FRANK PA'IE SNEED, 0F KEMPER, SOUTH CAROLINA.

TRIP-BLOCK.

To all whom it may concern:

Be it known that I, FRANK PATE SNEED, a citizen of the United States, residing at Kemper, in the county of Marion, State of South Carolina, have invented certain new and useful Improvements in Trip-Blocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices employed in saw mills in connection with log turning operations, and has for its object to provide a simply constructed triangular shaped portable block device whereby the turning of logs is facilitated.

The principal object of the invention is to provide a portable device of the character above described, whereby the same can be readily and conveniently adjusted into an accurate position, and further in the provision of means for properly holding the said device against displacement when properly positioned.

With this and other objects in view, the invention consists in certain novel features of construction as hereafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a perspective view of the improved implement viewed from above. Fig. 2 is a perspective view of the improved implement viewed from below. Fig. 3 is a side view of a portion of a saw mill carriage and log platform with the improved device in position thereon.

The improved device comprises a hollow triangular shaped block, represented as a whole at 10 and open at the upper and lower sides with the upper side 11 inclined to the longitudinal plane of the block. By this means one end of the block is larger than the other, and formed integral with the larger end is a handle 12. The handle 12 referred to forms a very important feature of the invention and provides a heel for the block to prevent the same from moving out of its portable and adjustable position, the lower surface of said heel being substantially on a plane with the remaining portion of the block.

Projecting from the lower side of the block are a plurality of spurs 18, the latter designed to bear in the face of the log Specification of Letters Patent.

platform 14 as shown in Fig. 2, and thus prevent the slipping of the block when the pressure is applied, as hereafter more fully explained.

Formed through the side members of the block near the inclined side 11 are a plurality of apertures through which small shafts or pins 15 extend, and mounted for rotation upon each of the pins is a roller 16, the rollers projecting at one side beyond the inclined face of the block as shown.

In Fig. 3 is shown an end view of a portion of a saw carriage, represented as a whole at 17, and the portion of a conventional log platform represented as a whole at 14, the improved trip block being located upon the platform adjacent to the saw carriage, as shown. A portion of a log is shown upon the carriage in position to be overturned. With a device thus constructed when a log is to be turned the carriage is manipulated to locate the log, represented conventionally at 19, with the face 20 from which the slab has been cut adjacent to the platform 14, as represented in Fig. 3. The block 10 is then located upon the platform with its smaller end as close as possible to the flat side 20 of the log. The log is then overturned by cant hooks in the usual manner until the flat side 20 engages the rollers 16. Then as the rotation of the log continues the inclined position of the rollers causes the log to readily move by gravity to the required position upon the carriage with the flat side 20 downwardly. The spurs 13 serve effectually to prevent the outward movement of the block when the pressure is applied, and thus holds the block to its work, as will be obvious.

The improved device is simple in con struction, can be inexpensively manufactured and strongly constructed, and manufactured of any required size or of any suitable material. As many of the blocks may be employed as required, and when relatively long logs are to be overturned, a plurality of the blocks will generally be employed, but for shorter blocks one block only will be employed. The blocks may be located at any required point upon the platform, as the spurs 13 do not require that cavities shall be produced for them but pro duce their own cavities when used.

The improved blocks are located upon the platform 14 when the logs are to be overturned, and are then removed so that they do not interfere with the operations of the carriage. The blocks thus do not form obstructions to the lumber as it is cut from the logs and falls upon the plat-form.

What is claimed is A device of the character described com prising a triangular shaped body having a longitudinal opening formed therein, whereby oppositely located side walls are formed, spurs extending from the lower opposite bearing surfaces of said body, a plurality of rollers mounted for rotation in the upper inclined faces of the body thus formed and In testimony whereof, I affix my signa- 20 l ture, in presence of two witnesses.
