ANDREW P. MERCHANT, or enrnronn, NEW YORK.
*WWPRQ'VEMENT m iDOWELING-MAC'HINES.
Specification forming part of Letters Patent No. 1 77,652, dated May 23, 1876; application filed March 6, 1875.
To all whom it may concern:
- Be it known that I, ANDREW P. MERCHANT,
of Guilford, in the county of 'Ohenango and State of New York, have invented certain new and useful Improvements in- Doweling- Machines; and I do hereby declare that the following is a full, clear, and exact description, of the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a front view of my improved .machine, one of the rests being shown in crosssection through the line a as, Fig. 2. Fig. 2 is a top or plan view of the same. Fig. 3 is a side View of one of the rests and its way.
Similar letters of reference indicate correspouding parts.
The present invention is designed as an improvement upon my former patent, granted May 28, 1861, No. 32,449, 'and reissued January 7, .1873, No. 5,222 and its object is to so construct and arrange the supports upon which the material to be bored is placed that they may be raised or lowered to accommodate them to the varying thickness of the material, in order that the holes may be bored in the center of the heading, whether said heading be thick or thin, while such change and construction of the parts so simplifies the operation that the employment of a crank and screw-rod to force inclined plates formed upon a longitudinal bar against the lower ends of the supports or 'rests is entirely dispensed with, thereby making a very simple, cheap,
and perfect operating device, for the purpose.
intended. "My invention, therefore, consists of stationary inclined ways formed upon its upper face, with grooves, into which fit and slideinclined suports or rests, the same having slotted plates working over and held in position by setscrews'w-ithinlugs upon the outer sides of the ways.
- In the accompanying drawings, A represents the base or bed of the machine, having secured near its rear edge a frame or plate, B, made in the form of an inverted T, the
horizontal arms of which are slotted longitudinally to receive the bolts 0, by which the sockets or bearings D for the bits E are secured to said frame. The upright arm of the frame B is slotted vertically to receive vthe gudgeon F, upon which the internally-toothed drive-wheel Works. The shanks or holders of the bits E are connected with the gudgeon F by two pivoted connecting-bars, G, so that the teeth of the gear wheels attached to said shank or holders may always mesh into the teeth of the drive-wheel, whether the bits be moved closer together to operate upon smaller heading, or moved farther apart to operate upon larger heading. The three gear-wheels are not shown in the drawing, and the several parts already described do not dift'er'material- 1y from those shown and described in my former patent.- r
The several parts of the machine which con stitute my invention will be understood from the following description:' Near each end or side of the base or bed A is rigidly secured, by bolts, screws, or other suitable means, an inclined way, 1, the same having formed upon its upperface grooves a. (Shown in dotted lines,
Fig. 3.) These ways have upon their outer sides lugs e', into which the lowerends of screws J work. The supports or rests, as represented at H, upon which the headingis laid to be bored, are formed with slotted side plates h, the screws J passing down through the slot. The plates h are slightly above the inclined edge of the rests H, to allow said edge to fit within the groove a of the inclined ways I. By this construction, by moving the rests H toward the bits E, the upper edge of said rest will be raised, and by moving the said rests in a direction away from the said bits their upper-edges will be lowered, so that therests can be readily adjusted to support I the heading in such a position that the dowel ing'the holes must be made a little out of v truethat is, one hole slightly farther from the face than another-which cannot be done where the rests are only capable of simultaneous adjustment.
Having now fully described my invention,
What I claim as new,and desire to secure by Letters Patent, is-- y In a doweling-lnachine, the stationary inclined Ways I, having upon their face grooves a, and the lugs i, with set-screws J, in combination with the independently-adjustable inclined rests H, formed with slotted plates h, substantially as and for the purpose set forth.
