BENJAMIN G. LUTHER, OF ORCESTER, MASSACHUSETTS.
SAWING AND MlTERING MACHINE.
SPEOIFISATION forming part of Letters Patent No. 553,009, dated January 14, 1896.
Application filed April 4,1 8 9 5.
To all whom it may concern:
Be it known that I, BENJAMIN G. LUTHER, a citizen of the United States, residing at Vorcester, in the State of Massachusetts, have invented a new and useful Improvement in Sawing and Mitering Machines, of which the following is a specification.
The object of my invention is to provide a conveniently-operated machine for sawing off or mitering both ends of a narrow board or strip at the same time, and it consists in the improved construction and arrangement of the adjustable heads for holding the saws, and in the combination of the saw-arbor pulley with idler-pulleys for guiding the belt, as hereinafter fully set forth.
In the accompanying drawings, Figure 1 represents a front elevation, showing the saws set at right angles with the bed. Fig. 2 represents a top view of the machine, with the saws set at an angle of forty-five degrees, for sawing the ends at a miter. Fig. 3 represents a rear elevation with the saws set at right angles with the bed, as in Fig. 1. Fig. at represents an end elevation. Fig. 5 represents a transverse vertical section taken in the line 5 5 of Fig. 1.
In the drawings, A represents the bed of the machine, and B the drivingshaft, upon which are secured the drums G G for driving the saws D D, the said saws being supported for revolution by means of the adjustable heads E E, provided with the bearing-boxes a a for the saw-arbor.
The head E is provided with the base I) and is pivoted by means of the bolt 0 to the sliding plate F, which fits the beveled edges of the bed A of the machine, and the head E is adjusted at any required angle relatively to the axis of the bed A by means of the circular slot d in the base I) and the clampingscrew e, which is connected with the sliding plate F.
The saw D is driven from the drum 0 by means of a belt m, (shown by dotted line in Fig. 5,) and in order to provide for the proper running of the said belt over the pulley Gon the saw-arbor H at any desired inclination of the saw I provide an idler-pulley I, which turns loosely upon a stationary rod f, the said rod extending through the ears 9 g, which project from the base-plate J, the said plate $erial No. 544,469. (No model.)
being pivoted to the web h of the head E at the bolt 1', the said plate J being made adjustable upon its pivot-bolt by means of the curved slots j j and the tightening-screws kk, whereby the axis of the idler-pulley I may be set at any desired inclination in a vertical plane to cause the proper running of the belt upon the pulley Gwhen the head E is set at an inclination with the axis of the bed A of the machine.
To the projecting outer ends of the rod f, upon which the idler-pulley I revolves, is socured the hanger K, having a lower curved portion at provided at its opposite ends with the arms 0 0, by means of which the required connection is made with the rod f, and between the arms 0 0 is placed the idler-pulley L, which turns loosely upon a fixed rod 19 held by the said arms, and the idler-pulley L is rendered adjustable about the axis of the pivoting-rod fby means of the curved bar g, which passes through an opening 7; in the Web h of the head E and is jointed to the hanger K at the point it and provided with the perforations q and adapted for the entrance of a pin '1', which by resting against the outer side of the plate J will hold the pivoted hanger K at any desired downward inclination upon the pivot-rod f, and the outward movement of the idler-pulley L serves to properly tighten the belt m.
At the opposite ends of the bed A of the machine are placed the upright sliding bars M M, adapted to slide in the boxes N N, the said sliding bars being connected at their upper ends by means of the angular bar 0, to which the adjustable sliding rests P P are attached, the said rests being secured in their proper positions on the bar 0 by means of the screws 3. The projecting forward edge t of the rest P is cut at an angle of forty-five degrees, and the upper surface of the said rest is provided with the groove u, made parallel with the edge 6, and to the rest P is secured the adjustable back gage Q, provided with a slot 0, extending parallel with the groove it in the rest 1?, and a tongue w, which enters the groove to and serves to preserve the proper parallelism of the face a: of the gage Q with the axis of the bed A, the said gage being secured in proper position by means of the thumb-screw 1 which is held in the slot '21.
The bar 0, to which the rests P P are attached, is operated up and down by means of the hand-operated arm B, which is secured to the rock-shaft S, the outer ends of the said rockshaft being provided with the weighted arms T T, by means of which the weight of the sliding bars M M and thebar O is counterbalanced, the inner ends of the said weighted arms being provided with the segments U, from the upper edges of which connection is made with the projecting arms .2 at the bottom of the bars M M by means of the straps to and the links D, so that the upward or downward movement of the segments U of the arms T T will cause a corresponding upward or downward movement of the bar 0 and the adjustable rests P P attached thereto. The bed A is provided with a longitudinal slot 0 for the passage of the belt m and the base I) of the head E is provided with the curved slot 0 a slot 0 being also made in the sliding plate F upon which the head E rests, so that the belt may have a free downward passage to the forward side of the drum 0.
The heads E are made adj ustable upon the bed A by means of the rack d at the under side of the flange e of the bed A, which rack is engaged by a pinion f at the inner end of a short shaft g, to the squared outer end of which is fitted a hand-crank 7L, and the heads E are retained in their set position on the bed A by means of the tightening-gib i, which is actuated to clamp the sliding plate F to the bed A by means of the screws In operating the machine with the saws D D set to cut a miter, as shown in Fig. 2, several strips may be piled upon the rests P P, with their rear edges resting against the back gages Q, the rests P P being normally held at their elevated position by means of the weights V upon the arms T. Then by carrying the hand-lever R forward toward the bed A of the machine the bar 0 will be caused to move downward, so that the strips upon the rests P P will come in contact with the saws and be cut at both ends at the proper angle. and upon the completion of the cutting the backward movement of the hand-lever R will cause the elevation of the rests P P, so as to remove the niitered strips from the saws, the
work being thus done with great rapidity and economy.
I claim as my invention 1. The combination with the sliding plate, and the saw head pivoted to the sliding plate and adjustable at any required angle therewith, with the adjustable plate pivoted to the adjustable saw head, and the idler pulley held by the adjustable plate, whereby the axis of the idler pulley may be set at any desired inclination in a vertical plane, to cause the proper running of the belt upon the idler pulley when the saw head is set at an angle with the sliding bed, substantially as described.
2. The combination of the sliding plate, and the saw head pivoted to the sliding plate and adjustable at any required angle therewith. with the adjustable plate pivoted to the saw head, the idler pulley held by the adjustable plate, the pivoted hanger carried by the said plate, the idler pulley held by the hanger, and means for changing the inclination of the hanger relatively to the adjustable plate, substantially as described.
3. The combination of the saw heads, made adjustable toward and from each other, and adapted for pivotal movement to the desired angular position, with the bar adapted for up and down movement, the adjustable angular rests arranged upon the bar, and the back gages adapted for angular adjustment upon the rests, substantially as described.
BENJAMIN G. LUTHER.
