To all whom it may concern:

Be it known that we, NORBERT FoERsTER, DANIEL JOSEPH CAREY, and WILLIAM ASTON FOSTER, citizensof the United States, residing in the borough of Manhattan, city, county and State of New York, have invented certain new and useful Improvements in Shutpurposes.

tles, of which the following is a specification.

This invention aims to provide'an improved loom-shuttle especially designed for operating or controlling mechanism for stopping the loom or for supplying new weft or for similar Looms having mechanism ofthis ind are well known. The device provided for this pur ose is very simple in construction, is easil in existence, operates with great certainty,

' and is arranged to yield when it engages the loom mechanism improperly.

' Various other points of improvement are specified in detail hereinafter The accompanying drawings illustrate embodiments of the inventlon.

Figure 1 is a plan With the thread in the .shuttle nearly exhausted, certain parts'being broken away to illustrate the construction clearly. Fig. 2 is aplan, partly broken away,

showing a full quill of thread on the spindle.

Fig. 3 is a longitudinal section omitting cer- Fig. 4 is .a side elevation. Figs. 5 and Gare plans tain parts for the sake of clearness.

' similar to Figs. 1 and 2, illustrating another construction. Fig. 7 is asection 1 approxilmately on the line 7 7 of Fig. 5. Figs. 8 and 9 are respectively a plan and an inside face elevation of the mechanism-controlling lever ,of another construction- Figs. 10 and 11 i ,are res .ectively a plan and a longitudinal sec- -..tion 0 another style of mechanism-controlling lever, Fig. 11 being taken on the line 11 11 The shuttle A is preferably provided with I a spindle B,-pivoted at its square'heelC, so

,form. An important feature of the invention isthat an' arm' which controls the'movement that it may swing in a vertical direction and .may be turned up to facilitate the application of a quill on the spindle. The'usual flat spring may be employed for holding it firmly in either position. This is a common form of shuttle. The invention may be applied either to this form or to any other suitable y applicable toshuttles already -der the operation certain.

of the mechanism-controlling device is pivotally connected to the latter, so as to ermit of the use of the invention with a shutt e hav ing a vertically-swinging spindle and so that the arm may be movable with the spindle to facilitate the application of the quill with the mechanism-controlling device in its inoperative position. The mechanismcontrolling device is preferably a lever swinging horizontally, and the controlling-arm is preferably a spring which is connected at one end to the shuttle-spindle. Preferably, also, means are provided for automatically moving the device to .its inoperative position on the turning-up of the spindle. According to this improvement we are enabled to pivot the mechanism-controlling lever separately from the spindle,'even though the arm for controlling said lever moves with the spindle. In looms having'mechanism controlled by the shuttle this control is exercised usually at only one will be the advance end as. the shuttle enters the. special box above referred to.

sures that the device shall always enter the shuttle-box sufficiently to be effective, even This inwhen the shuttle enters only a slight distance,

as is sometimes the case. A point of this invention is in forming the mechanism-controlling device with an abrupt shoulder in the direction of said forward or advance end of the shuttle and tapering in the opposite direction.. By thisconstruction the device will securely engage the coacting elementson the shuttle-box or on the side of the 100111 upon which the device operates and will thus'renhand, if'theshuttle should completely pass said coacting elements before the thread is exhausted sufiiciently to actuate the mechanism-controlling device the face of the device tapering in the opposite direction permits the device to pass said coacting elements On the other 9 11 9 rswr i hw W v nju i a to pass any other projecting part of the apparatus or any projecting threads without injury. The pivot of the swinging lever which preferably constitutes the mechanismcontrolling device is in advance of the abrupt shoulder, so that the lever is subjected to a direct pull in operation, which holds it firmly in position, the pivot being mounted at one side of the spindle and as near the side of the shuttle as practicable in order that the strain shall be a direct pulling strain as nearly as possible.

Referring now to the embodiment illustrated in Figs. 1 to 4, the mechanism-controlling device is a horizontal swinging lever D, pivoted at E, having at its rear end a projecting portion with an abrupt shoulder F and a tapered end G. In dotted lines is shown a member H, representing any suitable element on the shuttle-box or loom with which the lever D coacts. The arrow shows the forward direction in which the shuttle is moving, and the abrupt shoulder F of the lever will engage the member H and the lever will be pulled backward almost in a straight line from its pivot, so that the tendency to deflect laterally will be very slight and will be overcome by the friction of the engaging surfaces. If

the lever should meet with any obstruction in the movement of the shuttle in the opposite direction, the tapering face G will immediately cause the lever to be pressed inward, so as to readily pass such obstruction. In order to swing the lever D from its operative position, Fig. 1, to its inoperative position,

ig. 2, an arm J is connected to the lever and l is connected at its other end to the spindle B.

When the quill K, containing a considerable quantity of thread, is on the spindle, the thread presses the arm J inward and pulls the lever to the position of-Fig. 2. When the thread runs out or nearly out, the arm J is released and the lever is thrown outward. The arm J is preferably a spring soldered or otherwise fixed at one end to the spindleB and connected at its other end to a pin L, which reciprocates in the hollow shaft M of the spindle and which is swiveled in the lever D to permit the pin to rotate. Preferably a key or enlargement N is formed on the spindle at the point of connection of the arm J to form a guide fitting in the slot of the quill K, as shown. As the spindle B is turned up to receive a new quill the arm J moves with it, the pin L turning to permit this. At the same time a wire cam O, which lies in the path of Y the arm J, forces the latter inward, carrying with it the pin L and the lever D. Pins P may be provided on the heel of the spindle, engaging the intermediate part of the arm J to assist in moving it evenly with the spindle B, or the pins P may be relied on alone to swing the arm J up and down, said arm being not otherwise connected with the spindle.

The pivotal connection of the arm J with the mechanism-controlling device may be effected in various ways, it being only necessary to this feature of the invention that the arm shall be capable of swinging with the shuttle-spindle and shall also move in and out laterally with the mechanism-controlling device. For example, as shown in Fig. 5, the end of the arm J may pass through an eye Q of a pin L, which is swiveled in the lever D. We have shown in this case a quill K of paper, the arm J being soldered in a groove in the spindle to permit the use of such a quill and the pins P being also dispensed with.

In Figs. 8 and 9 there is shown a fixed eye R, arranged at such an angle and of such a size that the arm J may pass through the same whether standing in the horizontal position (shown in full lines) or the substantially vertical position (shown in dotted lines) without interrupting its sufficient engagement with the mechanism-controllin g device. Figs. 10 and 11 show anotherconstruction serving the same purpose. The lever D is formed with a slot S, in which the arm J lies in either a horizontal or a vertical position and in which it moves the lever either inward or outward as the arm itself is moved.

Though we have described with great par ticularity of detail certain embodiments of the invention, yet it is not to be understood that the invention is limited to the specific embodiments disclosed.

Various modifications thereof in details and in the arrangement and combination of the parts may be made by those skilled in the art without departure from the invention.
