PAUL HENRY PAULSEN, OF STU'RGEON LAKE, MINNESOTA.

SIDE SUPPORTEB FOB SAWMILLS.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed July 13, 1918. Serial No. 244,749.

To all whom it may concern:

Be it known that 1, PAUL Hnxnr PAUL- SEN, a citizen of the United States, residing at Sturgeon Lake, in the county of Pine and State of Minnesota, have invented certain new and useful Improvements in Side Supporters for Sawmills; 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 improvements in side supporters for sawing machines, and has for one of its objects the provision of means for preventing side swinging of logs or boards while being sawed, and which obviates the necessity of dogging down the tail end of the log or board when sawing the last plank to a one inch board.

Another object of this invention is the provision of means whereby the side sup porter can be conveniently controlled manually, and which is capable of adjustment at the will of the operator.

A further object of this invention is the provision of a side supporter of the above stated character, which will be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

.Vith these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference will be had to the following description and accompanying drawing, in which:

Figure 1 is a plan view of a side supporter for sawing machines constructedin accordance with my invention,

Fig. 2 is a fragmentary vertical sectional view of the same,

3 is a fragmentary longitudinal sectional view of a supporter, and

Fig. f is a detail sectional view of means for holding a wheel to a track.

Referring in detail to the drawing, the numeral 1 indicates the frame of a sawing machine having mounted thereon the usual rotary saw 2. The frame 1 has mounted thereon and associated with the saw 2 a reciprocating carriage 3, provided with head blocks 4 and clamps 5. The aforedescribed construction relates to a well known sawing machine to which may invention is applied.

A vertical shaft 6 is secured to the frame 1 at one end thereof, and has secured thereto a wing or board -7 by strap hinges 8. The free end of the wing or board is disposed ad acent the saw 2 upon one side thereof, or upon an opposite side of the saw from the carriage 3, and consists of telescopic sections held against relative movement by means of a set screw 9, providing means whereby the wing or board can be lengthened or shortened as desired by the operator. An adjustable rod 10 is pivoted to the wing or board 7, as illustrated at 11, and carries at its free end a horizontally disposed guide wheel or roller 12. The roller 12 is adapted to travel upon one side face of a track 13. The track 13 is preferably constructed of T- shaped iron, which has its ends extended at right angles to form supporting feet or legs 14, which are bolted or otherwise secured to the ends of the frame 1. The wheel or roller 12 is of the groove type to receive the stem or leg portion of the T-shaped iron or track, and which is disposed horizontally so that the wheel or roller 12 can readily ride thereon. Arms 17 are connected to the axle of the wheel or roller 12 and carry at their free ends rollers 16, which engage the outer face of the track 13 for retaining the roller or wheel thereon. The rod 10 is capable of adjustment by being constructed of telescopic sections, so that the swing of the wing or board can be varied as desired.

A rod 17 is connected to the axle of the roller or wheel 12 and is adjustably con nected to a controlling lever 18. The controlling lever 18 is pivotally mounted to the frame 1 and by rocking said lever upon its pivot, the wing or board 7 can be moved to and from the saw 2.

In operation, a log is placed upon the carriage 3 and is fed upwardly to the saw in the usual manner, whereby upon reciprocation of the carriage the saw will cut planks or boards therefrom. The log is usually secured to the head block by the clamp 5, but when the machine is equipped with my invention, the necessity of securing the logs is entirely obviated, as the free end of the board or wing can be swung against the log to tightly hold the same against the head block.

While I have shown and described the preferred embodiment of my invention, it

will be understood that minor changes in construction, combination and arrangement of parts may be made without" departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is: i

A device of the character set forth comprising an adjustable wing pivoted at one of its ends to a saw frame, a track arranged adjacent the wing, a roller mounted on said track, a rod connected to said roller and to the free end of the wing, a second rod conthe opposite si e of the saw from that on which thework lies. v

' In'testimony whereof I aflix my signature 20 in presence oftWo wltnesses.

fim PAUL HENRY PAULSEN.
