lThe main object of the present invention is the provision of a tool holder constructed and arranged to receive a series of cutting points of different sizes and shapes and including a movable member in the use of which a blow may be imparted to the tool proper in the use of the latter.
The invention will be described in the following specification, reference being had )articular-ly to the accompanying drawings, in which Figure 1 is a view in elevation of a tool holder constructed in accordance with my invention. Fig. 2 is a similar view with the casing shown in vertical section. Fig. 3 is :in elevation partly in section of the tool stock. Fig. 4 is a transverse section on the line ,Jr-4. of Fig. 2. Fig. 5 is a transverse section on the line 5-5 of F ig. 2. Fig. 6 is an elevation of the chisel blade used with the holder.
Referring particularly to the accompanying drawings, my improved tool holder includes a stock 1 comprising preferably a rod-like body havin adjacent its lower end a circunifereiitially t isposed annular flange Q projecting beyond the )lane ofthe. body. Below the flange 2 the body is divided to provide spaced paralllel li s3,cen trall y between which, at their upper en( s, is arranged an abutment 4, fora purpose whichwill presently appear. At an appropriate point the body of the stock is formed with a threaded aperture 5 for the reception of a handle 6, and above and in alinement with said aperture the body is formed with a longitudinally extending rib 7. This rib terminates at its lower end above the aperture 5 and extends therefrom to the upper end of the body, being at the latter terminal provided with stops 8 ar ranged on each side of the rib, which sto s are of less height than the height of the ri as clearly shown in Fig. 2.
A casing 9V is arranged for coperation with the stop, said casing comprising a tubulnr section 10 designed to slidably embrace the stock and formed with a longitudinally extending channel or slot 11 of a size toreceive the rib 7 of the stock. The relatively inner surface of the tubular section 10 of the casing on each side the slot 11 is undercut at 12 for the reception of the stops 8 in the sait casin within said undercut ortions 12 is provided with pins 13, adapte as the casing is moved in one direction relative to and prevent complete disconnection of the casing and stock. Above the tubular section l() the casing is provided with a transverse plate or head 14, and beyond said head is circumferentially enlar ed to provide a tom of the chamber, which is formed by the head 14, is preferably covered with a Hexible disk 16 to prevent injury to the cutting points of the tools, and the extension forming the chamber 15 is threaded for the reception of a closure or cap 17, within which is arranged a pressure disk 18 connected to the cap by a coil spring 19, said disk and spring being arranged so as to exert pressure upon the blades or tools held within the chamber and revent independent play or movement of said tools in the use of the holder.
The blades, designed for use with the holder, may be of any desired type, but are preferably formed in their upper portions with a longitudinally arranged slot 20 opening through the upper edge of the blade, so that said blade may be inserted between the lips 3 of the stock and the walls of the upper portion of the slot 20 snugly embrace the abutment 4. A set screw 21 is arranged to engage the lips 3 of the stock, passing through the slot 2.0 of the blade when the latter is in place, whereby proper securingof said screw will maintain a rigid and effective connection between the blade and stop.
After assembling the parts as described the handle 6 is secured in the aperture 5, said handle projecting through the slot 11 in the tubular section of the casing to provide a handhold for the operator in the use of the imlplemcnt. n
n operation the desired force is im arted to the tool by elevating and lowering t e casing 9, the lower edge of the tubular portion 10 of said casing engiging thc flange 2 of the stock to impart t e desired pressure to the stock, to engage the stops 8 of the stock" lonvitudinal movement of the casing, and
chamber 15 in which ii p urality of tools for use with the holder may be stored. The bot' the blade. izllreferably a ft.vvashferhflis ds2- posedu n euppersur ote an toavoid)o undue wear of the parts and gleisse with unnecessary noise in operation. gli; enlarged portion of the casing formi? the chamber 15 provides a convenient han hold for the operator in reciprocating the casing, it being understood, o course, that the tool and stock carried thereby are during such operation maintained in proper osiilon on the work by obvious use of the an- The tool described provides a simple and eiective device for the use of cutting tools of any usual type, it being understood that the chamber or magazine 15 is primarily in tended to contain a series of desirable tools of different types and sizes and each constructed for operation with the stock.
Havi thus described the invention what is claime as new, is:-
1. A tool holder comprisi a stock formed with a lon tudinally extendiniib and with a threade aperture arranged low and in alinement with the rib, a casing arran ed for recirlrlrocatory movement relative to tle stop and aving a longitudinally extendin slot to receive the rib on the stock, a hand e passing through said slot and en in the a rture in the stock, sto blockgsagarrgied byptehe stock on each side o the rib, and pins carried by the casln to engage said stop blocks and limit the re atively outward movement of the casing.
2. A tool older comprising a stock formed with a lon `tudinally extendin rib and with a threade aperture arranged elow and in alinement with the rib, a casing arranged for reciirocatory movement relative to the stop an havin a longitudinally extending slot to receive t e rib on the stock, a handle passing through said slot and engaging the aperture in the stock, stop blocks carried by the stock and arranged on each side of the rib, said blocks being of less height than the rib, the inner surface of the casing on opposite sides of the slot being undercut to receive the stop blocks, and pins arranged in said undercut portions to engage the stop blocks.
In testimony whereof I aiiix my signature in presence of two witnesses.
