HUGH ROBERT ROSS in BELFAST (Ireland). Revolver shooter change.

Patented in the German Empire on May 6, 1898.

The present invention has the purpose of changing the shooters when breaking or Absence of the weft thread through the intermediary of the guns fork by a peculiar one Mechanism to effect, whereby the removal of the used shooters means one device operated by this mechanism takes place at the same time.

In the accompanying drawings, in which loom parts required for a better understanding are brought to view, Fig. ι is a front view,

Fig. 2 is an end view,

Fig. 3 is a plan view,

Fig. 4 is a longitudinal section of the turret contactor box and

FIG. 5 shows a cross section of the same and of the shooter magazine along line xy in FIG. 4.

The revolver shooter box is provided with slides and thumbs for removing the empty shooters, as well as with levers which connect the firing fork to the drive device for the revolver shooter box, through which the box rotates and another shooter breaks or goes on fire of the firing thread is automatically fed from the container H by the slide h , which is actuated by the contactor box when it is turned.

If the firing thread breaks, the firing fork acts on a hammer lever E, the movement of which is transmitted through the support d to the rotatable lever T ¹ and crank T , which now brings the sinker P ¹ into engagement with the oscillating lever 0; this continues its movement again by means of the plate P ¹ and the rotatable lever O on the hook rod P , so that the contactor box makes a rotation. By the same operation, the disk S ^{3 is} brought into contact with the lever V ¹ which, after the partial rotation of the shooting box K has taken place, activates the slide h by which one of the gates G housed in the fixed container H is driven out .

Each box k of the revolver K has one or two slides L at the bottom, by means of which the shooters are driven out. When the revolver rotates, the slides L are actuated by a firm thumb M on the shaft Z ^{1 of} the revolver. Thumb M drives the slide L forward as soon as the shooter box k is turned over for the purpose of removing the shooter. The slider and thumb act directly on the shooter and remove him.

The revolver has a cylindrical jacket M ¹ , which encloses the shooter and holds it in position in the box k. The sheath has a slit m above, the resilient edges to the boxes ¹ k partially protrude, for the purpose to keep the shooter during operation of the chair in a suitable position.

The crank T is connected through the rod t to the swinging lever T ¹ , the upper end of which is actuated by the support d of the shooting fork D. The oscillating hammer lever E is actuated in a known manner by the thumb disk e ¹ (FIGS. 1 and 3); he catches the hook at the end of the

(e.g. edition, issued on / January 7th

fork, as soon as the weft ripens, whereby the support d is withdrawn and a movement of the lever T ^{1 is} caused, which is transmitted by the crank T to the plate P ¹ , which in turn now comes into action by means of the pin o ^{1 on the lever o.}

Of the. The slide h , which is reciprocated in the container H , is actuated by the levers V , which advance the lowermost riflemen when required. The levers V are moved in one direction by the lever V ¹ , which is connected to the former by means of a spring or a hinge ν , and in the opposite direction by the spring v ^1. The lever V ^{1 is} depressed by the thumb disk s ¹ and disk s ″ on the shaft S. Disks S ¹ S ″ move in such a way that they grip the lever V ¹ every time the hook rod P and the plate P ¹ rotate the contactor box can be operated in the following way:

The lever O has an arm W with a pin or tenon w at its end which engages and lifts a hinge w ¹ and engages a head or runner w " with a thumb ^{washer s 3} on the thumb shaft. The hinge w ¹ is also connected to the lever W ¹ , which is rotatable at its upper end at a fixed support point; the action of the thumb disk s ³ on the running piece w " removes the joint w ¹ from the thumb. Lever W ¹ is in contact with the disk s " , and as soon as this disk is moved by the thumb s ³ , it slides along the thumb shaft S until the disk s ^l above the lever V ¹ is in the position in which this is pressed down; spring w ^s leads the lever back again.

The arrangement of the levers is such that the movement of the slide h begins at the moment when the crank F is almost at the end of its movement towards the outside and the shooter box K is almost in contact with the shooter container or magazine H.

Claims (1)

Patent-An saying: A revolver-shooter change, in which the shooters are changed through the intermediary of the shooting fork, characterized in that the shooting fork acts by means of a support (d) on a rotatable lever (T ¹ J and a crank (TJ) and thus the exchangeable plate (P ¹ J engages with the knife lever (oj , the movement of which then causes the rotation of the revolver-contactor box and at the same time brings rotating disks (s ¹ s ") into contact with a lever (VJ , whereby this, after the partial rotation of the contactor box (KJ completed, a shooter slide (hj activates , while at the time of the rotation of the revolver shooting case, a slide (Z,) located in the case (k) and moved by a fixed thumb (MJ ) causes the used shooter to be driven out. For this purpose 2 sheets of drawings.
