IMPROVEMENT lN BOBBlN-SUPPORTERS FOR YARN-SPOOLING MACHINES.

Specification forming part of Letters Patent No. 172,548, dated January 25, 1876; application filed December 9, 187 5.

To all whom it may concern Be it known that I, JOSEPH B. BANOROFT, of Hopedale, of the county of Worcester and State of Massachusetts, have made a new and useful Invention having reference to Bobbin- Supporters of Machines for Spooling Yarn; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- I Figure 1 is atop view, Fig. 2 an end elevation, Fig. 3 a transverse section, and Fig. 4 a front view, of a series of bobbin-supporters provided with my invention. separate side view of one of the gravitating lip carrying-arms of one of the said supporters.

The main purpose of my invention is to enable a series of the bobbiirsupporters of a spoofing-machine to be all adjusted at once, or to be separately adjusted, to proper inclinations, v as occasion may require; also, to have the bobbin trough or rest fastened to the carrying-arm by a clamp-screw separate from that by which the said arm is held to its support-piece, it having been heretofore custom-. ary to connect the arm, the rest, and the sup-.

porter by a single clamp-screw going through all of them. Loosing the nut of said screwin order to adjust the rest, loosened the connection of the carrying arm and the support-piece, and rendered the said arm liable to fall out of place; but with my improvement such cannot occur.

My invention or improvement in a spoolingmachine consists in the combination of a cylindrical sustaining-rod, its standards or supports, and clamp-screws, with a series of bobbin-supporters applied to said rod, and provided with clamp-screws, all beingas hereinafter specified, and as represented.

My invention further consists in such bobbin-supporter not only having the carryingarm or goose -'neck of its gravitating lips provided with a collar, clamp-screw, and ear, but having the bobbin-rest provided with a separate ear, and secured to such goose-neck car by a separate clamp-screw, all being as described and shown.

In the drawings, A A are two bobbin-supporters, both being sustained by a cylindrical Fig. 5 is a' rod, B. The foot or lower part of the gravitating lips, carrying arm a of each of said supporters, is a cylindrical ring or collar, b, through which the rod B passes, there being to such collar a clamp-screw, c, which is screwed laterally into. it and against the rod. Furthermore, there projects from the collar b an ear, d, to which another ear, 6, extending down from the bobbin-rest f, is fastened by another clamp-screw, g, which goes throughthe ear d, and screws into the ear 0, one of said ears being arranged alongside of the other, as shown. The shank of the'screw, g is'of necessity cylindrical; consequently the inclination of the bobbin-rest f may be varied, and the rest be clamped in posit-ion without varying that of the arm .or goose-neck a. relatively to the shaft B. The sustaining-rod B is so supported by and in standards 0 O as to enable it to be revolved in them, it being held to each by-a clamp screw, h, screwed into the standard and against the rod. The pendulous' lips are represented at k k as suspended from the goose-neck or carrying-arm by means of a bearing-block of wood inserted in a pocket in the head of the said neck.

From the above it will be seen that not only can eachof the bobbin-supporters A A be adjusted on its rod independently of and at its proper distance from the other, butall can be moved at onceby turning the rod in its sup' ports also, that the bobbin-rest of each supporter A can also -be removed from the car 01 without disturbing the connection of the gooseneck with its support-piece, all of which are matters of much importance in a 'spoolingmachine, in order to effect the proper inclination of the bobbins.

The bobbin-supporter shown in the drawin gs is very like that represented in the United States Patent, No. 159,053, to Asel M. Wade, in which the bobbin-rest and the goose-neck are both applied to one sustaining-arm, and connected thereto by a single screw and nut. To adjust either part their connection has to be loosened, whereby an attempt to adjust the bobbin-rest would disturb the adjustment of the goose-neck, and vice versa. In my bobbinsupporter the bobbin-rest, by being sustained by means independent and separate from such as are used to support the goose neck, can be removed, as described, without disturbing the screw 6 or means by which the part a is held to theshaft B. i.

I claim as my invention in the bobbin-supporter of a spoofing-machine as follows, viz:

1. The combination of the rotary cylindrical sustaining rod B, its standards G G, and clamp screw or screws h, with a series of bobbin-supporters, A, applied to such rod in the manner herein described, and provided with clamp-screws 0 c to operate against it, all substantially as specified.

2. Each bobbin-supporter having its gooseneck or lips, carrying arm (1, provided with a collar, b, clamp-screw c, and ear d, in combination with the bobbin-rest f, provided with an ear, 0, and a clamp-screw, 9, whereby the ear 0 is fastened to the ear (I, all being essentially as set forth.

JOSEPH B. BANOROFT.
