Claims.
This invention relates to loom shuttles, and it relates more particularly to improved means, in such shuttles, for holding the bobbin against longitudinal displacement within the shuttle body. 5
The devices at present in common use for preventing undesired movement of the bobbin within the shuttle body mostly comprise metallic members of various forms and, by reason of the failure of the weavers to observe the proper care during the changing of the bobbins, the flange portions of the bobbins quickly become damaged and the bobbins must then be discarded notwithstanding the main portions thereof are still in good working condition.
The principal object of the present invention is to provide, in a loom shuttle, simple, eiiicient and inexpensive means for holding the bobbin against longitudinal movement after the bobbin has been placed in position in the shuttle.
A further object of the inevntion is to provide a device of the character aforesaid which will permit the ready placing and removal of the bobbin with respect to the shuttle, without likelihood of damage to any of the parts.
A further object of the invention is to provide a device of the character aforesaid which will readily accommodate itself to slight variations in size and location of the bobbin, and which will serve to reduce wear on the parts to a minimum. l
The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:
Figure 1 is a vertical central section of a loom shuttle provided with a bobbin holding device embodying the main features of the present invention, the spindle and bobbin being shown in the raised or dofng position;
Fig. 2 is a top or plan view thereof, but with the spindle and bobbin shown in the lowered or operative position;
Fig. 3 is a transverse sectional view taken approximately on the line 3-3 of Fig. 2;
Fig. 4 is a side elevational view of the bobbin holding member detached from the shuttle; and Fig. 5 is a front elevation thereof.
It should, of course, be understood that the description and drawing herein are illustrative merely, and that various changes and modifications may be made in the structure disclosed without departing from the spirit of the invention.
Referring to the drawing, I0 is a shuttle body of a usual type, provided with a spindle opening II, and having a spindle I2, the heel I3 of which is pivotally supported by a bolt or pin I4. The heel I3 of the spindle I2 is provided with the usual flat side I5, and projection i6, adapted to be engaged by one end of a plate spring I1, which serves to retain the spindle I2 either in its normal axial position within the shuttle I0, or in its upturned or doiiing position as shown in Fig.
1 of the drawing. The plate spring I1 is secured in place in the shuttle IU by means of the usual bolt or screw L8.
The bobbin I9 is adapted to be positioned upon, or removed from, the spindle I2 in the usual manner. The bobbin I9 is usually formed of a relatively light material, such as paper or the like, and preferably is provided at its rear end with a thin metal ferrule 20 terminating in a flange 2l.
The device of the present invention, for preventing longitudinal movement of the bobbin on the spindle when these parts are in their operative positions, comprises a U-shaped metallic plate 30 having on one face thereof a layer 3l, of rubber or similar resilient material. The rubber facing 3| may be vulcanized directly to the metallic plate member 30, or it may be secured thereto by suitable adhesive. Preferably the device is made by first securing the rubber facing 3l to the sheet stock from which the device is made, so that, when the same is punched from the stock, the rubber facing 3I is simultaneously punched to the same outline.
The device is mounted in the shuttle body in vertical grooves 32 out in the side walls thereof at the proper location. The lower end of the device is provided with a forwardly extending lug 33 formed by bending the metal around at a right angle, as indicated in Figs. l and 4 of the drawing. A pin 34 mounted in the body of the shuttle extends over the lug 33 and securely locks the device in place.
It will be noted that, by the provision of the rubber facing 3| on the device, it is unnecessary to widen the upper portion of the recess in which the end portion of the bobbin, adjacent the ange 2|, is seated as the rubber facing will give sufficiently as the spindle with the bobbin mounted thereon is moved inwardly to operative position, or outwardly to the doing position. By reason of the resilience of the rubber facing and the pressure thereby exerted against the inner face of the flange 2| at the end of the bobbin, the same Will assist in maintaining the spindle in its normal axial position within the shuttle body.
I claim:
1. In a loom shuttle, the means for holding the bobbin against longitudinal movement within the shuttle body comprising a rigid plate member mounted in the shuttle body and having a facing of yieldable material permitting the bobbin to be swung into position and engaging a portion of the bobbin when said bobbin is in operative position within the shuttle body, and means for securing the plate member in position in the shuttle body.
2. In a loom shuttle having a spindle member for supporting a bobbin in normal operating position within the shuttle, the means for holding the bobbin against longitudinal movement on the spindle comprising a rigid U-shaped plate memer positioned in recesses in the side walls of the shuttle body having a facing of yieldable material permitting the flanged bobbin to be swung into position and engaging the inner face of the ange of the. bobbin when said bobbin is inoperative posi-tion on the spindle and withinthe shuttle body, and means for securing` said plate member in position in the shuttle body.
3. In a loom shuttle having a pivotally..mounted spindle member for supporting a bobbin in normal operating position withinthe shuttle and which may be moved to dofng position relative thereto, the means for holding thebobbin against longitudinal-movement on the spindle comprising a rigid U-shaped plate member positioned in recesses in the side walls of the shuttle .body having a facing of. yieldable material permitting the flanged bobbin to be swung into position and engaging the inner face of kthe rflange of the bobbin when said bobbin is in operative position on the spindle and Within the shuttle body.
4. In a loom shuttle having a pivotally mounted spindle member for supporting a bobbin in normal operating position within the shuttle and which may be moved to doing position relative thereto, the means for holding the bobbin against longitudinal movement on the spindle comprising a rigid U-shaped plate member positioned in recesses in the side walls of the shuttle body having a facing of yieldable material permitting the flanged bobbin to be swung into position and engaging the inner face of the ange of the bobbin when said bobbin is in operative position on the spindle and within the shuttle body, and means for securing the plate member in position in the shuttle body.
5. In a loom shuttle having a pivotally mounted spindle member for supporting a bobbin in normal operating position within the shuttle and which. may be moved to. dong position relative thereto, the means for` holding the bobbin against longitudinal` movement -on the spindle comprising .a Vrigid U-shaped plate member positioned in recesses in the side walls of the shuttle bodyhaving a facing of yieldablematerial permitting the flanged bobbin to be lswung into position and engaging the inner face of the ange of the bobbin when said bobbin is inoperative position on the spindle and within the shuttle body, and means for securing the plate member in position in the shuttle body, said means comprising a forwardly extendingllug at the lowerend of the plate memberfand a pin extending through the body of the shuttle and engaging said lug.
