' Memphis, in the county 0f Shelby and State 0f Tennessee, have inventedv certain new and useful Improvements in Self-Feeding RipvSawing Machines; and I do 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, reference being had to the accompanying drawings, and to letters of reference marked Ithereon, which form a part of thisspeciication.

Figure l of the drawings is a perspective View. Fig. 2 is'a verticallongitudinal section, and Figs. 3, 4, and 5 are detail views.'

Fig. 6 is a detail View showing more fully the hinging or pivoting connection between the pivoted frame and the work-table.

This invention pertains to certain improvements in saw feed mechanism; and it consists of the novel combination and construction of parts, as wil-l fully appear from the following description and accompanying illustration.

In accordance with my invention I employ a suitable supporting-frame A, upon which is mounted a table A', having its outer end hinged to said frame. Directly under its opposite end is arranged an adjusting device 13,to effect the vertical adjustment of the table at any desired angle of inclination required. This adjusting device consists of a shaft a, extending entirely across and journaled in the frame A, and having cam-arms a a', engaging the under side of the table A', 'said arms, however, when in their lowest position. or outof use, resting in gains or notches a2 a2 in the top edge of one end of the frame A. The outer end of the shaft a has preferably formed with it ahandle awhich is pivoted to a slotted slide a4 to limit the movement of the handle and consequently that of the shaft d and its arms a d in their upward direction.

The slotted slide a engages a stop or stud a5, projecting from the frame A and through its slot, so that while it allows the slide a certain amount of play, according to the predetermined movement of the handle or shaft, yet it limits the movement of the slide.

C is the work-feed device, which is arranged above the table A', and" comprises a frame or' support c, hinged or pivoted to a fixed hori-k zontal arm c of a standard c2, bolted to the vtop edge of the frame A and extending up through a recess or opening c3 in the oppositej edge of the table. The hinging or pivoting of the frame c to the arm c of the standard c2 is effected by means of a rod c3, (also, asv presently seen, serving as a shaft,) passed lthrough apertures of lugs c4 on said arm and .on the inner cross-bar of said frame. Oil

or lubricant boxes c5 may be furnished upon the lugs c4 to lubricate the bearings of the shaft or rod c3. In the hinged or pivoted frame b is journaled a shaft d, extending lengthwise of the table A and carrying atl one end a beveled pinion cl', gearing with a similar pinion d2 on a shaft d5, bearing a spur-wheel or feeder proper d4, which engages and feeds the work forward to the saw. The opposite or inner end of the shaft d is also provided with a beveled pinion d5, which gears with a similar pinion d on the rod or shaft c3. The shaft d may also be lubricated by means of lubricant or oil contained in boxes e e, arranged upon cross-pieces of the frame b above the bearing of said shaft. Upon one end of the shaft or rod c3 is secured a pulley f, which is driven by an endless belt f', also encompassing' a small pulley f2 on a shaft g, suit-ably journaled in a frame A. From the fixed armlc of the standard projects forward an offset arm c6, which carries at its outer free end a swiveled or pivoted nut c7, engaged by a screw e8, also engaging the inner end of a spring c9 of the frame b of the work-feed device C. One end of the screw c8 has a crank or handle 010 for its con# venient manipulation, by turning which in the required direction the hinged or pivoted frame b of the feed device C is depressed and the spur-'wheel d caused to engage and feed, through its rotation, the work to the saw. The feed device may, when not in use, be swung to one side by suitably loosening the fastening of the fixed arm -c from its support c.

D is the saw, arranged as usual to project up through the table A, and having its mandrel or shaft`D suitably journaled in the frame A, and having a driving-pulley D2.

IOO

The shaft or mandrel D bears a cone ot' three or more pulleys dx, any one of which is encompassed by an endless belt CZXX, likewise encompassing a similar cone of pulleys (ZXXX on the shaft g.

E is a Work-guide arranged on the table A', parallel with the saw D and extending the entire length of the table, its ends beingprovided with screw-threaded loops or eyes h, depending therefrom at the ends of the table.

F is a shaft arranged and journaled upon one side of the table A', and carrying' at one end a beveled pinion t', geared to a similar pinion t" on a shaft G, journaled upon one end of the table A and engaging one of the eyes or loops 7L of the Work-guide E. Upon the shaft F, near its opposite end, is aseeond beveled pinion il, geared to a similar pinion ai* on a shaft- G, journaled upon that end of the table A and engaging the 4other eye or loop h of the work-guide E, while upon this end of the shaft G' 1s a handle or crank j, for the convenient manipulation thereof, whereby the work-guide can be adjusted relatively to the saw according to the predetermined width of board required.

The Work-guide E is provided with an up.

wardly-extending arm or index k, registering with a suitable scale or numbered graduations Z, carried by the arm C as a con venient means of support.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with the table and its supporting-frame, of the standard fixed to said table, and it-s horizontal arm arranged above the table, and the hinged or pivoted frame or support supporting the workfeed mechanism, comprising the geared shafts, one actuating the feeder proper and one being driven as shown, said feed proper consisting of a shaft arranged at right angles to the former shaft and carrying a toothed or spur `wheel, and means to hold said hinged or pivoted frame depressed, causing feeding contact between said wheel and the work, sub--
