IMPROVEMENT IN' CIRCULAR-SAW MILLS.

The Schedulerel'erred to in thele Letters Patent and making part of the same.

To all whom yit may concern:

Beit known that LPETER N EEB, ofthe. city of Buffalo, in the county oi'Erie, in the State 'of New York, have invented a new and improved Mode of Constructing and operating Circular-Saw Tables; and I do hereby declare that the-following is a full, and ex- .act description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon. The nature of my invention consists in providing a circular-saw with two independent sliding and adjust' able tables sin-arranged that the circular-saw may run iu between them; these tables may either be permanently secured to the main frame of the saw, or may be detachable therefrom.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l is a perspective view of one ofthe sliding saw-tables.v

Figure 2 is a plan viewof two sliding saw-tables.

A is the main frame of the sliding tables.

A' A' are the frames of sliding tables B B.

The same are provided each with tvfo segments D Said segments, in conjunction with pinious E E, have for their purpose the-raising oradj listing of frame A' to any desired angle.

Frame A is secured to the main frame A by means of hinge-joints, as plainly seen in iig. 1.

B B are two sliding tables; theyare slidiugin frames A' A,and are provided each with an adjustable gauge,

C. The works that are to be sawed are to .be put against said gauges, andthe sliding tables are to be pushed toward the saw in order to make the saw cnt.

It will be observed that in providing a circular-saw with twotables on the plan of g. 2, the operatorie enabled to saw always with the grain of the wood, which,`under circumstances, is of much importance; for instance,in sawing picture frames or gilt moldings, if sawed against the grain the wood is apt to break out onthe edges ;v (i e., one end is to be sawed on one table and the other end is to be sawed on the other table; both gauges are to beset at corresponding anles.)

g D D are two segments secured to frame A1, (see iig. 1;) they are operated by means of shaft E1 and piuions E E, the purpose of which have been hereto fore described.

F F are two screw-bolts, (one for each segment;) they have for their object to secure or to prevent the segments from slippiugwhenever the frame A' is raised by tightening up said bolts, so that their heads Witnesses:
