WILLIAM BAGNALL REASONER, OF GLENWOOD, IOWA.
MORTISlNG-IVIACHINE.
SPECIFICATION forming part of Letters Patent No. 715,864, dated December 16, 1902.
Application led March 26, 1900. Serial No. 10.302. (No model.)
To all whom it may concern: g
Be it known that I, WILLIAM BAGNALL REASONER, a citizen of the United States, residing at Glenwood, in the county of Mills and State of Iowa, have invented a new and useful Mortising and Tenoning Machine, of which the following is a specification.
This invention relates to a new and novel improvement in mortising and tenoning machines.
The object of my invention is to provide a simple manually-operated machine provided with interchangeable knives, as will be described more fully hereinafter and finally pointed out in the'clailn.
In the accompanying drawings I have shown in Figure l a front elevation, with portions broken away, of a mortising and tenoning machine embodying my invention. Fig. 2 shows a side elevation, with portions broken away, of my invention. Fig. 3 shows an enlarged detached detail of the operating-pawls as used in my invention, while Fig. 4 shows a perspective view of the latching-collar as used in my invention.
My invention embodies,essentially,a standard comprisingv the lower back member A2, the upper panel 3, the side supporting members K', extending upward a suitable distance to support a table 4, and the rear reinforcing-sill M, extending the full length of the standard. y, f
The table 4, which is provided with suitable openings, is secured by means of the cleats h, as shown in Figs. 1 and 2, while the lower back member A2 is secured between the sills L L, as is shown more clearly in Fig. 1.
Secured to the sills L are the bearings D, which support the rock-shaft C, provided with the bar 12', supporting the treadle 12, as shown, and the pulley 11. This pulley 11 has extending from it a chain B, which partially winds about said pulley, as shown in Fig. 1, and at one end this chain is secured to the curved bar 10', which bar has its two ends hooked into the lower perforated ends of the depending cam-bars 7, which cam-bars passA through the table 4 and above, by means of the links 35, are swiveled to the nut-provided bolts 34 34, which bolts in turn are secured to the coupling 6. This coupling comprises two counterpart members, from the upper of which extends the hook 33, which is in engagement with the hook 32 of the coil-spring 5, the remaining hook end 3l of which is secured to the bracket 2, held by means of the nut-provided bolts 30, secured to the upper end of the panel 3.
Revolubly held within the lower member 0f the coupling 6 is the plunger-shaft 8, which shaft below is provided with a tool-receiving end 8', adapted to receive the shank ofa suitable cutting-tool 10, as is shown. This plunger-shaft Sis revolubly held by means of the nut-provided brackets 9 and 9', which pass through suitable openings and are secured to the supporting-bar N, which bar above, by means of a pin e, assists in supporting the bracket 2, While below this bar extends through the sliding bed 15, as shown. Passing through this supporting-bar N are the nut-provided screws o. and 19', the iirst being provided with the pin 20' and the additional nut a2, which nut supports the leafspring'2l, as shown in Fig. 2.
The screw 19' has secured to it the pivoted operating-handle 19, from which extends the' operating-stein 26', passing through the supporting-bar N and provided with a pin ct' and adapted to engage the blade A, this blade being secured at its remaining end by means of the pin 20' to the screw a. The leaf-spring 21 normally exerts a pressure against this blade A to force it outward, as is shown in Fig. 2.
At a suitable point adjacent the upper end of the blade A are secured to the plungershaft 8 the fixed and slotted collar 18, a detail of which is shown in Fig. 4, so positioned that the blade A works within one of the insertions or slots g to lock the plunger-shaft 8, preventing its rotation while not in engagement with the blade, but permitting the slotted collar to work up and down on the blade as the plunger-shaft is operated. The slotted collar 18 below is provided with the hand1e.36, so that this plunger-shaft 8 may be readily rotated.
Near its lower end the supporting-bar N is provided with the sheave 37, as is shown in Figs.' 1 and 2. Loosely working over this sheave 37 is achain38, and this chain is secured at each end to a pawl 50, referring now to Fig. 3, which pawl by means of the pins 53 IOO are secured to the two counterpart rock-arms 16 and 16', these arms below being pivotally secured by means of the pins 54, passing through a bracket 22, as shown. At the lower ends these approximately C shaped rockarms 16 and 16 are provided with the terminal hooks 56 in engagement with the springs 24 and 24, secured to the frame members K', as more clearly shown iu'Fig. l, so that these rock- arms 16 and 16 are normally under spring tension and forced toward one another and against the cam-shoulders of the cambars 7, as is clearly shown in Fig. 3, so that as these bars 7 are reciprocated upward and downward they engage the rock-arms 16 to force the same outward to operate the pawls 50.
Secured to the sliding bed 15, which moves transversely across the stationary table 4, is a rack the teeth of which face in opposite directions, as is shown in 13 and 13' in Fig. 1, and it is with these racks 13 and 13 that the pawls 50 50 are adapted to come in engagement. It is of course understood that the sliding bed 15 is slotted, so as to accommodate the supporting-bar N. In front the table is guided by means of the ears 40 40, so that this shifting table will move in a straight line. Secured to this sliding bed 15 by means of the screwsfare the rectangular bracket 17 and 17', secured by means of the thumb-screws 40, and these brackets support the clampingscrews 39, so that the work to be mortised is securely clamped to the sliding bed 15. To further assist in properly holding the work to be mortised is provided the rear guide-strip locked by a suitable thumb-screw, as shown in Figs. 1 and 2. This rear strip may be eliminated, if desired.
When the machine is properly constructed and arranged, the operation would be as follows: The work to be mortised is secured by the screws 3.9,when the operator depresses the lever 12 to work the rock-shaft C. This would carry downward the cam-bars 7, and as the bars move downward the two rock-arms 16 would work inward. Now the pawls 50, secured to these rock-arms,are connected by the chain 38, which passes over the pulley 37, and this chain is of such a length that only one pawl can be brought to engage with one of the racks.
Referring to Fig. 1, the pawl is shown in engagement with the rack 13, so that as the cam-bars 7 descend the rock-arm 16 would be carried backward to permit its pawl to work over one of the teeth within the rack 13, and as the cam-bars 7 work upward the table 15 would be fed the width of a tooth. These cam-bars 7 are provided below with a plurality of openings z, into which are placed pins 57, whichlimitthe upward movementof these bars, so that if the table is to be fed forward the distance of one tooth the pin 57 is placed within the first hole, as is shown at Fig. 3. Should a larger feed be desired, the pin 57 would be placed into one of the lower holes, so that the lateral feed of this table may be regulated. After the desired opening has been cut by means of the tool 10 in one direction the handle 19 is depressed to draw the blade A out of alinement with the slotted collar 18, so that the shaft 8 may be revolved to turn the tool in an opposite direction, when the shaft Sis again locked, the pawls then being changed to give a feed in the opposite direction.
The device is exceedingly simple of construction and readily operated; and,
Having thus described my said invention, what I claim as new, and desire to protect by United States Letters Patent, is
In a mortising and tenoning machine, the combination of the following instrumentali ties to wit; a standard comprising a back member, an upper panel, side-supporting members secured to said back member, a table secured to said members, said table being provided with suitable openings, a rock-shaft secured below to said back member, means to aotuate said rock-shaft, a pulley secured to said shaft, a chain extending from said pulley, a bar at the end of said chain, cam-bars projecting through said table-openings and secured to said bar, a coupling, said cam-bars being secured to said coupling, a coil-spring secured to said coupling, a bracket secured to said panel and supporting said coil-spring, a plungershaft,said plunger-shaft being revolubly held within said coupling, said plunger-shaft below being provided with a toolreceiving end, a supporting-bar secured to aforesaid table and to aforesaid bracket, supporting-arms extendingfrom said supportingbar and holding aforesaid plunger-shaft, an operating-handle in engagement with afore` said plunger-shaft to hold the same in alinement, a sheave secured to said supportingbar, a chain working over said sheave, a pawl secured to each end of said chain, rock-arms pivoted to said table, said arms at their upper ends receiving said pawls, springs to normally force aforesaid rock-arms inward against aforesaid cam-bars the lower cam ends of said bars working against and actuating said rock-arms, a sliding bed secured to aforesaid table, and rack-teeth secured to said bed and engaged by aforesaid pawls, all arranged as shown.
