THOMAS HOL'I, OF BROOKLYN, NEW YORK, ASSIGNOR TO HIM- SELF AND ABRAM T. MERWIN,
OF SAME PLACE.
Latas Patent No. 91,635, am@ June 22, 1869.`
' IMPROVEMENT IN GROOVINGMACHINE.
The ScheduleA referred to in these Letters Patent and making part of the same.
To vall whom 'it 'may concer-n:
Be-it known that I, THOMAS Hom, of Brooklyn,
in the county of Kings, andy State of .New York, have It consists in the combination and rarrangement of parts hereinafter described. V
Figure 1 represents a front elevation of my improved machine; ,V
Figure 2 represents a plan view; and
Figure 3 represents a side elevation of the same.
'Similar letters of reference indicate corresponding parts. v
A represents the table of the machine, over which the boards or other articles to be grooved are fed by the feeding-rollers, the rollers by any competent power.
O represents a rotary tool-stock, carrying saws D at each end for cutting the necessary kefs for channelling outthe grooves.
It also carries `a planing or channelling-tool, E, for removing the substance between the saw-kerfs.
The said stock C is joumalled upon slides F, arranged to slide in the adjustable ways, and provided with a handle, H, for moving the slides back and forth to traverse the board being growled, which is fed under the tools intermittinglyby the roller B, as above described.
Motion is communicated to the tools by a belt, I, from an overhead shaft and pulley I,supported in the arms K, jointed to standard L, and to which arms N, pivted to the shaft of the tool-stock, are also jointed, at v A- pulley, I2, is supported in the standards L, deriving inotion from apnlley, Q, on the main drivingshaft, by belts passing around the guide-.pulleys R R', and communicating motion to the pulley I" by the belt I Thes'aidguide-pulleysl R R are arranged upon astandard capable of adjustment around the 'axis of the driving-shaft.
. The ways G are hinged at G', and the standards L are pivctcd at L', for the purpose of adjusting the ways to thedesire angle on the board, and for maintaining being-moved by hand or the drivingbelts and pulleys in their proper workingrelations.
The bolts T, working in the curved slots T', are for securing the ways in any required position; and ad-.
justal'ile stops U are provided in thcvouter ends of the ways for governing the outward movement of the slides when it is designed to cut the grooves only partly across the board.
Wrepresents a spring-gauge or stop, arranged upon a swinging arm, W', to be employed for catching into the formed grooves, as the board ismoved along, when a number of4 grooves is tobe formed at regular intervals,- to'arrest and hold the boards. It also serves to determine the distance required between each groove, and is arranged to be adjusted to any distance from the grooving-tools. V i
I propose to arrange one of these stops on each side of the swinging frame or ways G.
X represents'a screw-clamp, designed for screwing down upon the boards when desired for holding them more rmly.
In grooving stair-stringers, which have two grooves converging at a given point, and running in opposite directions on the board, the ways G are iirst adj usted for cutting the grooves in one direction, and the board is Ipassed through, receiving all the grooves in that direction. Ihe ways are then adjusted to the other direction, forthe other groove, and the work proceeded withy as before. f
vHoles may be bored at the pointof intersection of the grooves, to give any desired form thereto, as in the ordinary method of forming such grooves by hand.
Having thus described my invention,
I claim as new, and desire to secure by Letters Patent- 1. The oscillating standard L, arms K N, carrying the pulleys Il I", and the slides F, for carrying the cutter, in combination with the swinging frame, all ari vranged and operating as described, for the purpose .specied 2. The adjustable standard and guide-pulleys R B', in combination with the oscillating standard L, pulley I2, main driving-belt, and the driving-pulley Q, all arranged and operating as described, for the purpose specified.
'Ihe above specication of my invention signed by me, this 28th day of December, 1869.
