UNITED STATES PATENT OFFICE.
EDIVARD D. MACKINTOSH, OF BROOKLYN, ASSIGNOR. TO PAUL PRYIBIL, OF
NEXV YORK, N. Y.
SWING-SAW MACHINE.
SPECIFICATION forming part of Letters Patent No. 396,218, dated January 15, 1889.
I Application filed April 18, 1888. Serial No. 271,046. (No model.)
To aZZ whom it may concern.-
Be it known that I, EDWARD D. MAOKIN- TOsH, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Swing-Saw Machin es, of which the following is a specification.
This invention relates to swing-saw machines in which the saw is made to cut in a straight line or such other line as may be desired by means of a guide-rail which supports the swinging frame and controls its swinging movement, as described in Patent No. 370,962, dated October 4:, 1887. In such machine, as in all swing-saw machines, some provision is desirable for raising and lowering the swinging frame and the saw to make the saw travel on a higher or lower level. In the machine described in the aforesaid patent this raising or lowering of the frame is effected by raising or lowering the frame relatively to the guiderail, the latter remaining stationary or at a fixed level. This method of adjustment involves a deviation from the normal line of movement of the saw-shaft produced by the swinging movement of the frame.
The object of my invention is to provide for the raising and lowering of the frame and saw without any departure of the saw-shaft from the normal line of movement, except the rising and falling of said line; and to this end I provide for the adjustment of the guide-rail and the swinging frame together without the necessity of any change in their relation to each other; and myinvention consists in a combination, hereinafter described and claimed, for such an adjustment.
This invention also consists in the combination, as hereinafter described and claimed, with a swinging saw-frame and a guide-rail for controlling the swinging movement of the same, of a spring for the purpose of counterbalancing or sustaining the weight of the said saw-frame.
In theaccompanying drawings, Figure 1 is a side view of a swing-saw machine embodying my invention. Fig. 2 is a front View of the same, and Fig. 3 is a horizontal sectional view showing the adjustable guide-rail and its fixed support and means of adjustment.
Similar letters of reference designate corresponding parts in the several figures.
S S designate fixed uprights, constituting the stationary framing of the machine.
A-designates the swinging saw-frame, and B the driving-shaft upon which it swings.
D D are the fixed upright brackets, which constitute or contain the bearings in which the frame A swings, and in which the said frame and the shaft B are capable of a Vertieal movement.
0 design ates the saw-shaft, arranged in bear ings in the lower part of the swinging frame A and carrying the saw C or any rotary cutter.
B is a pulley on the driving-shaft B, from which a belt, 6, runs to a pulley, G on the shaft 0, for the purpose of driving the saw or rotary cutter.
E designates the guide-rail, attached to one of the uprights S, and F is a roller attached to one side of the frameA and running on the said guide-rail. The guide-rail, instead'of being secured directly to the post S, is made to form part of a bracket, E, which is fitted to slide on an upright dovetailed plate, G, firmly secured -to the said post, and is capable of adj ustment upward. and downward on said plate by means of a screw, H, which is fitted to turn freely but confined longitudinally in a bearing in a lug, (1, provided on the lower part of said plate, and which screws through a female screw in a lug, e, provided on the lower part of the guide-rail or bracket E.
By turning the screw H by hand the bracket and the guide-rail may be moved upward and downward, and, as the rail supports the swinging frame and the shafts B and O, the frame and the saw are raised and lowered with the guide-rail without any change in their relation, and in the swinging movement of the frame the shaft C is caused to describe the same line without regard to the height of the guide-rail or the distance of the said shaft from the saw-table.
I design ates a spiral. spring, one end of which "with; along with the said rail, the swinging frame,.and the shaft 0 and saw or cutter C, so that its pull on the saw-frame is not varied by the adjustment of the guide-rail. The said spring, which is a tension-spring acting by a pulling action, becomes more powerful as the frame moves from a vertical position, and the force required to counterbalance it is greater.
hat I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination, with the swinging and bodily rising and falling frame, the drix'ingshaft about which said frame swings, and the shaft for the saws or rotary cutter carried by said frame, of a gui ;le-rail for supportin said frame and guiding it in its swinging move- EDVARD D. MACKINTOSH.
