SPECIFICATION forming part of Letters Patent No. 319,173, dated June 2, 1885.

Application tiled May 9, 1884. (No model.)

.To all whom, it may concern.-

Be it known that I, ROBERT A. BAUER, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful V-Jointer, of which the following is a specification.

My invention relates to improvements in V- jointers in which the carriage has a reciprocating horizontal motion upon the carriagebed, which bed oscillates on a bolt near its center, so that a V-shaped cut may be made on the stock supported by the carriage and the objects oi' my invention are, rst, to convey the motion from the shaft to the carriage by means of a universal joint; second, to oscillate the carriagebed and carriage automatically, as well as to automatically stop the motion of the carriage when it reaches the required point in either direction, and, third, to adjust the carriage so as to bring the stock thereon to or from the cutting saws or shapers. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 'l is a plan view of my invention, showing the relative positions of the carriage, carriage-bed, and saws. Fig. 2 is a rear elevation of the same. Fig. 3 is a sectional view of the carriage-bed, carriage, and supportingframe on line am: of Fig. 2, but with the bevelgearing shafts and saw-pulleys in perspective, in order to illustrate more clearly the working mechanism. Fig. 4 is a bottom plan view of a portion of the carriage. Fig. 5 is a setbar rigidly attached to the carriage, and Fig. 6 is an adj Listing-rod connected to the carriagebed used in connection with the bar shown by Fig. 5 in adjusting the carriage; and Figs. 7, 8, and 9 are detached views showing the carriage, its connecting and operating parts and supporting-plates, and their relation to each other.

Similar lettersrefer to similar parts throughout the several views.

e is the frame of the machine, which is of iron or any other suitable material.

1 is a horizontal shaft. 2 is a bevel-pinion rigidly attached to shaft 1, and 3 is a bevelpinion rigidly attached to sleeve K. The pinions 2 and 3 engage with the bevel spur-wheel 4, as shown.

V is a band-pulley rigidly attached to the sleeve K, and pinion 3, sleeve K, and bandwheel V turn on the shaft 1.

U is an idle or loose pulley used to receive the belt M, and to transfer it from pulley V to pulley T, and vice versa.

T is a pulley rigidly attached to shaft 1. The belt M runs continually in one direction, and when the band revolves T the spur-wheel 4 is revolved in one direction, and when the band M revolves pulley V the spur-wheel 4 is revolved in the opposite direction, and the carriage is thereby given its reciprocating m0- tion. The spur-wheel 4 is rigidly attached to the upright shaft G, which shaft is supported in two journal-boxes on bar H.

E and E is a bevel-gearing conveying the motion from the perpendicular shaft G to the arbor of cog-wheel 9. The arbor of cog-wheel 9 is connected to the bevel-gearing E by a universal joint, 7, so that the cogs on cog-wheel 9 may always be in line with the cogs on rackbar 11.

F and F' are belt-pulleys for running the saws A A.

14 is the carriage-bed, supported on the frame e. It is provided with a longitudinal groove extending its entire length, which forms a way for the travel of the carriage. The carriagebed is attached to the frame by a bolt, d, on which it turns a short distance, so that it may be adjusted with the carriage to or from either saw.

B is an arm supporting the journal-box of arbor J of bevel-wheel E.

I is a bar for shifting the belt lli. It is supported at one end by arm 5 and at the other by the pin O in lever P.

L and L/ are two lugs or lips on I, o'ne on either side of belt M. The lever F turns on a fulcrum near its center, and is attached at its upper end to lever Q, which lever also turns on a fulcrum near its center, as shown in Fig. 1, and is attached by means of a bolt or rivet to the shifting-bar 17. The bar 15 is attached to the carriage-bed by means of two bolts, b and b', passing through longitudinal slots in shifting-bar l5, as shown in Fig. 1, so as to allow a horizontal longitudinal movement of rco the shifting-bar 15. The bar 17 is attached to longitudinal slots in bar 17, so as to allow a longitudinal movement to the bar 17. The bars 15 and 17 are looked together by means of the latch or-catch 16, so that they move together. The shifting-bar 15 is also attached to the carriage-bed at either end by short bars turning on bolts or pivots, which bars are shown by 21 and 22, these short bars giving the i tilting or turning motion to the carriage-bed and carriage. The bar 17 has two springcatches, (shown in Fig. l by 19 and 20,) and the carriage has two downward, projecting lips, (shown in Fig. 1 by 18 and 18.) The position of the carriage in Fig. 1 shows lip 18 in con' tact with springcatch 20.

The operation of this part of my invention is as follows: Let the carriage be placed in the position shown in Fig. 1, the belt M being on pulley V, and apply the power, and the pulley V` conveys the power through sleeve K, pinion 3, spur-wheel 4, shaft G, bevel-gearing E E', cogwheel 9, to the rack-bar 11 and carriage 10, and the carriage is moved from the position shown in Fig. 1 toward the other end of the:

carriage-bed until the lip 18 comes in contact with spring-catch 19 on the bar 17, when the` downward to the pedal f at the front of the machine, and cord or chain S, connected to lug 6, passes around pulley R and downward to a pedal, f. By pressing on pedal f the belt M is shifted from the idle-pulley U to pulley T, when the motion is conveyed through shaft 1 to bevel-pinion 2 and spur-wheel 4, giving a reverse motion to the spur-wheel and through it to the carriage, causing it to travel back until lip 18 strikes against the spring-catch 20, as shown in Fig. 1, above described, when the carriage-bed and carriage shift and the belt M is passed onto the idle-pulley U, and the carriage stops. If at any time the operator desires to move the carriage back without shifting, he raises spring-latch 16, which disconnects bars 15 and 17, when the carriage is carried backward and forward in the same line.A The springcatches 19 and 20 are so constructed that they can be turned down beyond thereach of the lips 18 and 18, when the carriage will not be shifted in moving. The carriage-bed has a double track, as shown at 13 in Fig. 1, so that the carriage may be` adjusted toward or from the saws by merely placing it on the one or the other track. Beneath the carriage, and attached to it, isv the plate 26. Two screws, 25 and 25', attach the plate to the carriage. Plate 26 has projections a a c a, and above the plate 26, and bem The motion of the bar 15 takes` tween such plate and the upper part of the carriage, is the adjnsting-rod27, having beveled projections, which rest upon the projections a co a a of plate 26. The weight of the back edge of the carriage rests on plate 26. At either end of rod 27 is an adjusting-nut, 23 and 24, by means of which the rod 27 may be moved longitudinally, thereby elevating 0r depressing the side of the carriage farthest from saws A A. rIhe stock to be worked being placed on the carriage next tothe saws, the raising or depressing of the opposite side adjusts the stock to and from the saws.

Having thus described my invention, what. I claim tok have invented, and desire to secure by Letters Patent, is

1. In a V-jointer, a carriagebedpivoted at its center to a suitable frame, and which oscillates intermittently first in one direction and then in the other, in combination with a carriage which travels back and forth on said carriage-bed, mechanism whichY reciprocates said carriage, and intermittently-operating mechanism which Voscillates said carriage-bed, which latter mechanism is automatically set in motion by the carriage when it reaches its limit of motion in either direction, substantially as set forth.

2. The combination of the pivoted carriagebed, mechanism which turns said bed on its pivot, a carriage which travels back and forth on said bed,`a rack secured to said carriage, a pinion mounted on the carriage-bed which engages with said rack, mechanism which operates said pinion, and a universal `joint which connects the shaft of saidpinionwith its operating mechanism, substantially as set forth, whereby said pinion and rack may properly mesh at whatever angle the bed may be turned.

3. Ihe carriage provided with stops 18 18', mechanism whichY moves said carriage back and forth, and a bar, 17 provided with catches 19 20, with which the stops 18 18 respectively engage, and thus move said bar alternately in opposite directions, in combination with a sliding bar, I, mechanism which connects the bar 17 with said bar I, whereby the movement of the b ar 17 is communicated to the bar I; and a shifting mechanism which connects said bar I with the mechanism which reciprocates the carriage, whereby the motion of the carriage in either direction is stopped, substantially as set forth. v

4. The carriage provided with stops 18 18', mechanism which moves said carriage back and forth, a bar, 17 provided with catches 19 20, with which the stops 18 18 respectively engage, a sliding bar, I, mechanism which connects the bar 17 with said bar I, and a shifting mechanism which connects said bar I with the mechanism which reciprocatesthe carriage, whereby the motion of the carriage in either direction is stopped, in combination with vertically-movable pedals f f', and mechanism connecting said pedals respectively to the opposite ends of the bar I, substantially as set forth, whereby, after the movement of the `car- IOO riage in one direction has been stopped, the depression of one of said pedals moves said bar I and sets the carriage-operating mechanism in motion in the opposite direction.

5. The combination of the pivoted carriagebed, the sliding bar 17, mechanism for sliding said bar, the sliding bar 15, mechanism which locks said bars 15 and 17 together, and links 21 22, pivoted, respectively, to opposite ends of the bar 15, and the carriage-bed, whereby the movementof the bar 15 turns the bed on its pivot, substantially as set forth.
