d Claims.
This invention relates to a hand tool, whereby the operator can saw, chisel, drill, hammer, and the like, .the device being small and compact and-adapted to be held inthe hand of the operator.
An object cf `our invention is to provide a simple and effective hand tool, which is actuated from asuitable source of power, such as an electrical moto-r, and `which can be used as a saw, a
drill, a hammer, or a chisel, as well as various other appliances, by changing the tools in various chucks provided on the tool.
Another object of our invention is to provide a novel means of supporting the tool on the object 16 worked upon, thereby enabling the operator to saw, bore or chisel with greater accuracy.
A feature of our invention resides in the novel means of releasing certain portions of the tool from operation while other parts of Athe tool are being used.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.
In the drawing Figure 1 is a transverse sectional View of our cutting tool, with parts of the vibrating shaft broken away to show interior construction.
Figure 2 is a sectional View taken on line 2 2 of Figure ,1.
Figure 3 is a top plan View of our tool.
Figure 4 is an end View of the same.
Referring more particularly to the drawing, the numeral I indicates a tool body, preferably of suitable size to be carried in the hand of the operator. The body I is provided with a transverse and substantially horizontal bore 2, and a second substantially vertical bore 3, which inter- 40 sects the bore t. A vibrating shaft #l is mounted in the bore 2, and preferably supported on antifriction bearings 5 and 6. Drive shaft 1 is mounted in the bore 3, and the means of driving this shaft will be further described.
45 A cover 8 is detachably secured to the body I,
and the purpose of this cover is to enable the internal parts to be uncovered for purposes of repair, and the like.
Chucks 9, 9 are mounted on each end of the 50 shaft d, and a suitable tool can be mounted in either of these chucks. The tools may consist of a saw It, a chisel II, as well as other tools or devices.
Either or both ends of the shaft It may be de- 55 tached from the remainder of the shaft by a joint I2, the detachable end of the shaft being heldin an attached position by a screw I3. Thus, either or Aboth ends of the shaft 4 may be removed, together with the chuck 9, if another-part of the tool is being used.
The shaft 'I is driven from a suitable source of power, such as the flexible shaft I 4, extending from an electrical motor, or the like. The flexible shaft It is attached to the lower end of the shaft 'I by the slip joint It. A fitting It screws onto 10 the body l, thus holding the flexible shaft I4 in engagement with the shaft An eccentric Il is mounted on the shaft "I, and fits in the recess I8 in the shaft 4. An annular bearing i9 is arranged between the eccentric II 15 and the shaft Thus, as the eccentric I'I is rotated, a vibratory motion will be imparted to the shaft il. The eccentric Il is splined or grooved to receive lugs 2t on the shaft I, thereby providing a driving connection between the eccen- 20 tric and the shaft. The shaft 'I is movable within the body of the tool and relative to the eccentric Il. Thus1 the lugs 20 can be moved to engage or disengage the eccentric.
The shaft 'i is adjusted vertically in the body 25 of the tool and is held in one of two positions between spring pressed pin 2l, which extends between spaced annular rings 22. By pulling the pin 2| outwardly, the shaft l can be adjusted in the body of the tool to either drive the eccentric 30 Il or to rotate without moving the eccentri-c and the shaft 4.
A tool chuck 23 is provided on the upper end of the shaft 'I for the purpose of receiving a drilling tool, or the like. When the drilling tool is being used, the shaft 1 is disengaged from the eccentric I"I.
The chuck 23 is threaded into the upper end of the shaft l, as shown at 24, and thus this chuck can be removed when desired. 40
One or more rests 25 are adjustably mounted in the body I and, if desired, these rests can be fixed by means of a set screw 2t. This set screw is threaded into the body and bears against the rest, thereby holding the rest in fixed position. The set screw 2t* may be loosened if desired, and in this event the coil spring 21 yieldably presses the rest against the object to be worked upon.
A foot 23 is pivotally mounted on the outer end of the rest 25 for the purpose of engaging 50 contour of the object worked upon. As shown in Figure 3, the rest can be provided on either side of the body I.
Having described our invention, we claim:
l. A hand tool, comprising a body, a shaft .55
mounted for oscillating movement in the body, a cam engaging the shaft, a drive shaft, drive means for the drive shaft, disengageable means connecting the drive shaft and the cam, a tool chuck on the first named shaft, and a tool chuck on the drive shaft.
2. A hand tool, comprising a body, a shaft mounted for oscillating movement in the body, a cam engaging the shaft, a drive shaft, drive means for the drive shaft, disengageable means connecting the drive shaft and the cam, a tool chuck on the rst named shaft, a tool chuck on the drive shaft, a detachable tip on the end of the drive shaft, said detachable tip carrying the chuck on the drive shaft.
3. A hand tool, comprising a body, a vibrating shaft mounted in the body, tool chucks on the shaft, said shaft having recess formed therein, a cam mounted in the recess, a drive shaft, means to rotate the drive shaft, said cam having splines therein engageable by the drive shaft whereby said cam is rotated with the drive shaft, said drive shaft being longitudinally slidable to engage or disengage the splines in the cam, and latch means engaging the drive shaft to hold said drive shaft into or out of engagement with the cam.
4. A hand tool, comprising a body, a Vibrating shaft mounted in the body, tool chucks on the shaft, said shaft having recess formed therein, a cam mounted in the recess, a drive shaft, means to rotate the drive shaft, said cam having splines therein engageable by the drive shaft whereby said cam is rotated with the drive shaft, said drive shaft being longitudinally adjustable at the body to engage and disengage the cam.
5. A hand tool, comprising a body, a vibrating shaft mounted in the body, tool chucks on the shaft, said shaft having recess formed therein, a cam mounted in the recess, a drive shaft, means to rotate the drive shaft, said cam having splines therein engageable by the drive shaft whereby said cam is rotated with the drive shaft, said drive shaft being longitudinally adjustable at the body to engage and disengage the cam, said vibrating shaft having chucks on both ends thereof, and a chuck on the upper end of the drive shaft.
6. A hand tool comprising a body, a shaft mounted for oscillating movement in the body, a drive shaft extending transversely of the firstnamed shaft, said drive shaft extending through the first-named shaft, a cam engaging the rstnamed shaft, said drive shaft being adapted and arranged to rotate the cam whereby the firstnamed shaft is oscillated, and disengageable means connecting the drive shaft and the cam.
