To all 'whom 'it may concern:

Be it known that I, LAWRENCE M. ENDnEs, a citizen of the United States, and resident of Cross Plains, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvementsin Saw-Feeders; and I do hereby declare that-the following isa full, clear, andexact description thereof.

The object of my invention is to provide a simple, effective, and economical oscillating feed-rack for cross-cut saws, the construction and arrangement being such'that a log may be placed upon the rack, manually forwardly extending knee 1 havin gripped and fed to the saw, the said rack being also capable of detachment for convenience when the saw is in transportation. The invention therefore consists in certain peculiarities of constructiony and combination of parts' as fully set forth hereinafter with reference to the accompanying -drawings and-subsequently claimed.

In the drawings: Figure 1 represents a side elevation of a portlon of a 'saw and its frame having attached thereto a feed-rack embodying the features of my invention, parts being broken away to better illustrate structural features; Fig. 2, a plan View of the same showing the feed-rack partly swung over toward the saw and in section, as indicated by line2-2 of Fig. 1; Fig. 3, a front View of the saw and feed-rack, the latter being partly in section, as vindicated by line 3-3 of Fig. l; Fig. 4, a detail longitudinal sectional viewof the feed-rack looking toward the rear, the section being indicated by line 4 4 of Fig. 1, and Fig. 5, a detail sec-- tional front view of the device, as indicated by line 5-5 of Fig. 2.

Referring by character to the drawings, A, A', indlcate the front and rear' sills respectively of a saw-frame providedl with boxes constituting bearings for a saw-arbor B, which arbor carries a circular saw C-and is driven by a suitable ulley, (not shown.)

carried by the arbor. ecured to the front sill A, upon the feed-side of the saw, isfa a nback 2, which serves as a primary og support, the knee being also provided with a stop-lug lat its end. A trunnion 3 is suspended under the knee from the saw-sill A, by means of a 4bail 4, that is linked over a hook 5, which hook is secured to the underside of the sill, the ends of the bail 4being provided with eyes for the reception of the ward position, as shown in Fig. y

plementary tie-rod 7- in pivotal connection with the rear sill A', which ivotal con-nection is axially alined wit mounting of the tie-rods 6. of thektierods are provided with eyes throu the trunnion passes, the said trunmonbeing threaded -at its ends for the reception of tierod retaining nuts, as shown. The eyes of the bail 4 and tie-rods 6 are spaced apart upon the trunnion 3 to provide bearing space for front and

rear legs

8, 8, of an `oscillating feed-rack, which legs have recessed ends adaptedto fit upon the bearing spaces of the t-runnions. The upper ends of the feed-rack vlegs tinnion. The trunnion 'is heldtrussed vin relationl to.l the saw-frame by meansof tierod 6 pivotally mounted upon thefnont`sil1 :A rearward of the saw, there being a supthe pivotal' which spmmaon of Letters ment.

'straddle the knee 1 and-are connected above the same by a head-block 9, the latter being arranged to abut the stop-lug of said knee when said feed-rack is in its extreme for- 1 Vof the drawings. Extending rearward horizontal plane as the iin-back 2 of the knee. Theupper faces of the arms are bound with metallic strips, `which also extend over the adjacent surface of thehead-block 9. One stripl is ared upwardly and rearward of the arm to which it is attachedand merged into a U-shaped vertically disposed loop 11, which loop is arranged to straddle the saw and forms a log-rest at the back of the feed-v rack. The returned bend of the loop is flattened to constitute a rail 11a that is supported by a foot secured to the rear arm l0 and runs parallel with and upon the same plane as the before mentioned strips, the frdnt end of the railbeing secured to .the head-block. This'rail 11 thus for-ms an intermediate horizontal log-support in' connection with the armsand is so dlsposed with relation to the front arm 10 as to straddle the'knee.

The rear ends of the

arms

10, 10* are braced by metallic struts 12, which in turn are bolted to the lower extremities ofthe legs, the bolts also serving as retainers for a crossfrom thel legs 8, .8, are parallel arms 10, l0, which are disposed approximately upon the same strip 13 that connects and stiffens the legs at j this point. The front arm 10, as shown, projects forward at the feed-rack legs, and is provided with a hand-grip 14, whereby the feed-rack is manually oscillated to feed the -lever 15, which lever logs rearwardly to the saw and ,retractedA therefrom after each cut. Fulcrumedto the front leg 8 of the feed-'rack is -'a log-grippin is preferably serrate for that portion of its length extending above the arm" 10, 10", and terminates with a spade-handle 16 above thel 'serrated por! tion thereof. This lever is provided .for

j the purpose of gripping' orchucking a log 10 between its s errate face and the .U' hape loop 11, the saidflever being guided between lthe adjacent arm 10EL and an oset'rail 17 that is secured to said arm. The rail 17 also serves, inconjunction with the adjacent arm, as.4 a' support for the body. ofthe lgdurin the operation of 'severing the end vthereo the rail being vertically upturned at its rear endto facilitate its function;

. From the foregoing descrlption'z taken in connection with the drawings, 1t wlll be seen Athat the le s 8, 8a are so spaced apart, that.

when the eed-rack is moved rearward in its sawing-position, said legs will straddle the sill A and thus be prevented from lateral play, and when said feed-rack is .thrown for,- ward lateralplay thereof isresistedby the struts 12 taken inconnection with the front le 48. gIn the. operation, one end of a log is` dropped into the saddle formedby the upper portion of the feed-rack' from the side of the machine carrying the saw, theopposite end of the logbeing conveniently su .ported upon the ground or otherwise. Hol mg the appreciable force after the log has been moved rearward a suticient distance that its y Weight is upon the opposite side of the fulcrum upon whlch'the aforesaid feed-rack oscillates. When the desired length is cut from the lov, the feed-rack is retracted and the log moved up for new cut, and so on. Thus it is apparent that logs 4of great weight may be handled and cut into lengths by a single op eration, the .feed-rack'being so balanced as to `have this feature 'in mind.

When not in use or for facilitating transportation, the feed-rack may be lifted lfrom essaies the bail rom its hook and looping the ormer over the knee. Thus should the machine be mounted upon a truck, as commonly done with this type of/saws, these parts will all be its trunnion 3 and conveniently stored upon i the mach1ne,wh1le the trunnion itself can be swung u and out of the Way by` disen agingx elevated -so as not tov form an obstruction when said machine is in transit.

I claim: 1. A sawmg-machme having a frame, an

varbor supported upon the frame, and a circular saw carried by the arbor; a knee socured to the frame upon the feed-side of the saw, a bail suspended fromsaid frame, a

trunnion carried by the'bail, tie-rods in con nection with thefaforesaid frame and trunnion,a feed-rack having supporting -legs mounted upon the trunnion and adapted to extend above said knee,a controlling-handle in fixed relation to the feed-rack, a head-A block connecting the legs, arms extending from said legs,.a vertically disposed rear logrest in connection with the arms, the log-rest being arranged to straddle the saw, .a forward stop for' the aforesaid feed-rack carried by the aforesaid knee, and a log-gripping lever in connection with the feed-rack.l

2.- A sawing-machine having a frame, an arbor supported upon the frame, and a circular saw carried by the arbor; .a knee se' cured to the frame upon the feed-side of the saw and in the same approximate vertical plane'as the latter, a bail suspended from said frame in alinement with the knee, a trunnion carried vby the bail, tie-rods in connection with the aforesaid frame and trunnion, a feed-rack having parallel supporting ylegs mounted upon the trunnion and adapted to extend above said knee, a controlling handle in i'ixed relation to the feed-rack, aheadblock connecting the legs arms extending from .said legs, a vertically disposed U-shaped rear log-rest in connection with the arms, the U-shaped log-rest being arranged to straddle the saw, a forward stop for the aforesaid vfeed-rack carried by the aforesaid knee, and a log-gripping leverin connection vwith the feed-rack.

In testimony that I claim the foregoingl have hereunto set my hand at Cross Plains, in the county of Dane and State of Wisconsin in the presence of two witnesses.
