Application filed April 21, 1911. Serial No. 622,448.

To all whom it may concern: The base 10 may be of any dimensions, Be it known that I, MARTIN B. ZIMMER- i and from the end portion of the base a tubu- MAN, a citizen of the United States, and a lar pillar 11 extends upward. Said pillar resident of Lewisburg, in the county of 1 supports an end portion of a horizontal bed Union and State of Pennsylvania, have in- A, and an end portion of said horizontal vented a new and Improved Machine for bed, or that end which is adapted to sup- Inserting Diagonal Strands in \Vovcn-Cane y port the working portions of the machine, Fabrics, of which the following is a full, is in the form of a diamond-shaped table, clear, and exact description. 1 the points whereof extend in direction of The purpose of the invention is to prothe ends of the bed and in direction of the Vide exceedingly simple, positive and efi'ecfront and back thereof, as best shown in Fig. tive means for depressing the warp strands 2. In fact, an outer point of the table 12 and raising the weft strands in woven cane constitutes the working end of the bed, and fabric for the passage of a needle carrying a at the opposite end portion of said bed a diagonal strand, and to accomplish the oblongitudinal slot 13 is made. At the exject by the joint downward movement of a tremity of the slotted end of the bed a bar carrying guide pins for the fabric and grooved pulley 14 is mounted to turn horia parallel bar carrying depressingfingers for zontally upon the bracket 15 offset in dithe warp strands in connection with autm rection of the front of the machine from matically acting fingers that receive and the said bed, as shown in Figs. 1 and 2. hold elevated the weft strands. The needle-operating arm 16 is carried up A further purpose of the invention is to through the slot 13, and the lower end 17 of provideamachine of the character described this arm is widened and is rendered segwhich will be light, yet strong and compact mental, but at its lower curved surface is throughout its entire construction, and furprovided with teeth 18 as best shown in Fig. ther to provide an effective and reliable ma- 1. Said teeth 18 engage with the teeth of a chine, necessitating comparatively few parts rack 19 formed at the lower end of a standnearly all of which are readily accessible ard 20 which supports the slotted. portion of for inspection or repair. the said bed A. The needle-operating arm The invention consists in the novel con- 16 is guided in its movement and a pin 21, struction and combination of the several is secured to the said needle arm 16 and onparts, as will be hereinafter fully set forth gages with the under face of the bed A. and pointed out in the claims. The crank arm 22 extends up from the said Reference is to be had to the accompanyoperating arm 16 and is pivotally connected ing drawings forming a part of this specito the outer end of a needle B, which needle fication, in which similar characters of refis supported at its opposite or outer end in erence indicate corresponding parts in all a manner to be hereinafter described, and the figures. the eye 5 of said needle is formed at said Figure 1 is a side elevation of the im outer end, as is shown in Fig. 3. A second proved machine; Fig. 2 is a plan view therehorizontal peripherally grooved pulley 23 is of; Fig. 3 is a longitudinal vertical section supported at the outer end point of the table taken practically on the line 3-3 of Fig. 2; 12 by means of a bracket 24 attached to the Fig. 4 is a transverse section taken substantable; and said pulley 23 is secured to a tially on the line 4 4 of F ig. 1; Fig. 5 is a shaft 25, which extends down through the transverse section taken practically on the arm 24 and through a bracket 26 located line 5-5 of Fig. 1; Fig. 6 is a detail view below the said table 12, as is shown in Figs. of the stop employed in connection with 1 and 3, and said shaft 25 is provided with the operating mechanism for the elevating an attached pinion 27 fingers for the weft strands; Fig. 7 is a lon- A sliding rack C is mounted for movegitudinal section through a portion of the ment at the forward inclined portion of pin-carrying bar and cane fabric, showing the table 12, said rack having movement the warp strands depressed and the weft to and from the pinion 27, which pinion is strands elevated; and Fig. 8 is a plan view engaged by teeth 27 formed on the rack. of a piece of cane fabric, illustrating a few said sliding rack at its inner end being of the diagonal strands applied. provided with a handle 28. The rack is preferably L-shaped in cross section, and the teeth 27 are in its horizontal member; its vertical member is provided with longitudinal slots 29 which loosely receive bolts 30 or their equivalents, that extend into the said table, thus guiding the said slide. The movement of the said sliding rack C controls the movement of the needle B. and this is accomplished by means of an endless belt 31 that passes around the pulleys 1H and 23, and is attached in any suitable or approved manner at one of its stretches to the upper end of the needle-operating arm 16 as is best shown in Fig. 1.

A slot 33 is produced in the lower portion of the pillar 11, and through this slot a foot treadle or lever 33 is passed. being fulcruined at the rear of the said pillar and extending beyond its front. Said lever occupies a diagonal position relatively to the front portion of the base, so that the operator will have ready control of the sliding rack C. \Vithin said pillar this lever is connected by means of links 34 with a beam 35, which beam extends out through slots 36 in direction of the ends of the machine. and said beam 35 occupies a position at. an angle to the trcadle 33 and at a slight angle to the bed A. The beam 35 is held in an upper position by means of springs 37 attached to the pillar 11 and having upward hearing at the end portions of the beam as is shown in Figs. 1 and 3.

A bed plate 38 is located over the central portion of the table 12, extending in direction of the ends of the machine, and said bed plate is spaced apart from the table 12 by means of a. supporting bar 39, which is more or less diagonally located relative to the said bed plate and is longer than the bed plate, extending beyond its ends. In fact. the supporting plate 39 extends practically from one corner of the bed plate 38 to the opposing diagonal corner. The said supporting plate 39 has its upper end portions recessed or cut away as shown at 40 in Fig. 3. At opposite sides of the supporting plate 39, at its ends, two sockets 41 are formed, which sockets are secured also at their upper ends to opposite diagonal corners of the bed plate 88 as is best shown in Fig. 2.

A guide plate D is located above the bed plate 38. and is spaced apart therefrom, the said guide plate D being preferably transversely arched. its upper face being its convexed face. and the weft cane fabric H is made to rest upon this guide plate D while the diagonal strand H is being passed through the said fabric by means of said needle B. The guide plate D is provided with a series of upwardly-extending pins 42. Said pins are in two rows and are staggered in their general arrangement. the pins of one row being opposite the center of the spaces between the pins of the opposing row as is indicated in Figs. 4, 5 and T. The needle B in operation passes over said guide plate D which likewise may be termed a pin plate, passing between the rows of pins and through a suitable guide 6 located at the inner end of the said guide plate as is illustrated in Fig. 3. The guide plate D is further provided with a series of transverse centrally located slots 43, and said slots are so located that they are between two diagonally opposing pins 4-2 on said guide plate D as is best shown in Fig. T. so that a pin of one row and a diagonall opposite pin of the opposing row will be located between each two slots. The pins 42 are adapted to pass up through the meshes in the woven cane prior to a diagonal strand being woven therein. The said guide plate D is held yieldingly spaced apart from the bed plate 38 by means of downwardly-extending bolts -14, two of which are usually located adjacent to each end of the said guide plate. and said bolts are loosely passed through suit able openings in the bed. plate 38, and are provided with nuts 46 at their ends, so as to limit the upward movement of the said guide plate. Springs 45 are coiled around said bolts 44 between the two plates 38 and D, the spring serving to return the guide plate D to its normal position after having been relieved from pressure.

A depressing plate or bar E is located above the guide plate D; and said depressing plate 15 is provided with a series of downwardly-extending fingers 48 arranged to enter the spaces between diagonally opposing pins 4-2 to press and hold down the warp strands of the fabric when the depressing bar is carried downward taking with it the guide bar D. In order that the fingers 48 shall not slip during such operation a recess 49 is made in the bottom of each finger 48. capable of receiving a strand of the fabric. As the depressing plate E is forced. downward to depress the warp strands, retaining hooks F extend upward and rearward through the slots 43 in the guide plate D, which hooks receive and hold elevated or raised the weft strands adjacent to the pins 42?, as is shown best in Fig. 7; and at such time the needle B in passing between the rows of pins 4-2 will pass likewise between the depressed warp and the elevated weft strands, and thus weave the diagonal strand carried by the needle through the body of the fabric as is shown in Fig. 8, wherein the fabric is designated as H and the diagonal strands as H. These retaining hooks F are pivoted upon. two brackets 50 rigidly secured. to the body plate 38 as is shown in Fig. 3, and each retaining hook F provided with a reduced foot section just below its pivot, and said foot sections 51 enter recesses in the upper edges of curved cradle bars 52, the upper ed es of which bars are more or less concave as is shown in Fig. 5, for one bar. These cradle bars 52 are held properly spaced and have concerted action by front and rear tie rods 53 and 54, and sprlngs 55 secured to the table 12, or the supporting bar 39 at its rear, are carried up over the bed plate 38 to an engagement with the under surfaces of the said tie bars 53 and 54 for the purpose of keeping the cradle bars up to their work with reference to the hooks F. The normal position of the retaining hooks F is that shown in Figs. 4 and 5, wherein it will be observed that they are slightly below the upper face of the guide plate D, which is in its upper or normal position, and that the hooks have an upward and a forward inclination, whereupon by laterally moving the cradle bars 52 in a forward direction the said bars cause the said retaining hooks to assume a vertical position, said position being assumed as the guide plate D is carried downward, thus causing the said hooks to catch and receive the weft strands and hold the same elevated as the fingers 48 on the depressin plate E engage and hold the warp strands epressed. The movement of the cradle bars 52 forward and rearward is automatically accomplished preferably in the following manner: Rearwardly-extending links 56 are secured to the rear tie bar 54, usually at its end portions; and these links 56 are attached to a connecting rod 57, and said connecting rod is pivotally connected with downwardlyextending links 58. Said links in their turn are secured to a crank shaft 59, mounted to turn in suitable bearings 60 supported by the table 12, the crank arm 61 of the shaft 59 being given an upward and somewhat of a forward inclination as shown in Fig. 1. The shaft 59, which has a rocking motion, is limited in such motion by producing a curved slot 62 in one of the bearings 60 as shown in Fig. 6, and securing a downwardlyextending crank arm 63 to said shaft 59, the horizontal member of which crank arm has movement in the slot 62. The movement of the crank shaft 59 and the operation of the cradle bars 52 are accomplished by carrying the front or forward end of a lever arm 64 beyond and beneath the front or forward side edge of the bed plate 38 through one of the openings 40 in its supporting plate 39 as is shown in Figs. 1 and 3. This lever arm 64 is preferabl given a compound curve, and its rear en is pivoted to a standard 65 carried by the table 12 as best shown in Fig. 4, while a curved link 66 is attached to the lever arm 64 and to the upper end of the crank arm 61, the curvature of said link 66 being in direction of the forward or front side of the machine. The forward or front end of the lever arm 64 is received in a recess 67, produced at one side of the lower end of a trip finger 69 that is secured to the depressing plate E and extends down at the front or forward side portions of said depressing plate E, the guide plate D and the bed plate 38. The depressing plate E is operated through the medium of the treadle 33, and to that end downwardly extending rods 70 are attached to the end portions of said depressing plate E, which rods pass down through the sockets 41 and the table 12 to an engagement with the outer end portion of the beam 35.

In the operation of the machine, the parts being in their normal position best shown in Figs. 1, 3, 4 and 5, the cane fabric H. is threaded over the pins 42 on the guide plate D and the treadle 33 is pressed downward, which will carry the beam 35 down, placing its springs 37 under tension, and will also cause the depressing bar or plate E to be drawn downward until its fingers 48 engage with the weft strands of the fabric, whereupon the said plate E is continued downward until the guide plate D is depressed against the tension of its springs 45 far enough to uncover the upper ends of the retaining hooks F, bringing such portions in such relation to the weft strands of the fabric that when the hooks are moved rearward they will engage with said weft strands. Such rearward movement is brought about approximately when the depressing plate E has reached the limit of its downward travel by reason of the operating arm 69 forcing the front end of the lever arm 64 dowlr ward, thus pushing forward the connected cradle bars 52, thereby bringing all of the hooks F to an upper position, causing them to receive and hold elevated the weft strands. While the treadle 33 is yet depressed the slide 0 is operated past the needle B over the guide plate D between its rows of pins 42 and consequently above the warp strands and below the weft strands as is shown in Fig. 7. An end of the diagonal stand H is now passed through the eye of the needle B, as is also shown in Fig. 7. The operating mechanism for the needle is now reversed, carrying the needle back to its normal position and causing the attached diagonal strand to be drawn through the path of the needle. \Vhen this is accomplished the diagonal strand is caught in any desired manner, and the treadle 33 is releasedqvhereupon the springs 37 act to force the depressing plate E upward, and the operating arm 69 rocks the front end of the lever arm 64 upward, thus restoring the confining hooks F to their .normal position, and at the same time the springs 45 restore the guide plate D to its normal position. The fabric H may now be shifted to receive another diagonal strand, and the operation of the machine is repeated, as described.

It may be here remarked that the shafts 5T and 59 belonging to the controlling mechanism for the hook retaining devices F are steadied in their action by means of a spring f, shown in Figs. and 5.
