To (all whom H; may concer/t.-

Be it known that I, Grieken M. l-IINKLEY, aeitizen of the United States, residing at Milwaukee, in the county of Milwaukee and State t the saw -carriage for further operation thereon. Such partly j finished timber usually exists in the form of Hitches which have been cut for the purpose of quarter-sawing or resawing and is Vtemporarily stored to be worked up when a sutlicient number of Hitches has accumulated. In such finishing operation a number of Hitches is piled upona saw-carriage, so that they all individually contact with the knees of the carriage. After being so piled they are set out sidewise by the knees operated by the setworks, so that the oppo- `site edges, which may or may not be in vertiealfalinement, may be operated upon by the saw. Generallystated, theHitches are brought to the final operation of the saw by being first conveyed to the vicinity of the live rolls by a lumbercarrier. The carrier deposits the Hitches upon the upper edg'es of skids. These skids are then raised to the necessary height above an adjacent saw-carriage, and a pusharm is then brought into operation to shove the AHitches from the skids onto the saw-car- .riage and against the knees of the carriage.

1n the drawings, Figure 1 is a side view of the machine, parts of the frame being shown Fig. 2 is an end View of the machine looking from the right in Fig. 1 and omitting the carriage and carrier. Eig. 3 is a plan view, enlarged, of the linger pivoted to the upper end of the push-arm; and Fig.

4 is an elevation, partly in section, on line 41 41 of Fig. 3 of the finger and upper end of the push-arm.

A carrier l is shown (see Fig. 1) as an endless belt or series of belts running upon pulleys 2 3. Power is communicated to the carrier from any convenient source by means of a beltt, running upon a pulley mounted upon the same shaft as pulleys 3. A Hitch 5 is shown in Eig. 1 as entering into coaction with the carrier l, so as to be conveyed thereby into the vicinity of the live rolls 6. These livc rolls 6 are shown intermediate the delivery-pulleys 2 of the carrier and the sawcarriage 7 The live rolls are shown conventionally only, as they speciically form no part of the invention.

Referring to Eig. 2, skids 8 are mounted cach between consecutive live rolls, so as to slide vertically, guides 9 (see Eig. l) being provided therefor upon the frame 10. The lower ends of the skids are pivotally mounted upon the skid-shaft 11, which is supported upon oscillating arms 12, clamped at their oppositeends upon arock-shaft 13. The rockshaft 13 is mounted in another part of the frame 101. To the oscillating end of one of the arms 12 (that shown at the left in Fig. 2) is pivotally connected connecting rod 14, which at its other end is connected to pistonrod 15 of cylinder 16. The operation of this piston-rod and connected parts is under the control of the operator by ordinary val ve connections 17. (Shown in Fig. l and omitted for convenience in Fig. 2.)

Thus far described the mechanism provides for vertically actuating the skids 8 under the control of the operator. ln addition to such vertical operation of the skids 8 means must be provided for shoving otl' from the skids the Hitches elevated thereby. Such means consists of a push-arm 18, pivotally mounted upon` the skid-shaft l1 at its lower end and free to be swung about the skid-shaft as an axis by means under control of the operator.

This operating means for the push-arm includes a connecting-rod 19, at one end pivoted to the push-arm intermediate its ends and at the other end connected to piston-rod 20 of cylinder 21, mounted upon a part of the frame 102. The reciprocation of the piston-rod 2O is under the vcontrol of the operator by ordinary valve-gear 22, actuated by means of operating-handle 23.

As thus far described the operation of the push-arm is brought about by admitting steam to one end or the other of the cylinder 21, following which the piston-rod 2O willcommunicate its motion to the push arm 18 through the connecting-rod 19, causing the push-arm 18 to swing about the skid-shaft 11 as an axis. The limit of motion of the pusharm, if constructed only as thus far described, would be when the said arm approaches into proximity to the saw-carriage 7. The llitches therefore could not be positively pushed into contact with the knees 24.

In order to provide means for positively shoving the llitehes into contact with the knees 24, a linger 25 is provided. rlhis linger 25 is pivoted to the upper end of the pusharm 18, as clearly indicated in Figs. 3 and 4. The pivoted end -of the linger is formed into three tangs, as shown in Fig. 3, coaeting with similar tangs on the push-arm. The middle tang 26 is of a peculiar configuration, (see Fig. 4,) adapted in the position shown in Fig. 4 to limit Vthe lowermost position of the linger by resting the same upon the abutment 27 formed in the upper end of the pusharm 18. Toadjust the linger in its lowermost transverse position on the push-arm, a setscrew (not shown) may be passed from below through the abutment 27 of the push-arm 18, threading in the latter and provided with a lock-nut, if necessary. The push-arm 18 is formed with a groove 28, Fig. 4, at its center, so as to provide an abutment 29, which coacting with the lower edge of the tang 26 limits the uppermost position of the linger 25. The linger' 25 is therefore limited in its oscillation with reference to the push-arm 18. The purpose of this will hereinafter appear.

At the free end of the finger 25 is provided a chisel-point 30, (see Figs. 3 and 4,) which has a square shank 31 snugly fitting a square opening in the end of the linger. A pin 32, extending through the linger 25 and chiselshank 31, is riveted fast in the linger 25 and serves to hold the chisel-point lirmly in position in the linger 25.

The lowermost position of the finger 25 as to its oscillation in reference to the push-arm 18 is so designed that the chisel-point 30 will describe a path when the push-arm 18 is oscillatcd which will be a short distance above the plane of the upper ends of the skids 8 in whatever position the skids may be. This short distance is designed to be approximately one-half the thickness of a fliteh. With such design of parts the chisel-point 30 will take in a l'litch resting upon the skids 8 at any elevation of the skids 8. rlhis will follow from the fact that the push-arm 18 is mounted upon the skid-shaft 11. When the piston-rod 15 is reciprocated, the arms 12 are correspondingly oscillated and skid-shaft 11 is correspondingly elevated, and the skids 8, together with the push-arm 18, both mounted upon the skidshaft 11, are correspondingly elevated with the skid-shaft 11. In this way the skids 8 and the push-arm 18 are always kept in the same relative vertical position, or, in other words, at the same elevation. The peculiar pivotal connection between the linger' 25 and the pusharm 18 at the same time keeps the chisel-point 30 in proper working position with relation to the skids 8 and any litches that may rest thereon.

In the operation of the entire device as described the llitch 5 is brought to the transferring-machine by means of the endless carrier 1. It is then dropped onto the skids 8, which by proper manipulation of the valvegear 17 of the cylinder 16 are brought slightly above the live rolls. The llitch thus rests quietly upon the upper ends of the skids 8, being unaffected by the live rolls 6. In fact, during the operation of the transferring-machine the live rolls are not in operation. It is therefore unnecessary to certainly locate the upper ends of the skids 8 slightly above the live rolls 6, the llitches dropping either upon the upper end of the skids or upon the rolls 6. The operator now raises the skids 8 by suitable manipulation of the valve 17 of cylinder 16, so thattheliitch carried by the skids 8 is sulliciently elevated to clear the saw-carriage 7 or any liitches 51 that may previously have been placed upon the saw-carriage 7. The push-arm 18, which up to this time is in a position to the eXtreme right, as shown in Fig. 1, is now brought into operation-by a proper manipulation of the handle 23, controlling the valve-gear 22 of the cylinder 21'. The push-arm 18 is thrown to the left of its position shown in Fig. 1, the chisel-point 30 taking in the side of the flitch resting upon the skids 8, and the Hitch is thus pushed olf the skids 8 and either onto the saw-carriage 7 or on top of a llitch 51, previously shoved onto the saw-carriage 7 In either case and independent of the width of the llitch it is shoved in contact with the knee 24 of the sawcarriage, so that all the llitches piled upon the saw-carriage will rest snugly in contact with the knees 24. After the push -arm 1'8 has served its purpose it is designed to be withdrawn by proper operation of piston-rod 20 of steam-cylinder 21; but should it be neglected to bring about such operation and the skids 8 be lowered before the push-arm 18 is withdrawn therewill be no harm-caused by such failure to retract the arm 18, as the finger 25 is pivotally connected to the arm 18. Upon such adeseent of the skids 8i without retraction of the push-arm 18 the linger 25 will be swung up uponits pivotuntil the tang IOO 26 comes into contact with the edge 29 of the groove 28, and when this position is reached and upon further descent of the skids the push-arm 18 will be forced back by the contact of the linger 25 with either the edge of thesaw-carriage 7 or the projecting edge of the ilitch 51 upon the saw-carriage. @recurse it will be necessary to retract the push--arm 18 before the skids are again elevated.

In order to stillen the rock-shaft 13 and skidshai't 11, a connecting-arm 112 (see Fig. 2) is arranged near the middle of these shafts, so as to lirmly space the same at their given distance apart.

In accordance with the provisions of the patent statutes the principle of operation of the invention has been described, together with the apparatus which is now considered to represent the best embodiment thereof; but it is desired to be understood that the apparatus shown is merely illustrative and that the invention can be carried out by other means.
