WOOD-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 65 5,708, dated August 14,,1'900.

Application filed May 9, 1900. Serial Nol6,077. (N0 model.)

To all whom it may concern:

. Be it known that I, JESSE E. HERMAN, a citizen of the United States, residing at Macon, in the county of NoXubee and State of Mississippi, have invented a new and useful Wood- Sawing Machine, of which the following is a specification. 7

This invention relates to wood-sawing machines in general, and more particularly to that class employed in the sawing of logs into short lengths, the object of the invention bein g to provide a construction which may be operated by hand-power or otherwise, as may be preferred, and in which the log will be raised bodily into engagement with the saw and may be fed longitudinally after each cut for the making of a new out.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view showing the complete machine. Fig. 2 is a top plan view of the complete machine. Fig. 3 is a section taken through the machine at one side of the saw.

Referring now to the drawings, the machine comprises a base 5, at the ends of which are disposed uprights 6 and 7, having their upper ends bifurcated. Between the legs of the upright 6 is disposed a saw 8, which is mounted upon a shaft 9, journaled in said legs and having a sprocket-wheel at one end, through the medium of which the shaft, and therewith the saw, is rotated. A sprocket-wheel 11 is mounted between the legs of the upright 7 and is connected with the sprocket 10 by means of a chain 13, said sprocket 11 having a shaft 14:, mounted in journals in the legs of upright 7 and provided with an operatingcrank 15.

The log to be sawed is presented bodily to the saw by raising it thereto and is carried by a carriage longitudinally after each sawing operation. During the sawing operation the log is held upon a table comprising a rectangular frame 16, which is held below the saw and is pivoted between the uprights 17 and 18, which are fixed to a supporting-sill 19, having a third upright 20, the several uprights being mutually connected by parallel guide-rods 21.

The table, and therewith the uprights and sill, which form a supplemental frame for the table and the carriage, hereinafter described, is raised bodily by means of a lever 22, which is pivoted to the side of the upright 6 and which extends rearwardly beyond the upright '7, where it may be manipulated by the foot of the operator. To aid in the depression of this rear end of the lever, a bell-crank lever 23 is journaled upon the upright 7 and has one end pivotally engaged with lever 22, the opposite end being extended upwardly to form an operating-handle, as shown. Thus it will be seen that with a log upon the table if the lever 22 be. depressed the table will rise and present the log to the saw, the operative rotation of the saw being in adirection to draw the log in the direction of upright 6, and thus hold it firmly in proper position.

Mounted in the frame of the log-table are rollers 25, which lie on opposite sides of the plane of the saw and in planes parallel therewith. These rollers lie above the upper surface of the table to receive direct pressure of the logs under treatment and have radiallyextending spikes 26, which engage the logs and prevent their displacement longitudinally of the rollers. These rollers have also a second function-21 a, to permit feeding of the logs transversely of the plane of the saw, the logs being moved by a carriage, as shown. This carriage consists of a post 27, having transverse slots 28 and 29, through which the parallel rods 21 are loosely passed. In the slots 28 and 29 are journaled bearing-rollers 30 and 31, which rest upon the rods and act to support the post and permit the latter to be shifted readily along the rod. The post 27 has plates 32 and 33 secured to its side faces and at the upper end of the post, these plates having their upper ends bent divergingly to receive a log between them, and at the upperend of the post are disposed upwardly-directed spikes 34, which engage into the log and hold it from rotating under the influence of the motion of the saw. A shifting-cord 35 is attached to the carriage and passed through openings in the adjacent uprights, and by drawing upon this cord the carriage is moved along the guide-rods and the log is movedlongitudinally over the table. The lever 22 instead of having direct con nection with the table has its forward end g, I esa'ro forked, and between the arms of the fork is journaled a bearing-roller 36, which when the end of the lever is moved upwardly by depression of its rear-end engages the under side of the table and raises it and at the same time slides transversely thereof, and thus eliminates all tendency of the table to move away from the saw. The inner edge of the table is connected pivotally with the upright 6 by means of hooks 37 upon the table, which engage with hooks 38 upon the upright, or may have any other suitable hinge connection.

If desired, the hand-operating mechanism for the saw may be omitted and a band-Wheel may be fixed to the saw-shaft for engagement by a belt from any suitable source of power, all of which will be readily understood.

In practice the specific structure shown may be modified and any suitable materials and proportions may be used without departing from the spirit of the invention.

What is claimed is 1. Asawing-machine comprisinga saw having operating means, a tilting table, a frame movable with the table, a carriage slidably mounted in the frame and adapted to receive and feed the logs across the table, and a lever pivoted adjacent the table, said lever having a forked ond provided with a bearingroller engaging the under side of the table to tilt it when the lever is operated.

2. A sawing-machine comprising a saw hav ing operating means, a tilting table adjacent to the saw, a frame pivotally connected with the table, said frame comprising guide-rods, means for tilting the frame and table, anda carriage comprising a post slidaloly engaged with the rods, said carriage having a forked upper end to receive the logs and provided with means for moving it to feed the logs over the table.

3. A sawing-machine comprising a saw having operating means, a table pivoted adjacent the saw for tilting movement, a frame pivotally connected with the table, said frame comprising guide-rods, a carriage slidably engaged with the guide'rods and having a forked upper end to receive the logs, means for mov ing the carriage to feed the logs across the table, and a lever pivoted adjacent to the table, said lever having a forked end provided with a bearing-roll resting against the under side of the table, whereby when the lever is operated, the table with the log thereon will be tilted.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

.JESSE E. HERMAN.
