SAVVING DEVICE.

Application filed July 5, 1921. Serial No. 482,380,

T o ZZ 101mm it may corwe'm:

Be it known that I, Psncv L. Bunnies- Lnr, a citizen of the United States, residing :it Orlando, in the county of Orange and State of Florida` have invented certain new and useful Improvements in Sewing Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention. such :is will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sawing machines and devices, and aims to provide a novel and improved porthble sawing device adapted to be driven by a flexible operating mechanism, `und adapted especially for use as an attachment to the flexible operating mechanism disclosed in my copending; application tiled May 17, 19:21, Serial No. 4765,41?, (Patent No. 1.424.148 granted Aug. l. 1922).

Another object of the invention is the provision of such :i device comprising novel means for mounting: a circular or dish' saw in order that the cut u-.ade can he regulated. including means for regulating the depth of the cut, mearu` for regul ting the. angleof the cut for either a square or miter cut, and means for malinsr thc cut parallel with an edge of theJ board or object at a predetermined distance therefrom.

A further object is the provision of a novel detachable connection between the dericc and drivin..r or operating mechanism for the convenient and efficient assemblage and separation thereof, and enabling other dei ices or attachments to be used interchange ably with the sawing;r device, using the same driving mechanism for all.

A still further obiect is the provision of such a device nhich is useful for sawing Wood, either across` with or at an angle to the grain, with a square or reiter cut, in order to supply the requirements for which ordinary hand saws are used. and the device havingV novi-l and improved features of construction to enhance the utility and clliciency thereof for the intended purposes.

The invention has for another ohject to PI-iiile n powendriven saw mounted and carried bia device which can be convenient ly manipulated manually for doing vw wus kinds of sawing with ease and dispatch, and th: dericc inciudinf: adjustments to i "f" late the cuts triade in order to comply witg, various conditions required.

With the foregoing and other objects in View, which will be understood as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it. being understood that changes can be made within the scope ot' what is claimed, Without departing from the spirit of the invention.

The initiation .is illustrated in the accompaii'ijyingjr drawings. wherein z- Figure 1 is a side elevation of the device, with the driving mechanism removed, and showing the gate bar in a partly open position in dotted lines.

Fig. :3 is a side elevation from the opposite direi-tion, showincr the gate bar swung open iu dotted lines and partly broken away.

Fig. il is a bottom plan view of the device, with the driving mechanism removed.

Fig. l an end view.

Fig. is a fragmentary end view looking from the opposite direc-tion.

Fin. il a vertical section on the line 6-6 if Fig. with the driving mechanism attached.

The device comprises a hase or slide 7 to slide on the surface of the hoard or other ohiect worked on. and including the opposite ends tl and it connected by an integral longitudiual side har 1l). The end 9 has a stuli 11 projecfiin,r therefrom toward the end S at that side opposite. to the bar 10, and a gate har 12 is hinged. as at 13, to the stuh 1l to swing downwardly and upwardly. The har li is provided at its free end with :i thinned `portion 14 to fit snugly under a stub 15 projectingr from the end 8 of the base toward tlu stub ll. said portion 14 and Stub 15 overlapping with :i scarf joint. When they har 12 is swung down, as indicated in dotted lines in Fig. this leaves a clearance or gate opening hntween the stubs 11 and 15, and means is provided for fastening;r the har 12 to the end 8. whereby said bar 12 assists in ,supporting :ind guiding the base, and also rigidi; connects the ends 8 and 9 at that side opposite to the har 10. Thus, the p0rtion l-1 has an extension lf3 to enter a notch li' in the lfiwer edge ot the end 8, thereby scarlying fhe liai- 12 against transverse disnicht. and the extension lhasan invert1 J-,-.h ancd hitchsnpport 1S in which a latch if is .-lidaifle longitudinally of the har grec 050-.

lessees end S, when the bnr 1Q. is swung to closed position. The latch bolt 19 has n. knol l on its outer end, for retractil) f the latch bolt by hand, and a coiled expansion s wing 22 is disposed or, the latch bult within t e support 18 und is conliiied between said support and a pin 223 or other element secured to the latch bolt, whereby to project the latch bolt into the notch 2.0. This latch bolt will therefore hold the bar 1i. in its closed position, so that tlm bars l() and 12 will provide shoes or runners to slide on the surface of tlie wood.

A. miter frame or member 24 is provided lor regulating the angle of the cut made, and its lower portion is disposed longitudinally between the longitudinal bars o:- runners 10 and 12 of the base, and said member 2,4 extends upwardly from the base. The ends of the member 24 are )ivoted to the ends of the base, and, as siown, the ends of the member .24 abut the ends S :ind

9 of oase, und are pvotecl thereto by means of pivot screws 25 extending inwardly through the ends S and 9 into the ends of the member 9A, thus mounting said memi ber for transverse swinging or tilting ad justment from one side to the other abouty a longitudinal axis.

The member 9A has a ,fluide or slideway 27 perpendicular with the lower portion or axis of said member, and :i depth slide ir block 46 is slid-ble upwardly und downward ly in the guide or slot 2T, und luis :i circular opening or bore 2S extending therethrough transversely of the base 7 und member EM. An upstancling screw sioni 2i) is scoured in the upper portion of the. slide L10 und lisser@ Slldably through the npfser'portion of tlm member f2.4, und an adjusting nut SO is threaded on Suid stem and bears on tlie niembe1""".`: l. A. look nut 3l is tlireaflel'l on tlm stem below the upper portion of tin; invinber 2.4, and a. lock nut 32 can be` thi-wurd on the upper terminal of the stein to lugar on. the nut. SO, in order that. when tlm. nu?. 30 is rotated to adjust the slide 40 to the, desired vertical position with respect to time base 7, the nuts 3l and 33 can be tightened for retaining the adjustment.

The engl 8 of the baise has an arnuzite slot 33 receiving a clumpin in the corresponding en screw 2&4 eng-:aguil whereby of the member 14, the member 2A can be clninped in its various angular adnistnients.

In order to facilitate the adjustment of tlieinonilwr 2l to dillerent angles, a

)ointer or inilox 46 is secured. to said en portion oi the member 24 und is movable over mitm` or ile raduations 4T un the end 8 of the brise A n andle 35 issccurecl on the member 24 near one end thereof, for oonvenirntly sli ling the device nlengthwise [or the sawing operation.

The Suv: or equivalent implement is rw tateil lx1. u driving or operating mechanism which is assembled with the slide 40. As shown in Fig. 6 the Flexible operating mechanism, iis disclosed in the aforesaid applica tion, is used, and only the freelymovable termin-ul portion' of suoli mechanism is shown (the sinne reference elifiraters being used as -in suoli application). Suc-l1 mechanism includes n termimil yoke 2G which has bush-` ings SLG and' 36 secured in the terminals thereof, and u tubular spindle or arbor 3T is fitted for rotation in said bushings. A pulley wheel 42 is secured on the spindle 37 between said bushings for retaining the spindle in place, and :i bolt 14 passes around sfiifl pulley wheel for rotating said spindle, and is guided between rollers 45. The' maw drei m' sliuft 518 on which the saw or imple` ment 42? is secured, is received by the tubular :spindle 311 und suifl spindle has a screwliireetloll portion 'f :it that end Opry-:osito to the smv into which the screw threaded terminal 3S of the mandrel or shaft 38 is surewml. for fastening said shaft to the spindle lhs slifift has u collar 23S thereon to honi' ziliminst that end of tlie'spinclle or possi-.fi to tiie screw-threaded enfl, for fas 10min; tlw sliuft securely toi'the spindle, und tin, :ein 13 is secured on suid shaft afl`sicent to the millar FS.
