Description
UNITED STATES PATENT OFFICE.
HENRY J. HALE AND HENRY J. HALE, JR., OF INDIANAPOLIS, INDIANA.
IM PROVED DOVETAI LING-MAC'HIN E.
Specification forming part of Letters Patent No.- 37,8 I 2, dated March 3, 1863.
[o all whom t may concern. n
Be it known that we, HENRY J. HALE and HENRY J. HALE, Jr., both of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Dovetailing-Machines; and we hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings and letters of reference marked thereon, which form part of this specification.
Our invention relates to the formation or working of dovetail mortises; and it consists of the several parts and devices hereinafter described to accomplish that purpose.
In order that others duly skilled may be enabled to understand and construct and use our invention, we shall proceed to describe it in detail.
In the accompanying drawings, Figure 1 is a perspective view of our doyetailing-machine complete. Fig. 2 is a vertical projection or elevation of one of the oblique chiselsand its accessories. Fig. 3 is a vertical projection of the side of horizontal chisel in its connection with oblique chisels. Fig. 4 is a horizontal projection of horizontal chisel and accessories.
Like letters of reference designate like parts in all the drawings. l
A is the bench or bed of the machine, supported on uprights or legs a a a. a. About midway of the length of bench a tall and strong upright, B, is secured. This upright is constructed, preferably, of castiron, but may be of any suitable and convenient material. The upright B is bifurcated at top, and upon each branchbb a journal-box, c, is formed, the caps bein g secured with screw-bolts, as shown.
C is awalking-beam,properlykeyed on axle d, which is journaled in boxes c c, alreadyT described. In one end or arm of walkingbeam C a slot, e, is formed, the use of which will be shown further ont To the lower part of upright B two plates, f f, are secured by means of screws g g g. These plates are formed each with a dovetail groove, h, and the plates are so afixed to the upright that the grooves are inclined to each other downward and inward. Moreover, the inclination of the grooves may be varied, for at the bottom of each plate there is only one screw, which acts as a pivot, and at the top there are two screws, which, passing through slots i t in plate, enable the same to be moved in or out on the segmental groundj. In each ofthe dovetail grooves h a slide, k,
is made to work, and to the lower end of each right- B, just described, two plumberblocks, D
D', are secured, having proper journal-boxes formed in each. The axle or shaft E is journaled in these blocks, and to the one end of said shaft, outside of bench or journal-box D, the flywheel or drum or pulley (as may be most convenient) F is keyed, and to the other end, but inside of journal-box D', the initer-wheel G is keyed, its teeth looking outward. About midway of shaft an eccentric or crank, fn, is formed, to be noticed further as we proceed. Y l
On the side of bench A on which plumberblock Dl is secured, but very near to the up# right B, acorresponding plumber-block (not shown) to D is secured, having journal-box, &c., as in block D. In this journal-box, and in tha-t on block D', the shaft H is journalcd, said shaft having a miter-wheel, I, keyed on that end which is journaled in box D', which wheel works in gear with wheel Gr on shaft E. On the opposite end of shaft H, which passes through journal-box, (not shown,) the crankwheel J isvkeyed. To this crank-wheel one end of pitman K is connected, the other end being connected with a bolt, o, passing through slot c in walking-beam C.
By means of the bolt o in slot e the length of stroke in walking-beam may be varied, as may be understood without further explanation.
Close behind the upright B, on center of bench, the adjustable bed-plate L is affixed by the screws p p, four temper-screws, q q q q, one in each corner of said plate, serving, in combination with screws p p, to adjust it to any desirable altitude.
r r 1 r a-re four guides secured to plate L, and together forming a dovetail groove, in which the slide M may reciprocate. This slide is armed at the end nearest to upright B with a broad 'dat tool or chisel, s, which is adjusted and iXed by any suitable arrangement and number otsorews, as shown. To the other end otbolt M the pitmanN is connected, which pitman, by means of a collar, fits onto crank n of shaft E. AThe handle t on pitman N serves to disengage it from crank a when desirable.
In front of upright B, on bench A, is ar ranged the adjustable bench O. This bench consists of the lower board, u, which, being furnished with side clamps outside of bench A, is denied any lateral motion, and the side clamps being furnished with horizontal metallic tongues, which slide in grooves c v in side of bench A, it is prevented from being lifted upward.' This hoard u is firmly attached to a metallic rack underneath, which slides in a slot in bench A and gears with a toothed pinion on shaft x underneath bench A.` On
.the shaft J0 the hand-lever w is slipped, by
which the pinion is rotated and the bench 0 moved forward or backward along bench -A toward the uprights B and tools Z Zand s. Above the board u the upper board, y, is laid, and letained by the metal tongues z and corresponding tongue on other side of board u.
By means of a screw, X,thisupperboard,1 is made to traverse laterallyon the lower board. A clamping apparatus, Z, and Work-edge W, is attached to this movable bench for adjust ing and ixing' the wood to be mortised or dovetailed.
The operation `of our machine is as'follows: The board or piece of lumber to be dovetail- Vmortised, being marked oit, is laid on bench O,
adjusted with its work side against work-edge W, and clamped down. The bench AO is noW set laterally, so that the rst place marked forrdovetailing shall come directly under and in front of the tools, and the bench is slid forward up to the upright B; The driving Wheel or pulley or vdrum F, being now `set in motion, communicates throughwheels G and I With the pitman K, setting the Walkingbeam G in motion. rlrhis alternately presses down and lifts up the oblique chisels Z l, which cut into the board, and the horizontal chisel s, being alternately thrust forward and drawn backward' by pitman N on crank n of shaft E, cuts out the chips from the mortise as fast as they are taken oft by the obliquely-vertical chisels ll. As soon as one' mortise is completed, the bench is moved laterally over by screw X until the part next marked comes under and before the tools7 when the same operation is gone through, and so on as often as may be required.
Having described our invention, what We claim, and desire by Letters Patent to secure, ]S.
l. The arrangement of the vertical or oblique cutters l If, the Walking-beam C, having the slot c, and the pitman K, by Which the depth ofthe cut is regulated, in the manner described.
2. Gontrolling'the direction of the cutters v l l by means ot' the adjustable grooved plates ff, constructed and a1 ranged With reference to the slides k 7c substantially as described.
