`vFILLING MACHINE.

Application filed.` March 21, 1921. Serial No. 454,093.

T all whom it 4may concern.'

Be 1t known that 1, HARRr A. SHIELDs, a

' citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Filling Machines, of which the following is a specification, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form a part of this specification.

This invention relates to improvements in machines for filling containers with springs, and more particularly for filling fabric pockets with springs under tension, and with holding the pocket 'containing the compressed or snubbed spring during the operation of closing or sewing the open or free end of the pocket; such spring contained pockets being of the'character illustrated and described in the patent to James Marshall, No. 685,160, dated October' 22, 1901.

The principal object of my invention is to improve upon the type of machine described and claimed in Letters Patent of the United States No. 1,370,533, dated and issued on the 8th day of March, 1921, to Fredrick C. Genge, and to which reference is hereby made.

The present invention improves upon the type of machine referred to, in various details and consists in the devices and combination of devices herein illustrated and described and more particularly pointed out in the appended claims.

The machine, in general terms, comprises a plurality of tubular receptacles, into which springs are placed. These tubular receptacles areI generally arranged side by side in a series, in the sameplane. Over one end of each of these receptacles are placed a `series `ot' flexible pockets or cotton cloth or similar fabric, one end of each pocket being closed. The springs are then forced from the receptacles into the pockets and snubbed or compressed therein, the close-d end of the pocket resting against a suitable abutment in what is called a holder. The Yholder is removable and is so arranged as to retain the springs under compression within the several pockets, until the open or receiving ends of the pockets are suitably closed, when the spring contained pockets are removed and the operation is repeated.

The nature of the invention will be more fully comprehended from the accompanying drawings and subjoined description thereof.

Fig. 19 is a diagrammatic View, taken in the plane of the line III-III of Fig. 3, showing the plunger' in one of the tubular receptacles, with the hinged part of the latter closed down.

A standard or framejof any convenient construction may be used. In this instance, I illustrate in the drawings, a pair of front uprights or supports 1, 1, and a similar pair of rear supports 2, 2. The front and rear supports are joined by transverse brace bars or tubes, 3, 3, secured in brackets 4, 4. At the top, each front and rear support 1 and 2, on each end of the frame, support and are secured to a side plate or member', 5. The two front supports 11 are joined together by a brace rod or tubular member 6, supported on brackets or bearings 7, while the two rear supports 2, 2, are similarly joined by a brace or tubular bar 8, secured in brackets 9, 9. Preferably, the bars 6 and 8 are higher from the floor or other point of support, than are the brace rods or bars Any suitable power to drive the machine may be used. In the drawing, the power is indicated as a whole, by the letter- P, applied to the pulleys mounted on the shaft 10, one end of which shaft may be supported in`a suitable journal 11, upon one of the cross bars 3. Attached to one of the side plates 5 and supported upon a shaft 12, is a suitable power transmitting device, including a clutch mechanism. This device is indicated as a whole by the letter B, and it 4 is adapted to be actuated from the power transmitting device I), by any suitable means. One end of this shaft 12 is mounted in the bracket 13, secured to the side plate The details of the power transmitting means and of the clutch mechanism form no specific part of the invention, are not illustrated, and need not be described, since any well known power transmitting and clutch reversing mechanism may be used. The clutch operating mechanism may be actuated in any suitable manner from a shaft 14, suitably supported at one end in a bracket 15 mounted upon the frame.

At the forward endof each of the side plate members 5 is a bracket 16, adjustably secured by a bolt 18 passing through the slot 19. These brackets 16 provide at their outer ends, journal bearings 20 for supporting the shaft 21, which latter extends across the front of the machine from one side plate 5 to the other. Hingedly supported upon the shaft 21 is a table 22, provided foot or operating treadle- 28, the arms 29 of which extend over and fulcrum upon the shaft 27. To the rearward end of one of `the arms 29, the lower end of the rod 25 is secured. 30 is a spring surrounding the lower end of ythe arm 25. The spring is held by a pin 31 against upward movement upon the arm 25. 32 is a plate provided with forwardly projecting arms 33, 33, by which the plate 32 is pivotally mounted upon the shaft 27. 34 is an adjusting bolt on the plate 32, one end depending below theplate 32 and in juxtaposition to bear against the top surface of the arm 29 of the treadle 28. When foot pressure is applied' to the treadle 28, the spring 30 is first compressed, and then the rod 25 moved upwardly and as the treadle 28 continues to rock about the shaft 27, one of its arms 29 strikes the bolt 34 and carries the plate 32 upwardly with a rocking movement about the shaft 27. The plate 32 is also a foot treadle and has a rearwardly extending arm 35, to the4 outer end of which a connecting rod 36 is joined, the upper end of this connecting rod being suitably connected to a crank arm 37 on the operating shaft 13.

Upon the top of the frame; at the rear thereof, and joining the two side plates 5, 5, is a flat table indicated by the letter T. This is preferably made of wood, as indicated.` Between the forward margin of this table T and the transverse shaft 21, are a.

pair of supporting and connecting bars 38, 38, the same being preferably of channel iron. These extend from one side plate 5 to the other. Upon these supporting bars 38 is mounted a plurality of pocket filling cylinders, of peculiar construction, and designated as a whole by the letter C. These cylinders, preferably of sheet metal, are placed side'by side,y and the group extends from one side plate 5 to the other. The springs S are fed into the cylinders and moved longitudinally therethrough by pistons orplungers 39. The forward end of the tube C is provided with a hinged cover 40 having an inclined upper surface. This cover is so constructed that when closed, as shown in Fig. 3, the forward end of the tube C is substantially closed and is of such cross-sectional area as to permit the open ended fabric pocket F to be readily placed thereover. Whenl the plunger 39 is being actuated in its forward movement, to press the spring S through the tube C, the forward end of said moving spring readily raises the hinged cover 40 into the position shown in Fig. 4, thus distending the open mouth of the fabric pockets and holding the pocket upon the cylinder by frictional contact, the pocket being then in tubular form, ready, to receive the spring S.

In the rear of the tubes C', I place a. spring feeding table, indicated as a whole by the letter D, the same cons isting of a plurality of U-shaped troughs, one for each cylinder, the shapeof each being clearly shown in Fig. 17. The end trough of the series is. provided with an L-shaped bracket support 41, by which said feed table D may be sup ported upon the side plates 5, It will be noted by reference to Figs. 3 and 4 th-at the work receiving table T has a horizoi'ital'surface, while the surface o-f the feed table D is inclined forwardly and downwardly. The springs S are brought in quantities to the table T. The operator then places the springs inthe grooves or recesses of the inclined feed table D, where the end of each spring will rest against a back stop 42.

VVhenthe plunger 39 is in operation` as indicated in Fig. 3, the springs S are pre vented from sliding down from the feed table D into 'the tube C, by the back stop 42, which is mounted on the swinging top E, the cross sectional shape of which tubes C are indicated in the view, Fig. 18. The top E consists in a plurality of sheet metal members hinged attheir forward ends, at 43. 43, to the tube (l, and all joined at their forward ends by the L-shaped transverse bar 44. When the tops E are in `their lowerposition, asindicated in Fig. 3, they complete the tubes. (l and form substantially a cylinderthrough which the springs S and the plungers 39 move. This is more particularly indicated in Figs. 3 and 19. It will be understood that the tops E. being connected to the bar 44, will all move in unison. This movement may be accomplished by the following means:

O n each of the side plates 5 is a bearing 45 fora stub shaft or pin 4?.l On each pin 46 is mounted a lifting arm 47. The longer end of the arn; 47 is provided with a shoulder or bearing flange 48. resting in contact with the under surfacev of .the L-shaped transverse bar 44. It will be noticed by Figs. 6 and 7 that when the short arm 49 is in its fo-rward position, the flange 48 on the longer arm is in, its lowest position. thus permitting the top E to swing downwardly by gravity into the position shown in Figs. 4, 6 and 19. In this position` the stop 42 -closes off the forward end of the complemental grooves or spring-holding runways in the receiving table D. thus preventing the springs from slipping-off the table D intothe tube Q. lt will also be noticed that when the short arm 49 is in its rear position, n asindicated in Fig. 7, the swinging top E is raised, as clearly shown in Figs. 3 and 7, thus permitting the springs S toA slide from the receiving table D under the rearward or swinging end o't' the top E and into the cylinders (l.

Means for actuating the levers 47 comprise rods 50, 50, the forward end of which is operatively connected with the short 'arm 49 of the lever 47 while the rearward end is passed through a suitable aperture in a channel bar 5l, and is provided with a shoulder, in this case the nut 52, adapted to be engaged by said channel bar 5l. This channel bar 5l extends transversely .of the machine. and is the bar to which the rear ends of the plunger rods 53 are all attached. -The two ends of the channel bar 51 move' in guideways extending in a direction from front to rear of the machine, which guideways are formed by parallel flanges 54, ex tending from the inside of theside plates 5. whereby the bar 5l is adapted to reciprocate forward and back in guideways. The bar 51 is actuated by means of a pair of plunger rods having on their lower faces gear teeth 5G. These plunger rods are preferably the end bars of the series of rods 53, each bar carrying at its forward end one of the plungers 39. A

Transversely of the machine is a rotatable shaft :37 carrying a pair of pinions 5S, each of the two pinions being placed upon the shaft 57' in such position as to engage the teeth 5G of one of the rack bars lt follows that when the shaft 57 is rotated. the rack bars are moved forward orfbacku-*ard as the case may be. The channel bar 51 to which they are secured being sfimilarly reciprocated. and all of the plungers 39 are actuated simultaneously.

` Motion may be communicated to theshaft .37 through a gear wheel 59 mounted on said shaft, and in mesh with a spur pinion 60. located upon the shaft l2.

lnoperation. a plurality of fabric pockets F. closed at one end, are presented with their open ends opposite the forward ends of the series of 'pockets C. the latter being inthe position shown in Figs. 2 and 3. The open ends of the fabric pockets are then drawn over and upon the tubes (l. Springs S being in the troughs of the feed table D. slide quickly into the cylinders as soon as the top E is raised. The plungers 3 9 are started on their forward or spring compression stroke. `The series of swinging tops E being lowered as shown in Fig. 3. the forward movement of the plungers is continued until said springs raise the hinged top 40 of the tubes (l. thereby distending and holding the open mouths of the pockets firmly to the cylinder tube ends. The plungers 39 continuing their forward movement, force the springs into the pockets and compress them therein as shown more. clearly in Fig.

2H with the result that the pocket holders.

about to be described. operate and open and receive the major portion of the spring filled pocket. lipon the release of the t-readle, the' pocket holder parts close dow-n upon the spring filled fabric at a point in rear of the, forward end of the plungers. as clearly shown in Fig. ,13. Then the plungers are withdrawn. This withdrawal of the plungers b v means of the bodily moving of the channel bar 51 likewise actuates the arms l?. 49. to which the 'channel bars are secured. and raises the tops IC again into the position shown in Fig. 3: thus permitting the springs S to start to feed by gravity from the feed table D into the tubes C, and thereupon the operation is repeated.

The construction of the fabric holder and the lneans for permitting the action just described with respect thereto. is as follows: The holder H is an elongated metallic box made in two halves. hinged together at 61, each half comprising a front wall 62, an inturned rear wall and a connecting wall 64. It will be observed that the walls are parallel to the rear walls 62 but are not so deep. the wall 62 being. so constructed as to form the hinge 61. The halves of the holder thus open out like jaws. The holder` is of a length equal to the width of the series of tubes C. The adjacent forward margins of the rear. inturned wall are provided With a plurality of lugs with intervening recesses. as clearly shown in Fig. 14. Each of the lugs (i5 registers with a complemental, longitudimilly arranged groove' 66 in the plungers 39. These grooves are shown more completely in Figs. 13. l5 and 16. I have indicated in Fig. 13. the fabric pocket by the letter F. Then the halves of the holder H are opened in the position shown in Fig. is. the closed end of the pockets F containing the spring. are moved in between the jaws ofthe holder H. and just as the plunger v39 reaches its forward movement, the treadle 28 is released. and thereupon the two halves of the holder H are brought together and closed about the spring filled fabric pocket. The lugs 65 bear against the fabric of the pockets and guide them into the recesses 66. As the plunger 39 withdraws to the rear of the machine. away from the pockets. the springs S therein expand, somewhat, but the expansion movement is limited by the fact that the last volute of the, spring presses the fabric of the pocket against the inside of the forward wallsGB of the holder H. Further recession of the plunger 3.() and the dropping down of the hinged top r-10 of the cylinder. completely frees the open end of the pocket fabric from the cylinder. The holder H. as a whole. with the spring contained pockets thus held therein. may be `removed from the machine and the pocket ends closed by sewing or other means. while the spring is still compressed. While the pockets are being closed, a new unfilled holder H may be placed in position upon the table 22, and the operation repeated.
