SPECIFICATION forming part of Letters Patent N 0. 447,334, dated March 3, 1891.

Application filed November 28, 1890. Serial No. 372,812- (No model.)

To all whom it may concern.-

Be it known that I, SINAi LETIECQ, of the city and county of WVorcester, and State of Massachusetts, have invented certain new and useful Improvements in Power-Shipping I necessary to illustrate my invention; Fig. 2

is a central vertical longitudinal section thereof independent of the shipper and main supporting-frame; and Fig. 3 is a modification 1n the construction hereinafter more fully described.

l\ly invention relates more particularly to shipping mechanism for drilling-machines; but I do not limit myself thereto, as it is equally applicable to other machines having back-gearing and in which it is desirable to change the speed from a low to a high speed, or vice versa. k

Said invention consists in certain improvements in the construction and arrangement of the various parts which constitute said shipping mechanism, as will be hereinafter more fully set forth.

In order that others may better understand the nature and purpose of my said improvements, I will now proceed to describe the same more in detail.

In the drawings, the parts marked A represent the upper main supporting-frame of the-machine, which in practice is provided with suitable bearings, as usual, for the shaft B to turn in, one of said bearings 0 being shown in Fig. 1. To said main frame is secured the frame A, which supports the intermediate gears and shipping device, said frame A also having a bearing A for. the shaft B to turn in. Upon said shaft B are mounted the cone-pulley D, sleeve E, gear F, and collar G, which are constructed and arranged as follows: The cone-pulley D is fitted to turn loose on shaft B, is provided with an internal collar D, secured to the shaft for holding said pulley from inward longitudinal motion, and with atoothed hub D adapted to engage with the sleeve E. Said sleeve E is splined to shaft B and fitted to slide longitudinally, being also provided with a toothed end next to the cone-pulley, adapted to engage with the aforesaid toothed hub on the pulley to form a clutch between the two. The gear F is fitted to turn loose on shaft B and to slide longitudinally between the bearing A and collar G. It is also provided with a toothed hub F next to said collar, adapted to engage with the latter, which in turn is correspondingly toothed and secured rigidly on shaft B. A sleeve II, having a pinion H thereon, is fitted to turn as well as slide longitudinally on the sleeve E, previously alluded to, and is provided with a toothed end H next to the cone-pulley, (similar to said sleeve E,) adapted to engage with the toothed hub D on said cone-pulley, said hub D being of sufficient size to engage with the toothed ends of both the sleeves E and H, as is indicated in Fig. 2 of the drawings.

Upon the ends of the short horizontal shaft I, which turns in frame A, are secured the pinion J and gear K. Pinion J engages with the loose gear F on shaft B and gear K with the loose'pinion H'on sleeveI-I, in turn fitted over sleeve E, as previously stated. An intermediate gear-connection is thus made between the gear F, which engages with the fixed clutch-collar G on shaft B, and the clutchsleeve II, which engages with the cone-pulley. The sleeve E and gear F are connected by means of a horizontal rod L, fitted to slide in frame A, and forks L L, which are secured to the ends thereof and fit in annular grooves a a in said sleeve E and the hub of gear F. A similar slide-rod M on frame A, having a fork M on one endfengages with the sleeve H, upon which is mounted the pinion H, said fork fitting in an annular groove bin the end of said sleeve. To the opposite end of rod M from its fork is pivoted the upperend of the shipper N, which is also pivoted to rod L at 95 the left of its bearing in frame A and to the frame A between said pivots.

By the foregoing construction and arrangement it is obvious that when the lower end of the shipper N is moved toward the left the gear F is moved with it and clutched to the fixed collar G on shaft 13, while the sleeve ll. and its pinion II are moved to the right and clutched to the hub of the cone-pulley D. At the same time sleeve E, being moved to the left with gear F, is unclutched from said conepulley, thereby communicating the power from the shaft through the train of intermediate gears to the pulley, and at the same time unshipping said pulley from direct connection with the shaft, consequently obtaininga low speed through said intermediate gearing.

To communicate the speed of shaft B di root to the cone-pulley, and thus obtain the higher rate of speed, the lower end of the shipper is moved toward the right, said operation causing the gear F to be disconnected from the fixed clutch-collar G, the sleeve II disconnected from the cone-pulley, and the sleeve [E connected with said cone-pulley, as will readily be seen by reference to Fig. 1 of the drawings.

In said drawings the various parts are shown in the positions that they occupy when the cone-pulley is connected direct with the shaft 13 through the sleeve E and disconnected from the back-gearing.

In Fig. 3 a similar construction to that hereinbefore described is shown, the clutchcollar G being secured to shaft B and sleeves E and II fitted to slide and to engage with the hub of the cone-pulley, as in the former instance, the difference being principally in the arrangement of said sleeves, the sleeve E being in this instance arranged on the shaft within the cone-pulley and adapted to engage with the inner end of its hub instead of outside of said cone-pulley and the sleeve II, on which is mounted the pinion H, being arranged on the shaft instead of over the sleeve E, connection being made between the two sleeves by a horizontal forked rod M fitted to slide in the cone-pulley instead of connecting the forked rod L with the sleeve E, as in the former instance, and to accommodate this construction both ends of the cone-pulley hub D are toothed, as is shown in said Fig. 3. Otherwise the construction and arrangement are substantially the same as in the first two figures described, and the principle of operation is substantially the same in both cases, as will readily be seen.

I am aware that other mechanisms of a si milar nature, but differing in construction from my invention, have been patented, and I therefore limit my said invention to the specific construction herein set forth, and pointed out in my claims.
