TENONlNG-MACHINE.

SEECIFIGATIOII forming part of Letters Patent N 0. 408,352, dated August 6, 1889.

Application filed March 29, 1888. Serial No. 268,730. (No model.)

To all whom it may concern:

Be it known that l, OSCAR MCCULLOUGH, a citizen of the United States, residing at WVinona, in the county of \Vinona and State of Minnesota, have invented certain new and useful Improvements in Tenoning-Nlachines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to to which it appertains to make and use the same.

This invention relates to improved attachments, which are applicable to either the wellknown wood-frame or to the metal-frame ten- I 5 oning-machinesuch as shown, for instance, in Patent No. 115,603, dated June 6, 1871.

The objects of the improvements or attachments are, first, to enable the operator to form sash-bar tenons for check or lip rail sasl1,which 2o difler at the shoulders, without a resetting of the tenoning machine, as heretofore required, and to finish each bar at one operation,'and, second, to finish so-called sash-muntins by cutting the tenon the eXact required length after being formed and at one operation.

The improved attachment will be fully understood from the following description, when taken in connection with the annexed drawings, in which Figure 1 is an elevation of a tenoning-machine with a wooden frame, showing my improvements attached thereto, and as shown enlarged in Figs. 3, 4, and 5. Fig. 2 is a similar View of a tenoning-machine with a metal frame, showing the same improvement attached. Fig. is a top or plan view of the attachment. Fig. a is a front elevation of the same. Fig. 5 is an elevation of one end of Fig. 4. Fig. 0 is a cross-section of a dado cutter-head to be used as a substitute at option for the saws shown in Figs. 4, 5, and 7. Fig. '7 is a view of one side of a combined cut ting and grooving device, shown by edge views in Figs. 3 and 1. Fig. 8 is a detail plan View of one end of the bottom sash-bar after the tenon is formed, as usual, by the cutters of the tenoning-machine. Fig. 9 is a detail plan view of the bar shown in Fig. 8 after passing through the attachment, the portion removed being shown in dotted lines. Fig. 10

is a detail plan view of one end of the top sash-bar after the usual tenon is formed, and

a portion at one side shown in dotted lines removed by the attachment. Fig. .11 is a detail plan view of one end of a finished muntin 5 5 with the tenon cut to the proper length. Fig.

12 is a similar view of the muntin shown in Fig. 11 previous to the shortening of the tenon. Fig. 13 is a perspective View of a tenoningmachine with my attachment applied, the va- 6o rious details common to tenoning-machines being omitted.

In the annexed drawings, Fig. 1, I have represented the main parts of a wood-frametenoning machine, and in Fig. 2 I have shown the main parts of a met-al-frame-tenoning machine, constructed substantially as shown in the patent before referred to.

In both machines I) Z) designate cutterheads; 0, a belt-tightener; a, the counter and 7c pulley; d, the cope-head; e, a vertical shaft;

f, a driver-belt pulley thereon, and g, a driverbelt pulley for the shaft of the cope-head (Z. These parts are old and well known, and for this reason do not need a more full and clear description. The carriage upon which the wood is placed while the tenon is formed and upon which it is carried until its final completion by my attachment is not shown in the annexed drawings, except in Fig. 13, where it is designated by the letter 0, being common to all tenoning-machines and identical in principle, being arranged to move horizontally from left to right, and vice versa, as clearly shown in the patent before mentioned, so that the sash-bar first passes between the cutter-heads I) Z), which form the tenons s or 5, Figs. 8 and 10; then past the cope-head d,wh ich gives the ogee form to the end of the side 8', Figs. 8 and 9, as usual, and. then, if necessary, over the 0 saws or cutter-head running on the lower bracket or under the saws or cutter-head running on the upper bracket of my improved attachment, which I am now about to describe.

On the vertical shaft 6 are fastened two driving-belt pulleys G G, which, by means of belts suitably applied to pulleys D D, (shown in Fig. 4,) are designed to give rotation to the arbors F F and the saws or cutter-heads thereon. I00

When my attachment (aside from the pulleys G G mentioned, and consisting, primarily, of two double bracketarms B B or four single arms, if preferred, carrying said arbors F F, journaled in boxes, as shown) is .to be affixed to metal-frame-tenoning machines or secured to them by set-screws s s for endwise set and adjustment of these arbors. For effecting aproper vertical adjustment of the face-plate A and the bracket B, slotted boltholes are preferred.

On the ends of said arbors F F are rigidly secured, by flanges h and flanged nuts h,the

rotary cutters O O, which are adjustable laterally by means of collars E E, as shown,,and may respectively consist of a groove-saw t and a spur-saw t, as shown in Fig. 7. In lieu of these cutting devices 0 O, I may substitute cutters of the form shown in Fig. 6 or of any other desired form.

In using the machine containing my im- 7 proved attachment the operator takes a bar,

lays it on the carriage of the machine with the part 3 Fig. 8, uppermost, and, moving the carriage, presents one end of the bar to the cutter b, which forms the tenon s. The carriage is then moved to the cope or cutterhead d, which gives the ogee form to the end of the side 8', as shown in Fig. 8.

Thus far the operation and production of the machine is as usual in sash-makin g to form the end of the sash-bar to fit the upper sash-rail of the upper sash. The bar is then reversed and the end treated in the same manner. However, as the side 5 is too long to fit the lip or shoulder 011 the top sash-rail it has been usual to adjust one of the gutters b to out the said side shorter than the side 5. To obviate such adjustment of the cutters b is the object of my attachment. The lower cutter 0 having been properly adjusted, the carriage is moved forward until said cutter reduces the side .9 as shown in dotted lines, Fig. 9. The same procedure is then had with the bottom sash-bar. The saws or cutterheads on top arbor F having been adjusted laterally to place, by adjusting the collars E E the first tenon is made on the machine, as before, and illustrated in Fig. 8. The bar is then reversed, placed against a stop, (designated in Fig. 13 by C and the second tenon made precisely as the first, and, without stopping the operation, the carriage is moved forward carrying the bar under and beyond the saws or cutter head 0, running on the upper bracket of the improved attachment. The bottom sash-bar is thus finished, as shown in Fig. 9. The tenon is shown at s", the reduced side at and the other side at 5 Further, in using my attachment for forming tenons on sash-muntins the tenon is formed on the machine in the usual manner, passing the cutter and cope-heads of said machine, (illustrated in Fig. 12,) and without stopping operation the carriage holding the muntin stuff is moved forward and past the saws or cutterheads running on either upper or lower brackets of my attachment, thus cutting the tenon the exact required length and in the same operation. The finished end of the muntin isillustrated in Fig. 11.

Having described my invention, what I claim is 1. In a machine for forming sash-bar tenons for check or lip rail sash, the combination of the rotative cutters b b and rotative cutters O O, with the interposed cope-head (1, arranged in the relation described, and a reciprocating carriage adapted to support and guide the stuff, as specified.

2. In a machine for forming sash-bar tenons for check or lip rail sash, the combination of the rotative cutters b b, the rotative cutters C 0, having endwise-adjustable shafts, the verticallyadjustable bracket-bearings for said shafts, the cope-head (1, arranged as described, and a reciprocating carriage adapted to support and guide the stuff, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

OSCAR MOCULLOUGH.
