To @ZZ whom, it may concern:

Be it known that I, THERON S. CARROLL, a citizen of the United States, residing in W insted, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Wood-Sawing Machines, of which the following is a specification.

Thisinvention relates to machines for sawing wood, and has for one object a machine of the class specified embodying novel features and which is espcially adapted for sawing logs or other work on a taper, but with a minimum'loss ofV stock, to produce, for instance, iiagstaffs, masts for vessels, dre., of proper form.

Other objects of my invention are to provide means whereby the machine may be adjusted to stock of different sizes and also to provide means for adapting the machine for cutting objects of different tapers, as may be required; and a further object is to provide an improved construction of work-sustaining devices, as will be hereinafter described and as illustrated in the accompanying drawings, in which-#- Figure 1 is a plan View ot' a machine constructed in' accordance with myinvent-ion. Fig. 2 is a side View of the same. Fig. 3 is a top view of the head-stocl employed in connection with the table and adapted for holding the logs, and Fig. 4 is a side viewthereof. Fig. 5 is a top view of the tail-stock cooperating with the head-stock, and Fig. 6 is a side view of the same. Fig. 7 is a transverse section of the table on line 7 7, Fig. 1, on an enlarged scale. Fig. 8 represents a plan view of a rest for sustaining the log, and Fig. 9 is a partial front View of the table and rest.

Similar characters of reference designatel vided on the table T for securely holding the log during the sawing operation, such means consisting, substantially, of a head-stock H and a tail-stock I, the former of which is preferablyadjustable at the right-hand end of the table T, while the tail-stock may have considerable longitudinal adjustment adjacent the left-hand end of the table, as clearly shown in Fig. 1. The table T is preferably formed of a framework consisting of the side pieces 1l and 12, joined at their ends and at intermediate points by ties 13 to form a rigid structure.

Located adjaceht to the head and tail stocks and also at a point intermediate the same are rests R, upon which the log L may be placed and supported preparatory to its engagement with the centers or spindles carried by the head and tail stocks. The construction of the rests R is clearly shown in Figs. 7 to 9, inclusive, in which 14 designates a block supported on the upper side of the table T, said block being provided with apertures 14', adapted to receive racks, such as 15 15', the upper ends of which are reduced, as at 16 16', to support a platen 17. Centrally journaled in the block 14 and between said racks l5 15' is a shaft 18, having a worm-gear 19 fixed `thereon and also carrying a worm 20, adapted It will to engage the racks above mentioned. therefore be seen that when the spindle 18 is rotated both racks 15 15 will be either raised or lowered simultaneously, and in this manner they will elevate or depress the platen 17, upon which the log rests. The worm-gear 19 is engaged by a worm, as indicated by 21, Fig. 8, mounted upon a spindle 22, having a squared portion 23, to which a wrench may be applied for imparting rotary motion to the same, and in order to cause all of the platens y17 to be adjusted simultaneously I vpreferably provide each ofthe blocks 14 with aprojection 24, having a bearing 25, in whichis journaled the hub 26 of a bevel-gear 27,' which is in mesh with a similar bevel-gear 28,

mounted upon the above-mentioned spindle 22 and secured thereto by aset-screw, (see Fig. 7 so that when any one of the spindles IOO 22. is rotated rotary movement will be imn parted to the bevel-gear 27, which in turn will actuate the shaft 29, to which similar gears are secured for the purpose of operating the platens of the entire series of rests R, as will be readily understood, said shaft 29 being suitably supported on the table rl`--as, for instance, by means of bearings 30.

The head-stock H is shown in Figs. 3 and 4- of the drawings and embodies a plate 3l, supported on suitable guides or ways 32 and 32', secured upon the upper side of the tableframe and on which said plate 3l may be held-as, for instance, by clamp-serews 33. The head-stock further comprises a slide member 34, which is mounted in ways 35 of plate 3l, in which ways said slide may be moved laterally of the table and plate 3l by means of a screw 36, in threaded engagement with a nut 37 at the under side of the slide 34, such screw being rotatively supported in a lug 38, projecting from the upper side of the plate 3l, and having a collar 39 and hand- Wheei 40, by the hub of which and said collar 39 said screw 36 is prevented from longitudinal movement in said lug 38. When hand-wheel 40 is rotated, the slide 34 is moved laterally of the table to increase or decrease the distance between a center or spindle 4l, carried in such slide, and the face of the saw S. This spindle 4l constitutes a centering device for one end of the log to be sawcd and may be provided with a disk 42, having a series of pins 43, which when the work is centered on said spindle 41 will enter the end of the log and cause the same to turn with said spindle when the latter is rotated, while, on the other hand, the pins 43 also constitute means for preventing the rotation of the log when spindle 4l is at rest.

Secured to the outer end of spindle 4l is a worm-gear 45, in engagement with a worm 4G, mounted on a suitable spindle 47, which has a squared end 48, adapted to receive a wrench for imparting rotary movement thereto, and which movement will result in rotating said spindle 41, the disk 42, and pins 43. The spindle 4l is preferably mounted in a block 49, which may be vertically adjusted by a screw 50, said block being provided with ears 51, serving as bearings for the above-mentioned spindle 47, so that when said block 49 is adjusted the worm 46 and other parts carried by the block will be bodily moved therewith.

When it is remembered that the saw S is mounted in a fixed frame and that the line of travel of table T is at a predetermined distance from said saw,it will be seen that when the slide 34- is moved laterally to the table in a rearward direction the distance between the axis of the center-spindle -tl and the. face of the saw will be increased and that consequently the thickness of the slab removed from the log or other work may be controlled as desired, and in order to aid the operator in setting the slide 34 to produce a log of the desired size at that end an index 52 is provided on said slide, the points of which may be made to register with a zero-mark 53 on the bed-plate 3l.

Referring to Figs. 5 and 6, in which the tail-stock I is illustrated in detail, it will be seen that the construction of the latteris very similar to that of the head-stock H and that it embodies a bed-plate 54, movable longitudinally on ways 55and 55 of table T and has mounted thereon a slide 56, to which a reciprocatory motion laterally of the table may be imparted by means of a screw 57, provided with a collar 5S and a hand-wheel 59, said screw being journaled in a lug 60, which will serve to preventlongitudinal movement of the screw 57 while it is in threaded engagement with a nut 6l,provided on the under side of the slide 56. Adjustably mounted on this slide 56 is a post 62, which may be secured to said slide by bolts 63, adapted to enter a series of screw-threaded apertures 64, and the foot portion 62 of said post 62 is provided with slots 65 to permit a limited adjustment of said post relative to the slide 56. An index 67 is provided on the slide 56 and registers with the zero-mark GS on thc bed-plate 54, serving as a means foradjusting the slide 56 to correspond with the position of the slide 34 of the head-stock.

In Figs. 5 and 6 of the drawings the post 62 is shown provided with an index 69, to bc read in conjunction with the zero-mark on the slide 56 for the purpose of determining the line of taper or cnt in a log, as will hereinafter appear. The post G2 is provided with vertical guides 7l, which engage a block 72, carryingacenterspindle 73,inscrew-threaded engagement therewith and adapted to be adjusted longitudinally therein, while a checknut 74 may serve to retain said center-spindle 73 in adjusted position.

It should be noted that when the

indexes

67 and 52 on the

slides

56 and 34, respectively, correspond and when the zero-

marks

69 and 70 are in alinement the axes of the

spindles

73 and 41 are in alinement with each other and in parallelism with the movement of the table, and hence it will be understood that when the post 62 is shifted on the slide 56 and toward the saw the distance between the center line of the spindle 73 and the side of the saw'S will be decreased and that therefore the log will be cut on a taper, since the distance from the center line of the spindle 4l is greater than the distance between the center line of the tail-stock spindle 73 and the face of said saw.

The block 72 may be vertically adjusted on the ways 7l, above mentioned, by means of a screw 75, in threaded engagement therewith, the vertical adjustments of said

blocks

72 and 49 being provided to permit the log after it has once been cut by the saw and its cut face brought lowcrmost to rest on all of the rests R during the succeeding cutting operations.A Said restsRR serve as steady-rests to sustain the log or other work and prevent the same from sagging, and while said rests are preferably shown as simultaneously adjustable, yet each may have an independent IIO adjustment without departing from my invention, and this could readily be 'aecomplished in the construction shown by loosening the restraining set-screw of the particular gear 28 and then adjusting the rest independently to tit an inequality in the work by applying a Wrench to the squared portion 23 and subsequently turning the spindle in proper direction. v

It is distinctly to be understood that an kind of saw suitable for the purpose may be employed and that the invention is not limited to the circular saw shown and described.
