UNITED STATES CHARLES T. RIPLEY,4 0F CHICAGO, ILLINOIS.
APPARATUS` FOB MANUFACTURING RESILIENT PACKING 0R FILLING MATERIAL. A
Application tiled-July 11,
To all whomt may concern:
Be it known that I, CHARLES T. RIPLEY, a citizen of the UnitedStates, residin at Chica o, in the county of Cook and tate of Illinois, have invented certain`new and useful Improvements in Apparatus .for Manufacturing Resilient Packing or Flllrng Material, of which the following is a specification.
My invention relates to apparatus .for manufacturing a resilient packlng or filling l material by inserting coiled spring elements (during a given period of time.
into a body of thread-like or fibrous or like material so that the resiliency of said mate-y rial will be increased and made permanent.
One of the objects of the invention 1s to provide a machine which will expeditiously and economically manufacture a resllient roduct. of the character disclosed in my nited States LettersPatent No. 1,298,794, issued April l, 1919. ""-It will be obvious, however, that the lproduct manufactured in accordance with this invention may be varied as to the number of springs used or as to the character of the material in which the prings are embedded, so as to be suitable for various different purposes.
It is desirable that a product of the above character contain a uniform number of sprin coils for each pound of the fibrous or threa -like material passing through the machine so that the resilient quality of a batch will be uniform throughout. It is also desirable that the machineV for inserting the spring coils be capable of operating at- `a relatively high rate of speed so as to produce the maximum amount of the product I obtain the above results by providing a machine having suitable devices which coperate withv eachA other to rst Vform the coiled spring elements from wire and then automatically insert them into the material while maintaining asubstantially uniform feed of the material through the machine at the place Where the coiled springs are inserted into said material.
The coiled spring elements are inserted into the body of the material so that for all intents and purposes they are permanently united Vwith the material. This object is attained by inserting them by a screwing action so that they are interwoven with the thread-like material instead of being merely mixed with it.
One of the Specific objects of the invention Specication of Letters Patent.
Patented Nov. 1, 1921.
1919. serial No. 310,086.
is to provide a machine of the above character having a novel spring forming device consisting of one or morevunits with which the spring elements are formed and to provide coperating mechanism for preventing .any substantial relative movement between the thread-like material and the Spring forming device during the period in which the spring elements are being inserted into the material.
The invention has for further objects, the novel arrangements, constructions and combinations ofV parts and devices' hereinafter described and claimed for carrying out the above stated objects and such other objects swill appear from the following descripion.
The invention is illustrated in a preferred embodiment in the accompanying drawings wherein:
Figure 1 is a view in perspective of a machine constructed in accordance with my 1nvent1on.

YLike characters of reference designate like parts.
Referring to the drawings, the `machine of my invention consists of a frame made up of, preferably, angular side strips 15,16 and 17 vsecured together by cross braces 18 and 19. The frame is mounted on a plurality of casters 20 so that the machine as a whole may be readily moved from one place to another. This' portable feature is particularly desirable when the machine is employed in connection with the manufacture of journal box packing, as the machine may be moved to a suitable position to receive the cotton or wool waste as it is discharged from the usual waste puller, (not shown) or moved away from the same when it is desired to fill an order for a product in which `the spring elements of myinvention are not embedded in the waste. When kthe waste or' other thread-like material 21 is discharged from the Waste puller it is received (at the rightpof Fig. 1) by an endless flexible conveyer which carries the material to the opi. posite, or discharge, end of the machine.
The conveyer preferably consists of a plurality of slats 22 secured to flexible belts 23, 24 which extend over positively driven pulleys 25--25 and 26, secured to shafts 27-27 at opposite ends of the frame. The pulleys 25-25 are preferably formed' with flanges 28 which prevent any appreciable lateral movement of the conveyer. In the drawings, I have shown the upper surface of the slats 22 inclined toward the rear edge so as to4 provide a saw tooth construction which will take hold of the layer of relatively light material 21 and insure its proper movement toward the discharge end of the machine. The lower strand of the conveyer is preferably supported at suitable points by rollers 29 which are journalcd in hangers 30-30 depending from the frame members 15, 16. The conveyer is driven .with an intermittent movement toward the left of Fig. 1 by means of a variable speed motor 31 having an operative connection with the pulley shafts v2727 through a. train of gears consisting of a pinion 32, on the motor shaft 33, meshing with a gear 34 on a compound shaft 35. This shaft also has a pinion 36 fixed thereon .which meshes with a gearv37 on a main driving shaft 38. The main driving shaft 38 carries a segment gear 39 (Figs. 1, 2, 3, and 7 which meshes with a pinion 40 on a counter shaft 41, which, in turn, carries sprockets 42-43 connected with sprockets 44, 45 respectively, on the shafts 27-27 by means'of chains 46, 47. In order to obtain the desired intermittent movement of the conveyer, I have employed `the continuously driven segmental gear 39, but this is for the purpose of con- -venience only, and I therefore wish it to be understood that any suitable clutch or gear mechanism for effecting a make or break connection between the continuously driven shaft 38 and -theintermittently driven counter shaft 41 may be used instead of the segmental gear 39 without departing from the principle of my invention.
i During the period that the conveyer is at rest, a plurality of coiled wire springs 48 are formed and embedded with a screwing action in the body of material 21. The said sprmgs are preferabl formed by forcing wires 49 through dies 1n a die block 50. The die block may be provided with any desired number of dies. In the drawings I have shown ten of such dies which are preferably formed, in each case, by inserting a hard metal bushing 51 into a bore 52Xof the die block as shown in detail in Fig. 10. 'The bushing is formed with a spiral internal groove 53 corresponding to the desired pitch of the spring 48. A center core element 54 is fixed 1n the bushing so as to close the open side of the groove 53. The upper end of the core 54 extends through a die block support 55 and is threaded to receive a nut 56 with .which the die block is tightly clamped to the under face of the support 55. A washer 57 is interposed between the nut 56 and support 55 and is formed with a counter-bore 58 which is connected, by means of a flexible tube 59 to a tank 59aL containing a suitable lubricant. When the wire is being forced through the die, the lubricant is fed into the spiral groove 53 through a duct 60 in the support, connecting the counter-bore 58 with the upper end of the spiral groove.
The wires 49 from which the coiled springs 48 are made are wound on reels 6l supported in brackets 62 -securedto a rack 63. Each of the reels is provided with a central bore 64 which is somewhat larger thanthe bracket shaft 65 so that the wire, being unwound from the top of the reel, will be pulled against the weight of the reel. With this arrangement the wire is maintained suiliciently taut to prevent buckling. The strands of wire pass under guiding sheaves 66 arranged in line with feed rollers 67, 68 which force the wire through the' spiral groove 53; the wire entering the groove through a hole 69 in the die block and passing out at ,the lower end 70 of the roove. In order to avoid the possibility ofg the wires accidentally slipping off the feed roll 67, I preferably provide a guide duct 71 adjacent each of the rolls to hold the `wire in proper position. The pressure, of
`shaft 73. A bearing block v76 is slidably fitted in the upper end of the yoke and `fits over the upper portion of the upper shaft 74. A cap 77 is secured to the upper ends of the yoke and an adjusting screw 77 extends through the cap and bears against the to of the bearing block 76. The upper feed s aft 74 and the lower shaft are driven intermittently to feed the wire into the die. This operation is performed by means of a segmental gear 78 secured to the outer end of the continuousl driven main shaft 38, previously describe The teeth of the segment 78 mesh with a pinion 79 on the feed-.shaft 73 and are arranged on the opposite side of the gear 78 with relation to the position of the teeth of the segment 39, providing the intermittent driving connection for the conveyer, so that the s rings 48 will be formed and inserted into t e body of material while the conveyer is at rest. As soon as the springs 48 are entirely inserted in the material the wires are severed at the discharge opening 70 of the dies by means of cutters 80` These cutters are preferably of hardened metal and are operat1vely supported in slots 81 formed 1n the bottom of the die block 50. In the drawlngs I have shown the cutter secured to a cutter bar 82 which is longitudinally movable in side bearings 83 of the die block support 55.
tween a shoulder 85 on the cutter bar 82 and j one of the bearings 83. The cutting operation is effected by means of a cam lug 86 which is secured tothe inner face of the gear 37 and adapted to engage one end of the bar 82. The spring 84 is ordinarily sufficient to return the cutter bar to its inoperative position but in order to insure this action the gear 78 is provided with a similar cam lug 86 adapted to engage the opposite end of the cutter bar. The position of the cutter bar may be adjusted by means of a plug 87 (Fig. 4) which is screwed into the end of the bar 82 adjacent the gear 37. The cutters, die block and feed roller shafts, as it will be seen in the drawings, are all secured to the die block support and this support is preferably hlnged as indicated at 88 to upstanding bearing elements 89 secured to opposite sides of the frame of the machine. With this construction the die block and support may be raised So that the under Side of the die block 50 may -be readily inspected or other associated parts adjusted without removing the wire from the dies.
In order to prevent the material 21 being entangled with the cutter blades 8O and other operating parts of the spring forming device, I provide a sheet metal guard plate 90 which is preferably secured to the bearing members strand of the conveyer is held in an elevated position as shown in Fig. 7, so that the ma terial will be (pressed against the under side of the guar plate 90. This operation is accomplished b means of eccentrics 92--92 secured to a s aft 93. This shaft carries a pinion 94 which meshes with the gear 40 which, as previously described, meshes intermittently with the sector gear 39. As soon as the springs are inserted the eccentrics are moved to lower the conveyer and a forward movement is imparted to the conveyer. The rapid raising and lowering of the conveyer together with the intermittent forward movement operate to maintain a sub -stantially uniform distribution of the material at the inserted.
. In the drawings, I have shown side boards 941-94a supported a 'short distance above the conveyer by brackets 95 which are bolted to the frame as indicated at 96. The brackets are preferably provided with a plurality of bolt holes 97 so as to permit the boards to be adjusted as desired. Under certain conditions it is desirable to use less than the entire number of spring forming dies, in such event the side boards 94, 94 may be adjusted to direct the material under the die being used. 98 designates a rheostalt or transformer for controlling the operation of the variable speed motor 31.
While -I have described my invention in connection with certain specific constructions it will be obvious that modifications in the arrangement, constructions and operation of the various parts may be made without departure from the spirit of my invention. I, therefore, do not wish to be limited to the specific structure shown and described except in so far as specific limitations may appear in the appended claims.
