LOOM ATTACHMENT.

To all 'whom it may concer/1L.'

Be it known that I, SOLOMON KENDRICK, a citizen of the United States, residing at Rochester, in the county of Monroe and State of N ew York, have invented certain new and useful Improvements in Loom Attachments; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in attachments for looms, and is especially designed for use in connection with looms for weaving silk and cotton elastic and nonelastic narrow fabrics.

One of the primary objects of the invention is to provide certain improvements in connection with the mounting and operation of the reeds cooperating with the shuttle mechanism and the woven portion of the fabric to allow ample time for the shuttle to travel home in passing through the shed, and also to effectively engage and set the weft threads, the whole coperating to produce a loom for the manufacture of narrow fabrics capable of greater production of a better ar- Y ticle than heretofore.

The particular features of novelty are pointed outf in the, appended claims, and while the invention is not restricted to the exact details shown and described, still for the purpose of disclosure reference is had to the accompanying drawings illustrating a practical embodiment of the invention, in which like characters designate the saine parts in the several views, and in which Figure l lis a perspective view of a narrow fabric loom with the invention applied theie- A to, and with some parts cleai'nessof illustration. vation of same, and Fig.

forming a part of automatic means coperating with said shipper 9 to provide an emergency stop motion, the details of which form no part ofthe present invention, and which are specifically shown and described in rmy former patent, No. 871,704, patented Nov. '19. 1907.

While the and shuttle arrangement-have certain decided advantages, being for a separate invention, they form no particular part of the present invention and have only been illustrated broadly, and will only be referred to bi'ieliy.

11 designates a shuttle race affixed to the loom frame in front of the several harness, and provided between the blocks 12 with openings forming a space to allow the reeds to pass back and forth.

The shuttles are designated at 13, and are of oblong shape, tapering to the front. The inside face of the shuttle is oval and of suf-, ficient depth to cover t-lie base diameter of the cones ll, constituting the bobbins of filling material, the shape of the shuttle protecting the cone of material from engaging the lwarp threads. No particular means is shown for imparting movement to the sluittles, it being understood that this may be done in the usual way.

15 designates the hatten which is suitably mounted on the upper member 16 of a swinging frame formed by pivotally supporting the member 16 on the vertical bars 17 pivotally supported at their base. The upper member 16 is connected to a pitman 1S, pivoted at one end thereto, as at 19, and at its other end pivoted to a crank arm 20 on the loose driving wheel. I

Referring to the particular vfeatures of present invention', 2l. designates guide blocks mounted on the hatten and coperating with the reeds vto form a guidevvay therefor. y

The reeds consist of the ordinary form of vertical members 22, b iit are provided at their base with horizontal -extensions 23 slidably mounted, transversely of the hatten 15,`inl relation to the blocks 21. heronnections between the blocks and the base member 23 may be any suitable form of sliding connection, such as tongue and particular form of bobbin cone groove, and in the drawings the blocks are shown as being provided with tongues 24 operating in longitudinal side slots 25 in the reed base. The forward end of the reed base 23 is also slotted vertically, as at 2G, and within said slot is suitably mounted one end of a slotted finger 27, shown in detail in Fig. `3, the slot in the end of said finger being curved and formed with an internal Ishoulder 28. In the drawings, a pin or roller 29 is illustrated as extending transversely of the slot in said reed .base and riding in the curved slot of said finger. lt will be understood, of course, that there are as many slotted fingers as there are reeds, and these fingers are carried by a transverse oscillating bar 30 operated by a short crank arm 3l carried at one end and connected by the vertically-operating rod 32 with the long arm 33 of a bell crank lever, pivotally supported at the base ,of the machine, and the short arm 34 of this bell crank lever be-L ing connected by a connecting rod 35 with an operating lever 36 pivotally mounted at its base, as at 37, and the uppervend of which cooperates witha cam member 38 controlled by the movement of the loose driving wheel. The batten may be recessed at 31a to allow of the free movement of the short crank arm. This cam member is preferably of oval shape, as shown, the nose of the cam being disposed in the same line as the crank arm 2O and the normally dead or butt surface, indicated in dotted lines at 39, being diametrically opposed to the nose. Instead of forming a cam with the dead surface 39, however, it may be desirable to extend this surface a farther distance from the center which will form a'circular cam face for a purpose hereinafter referred to. This circular cam face is indicated by the dotted lines at 40. lIt will be understood that while the nose of the cam 39 is shown as disposed in line with the crank arm 20, the nose of said cam may be arranged out of line therewith to regulate the movement of the reed with relation to the batten at the beginning of the forward stroke or as the going parts are leaving the race.

lt will be obvious in operation and with the parts in the position shown in Fig. 2, upon a continued movement of the driving wheel in the direction indicated by the arrow, with the lever 36 about to engage the dead surface of the cam between the positions indicated at a and Z) that. the lever 36 will have receded to its normal forward position, the slotted finger 27 moving rearfwardly, as indicated by the dotted arrow,

which will shove the reed rearwardly. a. limited distance, the pin or roller 29 ri ing down toward the lower end of the slot. As soowas the lever 36 strikes and is riding Ilation to the shuttle race.

over the dead portion a-b of the cam the reed remains stationary relatively to the batten, and the batten and reed move rearwardly until the point Z) on the cam surface is reached, when the connecting parts between the lever 36 and the reed base will tend to move the reed forwardly, but as the batten is still moving rearwardly the reed practically remains stationary with rerl`he batten continuing to move rearwardly projects the forward end of the reed base beyond the batten owing to the sliding connection between the reed base and the guiding blocks. That is to say, as the batten approaches the rear end of its stroke the movement of the reed which normally projects a few inches rearwardly 'of the batten is retarded and practically stopped when in a position at the rear of the shuttle race. Thisretardation, of course, is of short duration, and when theeXtreme -position of the nose of the cam 38 is in engagement with the lever 36 (with the crank arm 20 on the rear 'dead center) upon continued movement the batten start-s forward again, but while the cam engages the lever from the center of its nose to the position c the reed practically remains stationary and the distance, between the stationary reed and the receding batten, increasing, their is, during this period, caused a substantial dwell, duringl which dwell the shuttle passes through the shed in front of the reed before the reed starts to move forwardly on its return stroke, which forward movement of the reed will begin when the cam reaches the position c. Until the position d is reached the 100 reed will continue to move conjointly with the batten, but projecting rearwardly thereof. When. the position d of the cam` is reached, owing to the cam surface 40, the reedl starts to move forwardly again inde- .105 pendently ofthe batten, which is still moving forwardly, and when the central portion of the rear end of the cam is reached the slotted arm 27 is disposed substantially in the position shown in Fig. 3, so that the 110 reed is temporarily locked to the batten by the interposition of the shoulder 28 behind the roller 29. At this position the reed is pressed against the last weft thread or shoot and it remains there momentarily until ,the regular makes of narrow fabric looms by simplyV changing t-he crank' arms and 125 batten.
