lviPRVEMENT iN WiRTlSING-MACHINES.

Specification forming part of Letters Patent No. 15H26@ dated May 26, 1874; application filed February 12, 1874.

To all whom lit may concern:

Be it known that I, AUGUST BORNEMAN, of Lancaster, in the county of Fairfield, State of Ohio, have invented certain new and useful Improvements in l\Iortising-l\Iachines, of which the following is a full, clear, and exact descrip- `equivalent device; and consists in providing the block in which the clamping-screw is mounted with lugs or ears, one of Which is hinged; and also in providing the frame upon which this carriage is mounted with movable stops, againstivhich the lugs or ears abut, for regulating the length of the mortise, and obviating the necessity for marking or lining said mortise, as hereinafter explained.

In the accompanying drawings, A represents the frame upon which thc parts are mounted, and B the lower table, upon which thecarringe C is mounted. The outer edge of the table is provided with a flange, B', ruiming its entire length, and beveled or made flaring upon its inner side. Upon this iiange B are mounted movable stops D, which are free to slide upon it, except when held in place by set-screws d. The table C has cast or otherwise secured to it a block, C', in which is mounted the clamping-screw Which holds the frame-piece to be mortised in position While being acted upon by the auger or chisel. This block has cast or otherwise secured to it at one side a lug or ear, E, and, upon the other side, is provided with a pivoted latch, F. This latch and lug, which regulate .the extent of the throw of the carriage C, are controlled in their movements by means of the adjustable stops D, one upon each side of the block C. The flange B is gaged or lined upon its outer face for setting the stops D the required distance apart/or for gagin g the distance of play for the carriage C, and thus regulating the length of dut ofthe mortise.

The stops eing set at the desired points, as before set rth, the latch is raised up and passed over the stop upon the side with it, which allows the carriage to be drawn back under the auger to bore the hole, and when moved back under the chisel the latch will drop down behind the stop, and the mortise cut while moving the carriage from one stop to the other. It will thus be seen that when the stops are gaged for one piece, any number can be mortised with the same length of cut, Without the necessity ot' measuring and marking each piece separately.

The distances apart at which the mortiscs are to be cut in the same piece is regulated by the spring-catch II and gage-piece I, arranged upon the inner side ot' the carriage, this latter arrangement, in connect-ion With the stops for gaging the carriage, enabling the operator to mortise any number of pieces alike, without measuring or marking them before being put in the machine, thereby eli'ecting a great saving of time and labor in preparing duplicate pieces for the action ot' the machine.

Parts of the machine not particularly described may be constructed in any usual manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The lug E and latch F, applied to the carriage O, in combination with the adjustable stops D, arranged and operating substantially as described.

AUGUST BORNEMAN.
