PORTABLE GROOVE GUTTER,
Applicationled January 2'?, 1926. i Serial No. 84,043.
This invention relates to an improved machine for use in grooving the underside oi' the bottom rail of a window sash.
The general object of the invention is to provide a portable device having means, such as a circular saw, 1:01' cutting a groove, and which is adapted to permit a window sash to be moved over the same with the underside of its bottom in engagement with the grooving member, so that a groove will be cut in the bottom of the sash.
rlhe device is particularly intended 'for use in connection with applying weatherstrips to a Window frame, an-d enables the operator to rapidly groove the underside of the bottom rail of the window sash, so th at it will receive the weatherstrip which is placed in'position on the bottom of the window traine.
The invention embodies a case or box, ordinarily oblong in shape, and having mounted therein a motor provided with circular saw on one end of its shaft, means for connecting the motor to an ordinary electric light socket, and a lid provi-ded with a slot through which the upper part of the saw projects, and with an adjustable guiding part which enables the position of the window sash, when placed on the lid, to be correctly adjusted relative to the saw, so that the groove may be formed at the desired point in the bottom of the sash.
The invention is illustrated in the accompanying drawing, in which- Figure 1 is a plan view of my improved portable groove-cutter; Y
Figure 2 is a view in front elevation of the same; j,
Figure 3 is a plan view with the lid on the device raised;
Figure 4 is an end view of the device;
Figure 5 is an enlarged sectional view on the line 5-5 of Figure 1; and
Figure 6 is a sectional view on the line G-G of Figure 1.
Referring now to the drawing', the numeral 1 indicates the casing of my device, which is rectangular in shape and, roughly, has the appearance of an ordinary tool chest, although somewhat larger. The casing is pros vided with a lid 2 hinged thereon at the rear, as indicated at 3, which lid is provided on its upper side along the front edge `with a metal strip 4, forming a base for supporting the sash when it is being grooved. At points equally removed from opposite ends of the lid, said lid and the strip 4 are cut through to provide slots 5 extending parallel with the ends of the lid. Mounted on top of the stri p 4 at the rear side thereof is a metal guide bar 6, which has counterfsunlr screws 7 extending through the same from the top and through the lots 5 (see Figure 5), each of which screws is provided atits lower end with a washer 8 and a nut 9. By looseningl the nuts 9, the guide bar 6 can be adjusted in position on the strip 4and then secured in such adjusted position by tightening` said nuts. Ceir tally ol the strip 4 and near the rear edge thereof, said strip and the lid 2 are cut through to provide a slot 10, entendiug longitudinally of the lid (Figures 1 and 6), through which projects the upper side oi a circular saw 11, which is mounted ou the outer end of the shaft 12 of an electric motor `This motor is secured to the tioor ot the casing 1, as by means ot bolts 14. Mounted on a cross-piece 1G near one end of the box Iis a rnvitch 17, which is connected to the motor by means of conductors 1S. Leading from the switch 17 is a flexible conductor 1.9 provided at its outer end with an ordinary plug 20 `for connection vwith an electric light socket. The end ojl the 'casing at which thc switch is loc-ated is centrally apertured, as indicated at 21 (Figure 4) to permit a turnbutton 22 on the switch 17 toA project through said aperture. The material of the end et the `casing` 1s preferably reamed out around the opening1 21, as indicated at 23 in Figures 3 and 4, to provide a space `for the operation oi the turn-button, thus obviating.having the latter project beyond the surface of the end et the casing. The crosspiece 16 and the adj acont end ot the casing 1 are groovcd, as inf dicated at 24, (Figure 4) to receive the conductor 19, so 'that the lid 2 may be firmly closed. Corresponding grooves 25 are termed in said cross-piece and the end ot the casing` near the front end oft the latter, which permit the conductor 19 to be bent upon itself and coiled up in the casing 1 with part of the conductor resting in these grooves and another part restingl in the grooves 24. This arrangement permits the lid to be closed and locked secured in the closed position, as by keepers 26, when the device is not in use or is being carried about. In this position of the parts, a portion of the conductor 19 will project from the end of the casing, as shown in Figures 1, 2, and 4.
The above described .means of arranging for Dit the disposition vof the conductor 19 is preferred because oi' the tacit that the conductor is given 'a very tight tit in the grooves 211 and is not ordinarily removed therefrom. By this means, I prevent :movement of .the conductor at the point of its connection with the switch 17, and also obviate wear of the insulation which would result from constantly placing the conductor into 'and removing it fromthe grooves 24. The additional grooves are, therefore, necessary `to permit the portion ot' the lconductor projecting beyond the casing Vto 'be inserted the box and the lid to be rljnly closed. @ther ways of arranging the-conductor could, of course, be employed. The trontof the-ease is :provided witha handle 27, by meansof which it may be carried about, andits upper-side is recessed'and provided with a Ihood 28 covering the recess to form a housing for the upper part of thc motor. Y Y I In operation, the windev7 sash is removed from t-he frame and placed with its bottom restingon the stripft and one of its sides flush with the side'ofthebar or guide 6. T he plug 20 'having been inserted in an elect-ric "light socket and the lsaw 11 lbeing in operation, the sash is moved along the guide bar 6 into engagement with the saw 11, which operates to cutV a groove `cent-rally of the bottom of the sash and Elongitudinal'ly thereof.
The device isnt-course, carried by the operator to the various places Where he is applying Weatherstrips -to theW-indows, and affords very rapid Vmeans of grooving the bottom rail of a window sash as compared with the hand implements commonly employed for that purpose.v In addition, it atlords a more @cleanly method of procedure, in that all of the saw-dust is caught by the box ork casing 1 and is thus prevented from being scattered over the floor oft the 4room Where the sash is lbeing grooved.
