To all whom it may concern v Be it known that I, OLIVER PEARL, of Lawrencc, in' the co'untyof Essex and State of lilassachus'ctts, have made a certain new and useful invention"having reference to Machincry for Spinning, of which the following is-a specilicationi 7 My invention relates, first, to certain improvcn'ients in-the construction of bobbins having, frictional or adhesive bearings uniting ilicnr to' thespindle and carried by it, the objeetot' thispart of m y invention being to make a-very'lighl'. bobbin, and strengthen itsvarious partsj'so that it will-imt be easily crushed or broken; secomh'to an improved construction and combination of both the bobbin and ringspindle, so that they can be successfully used with greater advantages of length of traverse,"

speed, and steadiness of rotation than heretofore attained, and at the same time be much lighter, the object of this part of my invention being to greatly diminish the amountot' power required to drive the spindle at an v given speed, and increase its eflicicnt operation at the same time. 5

Figure 1 is a vertical section of a ring-spin,

dle and bobbin made according .to my invention. Fig. 2 is avertical section of a ringspindle and its bobbin in common use prior to my invention. p

Heretofore ithas been customary to construct bobbins, having adhesive bearings which secure them rigidly to the spindle with which they rotate, heavy and solid, as shown in Fig. 2, because, unlike bobbins which 1-0 a bore extending through them with an adhcsive' frictional bush or hearing at each or either end to support them upon the spindle.

By an adhesive or frictional bush or bearing 1 mean oneconstructed to support the bobbin in a fixed position on. the spindle, while it rotates and carries the bobbin with it, in contradistinction to a bush or hearing on which the bobbin revolves on the spindle freely. WVhen constructed with the bore hushed only att-he ends, as described, the bobbin, if made light and thin, is liable to become crushed 'orbroken on account of want of strength in the middle. It has also been customary to con-' struct ringspindles, as shown in Fig. 2, extending substantially to the top of the bobbin, and ot' a certain length above the bolster, which supports them in the upper rail of the spinning--i'ra|ne, in order to give sufficient length ot'traversc in spinning luasmueh as the spindle above the bolster 1) must be thick enough to prevent its springing, the requisite length and thickness of this part, commonly called the blade of the spindle, give it a certain weight, in proportion to its length, corresponding with the traverse; but, as, in order to properlybalance the spindle, it \"as requisite that the weight of its blade above the holstcrshould be in proportion to a very much greater weight of the spindle and whirl below the bolster, to insure its steadiness of .rotation, it is obvious that, with the blade extending to the top of the bobbin, as described, the weight of the entire spindle could not be successful] y reduced below a certain standard.

ordinary cylindrical form, having attached to it the whirl C, and supported by I the bolster l) in the upper rail of the spinning-frame, and constructed to rest and revolve at its lower end in a step in the bottom rail. of the frame. 011 the spindle, in the position. in which it is intended to operate, is reprcmnted a bobbin of my i'nprovcd construction. This bobbin is made witha thin and light shell or barrel of wood, and has a lower adhesive or frictional bearing, k, and a middle one, i, and is also hushed at the upper end by a plug, re'cnforcc, or bushing, 1., and the bearings hi and bushing 1 are united to and combined with the shell of the bobbin, 'and strengthen itin all directions from bci n g broken. 'lheadhesivc or frictional bearin gs k a are made to sustain the bobbin on the spindle in one position with rc- In Fig, lthc ring-spindle is shown of the spindle to 'lation to the latter, and so as to enable the carry the bobbin with 'it in its rotation.

In Fig. 2, Adenotes an ordinary ring-spindle, and B a bobbin for it. o

In Fig. 1 my improved ring-spindle, instead of extending snbstantially tofthe upper end of the bobbin, as heretofore, is only made long enough above the upper bolster D to enable the adhesive'bearing i at the center of the bobbin to hold the latter firmly upon it, as shown. I am thus enabled to remove a large portion of the upper part of the blade of the spindle above the bolster D, and the tube of the bobbin projecting beyond the shortened blade of the spindle, resting, by its adhesive central bearing, upon the latter,-and, being both light and rigid, retainsits length and the position which it had before the. spindle-bladewas shortened, while the traverse of the spin- .1ing-frame and the length of the bobbin remain as before;

.By thus dispensing with the length and weight at the top of the spindle above the bolster, while the length of bobbin and trav: erse of the frame remain as before, relatively, I am enabled to lighten'the lower part of the. spindle and whirl below the bolster 1) many times the weight taken from its blade above, without destroying the proper balance of the spindle and its consequent steadiness of -rotation, and by these means I aecomplisb'theultint-ate efl'ect, which is thepurpose of this improvement, of enabling the spindle to be run steadily at high speed with much less power thab heretofore, thus diminishing the expense and increasing theprodnction atthe same time.

Inthc bobbin, Fig. 1, the chambers g h intervene between -the bearings kl i-and the bearing i and bushing 1 within the bobbin, and the bobbin is made of a light and thin'cylinder supported at the middle and ends, and

the cylinder canthus be made light and thin and cannot be readily'broken either at the middle or ends; and the bushing l at th'eupr my bobbin.

per end of the bobbin, being at the point where itself made lighter by-a central borc, m, as

lightness at this point, so far above the bolster D, is important.

The central adhesive bearing 5, besides supporting the bobbin on the spindle rigidly, as described, serves to strengthen the bobbin at the point on the solidity'of which the pro jccting part of the bobbin (that performs the functions of theportion of the spindle-blade removed) depends for its efficiency. I therefore combine great lightness and strength in What I .claim as new, and-my invention, 1s

1 The described ring spindle, havingv its blade from the bolster I) upward shorter than the bobbin and combined with the bobbin, constructed substantially as described, by means of the adhesive bearings, as and for the purpose set. forth. i

2. The combination of the" bobbin, the intermediate adhesive bearing 2', and the blade of the spindle made shorter than the bobbin from the bolster D'upward, substantially as described.

'3. The described bobbin, provided with the central adhesive bcaring'i, the chambers 'g h, and'the adhesive tbotrbearing k, substantially as described. V

4. The described bobbin, provided with the central adhesive bearing i, the two chambers g h, and tho'nppcr and lower end bushingsor heads, substantially as described.
