The present invention is related to the camoufiage fabricating machines disclosed in the William E. Meyer application, Serial No. 447,602, filed June 18, 1942, and to the application of William E. Meyer and H. W. Collins, Serial No. 454,276, filed August 10, 1942.

According to the present invention, a camouflage fabricating machine is provided in which cords of fibrous glass are fed from spools and deposited onto a wire mesh backing member. The

fibrous glass is in the form of fiber strands, known in the trade as glass fiber sliver, roving or yarn. In certain forms of the invention, the cords of fibrous glass are deposited between upper and lower layers of wire mesh and such wire mesh is then secured together through the fibrous glass. The wire mesh backing member, in the embodiments illustrated, is in the form of ordinary chicken wire. which is bonderized prior to the application of the glass wool thereto. After the fibrous glass is secured to the wire mesh, it is coiled into rolls and thereafter subjected to a dip painting process. The present machine is primarily concerned with the application of the fibrous glass to the wire mesh and securing of it thereto.

The cords of glass fibers are threaded through the cords are blown through the blow-heads and deposited onto the mesh.

Referring to the drawings for a better understanding of the invention, and referring particularly to Figures 1 through 5, in which one embodiment is illustrated, an elongated table support is generally indicated at II and a mounting frame, generally indicated at I2, is disposed adjacent one end of the table support I. A roll of wire mesh 14 is rotatably mounted on a transverse shaft II, which is supported in suitable bearings mounted on the frame I! in the lower portion thereof. Such wire mesh in the embodiment illustrated is in the form of ordinary chicken wire.

A table support I6, having an upwardly inclined top surface, is disposed between the frame I2 and the table I and is adapted to receive on the upper surface thereof the wire mesh I4. Another roll of wire mesh I1 is rotatably mounted on a shaft l8, the ends of which are pivotally received within hearings to bearing brackets l9 which are se cured to the table support I6. The wire mesh I1 is disposed above the wire mesh I4, and cords of glass fibers are deposited onto the top surface of the mesh I4; and the mesh I1 is thereafter laid on top of the fibrous glass, so that such glass is sandwiched therebetween.

The means for depositing and distributing the cords of glass fibers are mounted on the frame I2 above the roll I4. Such cords of glass fibers are indicated at 20 and are wound on spools 22. A plurality of such spools 22 is rotatably mounted on spindles 24 at spaced intervals across the frame I2 and at the rear thereof. Such spindles 24 may be received within mounting brackets 25, which are fixed to a transverse frame member 28.

Each of the cords 20 is passed through a pigtail guide-eye 21 (Fig. 3), which depend from the top transverse bar of the frame I 2. Each cord is then wound about a feed drum 28 and is then passed through another pigtail guide-eye 29, which is mounted on the frame l2.

The feed drum 21 has end trunnions 30, which are pivotally received within suitable bearings mounted on the frame l2, and one of such trunnions has a drive pulley 3| keyed thereto. The pulley 3| is driven by suitable means, such as an electric motor 32, a speed reducer, not shown, and a belt 33. The feed drum 28 serves to facilitate unwinding of the cords 20 from the spools 22 and feed such cords to blowheads I60.

The construction of such blow-heads I60 is shown in detail in Figure 9, and it'will there be seen that the blow-heads are each formed of separable sections I62 and I64. The sections provide an inner air chamber I66 which communicates with a conical chamber I68 directed to the outlet side of the blow-heads. The section I62 is provided with a central aperture I into which extends an inlet aperture I12 formed in the section I64. Each of such cords is threaded through the apertures I12 and I10 of the blow-heads I60. Air under pressure, from a suitable source, is introduced through a flexible conduit I14 into the chamber I66 through a port I16 and passes into the conical passageway I68 and out through the aperture I10. It will be appreciated that as the air passes through the chamber I68 and out through the aperture I10, it envelopes the cord 20 and pulls it through the blow-head and prejects it forwardly thereof.

The blow-heads I60 are disposed atfintervals transversely of the mesh I4, and are adapted to be moved transversely thereof. Each of the blowheads I60 is pivotally mounted to a bracket I16 by means of a U-shaped clamp I16 (Fig. 6) which embraces the end of the L-shaped tube l19 connecting the blow-head I60 with the flexible tube I14. The clamp may be pivotally connected to the member I16 by means of a bolt which passes through the ends of the clamp and the upper end of bracket I16, and clamped by a nut on the bolt which, in turn, is fixed to a transversely extending mounting bar I11. The mounting bar I 11 is slidably disposed on a transversely extending bar I18, which is mounted on frame l2. Guides may be provided on the bar I18 so as to prevent displacement of the reciprocating bar I11 with respect to the supporting bar I18.

The bar I11. carrying the blow-heads I60. is

adapted to be reciprocated transversely of the mesh I4 during the depositing of the cords 20 thereon. Suitable means are provided for reciprocating the member I11 and, in the embodiment illustrated, such means include a connecting link I18" which has one end pivotally connected to one end of the bar I11 and the other end pivotally connected to a crank disc I80. Such crank disc is keyed to a drive shaft I82, which is pivotally mounted on a frame I84. The shaft I82 may be driven through a suitable electric motor I84, gear reduction mechanism I85, and belt I86, which is connected to a pulley on the shaft I82. As the crank disc I80 is rotated, it will be appreciated that the blow-heads I60 are reciprocated transversely of the mesh I4.

Rotation of the feed drum 2B draws the cords 20 from the spools 22 and feeds them to the blowheads I60. It has been found that the use of the feed drum 28 reduces breakage in the cords to a minimum and provides for a fast feed. The air passing through the blow-heads projects the cords 20 above the inclined surface of the table I6 and onto the mesh I4. Thereafter, the mesh I1 is deposited on top of the cords 20. The upper and lower meshesof wire with the glass fiber cords therebetween are then passed through feed rolls 34, one of which is driven by suitable means, such as a motor 35, gear reduction 36, and belt and pulley arrangement 31.

After the camouflage, including the lower mesh I4 and upper mesh I1 with the fibrous glass therebetween, leaves the feed rollers on table I8, such camouflage is disposed on the support III. The upper and lower meshes I1 and I4 are there secured together and the camouflage is passed along 40 the table, where it is received by a coiling means and coiled into rolls. The structure from the time that the camouflage leaves the table I6 is substantially the same as that disclosed and claimed in the Meyer application, Serial No. 447,602, above referred to.

The strips of camouflage leave the table I6 and drop downwardly between the table I6 and the support I0, and are continuously fed to such space by the drive rolls 34. The camouflage is intermittently moved along the table I0 and the sagging of the camouflage within the space permits such intermittent movement along the support. In order to maintain proper tension in the camouflage and to insure its lying against the support I0, a pipe or rod 38 is disposed in the trough of the sag in the camouflage. It will be appreciated that such rod 38 rides in the trough as the strips are intermittently fed along the table III. The meshes I4 and I1, with the fibrous glass therebetween, are fed along the table I0 by means of a reciprocating clamp, generally indicated at 40. Such reciprocating feed clamp 40 is best shown in Figures 4 and 5. The feed 40 comprises a reciprocating frame having side members 42 connected together by transverse members 44 and 46. The members 44 and 46 are disposed above the table I0 and rollers 48 are pivotally mounted to the side members 42 and are adapted to roll along trackways 50 mounted on the table I0 longitudinally thereof.

The reciprocating frame 42 carries a clamp which includes the transverse member 46 forming the underside of the clamp, and an upper transverse member 62. The member 46 has a pair of transversely extending, continuous projections 64 formed on the upper surface thereof. and the upper member 62 has threedepending similar projections 66 formed thereon. Projections l4 and 66 are so disposed with respect to each other that the projections 64 are adapted to be received between the adjacent projections 66. when the members 46 and 62 are in clamping position, the projections assume the position shown in Figure 5 so that the strips 22 and mesh I4 are clamped therebetween with such firmness that the strips and mesh may be moved along the tabl I0 as the carriage is moved in one direction. The edges of the projections 64 and 66 are round, and such projections are continuous so that they do not catch on the wire mesh or the glass fibers as the clamping elements are moved with respect thereto.

The upper member 62 has a transverse member 68 secured to the top surface thereof, and such members 62 and 68 are secured at their ends to pivot arms 60. Such pivot arms 60 are disposed at the sides of the table I0 and are pivotally connected to the side members 42 of the reciprocating frame through upstanding brackets 62 and pivot pins 64.

- The leading ends of the arms 80 are so shaped that they lie substantially horizontal when the members 46 and 62 are in their clamping position. The arms 60 are pivoted about the pivot pins 64 in order to move the members 46 and 52 to clamping and releasing positions by means of'an air cylinder 66. Such air cylinder 66 is mounted to a frame having side members 68 connected by a transverse member 10. The side members 68 are secured to the side members 42 of the reciprocating carriage so that the mounting frame for the cylinder 66 reciprocates with such carriage. The upper end of the air cylinder 86 is pivotallyconnected to the member substantially midway between the ends thereof by means of a pivot pin 12. A piston rod 14 projects through the cap end of the cylinder 66 and is pivotally connected to a mounting plate l6,'which is secured to the members 62 and 69 substantially midway between the ends thereof. Air ports are provided in the upper and lower ends of the cylinder 66 on opposite sides of the piston, in the usual way, for reciprocating the piston rod I4 to raise and lower the clamping member 52.

An air conduit communicates with the lower port, and an air conduit communicates with the upper air port. Such conduits I8 are mounted to one of the frame members 66 and have flexible conduits 82 and 84 connected thereto through suitable connectors.

The conduits 82 and 84 communicate with the opposite ends of aconventional air reversing valve 86, which is mounted upon a frame member 88 of the table I0 under the reciprocating feed carriage. An inlet port is provided in the valve 86 in the usual way, and an air conduit 90 communicates with such inlet port and also communicates with a suitable source of air pressur (not shown). The valve is reversed by an upstanding finger or lever 92, which is disposed in the path of a pair of depending reversing fingers 94 and 96, which are mounted on one of the side members 42 of the reciprocating feed carriage.

It will thus be appreciated that as the feed carriage moves in one direction. the finger 94 shifts the valve through the operating arm 92 to admit air under pressure to the conduit 82. When air under pressure enters conduit 82, it passes through the lower port in cylinder 66 to raise the piston rod 14 and to move the clamping member 62 to its releasing position. When the carriage moves in the opposite direction, the finger 96 engages the member 92 to shift the valve to admit fluid under pressure to the conduit 84, which passes into the upper port in cylinder 66 to move the clamp-downwardly to its clamping position.

The feed carriage is reciprocated through connecting arms I0 I disposed adjacent the side frame members 42 and pivotally connected thereto by means of pivot pins I02. The opposit ends of such arms are pivotally connected to a crank arm I04 through pivot pins I06. The crank-arms I04 are keyed to a transverse shaft I08, which is mounted within suitable hearings on the frame member 88. A drive gear II0 is geared to such shaft I08. The drive gear H0 is driven by a suitable electric motor II2 through a variable speed reducer II4, having a drive gear II6 associated therewith. Such drive gear I I6 drives the gear IIO through a chain drive H8.

It will thus be appreciated that as the gear H0 is driven, the crank arms I04 are caused to rotate and, through the connecting arms IN, the carriage is caused to reciprocate. The fingers 94 and 96 are, of course, positioned on the reciprocating frame, so that they engage the shifting lever 92 at the ends of the stroke of the feed carriage. When the reciprocating carriage reaches the end of the stroke, to the left, viewing Figure 4, the clamp 52 is moved downwardly to its clamping position. The carriagethen moves toward the right, viewing Figure 4, to pull the mesh I4 and strips 22 therealong. When the carriage reaches the end of its stroke in that direction, the valve 86 is reversed to move the clamp 62 upwardly to its releasing position. The carriage is then returned to the left, with the clamp 52 in such releasing position, until it reaches the end of its stroke in that direction, when the cycle is repeated.

Prior to the engagement of the mesh and fibrous glass by the reciprocating feed clamp, the upper and lower meshes I1 and I4 are secured together by a stapling mechanism, generally indicated at I20. Such securing or stapling means is substantially the same as that disclosed in the Meyer application, above referred to, and reference' may be had to such application for a complete and detailed description of such structure.

The stapling mechanism I20 includes a framework comprising upstanding side members I22, which are connected together by cross members I24 secured thereto above the table I0. The securing means includes a plurality of conventional stapling mechanisms I26 having the usual feed magazine pivoted adjacent the rear end onto a cross plate I 28, which extends transversely of the table and is mounted to frame members in spaced relation to the upper surface of the table so that the camouflage passes thereunder. Thestapling members handle the usual U-shaped staples, which are fed out of the leading ends of the pivoted arms of the stapling mechanism so that as such arms strike a cooperating transverse die the staples are emitted from the magazines and clamped around the overlying strands of the wire mesh. There are sufficient of such arms I26 at spaced intervals across the camouflage that sufllcient of such staples will engage the wire mesh to provide a satisfactory securing of the meshes together.

The pivoted arms I 26 oi the stapling mechanisms are connected in groups to transverse bars.

Each of such bars is connected to the depending piston rods 536 of air cylinders I38. The connections between the bars I34 and the arms I24 are such that the arms I26 are first moved downwardly into engagement with the transverse die, and then further downward movement of the bars I34 emits the stapling clips and clamps them about the strands of wire mesh. This is the usual operation of the conventional stapling mechanism.

The cylinders I38 have the usual air ports on opposite sides of the piston, and are: provided with the usual conduits leading to a common reversing valve. Such valve may be similar to the valve 88, and has an air pressure port leading to a suitable source of air pressure. The operating lever for the valve, in the embodiment illustrated, is hand operated; and such valve is operated to effect the stapling operation at the time that the clamp of the feed carriage is in its releasing position, so that the wire mesh is stationary on the table.

The camouflage leaves the table I and is received by a coiling mechanism, generally indicated at I 40. Such coiling mechanism I40 includes a mounting frame adapted to have a coiling shaft I4I removably mounted thereon. The camouflage is received on the coiling means by guide bars I42, and the leading end thereof is wrapped around the shaft MI. The shaft I is, of course, rotated to coil a predetermined amount of camouflage thereon, and during the period of rotation the camouflage is continuously wound. However, it is intermittently fed to the coiling mechanism, and the camouflage sags in the space between the table III and the coiling frame.

The shaft I4I, when it is positioned on the frame, is operatively connected to a drive gear, which is driven by an electric motor I43 through avariable speed reducer I44 and through a chain drive I45.

In order to control the coiling on the shaft I, in accordance with the feed to the coiling machine, a rod or pipe I46 is disposed in the trough of the sagging portion of the camouflage between the table I0 and the coiling mechanism I46. As the camouflage is intermittently fed to this space, the trough will, of course, move up and down.

The rod 14% serves to keep the camouflage in a proper taut condition and also to control the operation of the motor I43. To control such opernausea along the table. The camouflage thin passes between such bars and the upper surface of the table II, and such bars serve to flatten or smooth out the fibrous glass prior to the various operations, such as the stapling operation.

Referring to Figs. 6 and '7, a modified arrangement of the spools 22 with respect to the feeding drum, for the purpose of feeding the cords 20 to the blowheads IE0, is illustrated. In this embodiment of the invention, the spools 22 are so mounted that the peripheries of such spools lie against the peripheral surface of the feed roll 24. The spools 22 are mounted upon the spindles 24 and the ends of such spindles are pivotally connected to pivot arms 202. The opposite ends of such pivot arms 202 are pivotally connected to mounting brackets 204 which are flxed to the frame I2. The mounting arms and mounting brackets are so arranged that the axes of the spools 22 extend in the same direction as the axis of the drum 28. The pivoted arms will permit the rolls 22 to drop by gravity against the surface of the drum 28.

The cords 20 are threaded through pigtail eyes formed on the ends of guide brackets 206 which are fixed to the top transverse member of the frame I2.

While gravity is relied upon to urge the spools 22 against the periphery of the rotating drum 24,

it will he understood that if desirable springs may be employed.

As the drum 28 is rotated, its engagement with the spools 22 causes their rotation so as to provide an ample feed of the cords 20 to the blowheads I60. It has been found in practice that this embodiment of the invention provides a very fast feed for the cords.

I of an upstanding frame I54 adjacent one end of the table it. The cords 20 unwind from the spools and are passed through guide eyes Iii which are mounted on an upstanding end of the ation, a pair of pivot arms I4! is pivotally connected to the rod I46 at opposite ends thereof;

and the opposite ends of the arms I41 are pivot-' ally connected by pivot pins I48 to depending brackets secured to the coiling frame.

A conventional mercury switch I49 is fixed to one of the arms I41 and is connected to the motor I43 through suitable electric conduits. The switch I49 is of such a construction that when the rod "6 moves upwardly and pivots the arms I47 upwardly and when the arms reach a predetermined position, the switch I49 is tilted to cut off the motor I43. When the intermittent feed is such that the camouflage sags downwardly to a predetermined point, the arms I" drop downwardly and the switch I49 is tilted to make the circuit and operate the motor I43 to cause rotation of shaft I to coil the camouflage. when a predetermined amount of camouflage has been coiled, the camouflage is cut transversely thereof, by scissors, in the space between the guide rods I42 and the coiling shaft I4I.

Suitable flattening or ironing rolls may be disposed on top of the camouflage at suitable places along the table, so as to iron it out as it passes bracket Hill which is mounted on the frame I54 for each of the spools. Each of the cords is then passed through one of the blow-heads I80.

The blow-heads are disposed at intervals transversely of the mesh I4 and are adapted to be moved transversely thereof as in the embodiments described above. Each of such blow-heads is pivotally mounted to a bracket I16 which in turn is fixed to a transverse mounting frame Ill. The transverse frame I18 is slidably disposed on supporting bars I which are mounted on a suitable transverse frame support I82.

The frame I18, carrying the blow-heads I", is adapted to be reciprocated transversely of the mesh I4. Means similar to those disclosed above may be used for such reciprocation or other means, such as those here particularly illustrated, may be used. The means illustrated here include an upstanding lever I84, the upper end of which projects between bars I86 on the frame I'll. Thus, rocking movement of the lever I84 causes the frame I18 to reciprocate transversely of the mesh. The lower end of the lever I84 is pivotally connected by a pivot pin I88 to a frame I". The lower end of such lever I84 is forked, as indicated at I92, and the forked end receives between the fingers thereof the pivotal edge of a camwheel I. The cam wheel I94 is keyed to a shaft I98 which is mounted within suitable bearings, and such shaft I may be driven through a conventional speed reducer I" by motor 200.

' As the cords are blown from the reciprocated blow-heads I80, it will be appreciated that such cords are deposited on the mesh in an irregular and overlapping fashion, as in the embodiments above described.

After the cords have been deposited on the mesh ll, they are secured thereto by hand by transversely extending wires 20!. Such wires 202' are applied by a longitudinally curved transversely fiat needle 2. The wires III! are of predetermined length, extending to the width of the camouflaged strip and one end of each of the wires is attached to a needle 204'. By moving the needle transversely of the camouflage and moving the point up and down, the wire will thread above the fibrous glass and under the wire mesh. The ends of the wire are then twisted about the edges of the wire mesh so that such wires are held in position. The wire, of course, may be applied at suitable intervals along the camouflage.

From an understanding of the above described invention it will be appreciated that the various embodiments of the present invention provide apparatus for quickly producing camouflage in large quantities.
