MICHAEL L'ALLY, NORTH LAWRENCE, OHIO, AND JOHN J. KEHOE, OF

NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 242,004, dated May 24, 1881.

Application filed February 28, 1881 T all whom it may concern Be it known that we, MICHAEL LALLY, of North Lawrence, in the county of Stark and State of Ohio, and JOHN J. KEHOE, of thecity, county, and State of New York, have invented a new and useful Improvement in Tables for \Vood-Working Machinery, of which the following is a specification. I

Our improvements relate to the tables of band,jig, and other saws, and the tables of other Wood-working machinery upon which the material is required to be moved by hand. The object of the invention is to reduce the friction in moving the material, and thereby 1 save labor and ease the saws.

In the accompanying drawings, Figure l is a vertical section of a saw-table fitted with our improvements. Fig. 2 is a vertical section at right angles to Fig. 1. Fig. 3 is a plan view of the table, and Fig. 4 represents a modification.

Similar letters of reference indicate corresponding parts.

A is a saw-table of usual construction, in the surface of which balls b are fitted in apertures a, placed at suitable distances apart, according to the character of work done on the table. The under side of the table is chamfered around the apertures to form sockets for the balls, and the apertures are of a size to allow the balls to project slightly through from the under side, the balls being thereby sustained againstthe thin edge of the aperture and the friction reduced to a minimum.

Upon the under side of the table, beneath the apertures, bars 0 are fixed, and in these bars 0 screws cl are fitted. The balls I) rest upon the ends of screws d, so that the balls are thereby sustained while being allowed to 0 turn freely. The lower ends of screws d are bent in the form of cranks, and the screws in (No model.)

line in one direction will be connected for simultaneous mor'ement to raise and lower the balls by rods 6, connected to the crank ends of the screws. With this construction the balls 5 can be raised to project as desired through the surface of the table, and will thereby support material placed on the table, so that such ma tcrial can be readiiy moved as required in the progress of the work. When not required the 0 balls can be lowered by turning the screws.

In Fig. 4 the balls I) are shown fitted in cups g, that are fitted in apertures of the table for vertical movement in guides f by means of screws. a.

Instead of being fitted in the saw-table, the balls may be fitted in a separate piece adapted for placing on the table, so as to save cutting the table.

The invention can be applied to the tables of circular, jig, and band saws, planing-machines, and other wood-working machinery. With the improvement heavy materials can be readily manipulated, thereby saving labor, and by relieving the saws and other tools of friction and strain breakage is prevented.

Having thus described our invention, we claim as new and desire to secure by Letters Patent A saw-table having apertures a on the under side, the bars 0, the screws d, cranked at the lower ends, the rods 6, and the ball-carrying cups g, movable in guides f, as shown and de scribed.
