SPECIFICATION forming part of Letters Iatent No. 470,357, dated March 8, 1892. Application filed April 9 1891'. Serial No. 388,281. (No model To @ZZ whom it may concern/.-

Be it known that We, GEORGE W. BUGBEE and FREDERICK BANNER, citizens of the United States, and residents of Cincinnat,in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Rip-Saw Machines, of which the following is a specification.

Our invention relates to that class of ripsaw machines which employ an automatic feed.

The object of our invention is to provide means for adj usting the saw and feed simultaneously and also to provide separate means for adjusting the feed independent of the saw adjustment.

The various features of our invention will be fully set forth in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 is a top plan view of our improvement. Fig. 2 is a side elevation of the headblock and feed-adjusting mechanism. Fig. 3 is a side elevation of the head-block with the saw-adjusting mechanism attached. Fig. 4 is an end elevation with the table shown in section. Fig. 5 is a detail view of thefeedadjusting arm. Fig. 6 is adetail view of the guard.

The frame-work of the machine comprises standards 2, on which the table 3 is supported.

4 represents the main shaft, supported in journal-boxes 5; 6, the main driving-pulley, which receives its motion from the countershaft and the ordinary binding-pulley, so as to allow the said driving-pulley 6 to be vertically adjusted. 7 represents a driving-pulley on l said main shaft; 8,a belt passing over pulley 9, loosely mounted upon the shaft 10, for communicating motion to the feed-wheel. In order to vary the speed we provide an additional series of driving-pulleys 1l 1 2, to which the beltmay be shifted to decrease the speed, if desired.

We prefer to employ a small feed wheel or saw A, and in order to give it proper speed we provide a train of

gears

14, 15, 16, and 17, the gear la rotating with pulley 9 to transmit motion from the pulley 9 to the shaft 13, on the end of whichthe feed-saw is mounted. This feed runs vertically over and on a plane with the travel of the rip-saw B. The said gearing and shafting are mounted upon a bracket C, which is mounted upon the headblock D. This head-block D is gibbed to the standard 2 by dovetail grooves, the standard 2 being provided with tongues a a to fit the same. 4

b represents a series of set-screws which pass through the head-block D and engage against the backing between the same and the tongue a, so as to take up lost motion. Said head-block D is screwthreaded to receive shaft E, on the end offwhich is a bevel-gear 19.

l 2O represents another beveled gear keyed upon a shaft which journals in the sleeve 2l. 22 represents a hand-wheel for turning the said shaft and bevel-gear 20, driving the bevelgear 19, and raising and lowering the headblock D by the revolving of the threaded shaft As the feeding mechanism ismounted upon the bracket C, which is mounted upon the head-block D, the turning of the wheel 22 simultaneously raises the saw mounted on the head-block and the feed and its gearing also mounted on said head-block, so that the adjustment of the saw B and the feed A vertically are uniform. Y

It is desirable to adjust the feed independent of the saw, which is accomplished in the following manner: The shaft 10 is preferably stationary, and mounted in a sleeve 23 on the head 31, which swivels on the bracket C, being clamped in the desired position by bolt 32.

30 represents a sleeve, in which the feedshaft 18 journals. This sleeve is swiveled upon shaft 10 by means of

armsl

25 and 26, through which the shaft 10 passes. 36 represents a lever, also loosely pivoted upon the shaft 10 and having at one end a lug 37, which projects beneath the arm 25. The opposite end of the lever 36 is provided with a worm 27, driven by a hand-wheel 28. The worm 27 meshes with the teeth of a segment 24, which projects from the sleeve 23. As the worm is adjusted along the face of the segment the lug 37 raises or lowers the outer end of arm 25, which turns upon its center 10, as indicated in Fig. 3. y n

It is sometimes desirable to move the feed out of the way, and this is accomplished by turning the head 3l upon its center 32 until it is ont of the Way, the belt 8 being first removed. The upper end of bracket C is formed into a seat 33, on which the annular seat 34 of the 'head 31 rests.

It is preferred to employ the diagonal mechanism to hold the said feed in its proper lateral position by the mechanism shown in Letters Patent No. 307,601, granted to John R. Thomas November 4, 1884, but othermeans of holding the feed in lateral position may be employed in lieu thereof, if desired.'

It is preferred to have the feed A a supplemental saw, and for this means it is provided withteeth, but other meansof feed vmay" be employed'in lieu thereof.

In order to hold the `stuff down upons the table vor t'o prevent'it from being raised up by the 'action of the saw We provide'ay finger-'guard F, lwhich is mounte'dpon' the forwardp'end of vthe sleeve 30, projects f backward past 'the saw and prevents thestuif from being thrown forward violently. In sawing stuff of different thicknessesy 'it 'is desirable to adj ust the saw Vertically,-so that it'will only'a little more' vthan reach through the stuif to be sawed. The adjustment of the saw to the feed isreadily accomplished in' one movement by turning the hand -fwlieel 28, as before vexplained. The feedv may be adjusted inde'- pendent of the adjustment of the saw to accommodate different thickne'sses'of stuff, if desir'edjor for any other purpose; In Fig. 4t the feed A- isv shown thrown upA 1vuntil the arms 25 and26 are vertical, l
