SPECIFICATION forming part of Letters Patent No. 615,116, dated November 29, 1898. Application filed August 31, 1898. fierial No. 689,950. (No model.)
To all whom it may concern.-
Be it known that I, ABRAHAM VAN VVAG- NER, of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Mortising or Gang-Drilling Machine, of which the following is a full, clear, and exact description.
My invention relates to an improvement indevices to be used for boring in making mortises.
It consists of mechanism adapted to be used by hand for this purpose, and comprises the novel constructions hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a top plan view of my device. Fig. 2 is a front elevation thereof. Fig. 3 is a side elevation, with the work being operated upon shown in section. Fig. 4 is a section taken upon the line 4 a of Fig. 3, and Fig. 5 is a section taken through the bar which carries the drills.
It has been my object in producing this machine to make a device which may be used for boring various articles which are to be mortised-for instance, frames of various kinds, doors, and such like articles. Making mortises by hand, using the ordinary bit and brace, is very slow work. While such work may be done rapidly with a regular mortis ing-machine, the larger portion of the shops do not have such machines and have to do such work by hand when it is to be done.
My device is of such a nature that it will cost but little to produce, and is therefore within the reach of the ordinary small shops.
My device comprises a frame which, as here in shown, consists of the legs A, secured to a horizontal board or table A. This frame may be secured to a bench or other suitable support in any convenient manner. The edges of the top member A are provided with guides a, which receive the bars B, the latter carrying the operating mechanism. As herein shown, the guides a are formed as dovetailed grooves in the edge of the horizontal member A, and the bars B are provided with dovetailed ribs 1), fitting therein. The two bars may be connected by a cross-bar b Upon the upper surface of the horizontal member A is secured an adjustable knee 0, adapted to receive the side thrust of the work and support the same. This knee is secured to the table by means of bolts 0, which pass through the knee 0 and enter slots 0 in the table. The forward ends of the bars B are connected with an upwardly-extending frame B, having bars B located one at each end and secured thereto, thus forming slots B adapted to receive the ends of the bar D, which carries the drills. The bar D has a limited amount of vertical adjustment and may be adjusted to any position desired and then secured there by any convenient means.
passing through the frame B and entering the upper portion of the bar D, carrying the drills. Either of these devices or their equivalent may be employed.
The bar carrying the drills consists of two parts=-the lower part D and the upper part or cap D. Between the two is located a series of drill-holders, consisting of short shafts E, having upon one end a socket-piece E, adapt ed to secure the end of a drill c, and to the other end of the shaft'E is secured a pinion G, the pinions upon the drill-holders not being in mesh with each other. .Journaled in the bar in a row alongside the drill-sockets is a series of pins carrying the idler-pinions G, which are not in mesh with each other, but are in mesh with the two pinions G, which adjoin them. By means of this construction when one of the pinions is turned all the others turn and the drill-sockets are made to turn all in the same direction, so that ordinary right-handed bits may be used forboring. Rotation is given to these pinions by means of a gear-wheel G in mesh with one of them and upon the same shaft as the hand-wheel II, which is provided with a handle 71 by which it may be turned.
Upon a bracket L, which is supported from the frame, is pivoted a lever K, having a slot K in its upper end, which embraces a pin 1), projecting from the bars l3. Upon the frame is also pivoted a bell-crank lever M, forming a treadle to be operated by the foot and connected at one end by a link N with the lever K, so that when the treadle is depressed the slide carrying the operating mechanism will be forced rearward or toward the work.
In order to gage the top of the holes being bored and to make them all uniform, a series of washers P of varying thickness is provided which will fit over the bit 0. A sufficient number of these washers are provided for two or more of the bits, so that the outer one will engage the surface of the work when the hole has acquired the proper depth.
This machine is of such nature that it may be used in any shop and when not in use may be placed at one side out of the way. Its cost Its use will result in greatly cheapening the cost of work of the class for which it is designed.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent A gang-drilling device, comprising a horizontal or table member suitably supported and having grooved guideways formed in two opposite side edges and bolt-securing slots in its upper surface parallel with said edges, a work su1i porting knee adjustably secured upon the table by bolts entering said slots, a frame having two arms provided with ribs entering the guideways in the edges of the table, a lever connected to the frame to reciprocate it on its guides, the frame having guideways at each end extending perpendicular to the plane of the table-surface, a bar mounted in said guideways to have vertical adjustment, a raising and lowering lever connected with said bar, a clamping device for securing the bar in place, a series of drillsoekets mounted in said bar each provided with a pinion, idler-pinions between the drillsocket pinions and a crank connected with said pinions to turn them, substantially as described.
