IMPROVEMENT IN SPINNING-FRAMES.

Specification forming part of Lettus Patent No. 152,881, dated July '7, 1374; application filed February 10, 1572.

To all whom it may concern Be it known that I, Josnrrr Mason STONE, of North Andover, in the county of Essex and State of Massachusetts, have invented certain Improvements in Spinning-Machincs, of which the following is a specification:

M y invention relates to the construction of that part of a spinning-machine which sup ports the spindles, and receives the bearings in which they revolve, and to other parts working in the same connection, by which im- 'n'ovements the spindles are more accurately held in position, and the parts are more conveniently and cheaply made. One of my im provements consists of a new mode of fastening the spindle-step, as will be described. Another improvement consists in splitting the partitions between the sockets that receive the SDlIIdlCSFGPS, or the bolsters in the spindlerails, or the rings in the copping-rail, so that, by forcing in the steps or parts to be held, moderately, they will be held in place by the elasticity of the socket, or by contracting it by a screw, as will be described. Another improvement consists in the formation in the lower rail of an oil pan or reservoir, which receives the waste oil from the steps of the spindles, and from which also I propose to oil the steps, if desired. Another improvement consists in forming the sockets or sleeves for the guide-rods, which carry the copping-rail, in one piece with the spindle-rails, as will be described; and alsoin. a new method of form ing the bearing-surfaces in said sockets, in which the guide-rods work. Another improvement consists in the use of thin sliding panels or doors to close the space between the spindlerails in front of the spindles, which doors slide in grooves in the spindle-rails, as will be de scribed.

In the drawing, Figure 1 is a front elevation of the spindle-frame and parts connected therewith, with a part of the lower rail in longitudinal section. Fig. 2 is a rear elevation of the same. Fig. 3 is a horizontal section above the lower rail. Fig. 4 is a crosssection through the center of a spindle, with spindle-bcarin gs ot' the usual form. Fig. 5 is a cross-section through the center of one of the guide-rods ot the copping-rail. Fig. 6 is a top view of a portion of the upper spindle rail, and Fig. 7 is a top view of a portion of the copping-rail of the preceding figures. Fig. 5: is an enlarged vertical section of the spindlefralne fitted with my improved ring, and bolster, and step. Fig. 9 is an enlarged view of Fig. 5, to show more clearly its construction. Figs. 10 and 11 are detached views of a port-ion of the copping-rail fitted with my improved rings. Figs. 12 and 13 are detached views of a portion of the lower spindlerail fitted with my improved steps.

A is the upper spindle-rail, and B is the lower rail, which are both made in one piece, being connected at the back side by the small cross-bars a, between each two spindles, or at such intervals as may be desired, and the sockets or sleeves I), which receive the guide rods 0, which carry the eopping-rail 1'), and the feet 0, by which the rails are attached to the end frame of the machine. For distinetion in this description, I call this self-contained part of the machine the spindle-frame. The bearings and steps of the spindles may be made and secured to the' rails in any usual way, or modified, as will be described. E E, &c., arethe spindles; and F F, 850., are the whirls by which they are driven, as usual. The spindles are shown as working with the ring and traveler, so called but the improvements described may be used in connection with spindles working either with or without fliers, with the same advantages. F is the bolster or upper bearing of the spindle, which may be fitted into the upper railAin the usual way, or as is shown in Fig.6. It is formed with a part, g, which extends below the upper rail nearly to the whirl F, and serves as a stop to prevent the spindle from being raised when the bobbin or cop is drawn oft. By this construction, the necessity of making the spindle with an enlarged part, so as to form a shoulder beneath the bolster, to pre' vent the spindle from rising, as is usual, is avoided, and the spindles can be made lighter, with equal etliciency in operation. The part also, by its contiguity to the whirl, takes the lateral strain of the driving-bandf, without tending to bend the spindle, and also gives a very large wearing-surface to the bearing. The drivingbands lead from the whirls to the main drum through the openings between the bars a, as is shown by the dotted lines f in Fig. 4. Each of the bosses ll of the lower rail B, which receive the steps II, may be sawed through lengthwise of the rail at h, to the bottom of the socket, so that the socket will yield slightly when the step H is forced into it, and thereby hold the step with sufficient firmness without any other fastening, and, at the same time, without straining the rail out of shape, and saving the cost of the set-screws usually employed for securing the steps. The bolsters F and the rings M may also be secured in a similar manner to the rails A and I), respectively, as is seen more particularly in Figs. 6 and 7, in which a slit, 4', is out between alternate sockets, as shown, or slits may be made between several sockets in successiomleaving a sufficient number of the spaces between the sockets solid to preserve the strength of the rail. If a further security is required, screws may be put in between the sockets through the slits, as shown, which will further gripe the socket upon the bolsters or rings, as the case may be, if desired.

The ring M, as shown in Fig. 8, is of a T form, in cross-section, and is set into a shouldered recess in the copping-rail, as is shown.

In Figs. 8 and 12 is shown my improved spindle-step. It is made with a cylindrical shell or lasing, Q, provided with a shank at the lower end, to set in the lower spindle-rail, which shank, in its axis, receives a small screw, m, which passes up through a hole in the rail from beneath, as is shown, and serves to hold the shank into its socket in the rail, and when the screw is removed it enables the step to be driven out by means of a drift which is in serted through the hole. B is a piece of composition, or other suitable metal, of the form shown in section, which forms the bearing for the spindle. At its ends the piece R is made to fit the cylindrical cavity in the shell Q, but the intermediate portion of its surface is removed, which leaves a cavity or space, S, between its surface and the interior of the shell to form a chamber for oil. This space is connected with the bearing of the spindle by holes, as shown in Fi 8, or by cutting away a portion of one side, as is shown at the right hand in Fig. 12. The holes or spaces open toward the front of the machine, so that the side that sustains the draft of the band may be entire. By this construction the entire surface of the piece It, both inside and out, can be finished in the lathe.

The lower rail B is made with a recess or oil'pan, I, as shown, which catches the oil from the steps ofthe spindles; and I also contemplate oiling the foot of each spindle from this, by so forming the steps If that the oil will flow into the bcarin gs from the oil-pan I, through the slit 71., or a hole formed for the purpose, in an obvious manner. The guiderods (J are fitted to slide accurately through the sleeves I) of the spindle-frame, and are attached to the copping-rail D, and to the mechanism for raising and lowering the same, in any usual way employed where a coppingrail is used; but in mules and jacks the copping-rail and its adjuncts would be omitted. The method in which I propose to make the bearings for the guide-rods in the sleeves b is shown in Figs. 5 and 9, in which the hole through the sleeve is made somewhat larger than the guide-rod, and the space between them is filled with a lining of soft metal, such, for instance, as an alloy of lead or tin, which is cast into the sleeves around the guide-rod, after it has been accurately placed in position, making a very cheap and excellent bearin I propose to place the guide-rods in position in the sleeves by means of the templet or frame, by which the boring of the sockets of the several spindle-bearin gs is directed. K K are sliding doors or panels, which slide in grooves in the upper and lower spindle-rails, as is shown in Figs. 3, 4, and 5, to close the space between the rails in front of the spindles. The doors are made in lengths of about four feet, more or less, and are alternately placed in and out, as is shown, so as to slide past each other, by which arrangement all the spindles are accessible. I propose to make the panels of Russia sheetiron.

By this mode of construction, the spindleframe, with the parts attached thereto, can be entirely completed before the spindle-frame is placed in the machine, and the holes for the bearings in the several rails :an all be bored at the same time, by means of a suitable templet, at one operation, so that all the holes will be truly concentric, and the relation between the upper and lower bearings of the spindles will be accurately preserved, even if the spindle-frame changes its form or position and the economy and convenience of fitting the work to the spindle-frame while detached from the machine are very important.

\Vhat I claim is- 1. The screw m, in combination with the shank of the spindle-step, for the purpose of confining the same in the spindle-rail, substantiall y as described.

2. The split partitions between the sockets, for holding a spindle-step, bearing bolster, or ring, substantially as described.

3. The oil-pan I, in combination with the lower spindle-rail, substantially as described.

4. The sockets or sleeves I), in combination with the spindle-rails, and connecting the same, substantially as described.

5. The sliding panels or doors, in combina tion with the spindle "ails, substantially as described.
