MORTlSlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 706,458, dated August `5, 1902. Applicatlonled November 14, 1901. Serial No. 82,311. (No model.)

To all whom it may concern:

Be it known that I, CHARLES J. SEAQUEsr, a citizen of the United States, and a resident of Silverlake, in the county of Cowlitz and State of Washington, h ave invented a new and Improved Mortising-Machine, of which the following is a full, clear, and exact description.

The invention relatesto woodworking `Inachineryyand'iits object' is to provide a new and improved; 'mortising-machine which )is simple and durable in constructionV and arranged tobeactuated byhand 'in a very easy manner to accurately'form "mo'rtises in wood-- work t 1 The invention consists of novel features and f parts and combinations of the` same,'as will be fully described hereinafter and-thenpointed out inthe claims.

A practical embodiment of the invention is represented intheaccompanying drawings, forming a part ofthis specification, in which similar characters of reference `indicate corresponding parts in all the views.

Figure l is [a side elevation of the improvement. Fig. 2 isa longitudinalsectional side elevation of the same on the line 2 2 of Fig. 3. Fig. 3 is a plan viewof the same. Fig. 4 is a transverse section of the same on the line 4 4 of Fig. 3. Fig. 5 is anenlarge'd endelevation of one of the` gouging-tools. Fig. 6'is a side elevation of the same..Y Fig. 7 is an enlarged end elevation of the tool-post, and Fig. 8 is a side elevation of the same.

On the top of a suitably-constructed bedplate A are arranged longitudinally-extending guideways A, in which is mounted to reciprocate a carrier B, rformed on .itstop with a rack C, in mesh with a gear-wheel D', mounted to rotate on a shaftE, supported by brackets held on the main bed-plate A. The gearwheel D is provided with a suitable handle D', adapted to be taken hold of by the operator to impart aturning motion to the gearwheel D, soas to` causethe rack C and the carrier B to move longitudinally in the guideways A-that is, either forward or backward, according` tothe direction in which the handle D is moved. When the handle D is swung forward, the carrier B moves rearwardly, and when the motion of the handle D is reversed a forward movement is given to the carrier.

On the top of the latter and near the front end thereof' is formeda bearing B for the shank F of a tool-post F,formed with a socket adapted to receive the shank G of a tool G, which mayfbe anlordinary mortising-tool, as indicated' in Figs. 1, 2,?and3, or a gougingtool G3, asillustrated in Figs. 5 and t'. The shank F of the tool-post F is preferably eccentric relative'to the socket for the shank G or G2 of the toolsG` and G3, andthe said shank F is adapted `to befastened in place in the bearing by a suitable set-screw B2.

The wood tojbemortised is held on the top of a Vtable H, set in a depression A2, formed ing post H,held vertically adjustable in a suitable bearingv carried by the bed-plate A, so as to bring the woodin proper position relative to the tool G orGS. A set-screw-H2 serves to fasten the postH, and consequently the table H, in positionafter the desired Vertical adj ustment of the table has been made. The outer side of thewoodrests against an abutment A3, arranged `in the shape of an upturned flange integral with the bed-plate A, so that when the tool moves in engagement with the wood the latter is held against outward movement by the abutment A3. In order to prevent the wood from following the cuttingtool'. when the latter is withdrawn for a new stroke,wl provide a clamp I, adapted to abut against the inner side of the work and formed with an elongated slot I', engaged by a setscrew I2, screwing `in the top of the bedpla'te A, the arrangement permitting of sliding the clamp I longitudinally, so as to firmly engage wood of different thicknesses. When the wood is in position on the table I-I and the operator swings the handle D rearwardly, the carrier B moves forward and the tool G 0r G3 engages the wood yand cuts a mortise therein, and when the handle D' is swung forward the carrier B moves rearwardly, and with it the tool G or G3, to move the tool out of engagement with the wood. The abovedescribed operation is repeated asoften as deemed necessary'toform thedesired mortise.

Having thus described my invention, I claim as new and desire to secure by Letters Patent* on the forwardlendof the bed-plate A, and i the said tablelH- is provided with a dependl. A mortising-machine, comprising a bedplate formed with longitudinal guideways, a carrier mounted to reciprocate in the said guideways, 'a rack on top of the said-carrier, a handled gear-wheel in mesh with the said rack, a bearing on the top of the carrier near The front end thereof, a tool-post for supporting the tool and having a shank held in the said bearing, a table held vertically adjustable in a depression in the said bed-plate near its forward end, an abutment at the forward end of the bed-plate and a longitudinally-ad'- justable clamp on the top of said bed-plate.

-2. A mortising-machine, comprising a bedplate formed with longitudinal guideways, a carrier mounted to reciprocate in the said guideways, means for reciprocating the said carrier, a bearing on the top of the carrier near the front ends thereof, and a tool-post formedwith a socket-for the shank of the tool and having a shank held in said bearing, the shank of the tool-post being eccentric to said socket.

,3. A hand-power mortisng-machine, comprising a bed-plate havinga depression neary its forward end'and an abutment at the end of the depression comprising an upwardlyextending ange integral with the bed-plate,

a bearing carried by the bed-plate at the depressed portion, a table provided with a central depending post held vertically adjustable in said bearing, a set-screw extending through the side of the bearing and engaging the post to fasten the table in the adjusted position, a carrier mounted to .reciprocate on the said bed-plate toward and from said table, means for reciprocating said carrier, and a tool-support on the said carrier and carrying the tool as set forth.

4. A mortising-machine, comprising a bedplate, formed with longitudinal guideways, a carrier mounted to reciprocate in the said guideways, a rack on top of the said carrier, a handled gear-wheel in mesh with the said rack, a bearing on the carrier, a tool -post adapted .to receive a tool, and having a shank held in said bearing, a table held vertically adjustable in a depression in the bed-plate, and a slotted clamp held longitudinally adj ustable on the top of said bed-plate, the forward end of the clamp being adapted to engage wood of dierent thicknesses.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES J. SEAQUEST.
