Application filed December 29, 1921.

To (LZZ whom, c'zf may concern:

Be it known that I, EUGENE C. Airsnn a citizen of the United States, and aresident of Boston, in the county of Suffolk and State of Massaclnieetts,. have invented anew and useful Improvement in Shuttle Boxes, of which the following is a specification.

My invention relates to shuttle-boxes and more particularly to such boxes made of pressed sheet metal. The cast-iron shuttleboxes now in general. use are subject to certain defects and limitations, among others the excessive cost of the same, due chiefly to the labor involved in dressing and machining the castings; their liability to crack under certain conditions as for instance when the box is moved vertically to change the thread at the instant that one of the shuttles is projecting from the rear end thereof, whereupon the impact of such shuttle with a fixed part of the loom will fracture the relatively thin casting at the rear end thereof; and their comparatively short life due to the fact that when the guide members, which are cast integral with the box, become worn. the device must be discarded.

The general object of my invention is to provide a. shuttle-box made entirely out of pressed sheet metal whereby the foregoing disadvantages inherent in the cast iron boxes are eliminated.

special object of my invention is to provide such pressed sheet-metal shuttle-box in which the several elements thereof are formed separately of pressed sheet metal and then suitably assembled as by riveting or spot-welding whereby the labor cost is reduced to a minimum and the device may be produced at substantially one half the total cost of the cast-iron boxes of the prior art.

Another objectis to produce a. shuttlebox which. is much stronger than the castiron boxes aforesaid. and to provide the rear end thereof with bracing: members whereby the box is so greatly strengthened that an ill-timed vertical movement thereof with a shuttle projecting from the rear end will not cause the breakage of the same.

still further object is to provide the Serial No. 525,712.

the life of the device may be greatly pro longed by the simple expedient of replacing such guides as they become worn;

Various other objects and advantages of my invention will hereinafter more fully appear, and the distinctive features of novelty will be pointed out in the appended claims.

With the foregoing objects in view invention comprises as its salient features a box member pressed out of a suitably shaped strip of sheet metal, preferably hard malleable steel, to form a base and two parallel sides at right angles thereto, a partition parallel to said sides and located midway between the me to form with said sides two shuttle compartments, the said partition being suitably attached to said base, as for example, by being headed thereinto, front and rear top pieces suitably attached to the respective ends of the boxes, the usual presser arms hingedly connected to the rear top piece and having their free ends resting on the front top piece, springs co-operating with said presser arms, respectively, to maintain the free ends thereof against the front top piece, stop member secured to the front top piece for limiting the upward moven'lent of said presse 1 arms and nonintegral guide member secured to said top pieces for co-operationwith the usual guide ways along which the shuttle-box has intermittent vertical movement.

A practical embodiment of my invention is shown in the drawings which accompany and form a. part of thisspecification, although it will he understood that various modifications may be made therein without departing from the invention as defined by the appended claims.

in the drawings Figure 1 is a plan view of a shuttle-box involving my invention;

Fig. 2 i a side. elevation of said shuttlebox: I

Fig. 3 is a plan view of the under side of said shuttle-box as it would appear if it were rotated about its longitudinal axis one hundred and eighty degrees from the position shown in Fig, 1;

4 is a vertical section taken on the provided with sides 22, 23 formed this purpose.

8 is a fragmentary vertical section rearward end of one of said presser 9 is a side elevation of the front top 10 is a side elevation of the rear top therewith, said box member beingout of a strip of sheet metal such as hard malleable steel. Dividing the box member into two compartments is a partition secured in any suitable manner to said base,

' and in the present instance the lower edge of said partition is provided with tenons 25 headed into openings 111 said base. said partition bein aarallel to the sides of the box 'member and arranged midway between the same.

Secured to the front end of the shuttlebox is a top piece 26 having two pairs of downwardly disposed side members 27, 28 which are arranged over the outer surfaces r of the sides 22, 28 of the box and are secured thereto in any suitable manner, as for ample, by spot-welding. riveting, etc, said top piece, aswell as the other members of the shuttle-box being shown in the present instance as spot-welded thereto as indicated at 29. The forward pair of sides 27 are bent laterally thereto and form flanges 30, 30 to which the front guide member 31 is secured by any suitable means. headed rivets 32 being shown in the present instance for w Extending upwardly from the sides of the front top piece 26 are arms 33 to which the combined guide and stop member is attached. the said combined guide and stop niember having its outer sides 36 spot-- welded or otherwise secured to said no standing arms and its intermediate sides 37. 37 extending downwardly to the upper face of the front top. piece.

Secured to the rear end of the bOXZHQUT her is a top piece 38 having the hinge knuckles 39 of a hinge formed integral with its forwardedge. In the present instance there are three such hinge knuckles each formed by bending a strip integral with and extending forwardly from the top member 38 back on said top member and spot-weld ing the same thereto. I

The two sides of the top member 38 are bent laterally near the rearward end thereof to form the flanges l0 for supporting the rear guice member 41, said rear guide member being secured to said flanges in any suitable manner as for example by the headed rivets 4-2. in the present instance the sides 22, 23 of the i103. member are upwardly inclined at their rearward ends, conforming to the shape of the rear top piece 38, which as shown has its depending sides 43 in contact with the sides of the box member and spot-avoided thereto.

The presser arms 43; 43, are pressed channel-shaped out of sheet metal ant a hinge knuckle A is formed on the rear end of each by bending tiie strip reversely on itself and spot-welding the same as indi cated at 15 to the web of the channel. The pintle having a headed end 4'7 passes through the knuckles 39 and 44. thereby hingedly connecting the presser arms to the rear top ooir a cotter pin 48 maintaining said pintle in position.

The forward end of each presser arm is bent reverscly on itself and spot-welded to the web as indicated at 4.9, and is enlarged as shown at 50 to form a bearing surface for a spring-pressed loom member (not shown) which. exerts pressure on said arm to force the latter against a shuttle placed in one of the compartments of the box. Additional pressure is exerted on. each presse-r arm by a leaf spring 51 having rearward end attached to the rear top box by a screw 52 and its free end in contact with thepresser arm.

As will be clear from vFigs. l and 4. the intermediate sides of the combined stop and guide member are arranged between. the PYPSSQTHYZDS near the forward end thereof.

In order to strengthen the rear end of the box a brace is placed on each side of and spot-welded to the partition 24.- under the rear top piece and is secured to the latter by spotwelding and by the screws 52, each said brace havingahorizontal portion in c: itact with the under surface ofthe. rear top piece. a vertical portion in contact with said partition. and an inclined portion integral with and connecting the said portions 54- and Secured to one side of the lOOX is a channel-shaped stiffening member 56 extending substantially throughout the length of the box and having a threaded nut 57 located iii-- termediate the ends thereof and secured to the flanges of said stiffening member by spotwelding or otherwise. the shuttle-box being mounted on a stem threaded to said nut.

It willv be clear that my improved shuttleboX may be formed with as many shuttle compartments as desired by the simple expedient of using a plurality of partitions.

For example it four shuttle compartments messes are desired, the box member will be divided into four compartments by means of three partitions.

If desired the upper edge of the partition 24- may have one or more tenons projecting therefrom near the ends thereof for co-operation with openings in the upper faces f the top pieces. As indicated at 58, 58, two such tenons pass through openings in the front top piece 26 and project slightly above the upper face of said top piece, and as shown at 59, one such tcnon is headed into an opening in the horizontal portion of the rear top piece 88. i

A shuttle box can be constructed in ac cordance with my invention at substantially one half the cost of the cast-iron shuttle boxes in general use today; by virtue of the bracing arrangement under the rear top piece, it is practically impossible to fracture the device by the impact of a projecting shuttle with any portion of the loom; and by virtue of the non-integral guide members 31, 4.1, which may be taken off by clipping off the heads of the rivets 82, 4:2, respectively, and new guides substituted therefor, the life of my shuttle-box may be prolonged practically indefinitely.

Having thus described an illustrative embodiment of my invention without however limiting the same thereto, what I claim and desire to secure by Letters Patent is 1. A. pressed sheet-metal shuttle-box comprising a box member having a base and sides formed integral there-with, a partition parallel to said sides and located midway between the same, means securing said partition to said base, a top piece secured to the forward end of said box, presser arms each having its forward end resting on said top piece and a combined stop member and guide for limiting the upward movement of said presser arms, said stop member being secured to said top piece.
