Application filed October 16, 1907. Sei-1.31 No. 397,637.

To all whom it may concern.

Be it known that we, HARRY J. Klei-1R and WiLLiAM A. HOHMAN, citizens of the United States of America, residing at Bellinghani, in the county of Whatcom and State of tVashington, liave'invented certain new and useful Improvements in Saw-Guides, of which the following is a specification.

This invention relates to new and useful improvements in wood sawing and has relation more particularly to a saw holder to be employed with undercut saws. A

In the event of a log lying up on two e1evated places at each end of the log it is impossib e to saw the log from the top or that portion which is sprung down as the log would close.upon the saw during the cutting operation, but when the sprung portion is cut from beneath the weight of the log will open the eut made by the saw and thereby assist in the operation.

It is an obj ect of the invention to provide a novel carriage to be employed in sawing a log from the under side.

It is a further object of the invention to provide in a device of this character novel means whereby the cross cut saw will be held in engagement with a log.

It is also an object of the invention to provide in combination with a device of this kind, novel means whereby the carriage may be held in operative osition. i

Furthermore, an o ject of the invention is to roducc a device of the character noted, which will possess advantages in points of sim ilicity, efliciency and durability, proving at t e saine time comparatively inexpensive to manufacture. Y

iVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangementand combination of part-s to be hereinafter more fully set forth and claimen In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, in which- Figure 1, is a view in side elevation illustrating the invention in applied position. Fig. 2, is aview in front elevation of the dcvice with parts omitted. Fig. 3, is a view in detail of a shaft -employed in the invention. Fig. 4, is a view in top plan of a detail of the invention. i

'Y In the drawings, 1 denotes the base of a.

steel frame approximatelyv U-shapcd in form.

Said frame has 'llat metal stems 2, bent adjacent the base m such manner as to cause the edges of the same to aline.

Extending centrally through the base 1, of

the frame is an upright 3, terminating at itsupper end in a for i et, in which is fixed a shaft 5. This shaft 5, projects beyond both sidesof the fork 4, and has its ends bifurcated as at 6. This bifurcated portion of the shaft 5 straddles the inner edges of the stems 2, and thereby holds the upright 3, against any undue lateral movement with relation to the base as will, it is thought, be fully understood. The fork 4, forms with the upright 3 a shoulder 7, against which bears a spira spring S, which also cont-acts with the base 1, of the frame. By means of this spring, an upward pressure is constantly exerted against the shoulder of the fork.

Loosely mounted on the shaft 5, is a. grooved wheel 9, and in one of the grooves of the wheel is adapted to rest the back of a cross cut saw 10. This wheel will readily permit the rcciprocation of the saw and as it A cuts its way in the log, the spring 8, will constantly press the saw upwardly and hold the teeth of the saw in contact with the log.

The uprightI 3, is provided in its lower end with a croc` pin 11, which is adapted to contact with a washer 12, embracing the upright. This cross pin 11, limits the upward movement of the upright.'

Adjacent to the upper end of one of the stems 2, is a perforation 13, through-which passes an end of a securing member 14, which. 1s suitably coiled as at 15, to hohl the same against displacement. The end of this in enibcr 14, terminates in an inwardly inclined pointed prong 16, which is forced into the log to be operated upon and forms a spring anchoring ineans'for the upper portion of the frame.

Secured` to the under side ofthe base 1, is, a cross piece 17, which projects beyond the ends of the base and is coiled to form bearings lS, for the approximately V-sliaped fork 19, which terminates in points '20, which engage the ing to be operated upon and form a securing medium for the lower portion of the i The fact that the fork 19, is approximately V-shapcd prevents any undue movement of the carriage during the course of the operation. T o prevent any outward movement of the carriage each member of the fork is provided with a sleeve 21, which is intended to abut a bearing 18. The sleevespZi, are connected by a cross bar 24, and said cross bar is engaged by the hooks 25, of the arms '26, which are secured to the'A base of the frame b v the securing bolts 23. rThe fork 19, is slidal'le loosely through the bearings 18, and the sleeves 21. This permits of a ready adjnstmentof the lower portion'of lthe carriage `with relation to the log to be operated upon- When the desired adjustment has been attained the fork is held against movement by the set screws 22.

The cross piece 1T, may be secured to the base 1, of the machine in any suitable or desired manner and ss shown in the drawing bolts 23, are employed for 'the purpose.

lVhat we claim is:

1. In a saw guide, a U-shaped` frame, an upright movable through the base of the frame, a shaft carried by the upright projecting therebeyond and engaging the sides of the frame, ya roller loosely mounted on the shaft, means for moving the upright longitudinally and anchoring means for the frame.

v2. In asaW guide, a U-shaped frame, an upright movable through the base of the frame, a shaft carried by the upright projecting therebeyoml and engaging the sides of the frame, a rollerkloosely mounted on the shaft, a spring contacting with the frame `and the upright for imparting longitudinal movement to the upright and anchoring means for the frame.

3. In a saw guide, a U-shaped frame, an upright movable through the base of the frame, a shaftcarried by the upright, said shaft having its ends bifurcated and embracing the sides of the frame, a roller loosely mounted on the shaft, means for imparting movement to the shaft longitudinally of the sides of the fra-me and anchoring means for the frame.

4. In a saw guide, a frame, a supporting roller carried by the frame, an anchoring means carried by one end of the frame, bearings carried by the opposite end of the frame, and an anchoring fork slidable within the bearings.

In a saw guide, a frame, a supporting roller carried by the frame, an anchoring means carried b v one end of the frame,-bear ings, and means for holding the fork against movement through the -bearings.

6. In a saw guide, a frame, a supporting roller carried by the frame, an anchoring means carried by one end of the frame, bearings carried by the. opposite end of the frame, an anchoring fork slidable within the bear'- ings, sleeves embracing the fork, means for holding the sleeves against moif'efncnt with relation to the frame, and means carried by the sleeves for holding the fork against movement.

7 In a saw guide, a frame, a supporting roller carried by the frame, an anchoring means carried by one end of the frame, bearings carried by the opposite end of the frame, an anchoring forlt slidable within the bearings, sleeves embracing the fork, and means on the frame for holding the sleeves against movement with relation to the frame and means carried by the sleeves for holding the fork against movement. I

8. In a saw guide, a frame, a supporting roller carried by the frame, an. anchoring means carried by one end of the frame, bearings carried by the opposite end of the frame, an anchoring fork slidable within the bearings, sleeves embracing the fork, a bar connecting the sleeve, arms carried by the frame engaging the bar and' means carried by the sleeve for holding the fork against movement.

9. In a saw guide, a frame approximately U-shaped an upright movable through the base of the frame, a fork on the upright, a spring embracing the upright bearing against the base of the frame and the base of the fork, a shaft carried by the fork operative therebeyond on bot-hsides and engaging the frame, a pulley loosely mounted on the shaft within the fork, and anchoring means carried by the frame.
