EXPANSION-COMB FOR WARPING, BEAM|NG, AND OTHER MACHINES.
SPECIFICATION forming part of Letters Patent No. 34:3,801, dated Tune 15, 1886.
Application filed February 1, 1886. Serial No. 190,468. (No model.)
number of its parts, and to provide means of allowing the dirt and lint which ordinarily accumulates in a combbox to escape therefrom.
in the accompanying drawings, Figure 1 is an isometric view of my improved expansioncomb; Fig.2,a central Vertical longitudinal sec tion of the same; Fig. 3, a vertical crosssection of the same on the line or a: in Fig. 2; Fig. 4, a
central vertical longitudinal section through the comb-box and brackets of a modified form of the same, the modification relating to the means by which the comb is expanded, and the other parts being shown in elevation; Fig. 5, a vertical cross-section on the line y y in Fig. 4.
The comb hereinafter described is supported on the frame of the warping 0r beaming machine in any usual manner, and is adapted to be used with any warping or beaming machine in which an expansion-comb is used.
The ordinary expansion'comb consists of a series of dents arranged vertically between the coils of one or two pairs of springs, and pro-' jecting upward through a longitudinal slot in the upper part of the comb-box within which such springs and the lower parts of such dents are inclosed, and guide-rods which extend within said springs from end to end of the same on opposite sides of said dents to hold said springs and dents in their proper positions relative to each other, and a stop-rod which extends from end to end of the box through holes in the lower part of said dents to prevent said dentsbeing drawn out of said springs and comb-box. These guide-rods and the stop-rod frequently interfere with the expansion and contraction of the springs in certain parts thereof, and sometimes cause a permanent set or extension in the springs at some point, thus making the springs useless. The
comb-box as usually constructed is liable to grooved or hollowed out at B on its upper sur-' face nearly from end to end thereof, and slotted entirely through at B from the bottom of said groove B to the bottom of said bar, and almost from end to end of said groove. A spiral spring, 0, is laid in said groove and projects therefrom for more than half of its diameter. The spring 0 is prevented from rising out of the groove by a rod, E,which runs through said spring just out of contact therewith at the bottom of the same, and is secured at its ends by screws 6 c which pass through eyes 6 in the ends of said rod. The ends of the spring are bent into hooks c c, which engage loops h It, secured to the ends of metallic ribbonsH H, one at each end of the box, which ribbons arewound upon drums I I, supported horizontally in heads or brackets K K, secured to the ends of said bar or comb-box and turned by means of hand-wheels J J, secured to said drums, said drums being prevented from being accidentally turned by the friction thereon of said brackets, which are provided with horizontal slits k and with screws S S, which turn in said brackets vertically to contract said slits and to close the parts of said brackets above and below said slits upon said drums. The brackets are secured to the ends of the box or bar by screws.
The devices above named for expanding the spring are s'ubstan tiall y shown and described in Patent No. 383,399.
It will be seen that the coils of the springs being exposed above the top of the bar or box serve as dents, the spaces between said coils receiving the warp yarns just as the interdental spaces of an ordinary expansion-comb receive said yarns. The middle of the spring is prevented from moving longitudinally bya i wire, F, laid in notches f across said bar Ain the space between two coils of said spring,said wire being turned down over the sides of said bar, and the ends of said wire being provided with eyesf'f, into which screws are driven which enter the bar A.
In Figs. 4 and 5another means of expanding the spring is shown, which consists of screws in Fig. 4., as well as the means shown in Figs.
1 and 2, permit of expanding the spring from either end independently of the other end.
It is evidently impossible for lint and fiyings to accumulate on the bar A and between the coils of the spring to such an extent as to interfere with the expansion and contraction of said spring, because such lint and flyings will drop through the slot B.
I claim as my invention 1. The combination of astraight bar slotted through vertically nearly from end to end and provided in its upper surface with a longitudinal rounded groove openinginto said vertical slot, a spring laid in said groove, a rodplaced within said spring and extending through the same and having its ends secured to said bar within said groove beyond the ends of said slot, brackets secured to the ends'of said bar provided with horizontal slits, drums turning in said brackets, screws turning in said brackets to contract said slits to hold said drums from turning, ribbons or straps secured to said drums and to the ends of said spring, and means, substantially as described,of preventing the movement of the middle of said spring, as and for the purpose specified.
2. The combination of a straight bar slotted through vertically nearly from end to end and provided in its upper surface with a longitudinal rounded groove opening into said vertical slot, a spring laid in said groove, a rod placed within said spring and extending through the same and having its ends secured to said bar within said groove beyond the ends of said slot, brackets secured to the ends of said bar provided with horizontal slits, drums turning in said brackets, screws turning in said brackets to contract said slits to hold said drums from turning, ribbons or straps secured to said drums and to the ends of said spring, and a wire or rod placed between the middle coils of said spring and secured to said bar, as and for the purpose specified.
In witness whereof I have hereunto subscribed my name this 27th day of January, A.
