CUMMINGS, OF NEW YORK, N. Y.

STONE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 732,986, dated July 7, 1903.

' Application filed May 10, 1902. Serial No. 106,749. (No model.)

T (ZZZ whom it may concern:

Be it known that 1, JOHN P. WINTER, a

citizen of the United States, residing at City Island, in thecity and county of New York and State of New York, haveinvented certain new and useful Improvements in Stone-Sawing Machines, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertain's to make and use the same.

The object of this invention is to provide improved means for operating the saw-sash of a stone-sawing machine of the kind and class described and claimed in United States Letters Patent No. 601,789, granted to H. H.

Cummings, April 5, 1898; and the invention consists in the simple and efiective means for operating the sawsash shown and described ing drawings form a part, in which the separate parts of my improvement are designated by the same reference characters in each the views, and in which- Figure 1 is a side view of a part of the frame of a stone-sawing machine and showing my improved means for operating the sawsash, part of the construction being shown in section; Fig. 2, a plan view thereof, and Fig.

3 section on the line 3 3 of Fig. 1.

' In the drawings forming part of this specification I have shown a part of the main frame of a stone-sawing machine, such as is described and claimed in the United States patenthereinbefore referred to, and this frame, as shown, comprises bed-sills a, upright members a ,and horizontal members (1 and in the practice of my invention I mount in or on the horizontal members a a crank-shaft b, one end of which is provided withfa powerwheel I) and the'other with a fly-wheel b Connected with the upright members a of the main frame or support in any desired manner or supported in connection with said main frame are bearings 0, through which are passed transversely-arranged and parallel shafts c and the upper shaft 0 supports a .b, which are connected with the crank-shaft b, as clearly shown.

The upper end of the lever c is pivotally connected at c with a rod f, and the lower end of the lever c is pivotally connected at g with a rod h, and the rods f and h are piv otally connected at f and h with a verticallyarranged bar 7), which is preferably composed of angle-iron and the lower end of which is preferably provided with a shoe or support i which rests upon a support 2' in the bottom of the main frame of the apparatus, and be tween the shoe or support '6 and the support i are preferably placed ball-bearings i By means of this construction the .bar 5 will be given a forward-and-backward movement when the crank-shaft b is turned, and the saw-sashj is connected with this ban-as shown at j and this connection at 7' is vertically movable on the bar '6, and a connecting member 9' iscoupled to the bar t' by means of bearingplates j which grasp the flanges j" on the bar 1' and are vertically movable thereon, and in practice the saw-sash j is made vertically movable in the usual manner by means of gang-screws or in any preferred way. The oscillatory or backward-and-for- Ward movement of the bar t' occasioned by the crank-shaft b and intermediate connections operates the saw-sashj in the usual manner, and it will be understood that this sawsash is mounted in a suitable frame, such as is shown and described in the patent referred to, and the bar i may also have suitable guides, if necessary.

My invention is not limited to the construction of the saw-sash nor to the method of raising and lowering the same; but said invention is limited to the meansherein described for operating said saw-sash, and said means may be applied to the construction shown in the patent hereinbefore referred to or to any other form of a stone-sawing machine.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In astone-sawing machine, a frame, a'crankthe adjacent ends of said levers, substantially shaft mounted therein, a vertically-arranged as shown and described. saw-sash-operating bar unconnectedwith the In testimony that I claim the foregoing as frame, a support between said bar and said my invention I have signed my name, in pres- 5 shaft, verticallyarranged levers connected ence of the subscribing witnesses, this 8th 15 with said support and arranged one above anday of May, 1902.
