Application filed May 10, 1913. Serial No. 766,851.
To all whom it may concern:
Be it known that I, ALEXANDER B. CAMP- BELL, J r., a citizen of the United States, and a resident of Jacksonville, in the county of Duval and State of Florida, of the United States of America, have made a new and useful Improvement in Pocket-Cutters, of which the following is a specification.
My invention is an improvement in pocket cutters, and has for its object to provide mechanism for quickly and easily cutting pockets in the jambs of window frames, for receiving balanced sashes, wherein the cutting is done by a continuous moving chain.
In the drawings Figure 1 is a front view of the improved cutter, Fig. 2 is an enlarged section on line 2-2 of Fig. 1, Fig. 3 is an enlarged front view of one end of the cut-- ter with parts of the chain in section, Fig. 4 is a partial top plan view of the cutting chain, Fig. 5 is a perspective view of a portion of the jamb showing the pocket cut, Fig. 6 is a front view of a portion of the jambshowing the manner in which the pocket is cut, and, Figs. 7 and 8 are sections on the lines 7-7 and 8-8, respectively of Fig. 6.
The present embodiment of the invention comprises a supporting frame, consisting of lateral guides 1 and 1 and an intermediate guide 1". The said guides are held together by a connecting plate 2, in such manner that a recess is formed on one face of the supporting frame at each end thereof and grooves or channels 3, the said grooves or channels connecting the recesses, and the outer side of each groove or channel is continuous with the adjacent outer side wall of the recesses. A shaft 1 is journaled in each of the recesses, at the center thereof, and midway between the opposite side edges of the support, and a sprocket wheel'5 is keyed to each shaft by means of a key 6. The inner end of each of the recesses 2 is arcshaped as indicated at 7, the circle upon which the arc is formed having the shaft 4. as its center. An endless chain is supported on the sprocket wheels, said chain being composed of links 8 and 9, connected by pins 10. The links 8 and 9 are arranged in series, and in pairs, and an arbor 11 is arranged on each pin 10 between the links. From an inspection of Fig. a, it will be noticed that the links are arranged in inner and outer series, the innermost links at the side of the. chain being in alinement and arranged with their adjacent ends spaced apart from each other, and the outermost links lap upon the meeting ends of the innermost links. The outermost series of links at one side of the chain is composed entirely of the links 9, before mentioned, and washers 12 are arranged between the heads of the pins 10 and the outer face of the said links. Each of the said links 9 is provided intermediate its end with a laterally extending cutting blade 13, each of the said blades having a cylindrical shank 1% which is connected to the link 9 in any suitable manner. The free end of the blade 13 is beveled as indicated at 15, from front to rear, with respect to the direction of motion of the chain, this direction being indicated by the arrow in Fig. l. All of the blades 13 are similarly arranged, and each blade provldes a cutting point at the front end thereof because of the manner in which the blades are beveled. The blades 13 are of the same length, so that the point of each blade is in the same plane with the points of all the other blades. The teeth of the sprocket wheels 5 are of a length and size to extend between adjacent arbors 11, and the washers 12 are split washers as shown in Fig. 3.
The guides 1, 1, 1 are so arranged, that the channels 3 are just of sufiicient width to permit the free passage of the arbors, and the opposite faces of the said guides from the blades 13-are recessed on each side of the grooves 3, as indicated at 16, to permit the free passage of the links 8. The said recesses16 are adjacent the connecting plate 2, so that the said links move between the said connecting plate and the bottoms of the recesses. The links at one side of the chain move in the recesses 16, while the links 8 and 9 at the opposite side of the chain are on the opposite face of the supporting frame formed by the guides. A pulley 17 or the like is secured to one of the shafts L, for engagement by a belt, to connect the said pulley with a suitable source of power, in order to rotate the same. The plate 2 is arranged on the opposite face of the support from the blades, to connect the three portions of the frame; namely, the upper and lower guides 1 and 1 and the intermediate guide 1".
In operation the supporting frame formed of the guides 1, 1 and 1 is arranged adjacent to the jamb 18, as shown in Fig. l, with 1 the blades 13 in position to engage the adja- I cent face of the jamb; The pulley 17 is then rotated in any-suitable manner, to cause the chain to move longitudinally on the sprocket Wheels. The blades engage the adjacent face of the jamb, and cut a continuous channel 19 in the said 'jamb, the said channel corre sponding in outline to the-:outline of-the:
chain. As the bladescut, the supporting frame i's'mcved toward 'thejam'b until the blades have cut approximately half through the jam'b. The jamb is then reversed, and a similar cut is made ontheoppositeside of by the cut is staggered or off-set lon gitudi nallywith respect to 'th'e'portion' of the j amb inclosed-byfthe first named cut. That is, the" jamb and the supporting frame are moved longitudinally slightly with respect to each other, so that the first cut 19 and the second cut 20' are not in registry with eachother. The cut 20 is the same'depth as the cut'19 so that the-aggregate depth ofthe cuts is equal to the thickness of the janib, After the sec-- 0nd out has been made, ablowfrom aham-' meri or the like will dislodge that portion 21 of-the' jamb inclosed by the cilts 19 and-20 and the said portion may beremoved; After I the weights have been p1aced,.the Saidpor tion 21 may be replaced, and a 'screw 22 mavfl be inserted to engage the jamb and the pori tion- 21, whereby to holdthe saidportion in place, as shown in Fig. 7 Lips or ledges are thus formed to prevent "dislocation of the: 40
