UNITED STATES PATENT OFFICE.
GEORGE w. EUGBEE, OE CINCINNATI, OHIO, AssIGNoE To J. A. EAY a co.,
or SAME PLAGE.
IMPROVEMENT IN GAMING-MACHINES.
Specification forming part cf Letters Patent No. 46,649, dated January 720, 1874 application filed November 22, 1873'.
To all whom vit may concern:
Beit known that I, GEORGE W. BUGBEE, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Gaining-llIacl'line, of which the following is a specification:
This is an improved device for cutting' gains, notches, relishes,i or rabbets in sills, bolsters, and like pieces of timber, and consists essentially of a carriage bearing a vertically-adinstable head, having a rotary cutter, which is capable of operatin g uniformly in both the forward and backward strokes of the carriage; and my invention comprises devices for the automatic forward and backward traverse of the carriage and complete self-actin g arrest of the same at the end of every stroke, while, at the same time, the operator is enabled to arrest or reverse the stroke at any point.
In the accompanying drawings, Figure 1 is a side elevation; Fig. 2, alongitudinal section. Fig.3 is a section at the line X X, Fig. 2. Fig. 4 is a front elevation with a part of the timbercarriage in section. Fig. 5 is an enlarged section at the line Y Y, Fig. 4. Fig. 6 is an enlarged section, showing the manner of fitting the bits into the cutter-head. l
A is a base or pedestal, which may be a single hollow casting, as represented, and is surmounted by ways c for a carriage, B, which contains the principal operative parts, and is preferably a casting in the form of an inverted trough or trunk, as represented. Said carriage terminates in front in vertical ways, b, for an adjustable head, C, in whose lower portion is journaled, horizontally, the shaft D of a rotary cutter, E said shaft having at its extremity, remote from the cutter, a pulley, F. G is a spring, which balances the cross-head so as to cause an automatic elevation of the same, and connects, by rod H, with a lever, I, to which and to a nut, J, it is coupled by a pivot, K, Fig. 5. Except when rigidly iiXed naled in the head C, and is surmounted by a handle, M, by means of which the screw may be rotated to right or left, and thus vary the form depth of cut, I provide one or more cus` tomary or other suitable stops, N N', which enter sockets 0, and are furnished with screwclamps P, whose nuts p, being screwed fast, operate to hold the head to any elevation. An axle, It, fixed transversely in the carriage, has loosely journaled upon it three pulleys, S Sl T, of equal diameter, of which the pulleys Sand S are separately connected, by gearing U, with a pinion, V, which meshes in a sta tionary rack, Q. lV is a customary belt-shifter. X is a belt operated from counter-shaft Y, journaled in the rear end of the carriage. The geared connection U is such that the carriage receives a forward or a backward impulse, or is brought to rest, according as the belt is shifted to pulleys S, S', or T. Each forward and backward stroke is automatically terminated at any desired point by the adjustable stops Z Z having bevel faces z and parallel faces yz, and operatin g through lever 1 upon the shifter.
But-independently of the above, the stroke of the carriage may be, by hand of the operator, revers ed at any point, or the carriage started on return stroke after stopping, by means of the optional stopping and starting rod 2, whose slotted arm 3 embraces wrist 4 on the shifter. 5 is a sliding rest or table, supported on ways .6, secured in front of the pedestal, and having a rack, 7, which receives a pinion, 8, having a winch, 9, accessible to the operator. (See Fig. 4.) A bead, 10, lugs 11 11', and wedges 12 12 enable the sill 13, or other stuff to be gained, to be rmly secured upon the rest. Adjustable stops 14 14', striking a detent, 15, limit the longitudinal shift of the stuff. Said detent is held to its elevated and eii'ective position by spring 16, and has a handle, 17, which, being engaged under a suitable projection, temporarily withdraws the detent and permits any desired longitudinal shift of the rest. A treadle, 18, enables the operator to momentarily depress the detent by means of his foot, when desired.
2 Mareas It will be seen that the operatoi` is enabled, by the screw L, to determine the nominal elevation of the head for the time being to suit the height of the stuft', and this without affect ing the position of the lever by means of which the cutter is lowered for cutting, and by which the depth of eut may be momentarily determined; or, in other words, the screw is for adjusting the head to different thicknesses of lumber, but the lever is only for giving depth of gain, and is always convenient to the operator, its height being' unaected by the sereT adjustment aforesaid. Owing to the rack being stationary and the impellin g mech- VY'anism of the carriage upon which the cutter is mounted being carried by and moving therewith, I am enabled to maintain said pulleys in motion without slacking their belts and without any belt=tightenen I do not claim as new a cutting-tool made to travel across the material for cutting gains, such being fully described in Patent No. Jl to Thomas Holt, June 22, 1869, and being old and well known. Y
I claim herein as new and of my inventionl. A Wood-working machine to form notches, gains, and rabbets, constructed, organized, and operating in the manner and for the purposes hereinafter specified.
2. The reciprocating` head C, in combination with the lever I and screw L.
3. The combination of the inclosed carriage or reciprocating trunk B with the belt-shifting and starting devices herein described, all constructed substantially as and for the purposes specified.
4. The counterbalanced and vertically-movable head G, operated by the lever I, in combination with the stops N N 0 IWp and adjusting-screw L.
In testimony of which invention I hereunto set my hand.
