HAM, "RUSTEE AND' SAID TRUSTEE ASSIGNSTO SAIDl MAYOR AND GEORGE- OHATTERTON, OF SAME PLACE.

To all whom it may concern Beit known that l, THoMAs MAYOR, of the city and county of Providence, in the State of Rhode Island, have invented a certain newr and useful Improvement in Speeders for Spinning and Twisting Roving, and .I do hereby declare that the following specification, taken in connection with the drawings making a part ofthe same, is a full, clear, and exact description thereof. l v f Figure 1 is an end view of a portion of the machine.

Figure 2 is a view oi one oi' the spindles and its bolster.

Figures 3, 4, and 5, are views of the peculiar bob-v bin employed. l

Figures U, T, and 8, are sectional views of' the iiier. The iirst part of my invention relates to a new construction of the spindle and means of driving and Incidental to these improvements, other important advantages.l result in reference to the arrangement of the machine, which will be hereafter stated.

A, iig. 1, represents -a portion of the frame.v

a a are feeding-rollers, delivering the roving b to the -ilier B.

The spindle is shown at C, and upon a larger scale at tig. 2.,

It is stepped at c, g. 1, in a foot-rest, D, project- .ing from the lifting-rail E, whichv rail, it is to be supposed, is made to traverse by anysuitable mechanism in some one of the ways in use.

The spindle is peculiar in its construction, in this: its upper end is furnished with a square, F, and ange, d, in order to furnish a means for driving the bobbin, by the application of the driving-power to its upper instead oi' to its lower end.A It is not essential that this precise form should be given to the end ofthe spindle, and any -mechanical construction. which will eifect the driving of the bobbin at this point, will enable the invention, which results ii'oin such application of the driving-power, to be employed.

The spindle is mounted in a long stationary bolster 'or-tube, G, which may be cast in one piecewith the yoke H, which latter is iirrnly bolted, as seen in iig. 1,

to a girt, I, running from end to end of the frame.

The bobbin J is of the usual length, but its axis i's bored ont, so 'as to iit the bolster, but its head is closed, all but a square opening, into which the squared end of the spindle fits.

`head will rest' upon the ilange d, and be supported by' it, ,while its lower end, (the bobbin being longer than' the length .of the spindle above the bolstcr,) will take almost perfect steadiness of movement to the bobbin,

notwithstanding that it is made to traverse to the extent of its length," past the end of the flier-arm, by the movement of the lifting-rail, there being, at all times, a bearing for it at bothcf its ends.

Asan' incident, too, of this manner of constructing the bobbin, nearly all dust and particles of cotton are excluded' from entering the holster, in conscilu'cnoe of" the protection which the bobbin affords.

The spindle is driven by the bevel-gear K, which engages with the bevel-gear k', connected with the spindle by means of the long feather e, ittcd 'to slide through the hub 7o', as the spindle is lifted and lowered by thetraverse-rail E.

This arrangement for giving motion to the spindle, enables the driving-gear K to be mounted upon a shaft, f, fig. 1, extending from end to end of the frame, and elevated above the foot-bearing of the spindles, and in front of such spindles.'

It will be observed that the yoke H, to which the long bolster G is attached, is formed, at its lower extremity, into a bearing for the spindle, between the long bolster G and the step-rail D. (See iig. 1.)

This intermediate bearingaffords arest for the bevelgear K', and' is in place of the rail sometimes used.

The gear K is, by this arra11gement,enabled to be placed with its bevel-face downwards, and the fellow .bevel-gear K can thereby be located nearer the iioor than would be practicable were a rail employed. Consequently, the height of the machine, by this change in the customary location and arrangement of the driving-gear, is materially reduced, and the usual raisedlplatform, for the operator to stand upon to reach the bobbin, is dispensed with.

Moreover, this arrangement of the driving-gear greatly simplifies the structure of the machine.

It is easily accessible, not readily deranged, and isv peculiarly adapted to a machine employing a double row of spindles.

Another improvement relates to the construction oi' the iiier. l y The neck L of the iiier is constructed with the usual axial hole, and also with two lateral oriices,one above Ythe other, in opposite sides ofthe neck, leading into the axial hole, as described' in the Letters Patent granted to.me, rMarch 21, 1865.

` The additionalimprovement consists in connecting the axial hole, through the neck of the lier, with the lower one of the two orifices, through the side of the neck, by a slit,- g. v v

' The object of this isvnot only to make it more convenient for the operator to piece up broken ends either from above or from below, but also to furnish a device for breaking the yarn, in case the roving has not been properly conducted to the ier, by being entered into the axial hole, then led through the uppermost of the two lateral orifices, and thenwound partiallya-round the outside of the neck, and entered into the lower orifice, as` it should be, in order to insure its being properly twisted. 'So long as the roving is conducted to the flier in this path, the slit g will not produce any effec-t, but if, by neglect, the roving has not been put through both holes, as described, it will work into the slit, and` be instantly broken. A

I have found it advisable to surround the neck of the iiier, at the upper bearing, with a collar or bushing, h, which may be of' cast-iron, mineral, glass, or other suitable material, and which is made removable from the flier, so that it can readily be replaced when it has become worn.

lhe Vmachine hereinbefore described can be constructed, without radical alteration, to work either' as a Speeder or as a flier-flame, and speedcrs of the old forms in use, can be readily changed, so as. to employ the means of driving the bobbin, and the arrangement to insure its steadines's of movement above de-` scribed.

What I claim as my invention, and desire to secure by Letters Patent, is 1. The method,substantially as herein specified, of driving andlsteadying a bobbin, by combining the bob# bin J with the' diiving-spindle O and the stationary 4bolster G, so that While the. bobbin is driven by the fonner, it shall, in all positions, be steadied by the latter, as-herein set forth andfdescxibed.

2, In'combination with thesneck L of the flier, where such neck is constructed with two lateral orifices, for the passage of the roving, as described, the employment of a slit, g, connecting the axial hole in eral orccs, as herein described, for the purpose of breaking the yarn, whenever the roving has not been properly lcd to lche flier.

3. The arrangement, with reference to the long bolster G and step-rail D, of an intermediate spindleibearing, attached to the same yoke or frame which supportsv the bolster G for the purpose of furnishing a rest for. the bevel driving-gear K', and, also, the arrangement of' the fellow bevelrear K with such driving-gear K' and intermediate bearing, substantially as shown, whereby the height of the machine and the length of' the spindle are enabled to be` reduced, as

herein set forth.
