IMPROVEMENT IN DOVETAlLlNG-MACHINES.
Specification forming part of Letters Patent No. 119,113, dated September 19, 1871.
- To all whom it may concern:
i of this specification.
.The nature of 'our invention consists in the construction and arrangement of a machine for dovetailing wood, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a side view, andFig. 2 a plan view of our entire machine. Figs. 3, 4, 5, and 6 are views of thebits used; and Fig. 7 shows a portion of the frame.
A represents the frame-work for the support of the machinery. B B are boxes to hold the axle of the mandrel or drum from which the power is obtained. O G are corner boxes for the carriagetowork perpendicularly in. The corner box es on one side are stationary, while those on the other side are attached to sliding crossbars A in the frame,and said CI'OSSrbZLI'S adjusted by means of set-screws a a, so that in case of wear of the upright slides supporting the carriageframe, they can be moved inward and kept tight. D is the frame-work supporting the carriageslides. E E are upright slides, working in the corner boxes 0 O, by which the carriage is raised and lowered perpendicularly. F is brace-work supporting the carriage-frame above the spiralspring. A rod, b, passes perpendicularly from the center of theframe-work D through the bracework F and connectin g with the treadle, said rod being, below the brace-work, surrounded by the spiral-spring d for the purpose of elevating the bed-plate on which the material to be dovetailed rests, and'keeping it in position. G G are the stops for regulating the length of the dovetail.
H is a shaft in which the stops are shifted from one position to another. I is a gauge for bringing the work square and causing same depth of out throughout. J is the bed-plate or table on which the material to be dovetailed is placed. K is a stop on the under side of the table J, which, by contact with the stops G G, regulates the size (length) of the dovetail. L L are carriageslides on which the bed-plate rests on carriage. M is the stationary flame-work on the table for holding the material in position, the material being held by the screw 6 working in the nut f which slides in said frame. N is the treadle for lowering the bed-plate or table J. O is a screw for regulating the depth of cut of the dovetail. P is the mandrel or drum for holding the bits. R It are the bits for cutting the dovetail. The bit It is straight, as shown in Fig. 3, with an opening cut through, and cuts what is termed the pins of the dovetail; while the bit R has two concave sides, as shown in Fig. 5, and cuts the holes for the pins. q
The bits are placed in the mandrel, which is kept continually revolving. The wood to be dovetailed is placed upon the bed-plate upon the carriage, and the end of the wood placed firmly against the guide I above the bit. The wood is then brought in contact with the bit by using the foot-lever or treadle N to lower until the carriage strikes the screw 0, which is previously set for the depth required. The length is regulated by using the stops G G beneath thebed-plate, extending across the framework, which can be opened or closed, and the distance between these pins or stops gives the distance between the pins of the dovetails. After setting the screw for the depth and the stops for the distance, and having wood placed upon the bed-plate, by the treadle it is brought to the depth desired. Then, by moving the carriage to and fro until it strikes the pins beneath, cut the corners round and form the pin of the dovetail, using the straight bit R. In using the other bit B change nothing, holding the carriage against the pin, and bring down with the treadle, which causes the bit to cut through the Wood; then move the carriage until it strikes the next pin, and bring down again, and so on.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. The arrangement of the frame-work 1), slides E E, brace-work F, rod 1), spring (1, and treadle N, substantially as shown and described, and for the purposes herein set forth.
2. In combination with the frame D provided with slides E E and operated by means of the treadle N, rod b, and spring d, the corner boxes C O for guiding the slides E E, when said corner boxes are arranged substantially as shown and described, so that they may be adjusted to compensate for wear, as herein set forth.
3. The table J provided with stop K, in combination with the adjustable stops G G, frame M, sliding-nut f, screw 0, adjustable gauge I, and
