SPEEDER-FLIER.

SPECIFICATION forming part of Letters Patent No. 350,782, dated October 12,1886.

Application filed April 4, 1884.

To [LZZ whom it may concern:

Be it known that I, JOHX A. V. SMITH, of .lIa'nchester, county of Hillsborough, State of New Hampshire, have invented an Improve ment in Speeder-Fliers,of which the following description,in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Heretofore in that class of Speeder-fliers having their pressers connected with short shafts placed in bearings outside the pressers, and provided with a pin to be engaged by a notched sleeve or hub connected with a spiral spring, very considerable difiiculty has been experiencedin connecting the springwith the sleeve or hub and with the foot-piece at the lower end of the spring. In such fliers the spring has been brazed or soldered directly upon the end of the sleeve or hub, and upon the fiat side of the footpiece, as illustrated in Figure 5 of the drawings herein, andso attached the spring under strain is very apt to be broken away from the hub and foot-piece.

My invention is designed to overcome these difficulties; and to this end it consists in means for connecting and adjusting the spring of a presser, substantially as hereinafter pdllllfl'b larly set forth and claimed.

Fig. 1 represents a speeder-flicr embodying my present improvements; Fig. 2, an enlarged partial side elevation of Fig. 1, but partially broken out; Fig. 3, a section of Fig. 2 in the dotted line Ll m; Fig. 4, a modified form of hub; and Fig. 5 represents a hub, foot-piece, and connected spring as heretofore constructed and in use.

Referring first to Fig. 5, it will be seen that the wire at the upper and lower end of the spring a is cut to form a fiat surface. One of these flat surfaces is placed against the end of the hub b and the other against the upper side of the foot-piece c, in which condition the said parts are soldered together, leaving but a por tion of each end coil held to the hub and footpiece, and held as shown they are very liable to be broken off.

In accordance with my invention,the sleeve or hub (Z and foot e, Figs. 1, 2, and 3, are each shaped to enable at least one entire coil of the spring f to be engaged and held securely in place thereby. In Figs. 1 and 2 the hub d is Serial No. 126,657. (Yo model.)

chambered, as at d, (see Fig. 2,) to receive the end of the wire spring f, and so, also, the foot e is chambered, as shown at e, to receive the lower end of the said spring, and the first coil of each of said ends is then soldered thereon, the solder being shown at d" and c in black. In this manner each end coil is held firmly all about, and the end coil cannot be knocked off or broken from its connection with the hub and foot by a blow against the spri-ng,asis frequently the case with the attachment of the spring to the foot and hub, as is shown in Fig.5.

As a modification of my invention, the hub may be reduced externally and prolonged, as in Fig. 4, to enable the spring to surround it, rather than, as in Fig. 2, to let the hub surround the spring, the hub shown in Fig. 4 being the 'converse in construction but the equivalent in operation of the hub shown in Fig. 2. The strength exerted by the spring on the presser it may be adjusted by causing the pin it ot the rod 7t'-,to which the presser is attached, to engage one or the other of the longitudinal notches in the upper end of the hub d, or by lifting the toot-piece. c, which I have made of circular t'orm and provided at opposite sides with projections 2, one of which is shown at Fig. 2, the other being just like and opposite to it, (see section, Fig. 3,) the said projections entering notches made at the upper side of the bearing-car h. The upper bearing for the rod it is marked h The legs 22. and heads a n of the flier are all as common. In the old form (represented in Fig. 5) the l'ootpiece 0 takes but one bearing-that against the arm of the flier-and the strain exerted upon the spring by the movement of the presser acts to force the spring upward, and also against the rod within it, with which the presser is connected, such strain,besides throwing the spring out of perpendicular position, causing friction between it and the rod, which prevents the free action of the spring when in use,which results in the making of uneven roving or yarn. In

this my invention the footpiece having the spring connected with it, as described, and also being provided with two projections which enter recesses in the bearing h, is prevented from tipping or twisting out of shape, so as to bear against the rod, and consequently the tension and action of the spring upon the presser are one end of the wire spring, combined with the 1-5 said spring and a foot provided with a downward projection, 2, to enter a corresponding recess in the bearing If, the said foot being made as described, to sustain one coil of the spring, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two sub- 1 scribing witnesses.
