Application filed December 15, 1913. Serial No. 806,868. 7

To all whom it may concern:

Be it known that I, FRANK Koons, acitlzen of the United States, residing at Grooville, in the county of Sullivan andState of New York, have invented a new and useful Sawing-lvfachine, of which the following is a specification.

The present mvention appertams to a sawing machine, and aims primarily to provide a novel and improved apparatus for sawing tubular or hollow balusters, table legs, pedestals, newels, pillars, kegs and the like.

A further object of thepresent invention is to provide a machine of the nature indicated, which shall be improved generally in its construction, whereby the operation and utility thereof will be enhanced.

' With the foregoing general objects outlined, and with other objects in view which will be apparent as the nature of the inven tion is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention'herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein Figure 1 is a side elevation of the complete machine, portions being broken away, and portions being shown in section. Figs. 2, 3, e, 5, 6 and 7, are cross sections taken on the lines 2'2, 3-3, 4l.-4, 5-5, 6+6 and. l'7 of Fig. 1. Fig. 8 is an enlarged sectional detail of the platform and saw guide or guard.

In carrying out the present invent1on,

there is provided an upright or vertical guide, embodying a pair of angle iron rails 1 which may be supported in an upright position in any suitable manner, the same being readily secured to a supporting structure, wall, or other object. Themachine alsoineludes a slide or carriage movable along the slide or track, and embodying a pair of side .members 2;, preferably constructed as angle irons, and having certain of their flanges overlappmg the outer sldes of certain ofthe flanges of the guide rails 1, the said flanges. of the side members or angle irons 2 having their edges beveled, and engaging imder thebeveleded'ges of cleats or strips Sseoured to the said flanges of the rails 1, whereby the slide or carriage will be guided for vertical sliding movements along the guide or track. A pair of V-shaped brackets 4 are terminally secured to the rails 1, at the proper points and are provided with suitable bearings or journal boxes 5 at their crotches and which are in verticalalinement. A tubular shaft 6 is journaledlthrough the bearings or boxings 5, and a suitable pulley wheel 7 is keyed upon the shaft 6rbetween the bearings 5.

' The pulley wheel 7 permits the shaft 6 to be belted to a driving shaft, whereby the tubular shaft maybe rotated properly. At its upper end, the tubular shaft 6 is provided with a disk or plate 8, which is preferably bolted to a flangeprovided upon the upper end of the shaft, and which serves as a base for-the saw, the disk or base 8 being provided with a plurality of concentric series of upstanding lugs 9, for accommodating the various diameters i of tubular or cylindrical saws, one of which, is designated by the .numeral 10. It will be apparent that the lower end of the saw 10 may be readily set upon the disk or plate 8 over one series of lugs 9, and maybe bolted or otherwise secured to the said lugs to support the saw in operative position, the upper end of the saw being. toothed. To the lower end of the slide members 2, are attached "the terminals of a V-shaped bracket 13 having a bearing 14 at its crotch, the said. bearing being disposed below and in alinement with the bearings 5. A spindle 15 is slidable through the tubular shaft 6,-and has its lower end clamped or of the rails 1, the bearings 5 having'ducts leading through the shaft 6, and the shaft 6 preferably having apertures communicating with the ducts which convey the lubricant to the spindle 15. -.In thismanner, the wearing surfaces betweenzthe bearings 5 and the shaft 6 will be lubricated, as well as the wearing surfaces between the shaft 6 and the spindle 15.

To the upper ends of the slide members 2 are secured the terminals of the V-shaped tension 21, whereby the yoke and the clamping plate 23 carried thereby may be adjusted vertically. At the upper end of the spindle, there is disposed a platform 25, embodying the angle iron frame 26 attached to the slide members 2, and the flooring or platform proper 27 mounted within "thev frame '26, and having a circular opening 28 concentric with the upper end of the spindle 15. The edge of the opening 28 is rabbeted, for the reception of a ring or annulus 29 having its edges rabbeted, and a second and smaller ring 29 may be seated within the ring 29, as seen in Fig. 8. The ring 29 as illustrated in Fig. 1 has an opening of suiiicient size to permit the saw 10 to pass snugly therethrough. When a larger size of saw is employed, the rin 29 is removed, in which event the opening 28 will accommodate the larger saw. When a smaller size saw is employed, the ring 29 is inserted within the ring 29, to accommodate the smaller saw as will be apparent.

A pair of horizontal or lateral guides orv rails 30 are terminally attached to the slide members 2 intermediate the platform 25 and the upper bracket 20, and a pair of slides 31 are mounted for sliding movements upon the end portions of each guide or rail 30. Clamping arms 32 are carried by the slides 31 of-each pair, and have their ends pointed. and directed toward each other, as clearly seen inFig. 6. An adjusting screw 33 passes through the slides 31 and has right and left handed threads engaging there, spective slides, which will permit the slides to be adjusted to and from'each other by the proper rotation ofithe screw 33, in order that'the clamping arms 32 may be properly adjusted.

The slide or carriage and the parts carried thereby are preferably counter-balanced or poised by means of a counter-weight 34 attached to a cord or flexible element 35- trained over a pulley or guide 36 and at-' tached to the slide or carriage. This will permit the slide or carriage to move vertically freely.

The slide or carriage maybe actuated in any suitableimanner. As illustrated, a cross shaft. 37 is .journaledthrough bearings 38 attached to the rails 1 adjoining the lower .end of the slide or carriage, and provided with a pulley wheel 39 at one end whereby the shaft 37 may be belted to the driving shaft (not shown). The shaft 37 carries gears or pinions 4 0 intermeshing in racks ll attached to the slide members 2 within the elbows thereof. It is apparent that by rotating the shaft 37 in the proper direction, the slide or carriage may be slid downwardly with the proper velocity. I

The feeding shaft 37 may be connected to the driving shaft for feeding the slide or carriage downwardly and independent means may be employed for rapidly or speedily raising the carriage or slide, and to this end a cross shaft 1-2 may be our- Qnaled through bearings 13 carried by the rails 1 and carrying a pulley wheel l-i at.

one end for belting the shaft 42 with the driving shaft. Friction wheels 4-5 may be carried by the shaft 12 to frictionally engage the slide members 2, whereby when the shaft 42 is rotated in the proper direction, the slide or carriage may be quickly or rapidly raised to an elevated position.

Any suitable clutch means may be provided for alternately throwing the counter shafts 37 and 4:2 into engagement with the driving shafhfor reciprocating'the slide or carriage as necessary in the operation of the machine. As a means for discharging the saw dust, as the log or stock is sawed, a fan or blower 11. is mounted on or carried by the bottom of the base or saw; rest 8 and has its blades or, vanes in the form of funnels or scoops with their inner ends communicating through openings 12 provided in the base or disk 8 within the inner series of lugs 9:. 1

The outer ends or mouths of thefan blades open toward the direction in which the disk or base 8 is rotated, whereby theair will be caught by the fan blades and conducted in wardly and upwardly through the openings 12 into the saw.

endwise between the upper end of the spins dle'15' and the clamping member 23, the

clamping member 23 having been previously 1 of the log or stock. The clamping arms'32 of the clamps carried intermediate'the platform 25 and the bracket 20, and between whicharms, the log or stock is placed, are

moved together, through the mediums of the I adjusting screws 33, in order that the tips or free ends of the clamping, arms 32 will tightly engage the opposite sides of the log or stock. Thus,two independent means are provided for clamping or holding thelog or stock, one for holding the ends, and 1 other for holding the sides thereof.

.110. in operation, the log or stock 46 is placed The saw 10 is rotated at the proper speed, by actuating the saw shaft 6 through the medium of the pulley wheel 7 as will be obvious. The slide or carriage, upon which the log or stock has been mounted, is then moved downwardly, the slide or carriage being slid downwardly at the proper speed, so that the upper end of the saw 10will cut into the lower end of the'log or stock. As the log or stock is moved downwardly, the saw will cut its way through the same, and when the log or stock reaches the end of its downward stroke or movement, the outer shell thereof will be completely severed from the inner core. The slide or carriage may then be raised, to raise or extract the log or stock from the saw, it being observed that the shell of the log or stock will be held by the clamping arms 32, while the core of the log or stock will be held by the spindle 15 and clamping member 23. Thus, the shell or tubular portion of the stock will not only be raised from off the saw, but the core or central portion of the log or stock will also be raised therewith. The shell and core may then be removed, by loosening the clamping arms 32 and the clamping member 28. The core thus formed may then be sawed or cut by a smaller size saw, to provide a smaller shell or tubular portion. In this manner, the log or stock may be cut into a plurality of shells, which may be turned 'or otherwise fashioned into balusters, table legs, pedestals, newels, pillars and the like. It is evident that with the various sizes of 1 stock, the rings 29 and 2-9 may be removed and applied from and to theplatform 25 as necessary to guide or guard the saw.

As the log or stock is being fed downwardly over the saw, to be cut or severed, the fan or blower upon the bottom of the saw, disk or base 8 will create .a current of air upwardly through the said base or disk into the saw, and consequently, the air will work its-way through the circular or annular kerf in the log or stock, to clear the kerf or cut of the saw dust. The air being forced upwardly within the saw, will pass upwardly between the inner walls of the kerf and saw, and thence around the teeth of the saw and downwardly between the outer walls of the kerf-and saw. The teeth of the saw are such, as to cut a comparativelywide kerf or slot, in order that the saw dust may be blown or discharged therefrom by the air currents.

The present machine or apparatus has a wide latitude of application, in practice, in-

asmuch as it may be employed for various purposes, and may be constructed in various sizes or proportlons for the various conditions of work to be accomplished.

From the foregoing, taken in connection with the drawings, the advantages and capabilities of the present device will be apparent to those skilled in the art, and further comment is not deemed necessary.

Having thus described the invention what is claimed as new is I 1. In a sawing machine, a rotary tubular saw and a carriage movable longitudinally relative to one another, clamping members carried by the carnage for engaging the ends of the stock, one of the said members an adjustable clamping member carried by the carriage andcooperating with the said spindle to engage the ends of the stock, a guide member carried by the carriage and having an opening to accommodate the saw, and adjustable stock clamping means car ried by the carriage intermediate the guide member and said clamping member.

3. In a sawing machine, a rotary carrier, a tubular saw attached to the carrier, and a fan attached to the carrier and including funnel-shaped blades, the carrier having openings leading from the inner ends of the blades into the saw.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in'the presence of two witnesses.

FRANK KOONS.
