MACHINE-TABLE.

SPECIFICATION. forming part of Letters Patent No. 299,697, dated June 3, 1884.

Application filed September 7, 1E3. (No model.)

To all whom it may concern:

Beit known that I, JOHN J. SULLIVAN, of Green Point, in the county of Kings and State of New York, have invented a new and useful Improvement in Receiving-Tables for Saw-Ta bles, of which the following is a specification.

In sawing box-boards to reduce them to uniform sizes for box-making and other purposes7 a boy is usually employed to stand at the back of each saw-table to draw forwardthe boards as they leave the saw and to pile them up. The services of the boy are necessary to prevent the pieces of board frombeing thrown back by the rapidly-rotating saw, and thus injuring, orperhaps killing, the Sawyer, and also to pile up and take away the sawed boards.

The obj ect of my invention is to dispense with the services of a boy at each saw-table.

' To this end the invention consists in the combination, with a circular-saw table, of a pair of holding and drawing rolls, which are adapted to grasp a board before it leaves the saw and to draw it forward, a rising and falling receiving-table arranged at the end of the saw-table, a counterbalance-weight connected with the said receiving-table, and a number or series of supplemental weights, which are arranged to be picked up by the ascending counterbalanceweight as the receiving-table descends by the increasing weight of boards received upon it.

The invention also consists in novel combinations of parts, hereinafter described, and referred to in the claims.

In the accompanying drawings, Figure l is a vertical section of a portion of a circularsaw table and a receiving apparatus embodying my invention, the receiving-table being in its highest position. Fig. 2 is a rear view of the apparatus, with the receiving-table in the same position as in Fig. l; and Fig. 3 is a vertical section similar to Fig. l, except that the receiving-table is loaded and in a depressed position.

Similar letters of reference designate corresponding parts in all the figures. A designates the saw-table, and B the saw Working therein and rotated by a belt, B. At the end of the saw-table A are standards or frames C, which at their upper ends carry the bearings for a pair of holding and drawing 5o rolls, D D, which are geared together by pinions a, and one of which carries a pulley, b, which receives a driving-belt, b. g

E designates the receiving-table proper,

which is arranged at the end of the sawtable 55v A and beyond the rolls D. The said receiving-table E is secured on a supporting-frame,

E', which is between the standards C, and is fitted to guides d on the inner sides of the standards. The said frame LE has a down- 6o wardly-projecting rod, FP, working through a stationary guide, e, at the base of the machine. The severa-l guides described serve to main-` tain the table E in a horizontal position as it rises and falls. To the frame E of the table E is connected a cord, chain, yor like device,

f, ,which is carried upward over a pulley, g, and thence downward to a counterbalancing- Weight, F, which is guided in standards or posts G, and which is heavy enough to main- 7o tain the table E in the elevated position shown in Figs. 1 and 2 when no weight is on it.

F F2 designate supplemental weights, which rest in supports h, attached to the standards G, and at different heights. ber of these supplemental weights, supported at different heights, may be employed, and they will be picked up, one after the other, by the main weight F as it ascends. Before the boards or pieces H leave the saw the rolls D 8o grasp them and draw them forward onto the receiving-table E, and after three or four or more have accumulated thereon the receivingtable descends.' As the weight of boards on the receiving table increases, the weight F first 8 5 picks up the supplemental weight F', and afterward the second weight, F2, and so on with the Y other weights, if others be used. From time to time the pile of boards is taken from the receiving-table, and the latter then rises t0 its 9o original position. The rolls -D prevent the boards Aor pieces from being thrown-back by the rapidly-rotating saw as they leave the saw, and while the sawyer is presenting or moving another board against the saw. 95

I do not claim, broadly, the rolls D in com bination with a saw, but only desire to include in my invention the combination of the said Any desired numy y rolls with the rising and falling receiving-table and with the saw-table.

YVhat I claim as niy invention, and desire to secure by Letters Patent, is-

l. The combination, with a circular-saw table, of a pair of holding` and drawing rolls which are adapted to grasp a board before it leaves the saw and to draw it forward, a rising and falling receiving-table arranged at the end of the saw-table, a counterbalance-Weight connected with the said reccivingtable, and a number or series of supplemental weights which are arranged to be picked up by the ascending eounterbalance-wcight as the receiving table descends by the increasing Wcight of boards received upon it, substantially as and for the purpose herein described.

2. The combination of the saw or other table', A, the standards C, the receiving-table E, fitting between and guided by the standards C, the counterbalancing-weight F, connected Wit-l1 said receiving-table, one or more supplemental weights, and supports h for the supplemental Weights, at dii'ercnt heights, substantially as and for the purpose described.
