SPECIFICATION forming part 0f Letters Patent N0. 601,215, dated March 22, 1898. Application led October 5 1896. Serial No. 607,972. (No model.)

To all whom t may concern:

Be it known that CHARLES T. SrnrsoN, deceased, late a citizen of West Hanover, in the county of Plymouth and State of Massachusetts, did invent certain new and'useful Improvements in Hose-Looms or Machines for Making Tubular Fabrics, of which the following, taken in connection with the accompanying drawings, is a specification.

v This invention relates to hose-looms or machines for the production of tubular woven fabrics; and it lconsists of certain improvements in the construction thereof, as will be hereinafter fully desc'ribed,land pointed out in the specification and claims connected hereto. y

This invention is illustrated in the accompanying drawings as follows:

Figure lis a plan view. Fig. 2 shows on the left of a vertical center line a vertical section on the dotted line l and l in Fig. l. On the right of the center line it lshows a vertical elevation. Fig. 3 is a vertical elevation of the outside of one of the shuttles, looking toward the center of the machine. This view shows the top edge of the frame of the machine A,

the grooved or double conical rollers in which the shuttle is guided,the lling-thread-tension device, weave-pin, and beating-in hook. Fig. 4 is an end elevation of this same shuttle, but showing also a section of the central drivingshaft E of the machine, the stationary gear Gr,

the driving-arm F, which is attached to a faceplate fastened to the shaft E, and the two small gears g' and g2, meshing into the stationary gear G and giving a rotary motion to the driving-Wheel s6, which in turn drives the small wheel S5 fastened to the shuttle. This view also shows the upper part of the stationary central shaft U, weaving cone T, and relative position of the weaving-*point and spreader thereto. Fig. 5 is a plan View of a section of the central hollow'shaft, the stationary gear G, the driving-arm F, and the small gears and wheels for transmitting power to the shuttles. Fig. 6 is a plan view of one of the segments of covering-plates for the top of the main frame A and which acts as a guide for the warp-threads, which are reciprocated back and forth by the heddles in the radial slots shown in this plate. This plate is designed to prevent the warp-threads from being carried along by the shuttles in the direction of their movement and thereby becoming en-` tangled one with another. Fig. 7 shows a plan and vertical side elevation of the tension devices n, consisting of a pivoted guidelever through eyes in the end of which a warpthread is passed and a spring fastened to the stand supporting this pivoted lever and pressing up against a presser-linger interposed between the ends of this spring and the fulcrum of the pivoted lever, so as to bear ,upon the warp-threads at this point.

ThisV device consists of a main annular frame A, which is supported on the legs B and supporting above it the take-up frame O. Passing horizontally through the annular frame A are the heddle-frames D, which are actuated by means of the rods d, connectinglinks ol', double-throw cranks D2, which in turn receive their motion through the Vertical shafts cl3, by means of the gears d4 and the gearv d5, which is keyed to the main shaft E of the machine. This main shaft in turn receives its motion through the bevel-gears e and e2 and the driving-shaft e4. On top of the main frame A are three shuttles S S S2, the last-named shuttle S2 being shown in dotted lines in Fig. l for sake of clearness of illustration of the shuttle-actuating mechanism beneath. These shuttles are guided in their annular path around the top of the frame by the grooved rollers R, whose shape is that of two truncated cones joined together at their smaller ends. On top of the shuttles S, S', and S2 are the bobbin-carriers s', which carry the bobbins s2, tension-rollers s3, and weavingpoints s4. These shuttles S, S', and S2, which are three in number, receive their motion through the medium of the rollers S5 and s6. The rollers s6 are carried by the arms F,

formed integral with the frame F2, which is secured to the annular plate Ff, keyed fast tothe main shaft E, before referred to. The arms F revolve with the main shaft E from left to right, and the rollers s6 come up be- IOO the warp-threads between the rollers 35 and SG. These rollers s" receive a rotary mot-ion by means of the gears g and g2, the gear g2 being in mesh with the large stationary gear G, which is secured fast to the top of the annular frame A. rlhe frame orstand Il, which carries the small vertical shafts d3, is also secured to the main annular frame A. The take-up rollers J and J receive their motion through the gears K and K2, the gear K being actuated by means of the worm-wheel 7c3 and worm 7d, which is keyed to the shaft 7&5, which is in turn driven through the bevelgears k and k7, which latter in turn receives its motion through the vertical shaft L and ruiter-gears Z and Z2, which latter gear receives its motion from and is keyed fast to the shaft c". The take-u p shaft L5 is also provided with a hand take-up wheel m and engaging clutch-face ym, which meshes with the face of a similar clutch-face m", which is an integral part of the bevel-gear k6. The engaging clutch-face m is held in contact with the opposite clutch-face m2 by means of the spring m3. The gear 7n is not keyed to the shaft lo, but drives through the medium of the clutchface m, which is splined upon the shaft 755 and has a lateral motion upon this shaft.

Upon the lioor between the the legs B are the warp-tension and controlling devices comprising tension-frames N, which carry the tension-lingers n, which are preferably constructed as a pivoted lever 0L,through eyes 112, in both ends of which the warp-threads are passed, and the tension is produced by a spring u underneath this lever bearing up against the warp-threads. These levers are pivoted, so as to insure their being kept in line with the axis of the warp-threads. The warp-threads O and O come up through the floor beneath the machine, pass through the tension-fingers n up over the take-up rods P P2, down between the rods P2 and P3, through the take-up weight Q, over the rod P3, under the rod P1, then up through the eyes in the heddles dfin the heddle-frames, then through slots in the guide-plates a, (see Fig. 6,) which form the top to the annular frame A, passing either side of the shuttles S and S, being distended on the outer side, so as to clear the bobbin s2 by the spreader 57. The point of this spreader is designed to enter between the opening of the warp-threads in advance of the shuttles, force them apart, so as to preclude their catching upon any point of the shuttle,and to allow them to fall back in place over the tail of the spreader, as shown, and so to the weaving-points s1, where they are brought in contact with the weaving-pin T, which is carried bythe internal rod U, inside of the revolving shaft E.

The illingthreads O3 are wound on the bobbins .S2 and pass through the guide-eyes s, guide-eyes s", tension-wheel s3, and so to the weaving-points sl, where they are forced in between the warp-threads O and O', the fabric being drawn upward by the take-up rollers J and J2. There are `three sets of shuttles and shuttle-driving mechanisms, as described above, and sixv sets of hcddlcs working in alternate order with the set of heddles immediately preceding and succeeding them. rlhe object of the design of this machine is to so construct a machine that all of the reciprocating parts occupy as low a position as possible and also to make them as direct acting and compact as possible, so as to both concentrate and lower the center of gravity of the machine, thereby insuring its stability and permit of its being run at very high speed with a minimum amount of jar and oscillation. 'lo insure this result, the heddles, heddle-actuating mechanism, main driving mechanism, warp-thread take-up,and tension are all placed below the path of the shuttles, there being nothing above the horizontal line of the shuttles excepting the takeup frame C and its mechanism, which is made as light and simple as possible, so as not to carry much weight up into the air and also so as to present the least-obstructed view and freest means of access to the weaving-point of the fabric being constructed, which is therefore at all times easily accessible for the inspection of the person in charge of themachine. It is also designed to accomplish, by the use of the three or more shuttles, a machine which will form tubular fabrics of comparatively small diameters with the utmost rapidity. In fact, the whole design of the machine is to secure one which can be run at the highest possible speed and produce the greatest amount of fabric in a given time.

Having thus fully described the construetion and method of operation of this machine, what is desired to be claimed and secured by Letters Patent is as follows:
