperating bevel gears on the operating shaft and tool shaft, to drive the latter in the operation of the former a supporting means including a threaded shaft terminally formed to permit said shaft to be rigidly held between spaced supports, a handle member pivotally connected with the curved frame in line with the tool shaft and adjustable longitudinally of the threaded shaft, and a latch on the handle member whereby oneend thereof may, be fixed against longitudinal movement relative to the threaded shaft.
