Atto rn eys H. RIEGK. woonwonxme 11110111113. APPLICATION FILED SEPT. 80, 1910.
UNITED STATES ATEN WOODWORKING-MAGHINE.
Specification of Letters Patent.
Patented May 2, 1911.
Application filed September 30, 1910. Serial No. 584,752.
To all whom it may concern:
Be it known that I, HERMAN RIEGK, a citizen of the United States, residing in Greenwood township, in the county of Vernon and State of WVisconsin, have invented a new and useful Woodworking-Machine, of which the following is a specification.
This invention relates to wood working machines.
The object of the invention is to improve the mechanism for adjusting the work table relatively to a saw, whereby in a ready, rapid and accurate manner to enable a workman to gage the depth and angularity of a cut. Furthermore, to reduce the working parts to a minimum, and to assemble them in such manner as practically to eliminate danger of breakage or derangement in use.
With the above and other objects in View, as will appear as the nature of the invention is better understood, the same consists in the novel arrangement of parts of a mechanism for adjusting the work table of a wood working machine, as will be hereinafter fully described and claimed.
In the accompanying drawing, forming a part of this specification, and in which like characters of reference indicate corresponding parts: Figure 1 is a top plan view of a portion of a wood working machine embodying the improvements of the present invention. Fig. 2 is an end elevation. Fig. 3 is a view in side elevation, partly in section, and on an enlarged scale, of the mechanism for raising and lowering the work table. Fig. 4: is a detail view of part of the mechanlsm.
Referring to the drawing, 1 designates the work table, which may be of the usual or any preferred construction, and which is supported upon a frame designated generally 2. Arranged beneath the table is a shaft 3 carrying at one end a circular saw 4 that projects upward through a slot 5 in the table. On the other end of the shaft is mounted a pulley 6 which is driven from a belt 7 actuated in any preferred manner. The rear side of the table is secured to a beam 8 provided with terminal trunnions 9 that are journaled in suitable bearings 10 supported by the frame, and this arrangement will permit the table to move upward and downward as necessary.
Disposed beneath the underside of the front portion of the table is a support 11 that is carried by the upper end of two bars two of the frame beams 14. The rear wall of the bracket is provided with an obliquely disposed rack whose teeth 16 are engaged by a pinion 17 mounted upon a shaft 18 that is journaled in the lower ends of the bars 12. In order to guide the shaft of the pinion, and to cause it to remain in mesh with the rack, the bracket is provided on each side with a plate 19, each of which is provided with a longitudinal 'slot 20 to receive the shaft 18.
The means for raising and lowering the table support, which consists of the part 11 and bars 12, comprises a worm 21, the terminals of which are reduced and journaled in bearings 22 carried by the bracket, the upper end of the worm having combined with it a crank 23 by which it may be turned and thus transmit motion to the pinion 17 with which it meshes, and the latter by gearing with the rack will force the table support either upward or downward according to the direction of rotation of the crank.
Arranged upon the upper side of the table is a work gage comprising four pivotally connected bars 24, 25, 26 and 27 which are held assembled with the table by a bolt 28 and thumb-nut 29, the bolt being extended upward through the table, through the intermediate portion of the bar 26, and through a longitudinally slotted arm 30 pivoted at one end to the intermediate portion of the bar 27. The arm 30 constitutes the locking means for holding the gage at any desired adjustment relative to the saw, so that cuts of any desired angularity may readily be made.
From the foregoing description it will be seen that while the mechanism for raising and lowering the table, and for gaging the cuts, is exceedingly simple in construction, it is so designed and assembled that certainty and accuracy of operation will be insured, and further that liability of breakage or (ilerangement in use is practically obviate What is claimed is:
The combination with a wood working machine having a hinged table, of means for raising and lowering the table comprising a stationary bracket secured to the frame of the machine and provided with a rack, the opposite sides of the bracket being formed with longitudinal slots, a pinion in mesh with the rack and having its shaft projecting as my oWn, I have hereto affixed my signathrough the slots, at tatffle support embodying ture in the presence of two witnesses.
a pair of bars each 0 which connects with one end of the shaft, and a Worm carried by HERMAN RIEGK' 5 the bracket and meshing with the said Witnesses:
pinion. CARL HERREWIG,
In testimony that I claim the foregoing E. G. LAWSHA.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. G.
