1 b all whom it mog concern: v

Be it known that we, "ANTHONY RH'EN- STROM, a citizen of the UnitedjStates, re-

siding at Kenosha, inthe county of Kenosha and State of \Visconsin, and HENRY 1T Hassle, a citizen of theUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wire-Link- Fabric-Closing Machines, of which the fol lowing is a specification.

This invention relates in general to wire working machines and has more particular reference to machines for making wire fabrics such as are customarily .used for bed bottoms and on sanitary couches, davenports and the like, the present machine being designed to close the hooked ends of the links of which the fabric is composedso as to lock the links 'securely'together.

One of the primary objects of this invention is the provision of a machine which will hold a row of fabric linkswith the hooked ends in convenient position to re ceive the links of the next row to be assembled, and which will automatically close the hooksof the entire row of links and will then advance the assembled links a predetermined distance to bring the hooks of the succeedingrow into the. desired position.'

Another object of the invention, is to provide a machine which will aline and properly position the links so that the hooks will be in proper position to be operated upon ,,of the pulley 17 torotate therewith, A, disk 21 secured on'the shaft 16 by a key 22 has by the closer and uniformly closed.

Another object is to provide mechanism,-

for operating thecloser which will be positive and accurate in its operation, whic will be simplein construction and easy to manipulate so that the machine canbe operated with a minimum expenditure of power,

A further object is to provide novel mechanism for automatically advancing the assembled fabric a distance equal to the length of asingle link after each closing operation and also to provide novel means for controlling the operation of themachine.

Other objects and advantages of this invention .will be apparent as-the same becomes better understood by reference to the following description when considered Y in. connection with the accompanying drawings.

Referring to the drawings,Figure '1 is a front elevation of a machine embodying my invention; Fig. 2 isan end elevation looking toward the left at the machine shown in Fig l; Fig; Sis'an enlargedde" tail view of the mechanism for advancing Fig. 5'is a sectional view on the line '55" of Fig. 3; Fig, 6 is sectional view onthe 6 of Fig i; Fig. 7 is a transverse. sectional view'on the line. 7 7 of Fig; 1;? Fig. 8 is a sectional view taken on the line line (5 8 8 ofFigQ 9; Fig.9 is a fragmentaryseo tional view taken on the line 9 of Fig. 7

Fig. lO'is' a fragmentary transverse sectional view taken substantially niedially of the machine; Fig. 11 is a detail view showing. the position of the parts ustprior to the.

closing operation; Fig. 12 is a similar View,

showing the position of the parts at the completion ofthe closing operation; Fig.1i3' is a deta l perspective view ofone of the -link-supportingjblocks; and Fig lt is a' fragmentary view of the fabric.

0n the drawings reference character be-later described, are carried. A ma n shaft 16, journaled in-the frame, is provided at one end with a pulley 1 7. loosely mounted thereon through which power is applied to 8 and 9) provided with a plurality of indicates the main frame of the machine upon whichlthe vai'ioiis'operating parts, to

notches or depressions 19 is fixed on the hub pivotallymounted on a pin 23 projecting from its outer face a dog or clutch member, I

24-. shaped at oneend, as indicated at 25, to

engage in the notches 19 and formed at its other end toprovide a tail 26 adapted, when other form of abutment 28 projecting'from the disk,;n0rmally urges tl e dog intothe operative position shown in Fig. 8 to thereby;

lock the-pulley to the shaft 16.

A roller QScarriedon; the o ..l;ter eildy'if long tudinally movableuod or shaft 29 mounted in the main frame is normally dis; '5

posed'in radial alinem ent withthedogQso that when the shaft 16 completes a revolution the tail 26 of the dog will be depressed by the roller to disengage the opposite end of the dog from the clutch member 18, thereby permitting the pulley to run idly on the shaft. A lever 31 pivoted at is connecteo at one end with the rod 29 and at its other end with an operating rod 33 extending transversely of the machine in position tobe grasped by the operator and moved longitudinally. The rod is normally held in the position shown in Fig. 7 by an expansion spring 3st disposed between the nut 35 on the end of the rod and one of the rod-carrying brackets 36 so that the roller 28 is in position to release the clutch and maintain the same in released position. lln order to prevent accidental movement of the rod 33 we have provided a latch 38 Fig. 10), pivoted at 39 and urged into engagement avith the rod 33 by means of a contraction spring 4&1. The rod 33, as shown in Fig 7 is provided with a notch into which the latch 38 enters to thereby lock the rod against movement. The l'Ot 33 is also provided with a second notch 4E3 into which the latch 38 will fall before the clutch is released upon movement of the rod to the left (viewing Fig. 7) unless the operator holds the latch in raised position with one hand while he manipulates the rod 33 with the other. This construction insures the use of both hands of the operator in moving the roller 28 from engagement with the dog 2% and prevents accidents to the operator, such as might happen if one hand were free to be caught by the closing mechanism. By raising the latch and moving the rod 33 to the left the roller 28 is withdrawn from engagement with the dog 24, permitting the pulley 17 to'be clutched to the shaft 16. As soon as the rod 33 is released the spring 3 f returns the roller 28 into the path of the dog 2 1 which is thereupon disengaged from the clutch member 18 when the shaft completes one revolution.

A frame 44 rising substantially vertically from the main frame 15 is provided with suitable journals at its upper end in which a shaft is rotatably mounted, Sprocket wheels a6 and l? fixedly mounted on the ends of said shaft are connected by endless chains d8 and 49 with sprocket wheels 51 and 52 respectively, mounted upon stub shafts projecting laterally from the main frame. Suitable idlers 53 and 54 are mounted on the frame to engage the rear laps of the chains 48 and 4:9 for the purpose of diverting the chains away from other operating parts of the machine.

Secured to the front laps of the chains 48 and 4-9 in substantially horizontal position is a bar 55 which extends transversely across the machine and is adapted to carry a plurallty of blocks '56 slidably mounted on the bar, as shown in Fig. 13. Each block is equipped with a set screw 57 by means of which the block may be locked in adjusted position on the bar, and is also provided on its forward face near the lower end thereof with a forwardly and upwardly projecting hook 58. The links 59 of the first row are suspended from these hooks 58 with their hooked ends downwardly and the blocks are adjustable on the bar 55 in order to accommodate them to links of various widths, depending upon the style of the particular fabric to be assembled.

An. anvil comprising a rigid substantially T-shaped member 61 upon which a series of anvil blocks 62 are secured by means of bolts (30, is mounted on the frame 15 at the lower end of the upright frame 44. The anvil blocks which are preferably of hardened steel are provided on their forward or operating faces with vertically disposed corrugations which serve to prevent sliding or slipping of the links longitudinally of the anvil when they are compressed by the closer, as will be later described. hen the fabric is to be started a link 59 is suspended from each of the hooks 58 and the bar 55 is positioned to bring the open hooks 63 of the suspended links directly in front of and in proximity to the front face of the anvil. A. second row of links 64- is then suspended from the hooks 63 of the first row, as shown in Fig. 14, this second row of links being engaged with the hooks of the first .v either by hand or by suitable feeding and positioning mechanism. After the entire second row of links has been positioned upon the hooks of the first row these hooks are closed or bent fromthe position shown in full lines to the position shown in dotted linesin Fig. 14, by mechanism which will now be described.

A secondary shaft ('35 is mounted in the main frame rearwardly and above the main shaft 16 and upon this shaft is pivotally supported a pair of arms 66 carrying their forward ends a closing bar consisting of a main portion (37 and a hardened portion 68 having aninclined rear closing face 69. A plate 71 is slidably secured by bolts 72 upon the upper face of this bar and expansion springs 73 situated in suitable sockets in front of the plate 71 normally urge the plate rearwardly so that its rear edge projects over the corres 'mnding edge of the closing bar. as shown in Figs. 10, 11 and 12. Each arm 66 carries a cam follower or roller 7-1 which rests upon a corresponding cam T 5 fixed on the main. shaft 16. The cams 75 at opposite sides of the machine are identical so that the raising and lowering movements imparted to the arms (36 by the cams upon rotation of the shaft 16 are alike and both ends of the closing bar receive the same movement. The followers are held in contact with their respective cams by means of coiled contraction springs 7 6 attached at 7 7 to arms fixed on the main frame and at 78 to the arms 66. The closing bar is: normally maintained in lowered inoperative position, as shown in Fig. 2, the followers 7r resting upon the low parts of the cams 75. Betation of the cams in a counter-clockwise di rection, (viewing Figs. 2, 11 and 12) will first elevate the closing bar to the position shown in Fig. 11. Each cam 7 5 is provided on its high portion with a depression 79 which permits a slight downward movement of the closing bar so that the hooks 63 of the row of links to be closed are engaged by the projecting edge of the plate 71 and pulled downwardly a limited distance to aline all of thehcoks and place them in proper position to be closed by the inclined closing edge 69 of the closing bar.

For the purpose of imparting a rearward movement to the closing bar toward theoperating face of the stationary anvil to thereby compress the ends of thelink hooks into the closed position shown in Fig.- 12 and also in dotted lines in Fighlat we have provided mechanism which will now be described. The shaft 65 has fixedly mounted thereon a pair of cams 81 in proximity to the arms 66 adapted to coperate with fol lowers 82 in the shape of rollers mounted on the rear ends of the arms 66 to move the arms longitudinally into rearward direction. It will be apparent from an inspection of the drawings that each of the arms is provided with a longitudinally disposed slot 83 loosely embracing the shaft 65 so that the arms arecapable not only of a pivotal move ment about the shaft 65 but are also capable of a longitudinal movement transversely of the shaft. shaft 16 through the intermediary of inter: meshing gear wheels 84 and 85 of equal diameter. Each time the depressed portions 7 9 of the cams 7 5 are brought beneath the followers 7% the high portions of the cams 81 are moved intoengagement with the followers 82 to thereby. impart a rearward longitudinal movement to the arms 66, forcing the closing bar against the hooked ends of the links. During the closing movement of the closingbar the plate 71, which has previously performed the function of :alining the link books, is forced forwardly against the action of the spring 73 relatively to theclosing bar, thus permitting the closing bar to press the link hooks against the stationary anvil into closed position. Continued move- 4 ment of the cams 75 will first elevate the closing bar away from the hooks and. then permit the bar to return to its normal inoperative position shown'in Fig. 2. The arms 66 will in the meantime, after the high portions'of the cams 81 have passed the followers 82', be moved forwardly on the shaft The shaft 65 is driven from the 65 by the contraction springs 13 attached one end to fingers 14c-projecting upwardly;

from the rear ends of the arms66 -and@attached at their other ends to pins 86 fixed on the stationary .anvil. It will thus be; 'manifest that at each operation of the -clos,

ing bar the link hooks are first properly alined against the forward face of the anvil and are then compressed between the anvil and the closing barinto closed position, allof the links of therow being closed simultaneously.

Aftereach closing operation-pit is desirable to move the assembled links imwardlyi a distance equal to the length of a linkso The mechanism for advancing the assembled links a predetermined distance after each closing operation will now be de--.-"

scribed.

Referring more particularly to- Figs. 1 to 6 inclusive, it wil'l'be observed that g the hub of the sprocket wheels? has fixedly mounted thereon a ratchet wheel 87. :Adja-i.

cent to the inner face of the ratchet wheel there is loosely mounted upon the shaft 15 a ing arm 89 earrying'at its outer end pawl 90 which is malntained 1n cotlperative relation with the teeth'of'the ratchet wheel 87 i b means of a sarin 92. A salit rin fricl b l h and is held inposition on thehub by a plate 7 or disk 100. The split portion of the ring 1 91 terminates. 1n lateral extensions 93' and jhub 88 having. anintegral radially projecttion member 91 loosely embraces the hub 88 i the opposite side of the ring is provided' with an arm 9% having a longitudinally ext-f tending slot 95. A. rod 96 bifurcated at'its upper end as shown in Fig. 8 is attached-to the arm 94 by means of a pin 97 passing through the slot 95.1 The lower end of arm 96 is attached at 98. to one of' the arms 66 so that this rod will be reciprocated' longitudinally at eachoperative movement of the closing bar. A turnbuckle 99 ispreferably interposed in therod' 96 intermediate its ends by Ineansbf'which the length of the rod may be adjusted The lower one of the extensions 93 is adapte'doto receive thethreaded bolt 101 which has a: smaller unthreaded port1on'102 extending through the, upper extension 93,- and a CO1=l6Cl expansion spring 103 surrounding the portion 102-and interposed between the upper extension 93,

and a'n'ut 10-1: normally the'extensions 93 toward each other to cause a frictional engagement-between the ring 91 allClt-llG-lllll) 88. The lower end of the bolt 101'is swivel ingly connected by a link 105 to an opera-t- 1 ing rod 106 having a handle 107 'a'tfits lower end in convenient reach of the opera} tor and by means of which the bolt maybe i turned. When the machine is in operation the bolt is partially unscrewed from the lower extension .93 to permit the ring 91 to be frictionally clamped to the hub 88 by the spring 103. The arm 9-1 is thereby rigidly connected with the arm 89 carrying the pawl 90, and it will be obvious that at each oscillation of the arms 66 carrying the closing bar the shaft #15 will be given a partial rotation through the instrumentality of the pawl 90 operating upon the ratchet wheel 87. The movement of the shaft will, of course, take place during the downward or return movement of the arms 66 so that after each closing operation the sprocket wheels 46 and 4L7 will be rotated a sufficient distance to move the link-supporting bar 55 upwardly on the frame the requisite distance to position the succeeding row of link hooks in proper relation to the anvil. Another row of links is then engaged with the hooks of the second row, these hooks are then closed by the'closing bar and the assembled links are advanced another step. These operations are repeated until the entire fabric is assembled. hen the bar 55 reaches the upper end of the frame ll it strikes against an abutment 107 which precludes further feeding movement of the chains. Should the closing bar be operated again the spring 103 will permit the ring 91 to move idly on the hub 88 so that no damage to the machine can result from carelessness of the operator. It will be understood of course that after each closing operation the driving clutch will be automatically opened so that the main shaft 10 will stop in the position shown in Fig. 52, and that after the next row of links have been positioned the machine will be thrown into operation by manipulation of the controlling rod 33.

The frame 44; is strengthened and braced by a plurality of brace rods 108, and backing for the central portion of the assembled fabric is provided by slats 109 adjustably connected at their lower ends by bolts 111 (Fig. 10) to the stationary anvil, provision for adjustment being made so that the slats may be adjusted laterally to permit the requisite adjustment of adjacent link-supporting blocks 50. A brace bar 112 shaped substantially as shown in Fig. 1 is attached to the ends of the bar and maintains the rigidity thereof under the downward pull on the links of. the fabric.

After a fabric has been completely assembled by successive operations of the machine, as described, the rod 106 is turned so as to force the shoulder 127 of the bolt 101 against the upper extension 93 to thereby separate the extensions 93 against the force of the spring 103 and release the frictional engagement between the ring 91 and the 11111) 88. The shaft 45 is now free to turn and the bar 55 may be pulled down by the operator into its initlal position so that the fabric may be taken off and a new row of links may be positioned on the supporting hooks 58. The rod 106 is then turned to withdraw the shoulder 12'? from the upper extension 93 thereby reestablishing the fricfrom the foregoing without further d scription, and it should be obvious that "he details of construction which have zen shown and described for purposes of illustration are capable of considerable modifica tion without departing from the scope of the invention, as set forth in the following claims.
