Specification of Letters Patent.

Patented Dec. 10, 1907.

To all whom it may concern:

Be it known that I, GEORGE M. HINKLEY,

a citizen of the United States, residing at The accompanying drawing shows one form of the invention and in which,

Figure 1 is an elevation, parts being broken away. Fig. 2 is a plan view of a slide with its two branches. Fig. 3 is a vertical sectional detail of one of the slide branches showing the gabled structure. Fig. 4 is a broken vertical section of the edger on line 4, 5 in the direction of arrow 40, Fig. 1. Fig. 5 is a broken vertical section of the edger on line 4, 5 in the direction of arrow 50, Fig. 1.

In the machine shown, the edger frame consists of end supports 11, 12 connected by girders 13 at the front and back of the machine, the one at the back not being shown.

The saw arbor 14, is centrally longitudinally mounted in the edger and supported at the ends of the edger in boxes 141 carried by arms 142 detachably fastened upon the end supports 11, 12. The saws 15 are mounted upon the arbor 14 so as to be individually, longitudinally adjustable thereon by means of splines 16 and spline-ways 17. The gang of saws 18 is mounted on the arbor 14 in the same way but these saws are collectively adj ustable they being integrally mounted upon a single collar 19.

The end support 11 is shaped (see Fig. 5) so that the saws 15, 18 may be put on or removed from the arbor 14 without interference therewith. It is only necessary in such case to detach the arm 142 and boX 141 from the end support 11.

Feed rolls 21 are provided and are operated from the saw arbor 14 by suitable con necting gearing 22, shown in part in Fig. 1.

Press rolls, not shown, are mounted above the feed rolls 2].. Guide rolls 23 are suitably provided at the ends of the machine.

Guides 30 for adjusting and spacing the saws longitudinally along the shaft consist of arms 31, each having at its outer end diverging branches 32, 33 extending in vertical planes, and a prop 34 extending downwardly lrom the arm 31 between the branches 32, 33. The guides 30 rest upon channel bar 35 bolted to the end supports 11, 12, and upon an angle bar 36 bolted to the front girder l3 and formed on its upper surface with ways 42, 43 which are engaged by the suitably shaped feet of branches 32, 33 of the saw guides 30. The lower end of the saw guide props 34 rest and during adjustment slide upon the upper surface of the bar 36 between the ways 42, 43.

The saw guides 30 have each at its inner end a pivoted arm 44 engaging the individual saws at its free forked end, by means of pieces 45 of wood or other friction decreasing material. The arms 44 may be swung up on their pivots to allow removal of the saws.

The saw guide 30 for the gang of saws 18 has at its inner end, as shown in Fig. 5, an

arm 441 pivoted to the arm 31 of the saw guide 30 1n a similar manner to the arms 44 engaging the individually adjusted saws 15. The arm 441 is grooved on one side for the reception and detachably bolting therein of a shank 442 integral with a collar 443 rotatably connected to the collar 19 upon which the gang of saws 18 is integrally mounted. The shank 442 extends within the periphery of the saws. This rotatable connection is shown by means of an internally projecting ring 444 on the collar 443, fitting a corresponding groove 191 in the collar 19. Suitable oiling means 445 is provided in the collal' 443.

'When the gang of saws 18 is to be removed, the shank 442 is detached from the arm 441 which is then conveniently swung up out of the way. If the individual saws 15 are to be removed, it is necessary to swing up arm 441 to clear the saws. After detaching the shank 442 from arm 441, the gang of saws 18 with the attached collar 443 can be slid oif the arbor 14, the end supporting boX 141 and arm 142 having first been removed.

The saw guides 30 are longitudinally shiftable on the edger so as to adjust the saws to positions ascertaining the distance between the saws and thus the required widths of lumber to be sawed. It becomes necessary to provide means for setting the guides to these adjusted positions. Such means as illustrated consist of the following parts. A channel bar 61 is supported longitudinally of the edger just above the saw guides and is bolted to the frame at its ends. This channel bar 61 is placed at an angle of approximately 45 degrees measured in a transverse plane, its widest outer surface facing upwardly. Upon this surface is marked or attached a scale 62 and underneath and within the channel bar 61 is formed or attached a rack 63. Upon the outer end of each of the saw guides 30 and directly over the prop 34,

is pivotally mounted in a transverse vertical plane, a holding lever 37. The outer end of the lever 37 is formed as a handle 38 and the inner end 39 curves upwardly under the channel bar 61 and is engageable with the rack 63. A coiled or other suitable spring 10 holds the lever'37 in engagement with the rack. Disengagement is effected by raising the handle 38.

The saws are manually shifted by raising handle 38 against the force of spring 10, thus disengaging the inner end 39 of lever 37 from the rack 63. While being thus held raised, the handle 38 serves as a means for longitudinally shifting the saw guides 30 together with the engaged saws 15 or gang saw collar 19 and saws 18 thereon. When the re uired position is reached, the handle 38 is aiiowed to be lowered by the spring 10 and the inner end 39 of the lever 37 engages with the rack 63, thus firmly holding the guides 30 and saws 18, 15 in the set position. Conveniently a pointer (not shown) is formed on the guide 30 adjacent the scale 62 to aid in adjusting for definite widths of lumber.

The branches 32, 33 are gabled, see Fig. 3, so as to shed sawdust and debris at the side of the ways 42, 13, Fig. 5 so that the similar branches are not prevented from coming close together in shifting the saws and guides.

Instead of the branches 32, 33 and the prop 34 of a guide 30, a single plane piece may be substituted extending preferably vertically, but in any event, downwardly so as to shed debris. This plane piece would preferably take the form of a triangle with the edges of its base resting on the ways and its apex continued upwardly for attachment of the guide arm.

In accordance with the provisions of the patent statutes, I have described the prin ciple of operation of my invention, together with the apparatuswhich I now consider to represent the best embodiment thereof; but I desire it to be understood that the apparatus shown is merely illustrative and that the invention can be carried out by other means.
