BORING-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 739,381, dated September 22, 1903. Application filed November 1902. Serial No. 131,489- (No model.)

To all whom it may concern; 1

Be it known that Ll lnunv B. Blussnt'a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, haveinvented and produced a new and original-1m provement inBoring-Ma chines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates'to that class of machinetools employed in metal-boring for heavy machinery, the objects of the present improvements being to provide more conven- I parts.

The invention consists in the improved boring-machine and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings,

in which like characters of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of a part of a boring-machine embodying my improvements, the means for turning the boring-bar being omitted. Fig. 2 is aplan of the same,

the boring-bar being omitted. Fig. 3 is an end view, and Fig. 4 isa vertical section of the same taken at line 00, Fig. 1. Fig. 5 is a detail section taken at line y, Fig. 4 and Fig. 6 is a detail perspective view, parts being broken away to show the construction more clearly.

In said drawings, a indicates a suitable bed: plate, and b the table upon which the work to be bored is arranged.

c c are ordinary screws by means of which the table I) is raised or lowered.

(1 indicates the yoke or bearing-carrier for the free end of the boring-bar, and e indicates the said boring-bar adapted to be ro-. tated by any of the devices'(not shown) com: The said carrier dmon to boring-machines. rests upon the'bed-plate a and may be adjusted horizontally thereon, the said bedplate being preferably provided with grooves f, adapted to receive the heads of T-bolts g, which bolts extend up and out from said grooves through foot portions 71. of the car rier; At the top of each foot portion the said T-bolts are provided with nuts 43, by means of which the carrier is rigidly.fastened in place after adjustment. The said carrier d is vertically slotted in both the opposite sides,

of each of the slides la is provided with a lug or boss mresting upon the said table, whereby when the table I) is raised by the screws c 0, above referred to, the slides in It will also be raised with the table, moving freely in said slots At the lower inner portion of the slides k are threaded bosses or projections 11., which act as nuts to receive longitudinally-disposed adj ustin g-scre'ws 0 0. (Shown more clearly in Figs. 1, 4:, and 6.) The said screws 0 are borne in suitable brackets, boxes, or bearings 10 19, formed on or secured tothe lower side of the table at or near the opposite longitudinal edges thereof. Said screws 0 are designed to be turned simultaneously by means'of suitable gearing, the gearing preferred being shown in Figs. 1, 2, and 3, where the said screws 0 0 are shown to be provided with mi:

ter gear-Wheels r 1", which mesh with miter gear-Wheels s s,arranged up'on'the shaft 6, interposed between the said screws 0 0 and carried by a bracket of hanger u, attached'to the table. One of the screws is preferably'provided with a suitable head v to receive a handcrank, (not shown,) so that when the crank is turned the power of the hand will be transmitted to the screw having the crank and through the bevel-gearing and intermediate shaft t to the other screw, imparting a uniform and simultaneous action to both screws.

The top of said carrier or yoke d is provided with a bearing 3 for the boring-bar e, as shown more particularly in Figs. 3 and 4.

The carrier or yoke d is usually provided with a bolt 4, which extends through the slots j 7' and preferably across the top of the table, so that when the nut 5 on the said bolt is screwed up the upright sides of the yoke or carrier will spring together to clamp the table between them and to give stiffness and firmness to said table.

In operating myimprovements, the table I) having been raised orlowered to its proper position, I apply a hand-crank to the head 1; of one of the screws 0 and turn the same, the movements being transmitted to the other screw 0, so that the two screws move together within their hearings or boxes attached to the table. The turning of the screws within the threaded nuts of the slides causes the'carrier to slide longitudinally or horizontally upon the bed a to the desired location suited to support the boring-bar, after which the nut 5 on the bolt 4 is screwed up to cause the standards 6 6 of the yoke or carrier to spring together and clamp the table, after which the boring maybe effected in any ordinary manner.

Having thus described the invention, what I claim as new is 1. Theimproved boring-machinehereindescribed, comprisinga bed a, a vertically-movable table I), a yoke or bearing-carrier d,adapted to receive and support the boring-bar, a screw 0, arranged lengthwise of the table in suitable bearings attached to or formed on said table, a slide arranged on the carrier, and movable with and along the table and having a nut or threaded bearing to receive the screw, whereby when the said screw is turned the said carrier will be moved horizontally along the table, substantially as set forth.

2. In a boring-machine, the combination with a suitable bed, table and boring-bar, the said table being vertically adjustable in its relation to the bed, of a carrier provided with bearings at the top for said boring-bar, and being adapted to travel longitudinally upon said bed and table, screws arranged lengthwise of the table in suitable bearings thereof, the said carrier being provided with slideways for the slides, slides arranged in said slideways, and the screws being arranged in the bearings of the slides, and gearing connecting the said screws, whereby the said screws will turn simultaneously and effect a longitudinal movement of the carrier with respect to said bed and table, substantially as set forth.

3. In a boring-machine, the boring-bar carrier, comprising slotted standards and a hearing for the bar, in combination with slides arranged in the slots of the standards, screws having hearings in the slides, a table disposed between the slides and being provided with bearings for the screws, said table forming a guide for the carrier and being vertically adjustable, and means for turning said screws, whereby a movement of the carrier longitudinally of the table is secured.

t. In a boring-machine, the boring-bar carrier comprising slotted standards and a bearing for the bar, in combination with slides arranged in the slots of said standards, screws attached to the slides, an intermediate shaft between said screws, a vertically-adjustable table disposed between the slides and provided with bearings for the screws and a bracket for the intermediate shaft, gearwheels connecting said intermediate shaft with said screws, and means for turning said intermediate shaft, whereby the carrier is moved longitudinally along guides and at the same time independent vertical adjustment of the table is permitted.

In testimony that I claim the foregoing I have hereunto set my hand this 15th day of October, 1902.

HENRY B. BINSSE.
