DRILLING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 517,298, dated March 27, 1894.
Application filed October 12,1893. Serial No. 487,929- (No model.)
T0 00% whom it may concern.-
Be it known that 1, Louis REroHERr, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and Improved Drilling-Machine, of whichthe following is a full, clear, and exact description.
The object of the invention is to provide a new and improved drilling machine, which is simple and durable in construction, very effective in operation, and more especially designed for drilling small holes in glass and other substances and articles.
The invention consists of certain parts and details'and combinations of the same, as will be hereinafter described and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure lis a side elevation of the improvement with parts in section; and Fig. 2 is an end elevation of the same, with the spring and set screw support thrown down.
The improved drilling machine is provided with a suitably constructed frame A, in which is journaled a driving shaft B, provided on its outer ends with gear wheels 0 and G, of which the gear wheel 0 is provided with a crank arm 0 for conveniently turning the said shaft B by hand, or the said shaft may be provided with a pulley, as indicated in dotted lines in Fig. 1, to be driven by power. The gear wheels 0 and O mesh in pinions D and D, respectively secured on the outer ends of spindles E and E, respectively, mounted to turn in suitable bearings in the main frame A, the said spindles being in alignment one with the other, and in their adjacent ends are secured the diamond pointed drills or bits F and F, respectively, fastened in place by set screws G and G, respectively. The extreme outer end of the spindle E is pointed and engagedbya set screw H, screwing in a bracket I, mounted to swing on a pivot I, secured to one end of the frame A, as plainly illustrated in the drawings.
In the bracket I is arranged a segmental notch 1 adapted to be engaged by a set screw 1 screwing in the end of the frame A to hold the bracket in place at the time the set screw H engages the pointed outer end of the spindle E. By this arrangement a longitudinal outward sliding of the spindle E is prevented,
so as to hold its drill or bit F in contact with h wise formed with a point and is pressed on by the free end of a spring J, held on a pivot J, secured to the end of the frame A opposite that on which the bracket. I is located. The spring J may be re-inforced by a series of additional leaves J likewise held on the pivot J and serving to press the spindle E inward, to feed the drill F into the article to be drilled. The machine is designed chiefly for boring eye-glasses; and it is requisite that the pressure on the spindles be slight at the beginning of the operation, in order to avoid chipping the glass. The provision of a series of spring leaves so arranged that one may be reinforced by another and thus graduate the pressure on the spindle, is therefore important. I
The operation is as follows: By the operator moving the spring J, out of engagement with the spindle E, the latter can be moved outward so as to permit of inserting the article to be drilled between the two drills F and F. When this has been done, the spring J is engaged with the outer end of the spindle E, so that the latter is pressed inward to engage the drill F with one side of the article, the other side being engaged by the other drill F. When the main shaft B, is rotated, the gear wheels 0 and O impart rotary motion to the pinions D and D, so that the spindles E and E turn in their bearings. Now, as the two drills F and F rotate and are in alignment with each other, they drill a hole in the article from opposite sides, it being understood that the drill F by being pressed on by the spring J fits into one side of the article and presses the latter with sufficient force to cause the article to advance on the other drill. The spindle E can be fed inward by adjusting the set screw H, but the inward movement of both spindles is limited by the pinions D and D finally abutting against the ends of the frame A. When this position is reached, the points of the drill are close together and the hole has been drilled. The pinions D and D have their faces made considerably wider than the gear wheels 0 and C, so that the pinions remain in mesh at the time the spindles E and E are fed inward in the manner above described. When a hole has been drilled, the operator throws the springJ downward and slides the spindle E outward to permit of conveniently removing the article.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. A drilling machine, comprising two aligned, rotatable and slidable spindles carrying drills, means for rotating the drills while moving axially, and a series of independent spring leaves acting on the outer end of one of said spindles, and said leaves being adapted to be reinforced one by another, for the purpose of gradually increasing the pressure on the drill, as shown and described.
2. A drilling machine, comprising two aligned rotatable and slidable spindles, drills held in the adjacent ends of the said spindles, and a series of spring leaves held by a common pivot and separately adjustable thereon, and pressing on the outer end of one of the spindles to feed its drill into the artiole, substantially as shown and described.
3. In a drilling-machine of the class specifled, the combination with the frame, driving shaft, and its gears, the drill-carrying spindles aligned and adapted to slide and rotate as specified, and provided with pinions having a meshing as well as sliding engagement with said gears, a swinging bracket pivoted at one end of the frame, and means for locking it to said frame and pressing the spindles toward each other, whereby the spindles may be rotated while sliding and detached when 40 their work is done, as shown and described.
