This invention relates to improvements in pad making machines, and is particularly adapted to be used in'connection with steel wool cutting machines, and machines used for assembling steel wool into ribbons.

It is particularly the object of this machine to receive ribbons of steel wool and to cut the ribbons into definite lengths, and after the ribbons have been thus cut into lengths to first roll the sections of ribbon into bundles or rolls and thereafter lcompressing them into Hat pads.

It is particularly the object of this invention to provide in one apparatus means for cutting ribbons of steel wool into definite lengths and feeding'these sections of ribbon by means of a conveyor belt to a art of the device where these sectionsl are rst rolled and thereafter in the same continuous action to flatten these rolls into flat pads.'

It is also an object of this invention to provide in connection with an apparatus of this kind means for feeding ribbons of steel Awool, of different thicknesses, and for that purpose the feeding apparatus is adapted t0 automatically adjust itself to the thicknesses of the ribbons.

It is a further object of this invention to provide in connection with the feeding, cutting, rolling, and flattening apparatus one means for operating all of these parts at one time, and simultaneously with each other so that as the Aribbons of steel wool are fed into one part of the apparatus the rolls will be fed out at another part.

It is also an object of this invention to provide an apparatus of this kind that is automatic in all respects, easily operated and when started needs very little care or super- `vision during the running.

Figure 11 is a view showing how the steel wool strands coming from a steel wool ma-l chine are collated into a strip of steel wool ribbon.

This apparatus is completely shown in side elevation in Fi re 1, vand is adapted to be used in connectlon with steel wool forming machines after the wool or strands of wool have been assembled into groups in the form of ribbons. The numeral 1 designates a platform supported by rollers 2. Upon the platform is a motor 3 used for power for operating all of the moving parts of the apparatus. This motor has the usual motor shaft, upon which, there is a pulley 4.

Extending transverse the platform, as'

a top plan view of the front 12 which is connected by a belt 13 to the pulley 12. This belt 13 travels over and around the pulleys 12 and 12 to rotate shaft 10.

Extending from the platform 1 are uprights 14. In the drawings there are shown four of these uprights, constituting the rectangular frame, which has on the top thereof a rectangular frame 15. Extending from the frame 15 are upright brackets 16, two in number, which support on the top thereof a shaft 17. Extending horizontally from the brackets 16 are arms 20 which have in the outer ends thereof a shaft 21. On shaft 17 is a gear 22 meshing with a gear 23 on shaft 21. On one end of the shaft. 21 is a pulley 18 connected by a belt 19 with the pulley 9 on the shaft 5.

Supported in the brackets 16 between-the frame 15 and the shaft 17 is a shaft 24, which has adjacent one end thereofl a gear 25 in mesh with gear 22. On the front end of shaft 24, as shown in Figure 1, there is a 1'0- tating feeder or notched roller 26. Extending from shaft 21 and pivotally supported thereby are links 27 which carry a shaft 28. This shaft 28 has a gear 29 meshing with ears 25 and 23, and also meshing with each other. All of these gears are driven by the pulley 18 through the shaft 21 and rotate in unison.

On the front end of the shaft 28, as seen in Figure 1, is a feeder or notched roller 30 which cooperates with the feeder or notched roller 26, for feeding ribbons of steel wool to the knives located beneath the notched rollers so that definite lengths of the ribbon may be cut oftl as it passes through or between these rollers. It is obvious from an 'examination of Figure 1 that these feeders or notched rollers may be spread apart, owing to the fact that the links 27 are pivoted at their upper ends. To the lower ends of the links 27 there is attached one end of a spring 31, the other end ofwhich is attached to some part of the brackets 16.

To one of the brackets 16 there are attached upright guides 32 flared at their upper ends. To the lower parts of these upright guides is attached a curved guide plate 33. The purpose of these guides is to receive 'and guide the ribbons of steel wool. The ribbon passes between the upright guides 32 and over the curved guides 33, down between the feeders or notched rollers 26 and 30, from which the ribbon is guided down between two cutter blades,y hereinafter described.

In Figure 11 there is shown a steel wool machine from which strands of steel wool 32a are emerging and are collated or gathered together in a ribbon by means of a hook 325. After the strands have been formed into a ribbon, as shown in this figure. the ribbon is fed into the machine, where it is cut into proper lengths for being formed into pads.

On the outer end of shaft 10 is a pulley 34. Extending downward from the frame 15 are three brackets 35, which have sockets or holes therein in which a shaft 36 rotates. On the outer end of the shaft 36 is a pulley 37 connected to pulley 34 by means of a belt 38. It is obvious that by the rotation of the shaft 10 from the motor the shaft 36 is rotated through belt 38.

Near the 'center of the shaft 36 is a beveled ear 39, while near the end thereof remote rom the pulley 37 is another beveled gear 40. kThe gear 39 meshes with a beveled gear 41 upon a vertical shaft 42, rotating in a housing 43. On the upper end of the shaft 42 is a beveled gear 44. Meshing with gear 40 is a gear 45 around a second vertical shaft 46, rotating in a housing 47. This shaft 46 has on its upper end a beveled gear 48.

Suitably supported upon the frame 15 are brackets 49, two in number, one supporting for rotation a shaft 5() and the other a shaft 57. On one end of shaft 50 is a gear 51 meshing with the gear 44. On the other end of this shaft is a similar gear 51 which meshes with a gear 52 on a vertical. shaft 53, rotatable and carried in a housing 54 suitably supported by Athe frame 15. On the lower end of the shaft 53 is a cutter blade 55. Meshing with the gear 48 is a beveled gear 56 on the horizontal shaft 57 in the other one of the two brackets 49. This shaft also carries agear 58 which meshes with a gear'59 on a vertical shaft 60, rotatably mounted in a housing 61 supported by the frame 15. On the lower end of the shaft 60 is a cutter blade 62 cooperating with a cutter blade 55 for cutting the steel wool ribbon into sections as it asses' down between the crimpers or notched rollers.

It is obvious from thepforegoing description that as the steel wool ribbon is fed over the guide plate 33, down between the crimpers or notched rollers it will be uided between the cutter blades and perio ically be cut into short lengths, depending upon the speed of rotation of the shafts that carry the knives with relation to the shafts that feed the ribbon of steel wool.

Extending from the pulley 8 is a belt 63 which passes over a' pulley 64 on a shaft 65. This shaft is located on the front or feeding end of the rolling and pressing part of the apparatus. On the other end of the shaft 65 from the pulley 64 is a pulley 66. This shaft 65 is supported in one end of the longr frame composed of two channel irons 67 held in spaced relation to each other,-as shown in Figure 2. Between these channel irons and upon shaft 65 is a pulley 68. The pulleys 64, 68 and 66 are fastened upon the shaft 65 to rotate with it.

At the other end kof the frame and between the other ends of the channel irons is a pulley 69, near which there is an idler 70. Passwool ribbon as they drop from the cutting machine located immediately above this part of the apparatus.

It is obvious from an examination of Flgure 1 that while the parts here are shown in cooperation with each other and operated fromthe same source of power, they may be separate and the cutting machine operated independent of the rolling and pressing part of the apparatus. Allthat is necessary to accomplish this is to remove the belt 63 from the pulley 64, when the frame composed of the channel iron 67 may be removed from the other part of the apparatus.

While the upper part of the runway has slanting walls the lower part has vertical walls, indicated by the numeral 73. Between these vertical walls there is located a presser strip or board 74 attached adjustably thereto by means of brackets 75, having slots 7 5a to receive screws or bolts "7 5b located in the walls 73. Adjacent the lower end of the vertical walls 73 is a shaft 76: This shaft has on one end, outside of the vertical walls, a pulley 77 and between the Vertical walls a pulley 78. Extending from the pulley 77 to pulley 66 is a belt 79 for the purpose of causing the shaft 76 to rotate. On the extreme lower end of the vertical walls 73 is a shaft 80. O n this shaft is a pulley 81. Between theY pulley 81 and the pulley 78 is an idler 82. Around the pulleys 78 and 81 and around the idler 82 is a belt 83.

. It will be noted from an examination of' Figure 1 that the pulley 78 is not in line with the pulley 81 and the idler 82 being somewhat elevated to provide a lar er entrance space between it andthe belt 1 than between the other members and the belt 71.

For the purpose of supporting the channel .iron frame there is provided a truck `plat form 84 supported by rollers 85. Extending from the platform is a frame 86 to which the channel 1rons are pivotally attached at a point indicated by the numeral 87. On the ower -end of the channel irons adjacent-the pulleys 69 is a bracket 88, attached to the lower end of which are rollers 89. The purpose of the rollers 89 and 85 is to permit this part of the apparatus to be transported inde'- pendent of the parts supported by the rollers 2. As hereinbefore described, these parts are separate one from-the otherfand may be operated independently one of the other and by means of these rollers they may be transported from one place to another as separate and distinct units.

As the ribbons of steel wool are fed between the feeders or notched rollers and cut' into short sections byI the knives, these sections fall upon the traveling belt and are fed down to the presser strip or board 7 4. When these 70 sections come in contact with the presser strip or boardthe frontend, on account o f the friction between the board and the sections of steel wool ribbons, the sections of ribbon begin to roll and are formed into round balls,

cylindrical in shape AThis is brought about from the fact that while the end of the ribbon is checked, on account of the fixed board, the ribbon is still traveling, due to the movement of the belt that supports it.

y As these round rolls 90 travel with the belt and roll under the strip or board they finally reach the lower end of the presser strip or boa-rd and come in contact with two traveling belts spaced one from the other at the en-85 trance point, but as these belts travel they approach each other and force what was at one' time round rolls of steel wool into flat pads 91, rectangular in shape. After these pads have thus passed through the two rollers at the lower end ofthe frame they are ejected as a finished product. This last step of attening the 'rolls forms no part of this invention.

I desire to comprehend within my inve- 96 tion such modications as may be clearly embraced within my claims and the scope of my invention.
