Letters Patent No. 103,750, dated May 31, 1870.
IMPROVEMENT IN C'TTERS FOR DOVETAILING- MACINES The Schedule referred to in these .Letters Patent and making part of the same.
To all whom it may concern:
Be itkuown lthat I, DEDRICK JORDAN, of Charlestown, in the county of Middlesex andState of Massachusetts, have invented a new improvement in Gutters for Dovetailing-Machine; and I do hereby declare the following, When taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part ot' this specification, and represent in- A Figure l, a side view;
Figure 2, an end view of the cutter-head; Figure 3, a vertical central section; and in Figure 4, the cutter detached. This invention relates to an improvement iu the construction and arrangement of the cutters for dove- ;'tailing machines, the object being to arrange the cutter so as to get au extended cutter whereby it may be more perfectly secured; and
The invention consists in arranging the cutter upon a seat inclined to the axis'of the cutter-head, and a clamping device passing through the cutter-head, so as to draw down upon the edge of the cutter, the inclined seat giving a long bearing to the lower edge of the cutter. Ais the cutter-head, which is bored out so as to lpass on over a spindle, C, the said spindle provided with a head, B.
- D is the cut-ter or cutters, one of which is shown in g. 4. Y
The seat is formed in the head A, as denoted by the broken line, g. 1, inclined to the axis of the said head, and the bearing ot' the head B is made parallel thereto. In consequence of this inclined seat fthe shape ot' the cutter is such that a long bearing is attained upon the lower edge.
The advantage of this cutter over the common straight cutter, in'addition to-an increased bearing, is, that-where the seat is at right angles with the axis the cutter must be of the shape denoted in Figure 5, giving but a very slight bearing upon the lower edge, and that wears away so rapidly by the grinding-oi thc cutter that new cutters 1n ust he constantly supplied, whereas in my invention the lower bearing is the longest iu the beginning, and may be worn until the bearing is reduced to as slight an extent as a straight cutter. Hence, while. the cutters cost no more, they will last very much longer.
The cutters are set int-o their seat in the head A below their head B, and bound in place by forcing the head A up by means of the spindle through and ont below the head.
l claim as my iuvention- The herein described cutter-head for dovetailing machines, having the cutter arranged so as to be tixed upon an inclined bearing in the head, in the manner described.
DEDRIOK JORDAN.
