Application filed November 2, 192(). Serial No. 421,245.

To aZZ whom it may concern.

Be it known that I, JAMEs LEAMON REYN- oLi'is, a. citizen of the resident of Scottdale, in the county of VVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Weaving-Machines, of which the following is a specification.

The present invention relates in general to weavin machines, and more particularly especially adapted for screen fabric from relatively heavy The object of the invention is to provide a weaving machine of this character which is extremely simple and durable in construction, reliable and efiicient in operation and easy and inexpensive to manufacture and maintain and which is capable of effecting the speedy production of a high grade metallic fabric at a minimum cost.

Other objects and advantages of the invention reside in certain construction, combination described and particularly pointed out in the appended claims, reference being had 0 the accompanying drawings forming part of this specification, and in which:

F ig. 14 is a detail view of one of'the' clamp screws; and.

. polygonal form, as

F ig., 15is a detail view of the cross head pivot.

Referring to theidrawings it will be seen that the machine includes a frame or bed 10 supported upon suitable legs 11.

pair of horizontally spaced and alined journal frames designated at 13 and 14 are arranged upon and suitably secured to the .ed 10 at one end thereof. Rock shafts 16 and 16 are mounted for rocking movement in the journal frames 13 and 14 and, as clearly shown in Fig. 4, are vertically spaced and alined. These rock shafts are of identical construction and as shown in detail in Fig. 61the body portion 16 thereof is of polygonal shape or cross section, preferably octagonal. Adjacent each end the shaft is provided with smooth portions 16 circular in cross section and adapted to be received -n the journals of the journal frames for rotative and longitudinal sliding movement. ne end of the shaft is provided with an annular groove 16 and the other end is of indicated at 16 for a purpose to be hereinafter more fully described.

A series or plurality of dies, designated at 18, is arranged upon the upper rock shaft 16 and a coacting series of dies designated .at 19, is arranged upon the lower rock shaft up each series 16 The dies which make are identical in construction and as shown in detail in Fig. 11 consist of a body portion 20 provided with a polygonal shaped opening therethrough conforming to and snugly fitting the polygonal portion 16 of the rock shaft with which it is associated whereby the dies are constrained to partake of the motion of the shafts. The body portion 20 is provided with an outwardly extending die or bit holder 22 which is provided in its 23 to receive the die proper or bit 24. hen the dies of each ser'es are arran ed upon their rock shafts the dies proper or bits 523 are maintained in spaced relation by means of the body p0rtions 20 and are secured to the rock shaft by means of collars 25 and set screws or lock pins 25. i i

As shown in the drawings the dies of the series 18 are staggered with respect to the dies of the say, the dies of the series 18 areopposite the spaces between the dies of the series 19 and the dies of the series 19 are opposite the spaces between the dies of the series '18. The warp rods opposite bending of adjacent warp rods when they partake of oppositely swinging movement imparted to them by the rock shafts.

Means is provided for driving or rocking the rock shafts and the dies of each series in opposite directions and includes a pressure cylinder 27 closed at its ends by cylinder heads 28 and 29, respectively. The pressure cylinder 27 is supported by means of aweb 28" integrally formed with the cylinder head 28 and bolted to the bed 10. A piston 30. is slidably arranged in the pressure cylinder and is provided with a piston rod 31 extending through a suitable stuffing box 32 in the upper head 28 of the cylinder. The piston rod is pivotally connected at its upper end to the lower end of an adjustable pitman 33, as indicated at 3.4, the upper end of which is pivotally connected, as at 35, to one end of a swinging cross head 36, shown in detail in Fig. 10, which is pivotally mounted by a pivot 37, shown in detail in Fig. 15 and carried by 2. lug 38 integral with one of the journal frames. A link 39 has one end pivotally connected to the swinging cross head by means of a pin 40, shown in detail in Fig. 8, and has its opposite end pivot-ally connected, as at-41, to a rock arm 42 fixed to the upper rock shaft 16. A second link 43 is pivotally connected at one end, as at 44, to the swinging cross head and is pivotally connected at its other end, as at 45, to a sec ond rock arm 46 which is fixed to one end of the lower rock shaft 16. It is obvious that when pressure, such as steam, air or the like, is admitted to the lower side of the piston it forces the piston upwardly in the cyl inder and swings the cross head 36 about its pivot and by the action of the links and rock arms induces opposite rocking motion of the rock shafts 16 and16 In order to return the piston to its lower position in the cylinder, and to return the rock shafts to their original position the cross head is provided with a counterweight 50.

To relieve these instrumentalities of jar and shock on the return movement the piston rod 31 is provided with an integral annular collar 31 'at its upper end adapted to engage onits downward movement a coil spring 31 arranged around the piston rod,

, as shown in Fig. 5 and thus take up any 1 cs shock or jar that might occur.

they carry and consists of a shifting yoke 51 pivoted at 52 to one of the journal frames and having an upper and lower pair of pins, designated at 53 and 54, respectively, which project into the annular groove 16 on the ends of the rock shafts 16 and 16 respectively. At the upper end of the yoke there is provided a cross bolt 55 which is. selectively engageable with notches 56 formed in the latch bar 57 which is pivoted at 58 to the top of the journal frame. By means of the latch bar 57 the shifting yoke may be held in desired position.

Feeding means is provided for advancing the screen through the machine and consists of a pair of screw shafts 60and 61 journaled in bearings 62 and 63, respectively, and arranged along each of the longitudinal sides of the bed of the machine. The screw shafts 60 and 61 are driven from a common drive shaft 64 journaled in bearings 65 and drivshafts. The carriage 68 includes a clamp ingbed 69 having a contour conforming to the contour of the screen so as to receive and grip the same and a coperating'clamping bar 70 adjusted toward and away from said clamping bed by means of clamp screws 71 shown in detail in Fig. 14. The power shaft 64 which actuates the feeding mechanism may receive its power from a motor but is preferably adapted, as at 64 to be actuated by a hand crank (not shown).

Beyond the carriage 68 the screen is received and rests upon an angle screen rest 72 mounted on the bed by means of suitable supporting lugs 7 3. I

In operation when pressure is admitted to act upon the underside of the piston 30, the piston is forced upwardly in the cylinder and the swinging cross head is rotated about its pivot and through the links 39 and 43' and rock arms 42 and 46 effect an oppositely rocking movement of the rock shaft 16 and 17 so as .to swing the staggered dies of the series 18 and 19 toward and past each other.

then relieved of pressure so that .thecounterweight 40 is effective to return the piston and the rock shafts and the dies which they carry to their original position. The shifting mechanism is then actuated to shift the dies of each series so that they again engage the warp rods to repeat the bending operation and after the weft rod has been inserted this cycle of operation may be repeated. ith each operation of the dies the feeding means holds the warp rods so that they may be properly bent and with each insertion of a weft rod the feeding mechanism is actuated to advance the screen across the bed to the desired extent. For this purpose, the power shaft 64 is turned and it imparts the desired rotation to the screw shafts and 61 which cause the carriage 68 to which the screen is clamped to traverse the bed and thus advance the screen as desired.

It is to be understood that this machine is most especially adapted for use with slat members or wire me -berswhich have been previously crimped.
