' To all 'w/wm z't mag concern:

Be it known that LJAMEs lllonn'rnfiny a citizen of the United States, resid ng at Gieenwich, in the county of Washington and State of New York, have invented cer-e lica tion.

This invention relatcsto saw tables or and from the saw and willbe so constructed" as to withstand hard 'usage and positively support the stock.

v A further object of tlieiinvention isto provide means upon the table whereby, the,

saw will not be exposed when ii is not acting upon stock, so that the danger of 1n ury to the operator is overcome.

The invention further seeks to provide a novel support .for a saw svliich may be v readilv connected toahportable engine and permit the saw to be operated through 25 power supplied by said engine;

The several stated objects of the in ven-' tion, and such other objects as will 1nc1- dentallyappear from the following descrip tion, are attained in mechanism of the character illustrated in the accompanying draw ings, and the invention resides in certain novel features which will be particularly pointed out in the claims following the. description. a o a In V the annexed drawings, which fully illustrate my inventionjz+Figure 1 is aside -view of the saw table and theparts for supporting the same, the figure illustrating the 1r anncr in which the device'may be attached to the engine frame; Fig; is a plan View of the improved apparatus; 3 is 'a rear end elevation with parts broken away and in section; and Fig. 4: the saw guard, v I

In carrying out my invention, I employ vside bars 1 which are intended to rest upon or project over the axle 20f the engine and be secured to the axle byclips 3 engaged ,around. the axle in the usual manner and secured to the beams, by, nuts 4, as will be readily understood. To the front ends of the side bars 1, I. secure acrossibar orplate 5 having a depending i'lange 6 which is adapted to engage a cross sill of the engine frame and thereby aid in supporting the 1 side bars upon the said engine fraineythe "caught in the belt.

and 2., bars 1' at the-rear ends thereof, I secure brackets 77 which 'areeconnected by transtain new and useful Improye nents in Saw Tables, of which the following-1s aspeciing uponfone end the saw blade indicated relati ve position of the engine and its bed being indicated dotted lines in Figs. 1.

Upon the upper sides of the side at 11in Fig. 1, and upon its other end a pulley 12which receives power from the enginethrough a belt 13, as will be readily understood. A shield 14: is secured to a lateral frame or bracket 15 carried by the adjacent'side bar 1, and this shield extends up and over the pulley so as to protect the same from falling objects and also prevent persons passing near the nachine being Upon the side bar 15 adjacent to the saw, I securebracketslfi which carry the inner guard orhousing member 17 which projcts upwardly over the sawso that persons standing or passing near the frame cannot come into contact with the saw while the same is working and be thereby -in- Ijured. It will be understood, of course,

that this guard 17 is so constructed as to inclose the saw and tov that end it will be preferably constructed of a top plate 18 and carried by the side plates. Rigidly s'ecured to the side bars 1 and extending "suitabl' curvedand side plates 19 secured downwardly and rearwardly therefrom is i a frame 20 which will preferably be constructed of angle" or channel bars connected by diagonal braces 21 and further strengthened by struts 22 extending from the lower corners of the frame to the side bars, as shown in Fig. 1. Hinge members 23 are secured to the frame 20 at the lower end thereof, and to the said hinge 'Inenr bers are pivotally connected the co-acting hinge members 2% secured to the lower ends of side bars-25 which are preferably angle iron and constitute the main support for thesawtable proper, shown at 26. The side bars or standards 25 are connected by suitsupplemental posts 28 extend between. the

able braces 27 and are secured to the table 26 near the rearedge of the same, while table, said posts 28 being connected by braces 29.

The table proper or platform is composed of parallel angle bars'31 and spaced transverse bars 32 secured to and extending.

between the same. These transverse bars 32 have convex upper surfaces, as shown at 33, so that the lumber placed upon the table may be fed over the same, to be brought into position in front of the saw, with very little friction. Between those ends of the side bars 31 which are remote from the saw, I mount a roller 34 which, by its rotation, facilitates the placing of lumber upon the table, as will be readily understood. The outer side bar 31 is coextensive inlength with the saw table, as shown most clearly in Fig. 2, but the inner side bar 31 terminates adjacent to the saw and a supplemental. side bar 35 is provided in alinement with the said inner side bar but spaced therefrom so as to provide an opening or notch through which the saw may reach the stock.

To he standard 25 nearer the saw, I secure the supplemental support 36 which is carried laterally from the standard and then upward parallel thereto, as shown most clearly in Fig. 3, so as to support the end of the saw table, a brace 30 extending between said lateral support and the front edge of the table. To the standard 25 and the said lateral support 36 Igecure an arch 37 which formsthe end ofthe saw. guard and carries a housing 38 whfih is suitably shaped to fit over the saw and of such dimensions that, when the table is swung to thesaw, it will fit over the guard 17, as shown in dotted lines in Fig. 1. This housing 38 consists of a top plate 39and side plates 40 which are secured to the top plate by arched supports 41, the central portions of said supports being secured to the top plate 39 and the end portions of the same being secured to the side plates 40. The side plates 40 are substantially triangular in shape and the bases of the triangles presented by said side plates are'constructed with flanges through which suitable bolts are passed to secure the plates to the arch 37. A reinforcing and supporting frame 451" is bolted to the ends of the bars 31 and and. extends therefrom to be secured to the lower edges of the side plates 40 and the top plates 39.

Chains or similar devices 42 are secured to the inner side bar 31 of the saw table and to the rear bar 8 so as to limit the movement of the table awayfrom the saw and thereby prevent the table assuming such a position that stock placed thereon will tend to slide t heref rom.

in proper relation to the engine to be posiin order that the saw shaft may be kept each of the side bars 1, brackets 43 in.which are adjusting bolts or tension devices 4 1. These tension devices carry nuts 45 by which they are adjustably secured in the said brackets 43, and the ends of the said bolts are flattened and provided with openings 46 whereby clips 47 may be secured thereto, the said clips passing around the axle 2, as shown clearly in Fi 1,'so that, if the belt should stretch and ail to properly engage the pulley 12, the side bars 1 may be moved longitudinally over the axle and the pulley 12 thereby set in a. position farther from the driving shaft of the engine. 49 designates braces which. may be arranged as desired between the cross bars of the table 26.

It is thought that the use and advantages of my device may be readily understood from the foregoing description taken in connection with the accompanying draw- When the lumber to be sawed 1s being placed upon the table 26, the said table rests the table is swung toward the saw so as to carry the lumber thereto, and this swinging of the table will cause the housing 38 to swing to the position shown in dotted lines in Fig.1 in which it will extend over the ard 17 and the edge of the saw will pro- ]ect through the opening of the arch 37. It

will also be readily noted that the table will assume an inclined position so that the stock will tend to gravitate toward, the saw and, consequently, it will not be necessary for the operator to approach so closely to the saw as with other devices. The swinging of the table toward the saw may be accoinplished by pushing upon the outer edge of the table, but in order to more easily accomplish the swinging of the table I provide fingers or stops 48 along the inner edge of the table against which the lumber may rest so that a push exerted through the lumber will carry the table toward the saw. These stops 48 als) serve to prevent the lumber, beyond the saw, rolling from the table when it is in the position shown in dotted lines in Fig. 1.

ify device is very simple in its construction and may be produced at a low cost. It may be applied to any portable engine and will effectually prevent injury to the operator or to any other persons who may be near the saw. Moreover, the stock will be fed to the saw easily and positively so that the labor incident to cutting up logs into lengths or dividing lumber will be minimized. The device will preferably be conan axle, and means carried by structed of angle and channel irons throughout so that it will possess the maximum strength with a minimum wei ht and may be very rapidly and, there ore, cheaply manufactured. As the device is adapted to be mounted directly upon a portable engine, it may be easily moved from place to place so that it is especially adapted for use in lumber camps.
