SAWING-MACHINE.

`vision of a gage-board, which is so applied to the movable top of the machine by peculiar mechanism that it is adaptedto be set at different vertical and horizontal angles as required for different kinds of work.

Another special feature of novelty and improvement is the provision Of a traveling carrier for supportingthe fr ee endsof ilong.

boards or other pieces oflnmber whilebeing sawed, the carrier and top beingso connected that they move together. The carrier is adapted to be extended at different vdistances from the movable top .of the machine to adapt it to accommodate lumber of different lengths.

The details of construction, arrangement, and operation are as hereinafter described with reference to the accompanying drawings, three sheets, in whichf. V-

Figure 1 is a perspective view of the main frame of my improved machine. Fig. 2 is a perspective view of the movable carrier. Fig. 3 is a perspective view of the movable top provided with the adjustable gage-board and the lumber-carrier connected with said top.

Fig. 3 is a detail section, enlarged, Online 3f 3n of Fig. Fig. lis an enlarged crosssection of the lumber-carrier- Figs. 5 and 6 are perspective views of clamps forming part of the mechanism for adjusting and holding the gage-boardat l'different angles. Fig. 7 is a verticalcross-section of-the machine, the line of section being,in fr ont of one end of the mainframe. Fig. 8 isja perspective view of one of the adjustable stops for limiting the movement of `thesliding top of the machine. Figs. 9 and 10 are respectively end and plan views illustrating the adjustment of the gageboard.

`Referring in the iirst instance to Fig. l, A indicates the main frame of my sawingmachine, the same comprising horizontal sills 1962.5- lsgriaiiroizaaso. (Nontdei.)

' uprights or standards' 2, 4top and-bottom bars 3 3, andulongitudinal bars 4 4, vsecured upon the bars 3. A circular saw B ismounted non.an arbor 5, which }is ,drive,n vfrom theshaft 6, having its bearings inthe lower portion of the frame. The said shaft 6 is provided with a fly-wheel 7 and a large band-pulley 8, from which a band or belt 9 runs to a similar pulley 8j? onthe saw-shaft 5. 10 is applied to the drive-shaft 6 to provide for the application of power. A rectangular -table or top C (see Figs. 3 and 7) is applied to the top of the frame A. lt is held in due position and` is yadapted to be moved easily .or with the application of very slight force by the provision of antifriction-rollers 11 and 12that is to say, such rollers are arranged onlthe upper side of the top longitudinal bars .ll-anda, also on the outer side of the bar 4,

vwvhile' the rollers 1 2 are journaled at the ends of "plate-springs 13, which are suitably attached to the bar 4J. It will be understood thatV the side rollers work in contact with the pendent flange c of the top C and that the springs 13 provide an easy bearing for the rollers 12 and hold the top C in close working contact with the side rollers 11. By compressing the springs 13 the lateral pressure on the flange c of the top is relieved, so that the top may be removed without difficulty whenever occasion may require. The top C is provided with an extended lengthwise slot c' l(see Fig. 3) for accommodation of the saw B, and Ifprovide each end of the top frame with an adjustable stop 14 (see Figs. 1

and 8) for limiting the lengthwise movement .as follows: Two rods or bars 18 are journaled in suitable holders or bearings in vertical position on the rear side of the board D. The central portions of these bars 18 are pro Asprocket-wheel Y IOO vided with clamps 19, (see Fig. 3,) which serve to hold other vertical bars 20. The lower ends of the rods 2O are connected by rightangular rods 21 with another rod 22, which is slidable in an eye 23, forming a fixed attachment of the top C. The rod 21 (see Fig. 6) is secured to the rod 22 by clamp 26, consisting of a screw-eye and nut. The upper end of the rod 2O is connected with the horizontal rod 2l by a diagonal rod 25, whose lower end is secured adj ustably by a clamp 24, (see Figs. B and 5,) the said clamp consisting of a U- shaped screw-bolt and nuts applied to its threaded ends, a washer 27 being arranged between the rods 21 25. The'diagonal rods 25 are jointed at as shown in Fig. It will be seen that this mechanism is adapted to be easily and quickly manipulated for adjusting and supporting the gage-board D at different vertical and horizontal angles, as indicated in Figs. 9 and l0. To illustrate, the gageboard D may be inclined at a vertical angle, as shown in Fig. 9, for the purpose of enabling the machine to be used for cutting bevels on edges of boards, for which purpose the rods 2 are slid back in the clamps 23, attached to the top C, and the diagonal brace-rods 25 may be adjusted backward on the rods 21 by looseningthe clamps 24, and, if required, the clamps 26 may also be slid back on the rods 22. Thus by adjustment of the clamps 23 2i 26 a great amplitude of adjustment is provided for. It will be understood that for a slight adjustment it will onlybe necessary to move the clamp 21 backward on the anglerods 2l.

The joint 25 of rods 25 also allows the latter to be bent at a greater or less angle to hold the board D more or less inclined. )Vhcn the rods 25 are so bent, the clamps 2l will hold them securely in such position.

lf it be desired to move the gage D bodily backward from the saw to accommodate board or lumber of increased width or to make a deeper cut in the lumber, the clamps 26 are loosened and slid back 011 the rods 22, or, if necessary, the rods 22 may be also slid backward in the clamps 23. Again, if it be desired to set the gage D at a horizontal angle to the plane of the saw, as illustrated diagrammatically in Fig. 10, then the adjustment is effected by manipulation of one of the two sets of adjusting devices, the other being allowed to remain in its original position and the gage swung on one of the rods 2O as a center. In this manipulation or adjustment the rods 2() and 18 turn together, being held together by the clamps 1f).

It commonlyv occurs that the lumber being sawed requires to be supported at its outer or free end, and for this purpose I provide the wheeled carrier E. (See Figs. 2, 3, i.) The same comprises a box 27, adapted for receiving the end of the board or other piece of lumber, a top or rest board 28, and wheels 29, which run upon a horizontal track 30, that forms an attachment of a cross-bar 3l, supported by adjustable legs or standards 32. Said standards are iixed in a suitable base 33 (see Fig. 3) and are adapted for Vertical eX- tension by means of screw-bolts 34 passing through slots, as shown best in Fig. 2. The carrier proper, 27, is connected with the sliding top C of the machine (see Fig. 3) by means of extensible bars 35. Said bars are formed of two parts, one lapping upon the other and secured together adjustably by means of clamps 36, which allow one part to be slid lengthwise upon the other. The said bars 35 are permanently attached to the machine-top C on one side thereof by means of bolts passing through lugs 37, (See Fig. l0) and are similarly secured to bars 38, forming an attachment of the carrier E. A diagonal bracebar 3.() (see Fig. 3) is applied to the extensible bars 35 at a point adjacent to the carrier E. Said brace 39 is pivoted to one of the extensible bars 35 at one end and has an adjustable attachment at its other end and with the opt posite extensible bar 35. Such adjustmen, is provided for by means of a bolt and slot, as shown. It will be seen that this construction and combination of parts adapts the earrier E to be set at any height that may be required, also to be adjusted at any angle to the machine top C and gage-board D which may be desired. lVhen the board is to be supported by the carrier E, its free end is first laid upon the top 28 and allowed to rest there until the exact adjustment and length are ascertained. When the board is to be cut at a diierent length, the distance of the carrier E from the saw will be accurately determined by means of the usual measuring-pole. Then the free end of the board will be laid in the box E, so as to abut the Vertical wall or end of the same. As shown in Fig. 4, the parts 3S to which the extensible bars 35 are bolted extend beneath the carrier-box 27 and up the outer side of the same, where they are again bent at right angles to adapt them to form bearings for the grooved rollers 29. This construction and arrangement of parts are at once strong, simple, and durable.

It will be seen that the vertical frame supporting the carrier E must be adjusted at different angles to the side of the machine-top C in case the piece of lumber which the carrier supports is being sawed at an angle.

The top C is readily detachable from the frame of the machine and the gage D and its adjusting mechanism are easily removable from the top C. The carrierE and its extensible bars are also adapted for convenient attachment from the top, so that but little time is required to adapt the machine for sawing short or long pieces of lumber.
