The two from? is a: hollow casting of the irregular form fully represlmled in Figs. 3, 4, 5, consfilnting nofonly a Support for the saw S the intermediary of which the saw is driven by the motor. The saw frame is open at top and closed below by a. removable bottom cover C; and is providcdwith a hand hole.

closed bya suitable cover C (Fig.

Within it are cupped horizontal bearings C for the saw mandrel ant. central cupped vertical bearing C for the vertical spindle D. This spindle is axially arranged with reference to the cylindrical carriage frame A, and is directly driven by the motor; on its lower end is a beveled gear 1,

which meshes with a like gear on the saw mandrel. in this way the saw can be driver.

practically directly from the motor shaft, of which the spindle D is in effect a prolongation. The motor, instead of being vertical, may occupy a horizontal position, as indicated in Fig. 8, in which event, the motor shaft being at right angles to the spindle D, an additional pair of be eled gears 3, 4, at top will be required to connect the motor with the spindle. I prefer, however, the direct drive arrangement shown in the preceding figures and first above described, because the w may be driven from the motor by only a single pair of directly connected gears, and because the rotating saw frame C will revolve abort the axis of the motor shaft as a center.

The otary mosement of the saw frame C is provided for as follows: The. top of the box-like saw frame is cylindrical in formand is provided with an external horizontal annular flange C', which (its and rests upon the shelf A The saw frame is thus supported by the shelf A, and at the same time can be rotated thereon, its flange C moving over the face of the shelf with which it is in contact. The center upon which the saw frame thus turns coincidentwith the axis of revolution of the vertical spindle D; and thus the saw frame may. be rotated independently of the motor and motor carriage to bring the saw into any desired position relatively to the ice to be cut, without in any way disturbing the driving connections between the motor and the saw. In order to thus rotate the saw frame, any suitable means may be employed. The means profor to use as follows: The space above the annular t ange C and included between the vertical wills of the saw frame and the motor carriage, forms an annular trough in which located the toothed segment C, secured to the upper face of flange C. Inasmuch as in this instance the required range of rotary movement of the said frame is 90, the segment need be of sutticient length only to turn the said frame to that extent. The trough-like annular space in which the toothed segment is located is closed by the rim of the meter base B, as indicated more particularly in Fig. 4. The toothed segment 1s engaged by a pinion 5 located in a box formedin a boss on the side of the main frame A (see Figs. 1, 3, t, and mounted on the lower end of shaft E which extends vcrtically up through a supportin bearing in a boss on the rim of the. motor case B, and has on its protruding upper end an operat- 'ing hand wheel'E. By turning the hand wheel the shaft E and its pinion 5 will be rotated with the effect. of turning the se ment G and consequently the saw frame To lock the saw frame accurately in either of the two positions it is intended, by this rotary movement, to occupy, suitable stop devices can be employed, consisting in the present instance (see Figsl and 7) of a vertical stop pinF movable up and down in a holeein a portion of the motor base B overlying the annular rim of the saw frame in the top of which are two sockets e, e, exactly 90 apart, adapted, one or the other, to be engaged by the stop pin according to the position of the saw frame. The stop pin is operated by a lever F pivoted to a standard F on the base B. Its shorter arm engages the head of the stop pin and its longer arm forms a handle b depressing which the lever will be move in a direction to lift the stop pin far enough to release it from engagement with the saw frame, against the stress of a spring 6 which normally presses the lever in a direction to force the. stop pin downward.

Instead of making the vertical spindle D continuous, I prefer, as shown in Fig. 4, to divide it, into two parts, the opposed ends of which are connected by a universal joint D of some :1 )proved pattern, which unites the portion 0 the spindle that has its bearing in the saw frame, with the portion of the same that is an extension of the motor shaft. In this way I am enabled to compensate for slight changes in the position of the saw frame consequent upon its turning movement, which might otherwise cramp the action of the saw driving inst-rumentalities.

I believe this combination with the motor and motor carriage of a saw frame rotatable independently of the motor to shift the position of the saw, to be new with me.

The saw frame, it will be noted, is a gear box or case as well, and may be filled with oil or grease so that the gears, etc, operatin the saw may be run in a lubricant, thus reducing wear to a minimum. As herelnb fore stated, he travel of the motor carnage and the bridge over their respective tracks, can be effected in any known or suitable why. In the resent instance they are hand impelled, t rough the intermediary of suitable gearing connected to their truck wheels.
