'I'he principal object of the present invention is to provide a. tool holder or machine in winch a rotating tool can be presented to and moved over or toward or away from the work at many angles and from many directions, not only in a vertical plane but alsoin a horizontal plane thereby increasing not only the universal character oi the machine but also its working range.
Another object of the ,invention is to provide comparatively simple, reliable and convenient mechanism for accomplishing the results stated. Other objects of the invention will appear from the following description at the end of which the invention will be claimed.- 16 Generally stated, the invention comprises a bracket supported to swing horizontally about a vertical axis, an arm supported by the bracket to swing vertically about a horizontal pivot and provided with a track, means for clamping the arm to the bracket with the track in vertical position and with the track in' horizontal position, a motor support slidable on the track and comprising pivots arranged 90 apart, and hand operated mechanism for raising and lowering the motor support on said track when in vertical position.
The invention also comprises the improvements to be presently described and inally ced. In the following description reference will be made to the accompanying drawings forming part `hereof and in which,
Figure 1 is an elevational view with parts broken away of a tool holder embodying features of the invention and showing the parts arranged in position for the tool to operate in a vertical plane.
Figure 2 is a plan view of the top ofthe chine shown in Figure l.
Figure 3 is a View similar to Figure 1 with th parts in position for the tool to operate in a horizontal plane and also showing a modiied con.
struction of some oi the parts, andl Figure 4 is a view similar to Figure 1 with the parts arranged in the same way and showing modications.
Referring more particularly to Figures 1 and 2, v'l is a bracket supported to swing horizontally about a vertical axis. The axis is provided by a standard 2 which can be raised and lowered in respect tothe pedestal 3 by screw and nut mechanism 4. The standard is retained in iixed angular relation in the pedestal and is secured against yturningmotion by the slot and keyway 5 which when loosened permits rising and falling motion of the standard. The bracket l is turnable on the standard and can be set in position by the latch (ci. 14s-e) pwhich engages into the notches of disk 'i which is secured to the standard. The clamp 8 is a means for clampingvthe bracket to the standard. 9 is an arm supported by the bracket to swing about a horizontal pivot and the arm is provided 5 with a track Il). This track i0 is shown as arranged at the edge of the arm 9 and the track it extends laterally from the arm. As shown the arm is pivoted at-its central part to the bracket I by means of the pivot H shown as a set screw. 1o i2 and I3 are clamping screws and theyconstitute means for clamping the arm to the bracket with the track in vertical position, Figure l, and also with the track in horizontal position Figure 3. The hole It is used for a clamping screw I2 when 15' the track is in horizontal position. By providing additional holes the arm may be clamped to the bracket with the track in any intermediate position. l5 is a motor support slidable on the track l@ and it includes pivots i6 and i1 arranged 90 2o apart and provided with dial setting means i 8 and i9. The angular lever 20 is pivoted at 2i to the bracket and one of its arms 22 is connected with a counter-balancing spring 23 and the other of its arms Z4 is arranged for hand operation. 25 25 is a link interposed between the arm 24 and themotor support i 5 to which it is connected by a detachable pivot connection 26. With the parts a1'- ranged as shown in Figure 1, and by means of the adjustments described, the motor support can be 30 moved in a vertical plane by means of the handle 2t, and through the adjustments described the tool that is rotated by the motor 21 can be caused to work in a vertical plane.
. The construction and mode of operation oi the as modification shown in Figure 3 are as above described except that the arm and track I IJ are clamped to the bracket I in a horizontal position and when the rail shown in Figure 1 is adjusted into horizontal position the handle 28a is avail-` 40 able for moving the motor support along the rail, it being understood that the pivot 2'6 may be disconnected. The hand operated mechanism 2425, may be used with the arm Il) in horizontal position as shown in Figure 3 for short 45 ranges along the arm lll, and in such case the spring is relocated as at 23 and the motor support will return to the normal position at the rear of the machine. The standard 2a in Figure 3 is not movable in respect to the pedestal 3 and there 50 is but one iinished joint between the bracket Ia and the standard. This joint permits the bracket to beyturned on the standard and to be raised and .lowered on the standard. 28 is a clamp mechanism by means of which the bracket Ia 55 can be clamped to and released from the standard. On top of the standard 2* there is a bearing 29 inte sed between the arm 30 and acap 3| and w ch permits the rotary movement of the arm 30. 'Ihe hand screw mechanism 32 serves to ,raise and lower the bracket I* on the standard 2* as may be required. The construction last described is the subject matter of my pending application, Serial No. '719,111 led Apr. 5, 1934, and is not claimed herein. The principal purpose of Figure 3 is to show the track I0 clamped in horizontal position as distinguished from vertical position and further to show that the track I0 may be put into and clamped in either of these positions. The handle 28h is provided for turning and positioning the motor support.
The construction and mode of operation of the modification shown in Figure 4 are as above described except that the construction oi the bearing 29n at the top of the standard is somewhat modified or reversed and there is shown a mortising tool which comprises a bit 33 working in a tubular chisel 34 carried by a bracket 35 connected with the motor support I5.
` The character of the tool employed is not important and tools of various characters can be used. An important feature of the invention is to move the motor support vertically as well as horizontally which, in connection with the provision for adjustment of the motor support about two pivots disposed at right angles to each other, and of course of the tool carried by the motor spindle, permits of the repetition in a vertical plane of the work that can be done in a horizontal plane, and in this way the universality of the machine or holder is greatly increased and in some cases the range of the tool in respect to the work is enlarged.
It will be obvious to .those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited in respect to such matters or other# wise than as the prior art and the appended aclaims may require.
I claim:
1. In a tool holder the combination of a bracket supported to swing horizontally about a vertical axis, an arm supported by the bracket to swing vertically about a horizontal pivot and provided with a track, means for clamping the arm to the bracket with the track in vertical position or withV the track in horizontal position, a motor support slidable on the track and comprising pivots arranged apart, and hand mechanism for raising and lowering the motor support on said track when in vertical position.

3. In a tool holder the combination of a bracket supported to swing horizontally about a vertical axis, an arm supported by the bracket for turning motion and provided with a laterally extending track, means for clamping the arm to the bracket with the track in vertical position or with the track in horizontal position, a motor support slidable on the track and comprising pivots arranged 90 apart, and hand mechanism for raising and lowering the motor support on said track when in vertical position.
