dated July 3, 1900.
App1imi0n1anovemta9,1899. serianafzsaize. einmal.)
To @ZZ whom it may concern: i
Be it known that l, CHARLES L. SHQNLE, a citizen of the United States, residing atTuscola, in the county of Douglas and State of Illinois, have invented new and luseful Improvements in Metal Bench-Saws, of which the following is a specification.
My invention relates metal bench-saws, and pertains to a saw supported in guideways upon a base, the said base constructed to clamp and hold the piece of metal being sawed at any desired angle and also provided with means for measuring the length ot' the piece to be sawed and by which means pieces of uniform lengths can also be sawed, all of which will be fully described hereinafter and particularly pointed out in the claims.
In theaccompanying drawings, Figure l is a perspective View of a machine embodying my invention. Fig. 2 is avertical sectional view on line 2 2 of Fig. 1. Fig. 3 is-an inverted plan view. Fig. 4 is a detail view of one of the base-clamping blocks. Fig. 5 is an enlarged sectional view on the line 5 5 of Fig. 1. Fig. 6 is a horizontal sectional view on the line 6 6 of Fig. l. Fig. 7 is a horizontal sectional view on line 7 of Fig. l. Fig. S is a section al View at right angles to Fig. 7.
Referring now tothe drawings, A is a base having at its under side and preferably at its corners the depending legs or projections B, by means 'of which the base is supported and by means of which the base can be screwed or otherwise suitably attached to a bench. Projecting from opposite sides of the base A and near one edge thereof are'the standards C, the standards being connected at their upper ends by a cross-bar D. The upper portions of the standards C are provided with longitudinally-extending centrally-arranged slots a and at the inner and outers sides with the longitudinally-extending grooves l).
E is a saw-supporting track or way, which is provided with a horizontal slot f, and at each side of this horizontal slot are provided the horizontal grooves c, which face in opposite directions, the track or way E serving to support the saw in a manner which will be presently described. The ends of the track E lit in the inner groove?) of the standards C, and said track is provided at each end with to improvements in outwardly-projecting studs d, towhich studs are attached thesliding plates e, the attachment vpreferably being by meansof screws. By this construction thetrackorway E readily moves up and down in the standards C and the track is held against any lateral play for the purpose of more firmly and accurately holding the saw, which is attached and carried by the track or way Ein a manner which I will now explain.
Secured to one end of the track E (preferably'the left-hand end of Fig. l) by means of a pin 26 or otherwise is a block 25, the said block adapted to receive a screw 26', and upon this screw is situated a sleeve 27, which in effect constitutes a roller.
The saw consists of a U-shaped frame, of which J is the back and K and L the two depending parallel arms, the handle M being connected with the arm L. The back J of the saw is provided with `28,which receives the sleeve or roller 27, upon which sleeve or roller one end of the back of the saw is supported and reciprocated. The
opposite end of the saw is supported by means of' a block I-I, which is attached thereto by means of a screw 30, as here shown, or the block may be otherwise attached or made integral with the back, andattached to the opposite side of this block'is a sliding plate t', fitting and sliding in one of `the longitudinal grooves c of the track or way E,and connected with this block is another sliding plate j, fitting in the other groove c in the opposite side of the track or way. This plate j maybe attached to the back J by means of screws Zr, as here shown, or in any other desired manner. By means of an attachment of this character the saw is held against any lateral movement and is thus guided accurately in the sawing operation and yet permitted to freely move up and down as is necessary. The horizontal elongated bearing for the saw provided bythe plates and j serves to hold the saw-frame,and consequently the saw, against any lateral movement, as will be readily understood.
The saw 35 has one end attached by means of anadjustable bolt, which is provided at its inner end with the ears p and at its outer end with a screw-threaded stem y and ina square portion w,
termediate its ends with a longitudinal slot IOO passing through a correspondinglyshaped opening N in the arm L. The screw-threaded end y receives a thumb-screw z, by means of which the saw is readily tightened within the frame.
The means for attaching the saw is so constructed that the saw can be readily removed for the purpose of inserting another, according to the character of work it is desired to perform. This construction, whereby the saw can be readily attached and detached, consists of an endwise spring-actuated pin having a stem portion s and a larger end t. One of the ears p is provided with an opening q, adapted to receive the stem s of the pin, and the other ear is provided with an opening o" of a size adapted to receive the larger end t. Situated between the head o and the adjacent ear p is a spring u, serving to hold the pin normally in the position shown in Fig. 7. The arm K at the opposite end of the saw is provided with arms O and a springactuated pin constructed exactly the same as that described of Fig. 7, and each end of the saw is provided with an opening 2, into which a slot 3 extends. The slot is smaller than the opening 2, whereby the headt when engaging the opening 2 will hold the saw firmly in position; but when the spring-pin is pressed inward against the tension of the spring tt the small stem portion s is brought within the opening 2, and the stem portion will freely pass through the slot 3 of the saw, thus permitting the saw to be readily removed and attached by simply the pressure upon the spring-pins at each end of the saw-frame, as will be readily understood.
For the purpose of supporting the saw in an elevated position, as shown in Fig. 1, while the work to be sawed is being adjusted upon the base, the track E is provided with alatch I, having a shoulder m, adapted to engage the upper side of the cross bar D, and the track is readily lifted in this position by means of a projecting ear G, and situated between this projecting ear G and the adjacent end of the latch I is a spring n, serving to hold the latch normallyin engagement with the cross-bar D when the track, and consequently the saw, is elevated, as shown in Figs. 1 and 2. This arrangement enables the quick manipulation of the saw for either supporting it or releasing it for operation when the work has been properly adj usted. v
It is desirable to provide means for holding the metal to be sawed at any desired angle, and for this I provide by means of adjustable blocks P and S. The block P is provided with a perforated ear Q, through which a clamping-screw R passes and by means of which the block can be adjusted to any desired angle and held in its adjusted position. The block S is held in its adjusted position by means of the clamping-nut V, which screws upon the screw-threaded end U of a block T, the screw-threaded portion passing through a transverse slot W in the base A. The head or block T is provided with a Ascrew-threaded opening through which a screw-threaded rod 4 passes,the screw-threaded rod and the block T being situated beneath the base A, as clearly shown. One end of the rod 4: projects beyond the base and is provided with an operating-handle 36 and with two separated lian ges 37, between which a projection 38 of the base rests. By means of this construction the block T can be moved in either direction across the base, as will be readily understood, and can be turned to any desired angle and then clamped in the adjusted position by means of the nut V. It is also desirable to clamp the metal being sawed after the blocks P and S have been adjusted for holding it in the desired position, and this is provided for through the medium of an Lr shaped arm 6, carrying at its upper end a clamping-rod 7, adapted to be moved downward in contact with the piece of metal to be sawed. The lower end of this arm 6 is provided with a shoulder S above the base, a shoulder 9 below the base, and a reduced portion 10, which moves in a cam-groove 5, formed in the base. Communicating with the slot 5 is an opening 11 of a size adapted to permit the passage therethrough of the flange or head 9, and therefore theready removal or attachment of the clamping-arm 6, as may be desired. The object in making the slot 5 curved is to bring the clampingarm nearer to the saw when it is desired to clamp a small flat piece of metal to thebase. The base Ais provided with the transverse groove 40, which the saw will enter afterhaving passed through the object being sawed and by means of which the object can be sawed entirely in two without bringing the saw in contact with the base.
For the purpose of enabling the operator to cut o a predetermined length of metal and also for the purpose of enabling the operator to cut off a number of pieces of uniform lengths I provide the base with the rules 12, which are situated at the under side thereof, the inner ends of the rules being connected with a block 16, having a screwthreaded perforation through which a screwthreaded rod 15 passes. One end of this screw-threaded rod is provided with a vhandle 19, by means of which it is readily rotated in either direction, and adjacent this handle 19 the rod is provided with two separated iianges 17, between which a depending ear 18 from the base extends, the opposite end of the rod being supported by a suitable bearing 20. By means of this construction the rules are moved back and forth to the desired adjustment, and the adjacent edges of the base are provided with openings 41, extending to or adjacent the groove 40 therein and by means of which the operator is enabled to accurately measure the length of the article to be out. The outer ends of these rules are provided with hinged stops 13, held by means of clamping-braces 14, so that the IOO IIO
stops when turned upward in the position shown in solid lines will serve as stops against which the end of the article to be sawed will abut, and when it is desired to move the rules under the base A the stops are turned downward into the position shown in dotted lines. i
By means of a construction as herein shown and described I am enabled to support the saw steadily and firmly against lateral movement, thus assuring accurate work, and am also enabled to measure the length of the article to be cut, to cut pieces of uniform lengths, and to clamp and support the object to be sawed at any desired angle to the saw.
