STEINMEYER WOODWORKING MACHINE Filed Sept. 6, 1952 4 Sheets-Sheet 4 Inventor %ZZ21277& $2 6232: a er Patented Jan. 24, 1933 OFFECE WILLIAM STEIN MEYER, OF ELGIN, ILLINOIS WOODWORKIN G MACHINE Application filed September This invention relates to Wood working machines and is especially directed to machines of the hand power type designed for use in conjunction with Weatherstripping operations for the purpose of grooving or routing sashes, doors or the like as is now required for the application of metal Weatherstripping to sashes, doors or the like and to perform such operation in a quick, convenient and economical manner and by means of which the output of the machine is materially increased over the ordinary type of hand operating machine, less labor being required in grooving or routing the window sash, door or the like, and the doing of the work with greater perfection and accuracy.

The invention together with its numerous objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is an elevatio-nal view of the machine, the same being shown when used for grooving purposes.

Figure 2 is a side elevational view thereof.

Figure 3 is a view illustrating the application of the machine to a window sash.

Figure 1 is a view similar to Figure 2 but illustrating the manner of using the machine for routing purposes.

Figures 5 and 6 are sectional views taken substantially on the lines 55 and 66 respectively of Figure 2.

Figures 7, 8 and 9 are sectional views taken substantially on the lines 77, 88 and 99 of Figure 3.

Figure 10 is a perspective view of a pivoted guide member.

Figure 11 is a fragmentary sectional elevational view taken through a portion of a sash showing the upper member of the sash after a completion of the routing operation.

\Vith reference more in detail to the draw- 5 ings it Will be seen that my improved machine in the preferred embodiment thereof comprises broadly a frame 1, a carriage 2 mounted on the frame for longitudinal :9 travel, a motor support 3 pivotally mounted on the carriage and adapted to be angularly 6, 1932. Serial N0. 631,925.

adjusted relative thereto, an electric motor 4- and a cutter 5. y

The frame comprises a pair of relatively spaced parallel longitudinal bars or rods 6, and on each end of each lOCli 6 there is mounted for longitudinal movement an attaching bracket 7 and the brackets 7 at corresponding ends of the bars 6 are connected by cross bars 8.

As will be seen from a study of Figure 7 each of the brackets 7 comprises a body portion extending at a suitable angle to a bar 6 and provided at one end with an integral sleeve 9 through the bore of which a rod 6 extends, and the screw threadedly engaged with the sleeve 9 is an adjusting screw 10 arranged to engage a. bar 6 for holding the bracket 7 at the desired adjustment.

At its free end the body of the bracket 7 is provided With an L-shaped notch to provide angularly arranged lugs 11, 12, of which the lug 11 is adapted to flatly engage a sash member 13 at one side of the sash, and the other lug 12 is adapted to overlie and extend u in parallelism to the free outer edge or face 79 of the member 13 of the sash as shown in Figure 7.

The lug 12 has threadedly engaged therewith a screw 14: that is adapted to engage the member 13 of the sash as shown, while the lug 11 has integral therewith an apertured flange 15 with which is threadedly engaged a bolt 16 passing through one end of a clamping plate 17, which plate 17 is adapted to engage the inner edge of the member 13 of the sash at one side of the pane 18, and as apparent, when the brackets 7 are thus engaged with relatively opposite members 13 of the window sash 19 the said frame 1 will be fixedly supported on the sash and extend transversely 9 thereof as shown in Figure 3.

The carriage 2 comprises a plate like body 20 provided on its top side with a longitudinal groove, and on its under side'and adjacent relatively opposite ends with pairs of apertured lugs 21 extending transversely thereof to receive the rods 6 as will be clear from a study of Figures 8 and 9.

The sides of the groove in the top of the plate 20 are provided on their inner faces medium of an adjustment screw or bolt 25 that is rotatably supported as indicated generally at 26 on the upturned end of an arm 27 projecting from'one end of the carriage 20, and this screw 25 has screw threadedengagement with a lug 28 provided onone end of the slide or platform 23. Obviously by r0 'tating'the screw'25 the platform 23 may be readily shifted in the desired direction longitudinally of the channel in carriage 20.

On that end of the platform 20 remote from the lug 28 there are provided ears 29 receiving a pivot bolt 30, and the bolt 30 also extends through a pair of ears 31 provided on the lower end of a combined guide and sup: porting member designated generally by the reference character 32. As'shown in Figure 10 the ears 31 on'their inner side are provided I with ratchet teeth or otherwise roughened as at 33 to cooperate with correspondingly roughened faces on the lugs 29 and thereby assist foldable braces 34 in supporting the member 32 at the desired angular adjustment relative to the platform 23 The member 32 comprises sides 35 on the lower ends of which are formed the aforementioned ears 31 and the upper ends of which are connected by a web that is extended and apertured as at 36 to provide a supporting means for an adjusting screw 37.

On the inner faces of the sides 35 are grooves 38, and constrained to shift between the sides 35 is a block or slide 39 provided with tongues or ribs 40 engaging the grooves '38. The slide or block 39 is also provided with an apertured lug 41 with which is threadedly engaged the screw 37, so that obviously by rotating the screw in the proper direction a slide 39 may be raised or lowered, or in other words shifted longitudinally of the number 32 as found desirable.

Suitably connected with the block 39, as by being integral therewith is a split clamping ring 42 that embraces and secures to the block 39 the electric motor 4.

intermediate the ends of the platform. The

7 sections 34a, 34?) are pivotally connected together through the medium of a bolt 45 with which is threadedly engaged a thumb nut 46, and obviously by tightening the thumb nuts 46, the sections 34a, 346 may be secured at the desired angular adjustment relative to one another and thereby brace and support the member 32 at its desired angular adjustment relative to the platform 23 as will be clear from a study of Figures and 8.

As is well known in the art, when weather stripping a window with metal Weatherstrip, metal strips provided with ribs are secured to the inner side of the vertical members of the window frame and also to the window sill requiring agrooving of the side rails and lower rail of the lower window sash and the side rails of the upper window sash, while the lower rail of the upper window sash, and the top rail of the lower window sash are routed on one side thereof as suggested in Figure 11 for receiving strips of metal Weatherstripping so constructed that when the window is closed such strips coact to completely seal the space between the lower rail of the upper window sash and the upper rail of the lower window sash.

In using the present invention, both the the window sashes may be effected, and for grooving purposes there IS suitably connected with the armature shaft of the motor-4 a cutter (S of the character shown in Figures 1 and 2, while for routing purposes a cutter of the character shown at F igure4 is used. For groovlng purposes the frame 1, 1f 1t is desired to groove a side rail 13, is, of

i course, extended longitudinally of the window sash, while, and as shown in F igure3,

if it is desired to groove the lower rail 13a of the lower window sash, the frame 1 is so a supported on the sash as to extend transversely thereof. Assuming that it is desired to groove the lower rail 13a the frame 1 is sup-' motor when viewed in Figures 1 and 2, is, disposed substantially at right angles to the sash 19 so that the cutter 5 is suitably engaged with the rail, and obviously in carrying out the grooving operation the carriage 2 is moved longitudinally of the frame 1 from one end to the other of the sash rail, and drive being transmitted to the cutter 5 from the motor 4 a grooving of the rail longitudinally thereof is easily accomplished. Obviously by adjusting the block 39 the groove made by the cutter 5 and designated by the reference character 47 may be formed in the under side of the rail adjacent either the front or rear face thereof or at any point midway between said faces.

For routing purposes the cutter shown in n f grooving and routing of the proper rails of Figure 4 is substituted for the cutter shown in Figures 1 and 2, and since in routing oper ation the groove formed is cut on a bias, the member 35 is secured at the desired and necessary angular relation with respect to the platform 23 and the plane of the window sash 19 as shown in Figure 4:, the adjusting of the member 32 being effected as hereinbefore stated.

In either grooving or routing operations the depth of the cut made may be easily regulated by properly adjusting the platform 23 relative to the carriage member 20, thus permitting such an adjustment of the depth of the out without requiring a shifting of the frame 1.
