GEORGE H. HARDMAN, OF FALL RIVER, MASSACHUSE'FTS, ASSIGNOR OF ONE-HALF TO FRANK S. BRUNDAGE, OF FALL RIVER, [MASSACHUSETTS MACHINE FOR MANUFACTURING SANITARY NAPKINS.

neoaiss.

To all whom it may concern Be it known that 1, GEORGE H. HARDMAN, of the city of Fall River, in the county of Bristol and State of 'Massachusetts, have invented a certain new and useful Machine for manufacturing sanitary napkins and has for.

its object to produce a machine of this character which automatically inserts a prede termined amount of cotton, or other suitable absorbent material, into a fabric casing, then folds or flattens said casing and then severs the casing into predetermined lengths.

To this end the invention consists'in the novel features of construction and arrangement of parts hereinafter shown and described and more particularly set forth in the claims; 4

In describing the invention in detail reference will be made to the accompanying drawings, in which Figure 1 is a side view of my novel ma- Fig. 2 is a plan view of the same. Fig. 3 is.a longitudinal section on line 'mm, Fig. 2. F ig. 4 is a transverse section on line g y, Fig. 2. Fig. 5 is transverse section on line z2, Fig. 2. Fig. 6 is an. end View. Fig. 7 is a detail.

Referring to the drawings, 1 represents the bed of the machine which'is supported upon suitable legs or standards 2. Mounted upon .the bed 1 at one end are two pair of uprights 3 and'4, which are spaced any desired distance apart depending upon the length of filling desired for the napkin.

Journaled in the uprights 3 are two shafts 5 and 5%, upon each of which is secured a frictionffeed roll 6 and 6' respectively and 'journaled in the uprights 4 are two shafts 7 and 7','upon each of which is secured a friction feed roll 8 and 8, respectively. Extending between the uprights 3 and 4 in line with the top surfaces of the bottom rolls 6 and 8 is a table or support 9.

Mounted upon the bed 1 adjacent the upright 4 is an upright block 10 which extends across said bed transversely and-is provided with a central rectangular opening 11 extending through the same, as shown in Figs.

Specification of Letters Patent.

Patented Nov. '7, 1916.

Application filed October 19, 1912. Serial No. 726,683.

'3 and 5. Secured upon one side of the block 10-and upon opposite sides of the opening 11 are two elongated arms 12 arranged parallel to each other and to the bed 1. Formed upon the outer side of each of the arms 12 is a horizontal rib l3 and a series of ver-, tical ribs 14, as shown in Figs. 2 and 5. Removably held by friction upon the arms 12 is a tube 15.

J ournaled in the block 10 and extending through the opening 11 is the main driving shaft 16, which carries a pulley 17 mounted to rotate in the opening 11 and having its upper'surface in line with the upper surface:

of the feed rolls 6 and 8, as shown in F ig. 3. J ournaled in the free ends of the arms 12 is shaft 18 which carries a loose pulley 19, which cooperates with the pulley 17 to drive a conveyer belt or apron 20. I

Secured upon the end of the bed-1 ad jacent the free ends of the arms 12 is a bracket 21, to which is pivoted an upright adjustable frame 22 in which is journaled a shaft 23 which carries a feed roll 24, the upper surface of which -is arranged in line with the upper portion of the conveyer belt 20. Also journaled in the frame 22 directly above the shaft 23 is a shaft 25 which carries a circular brush '26 arranged to cooperate with said feed roll 24. The frame 22 is held in adjusted position by a thumbnut 27 andbolt 28 secured in the bracket 21. Secured upon brackets 29 extending from the frame 22 is a fixed knife member 30 and pivoted upon said fixed knife member 30 is a movable knife member 31 having a tail portion 32, as shown in Fig. 6. Secured to the brackets in line with the upper surface of feed roll 8 is a tableor support 33, the free end of which is arranged in line with and in close proximity to the upper surface of pulley 17.

The mechanism for driving the various parts of the machine will now be described.

Secured upon one end of the main driving shaft 16 is a fixed driving pulley 34 and a loose pulley 35.

meshes with a bevel gear 37 secured upon a shaft 38' which is journaled in brackets 39 intermittent bevel gear 40 arranged to co- Upon the opposite end of 'the main shaft 16 is a bevel gear 36 which operate with an intermittent bevel gear 41 securedupon the end of shaft 51. Also secured upon shaft 5 is a gear 42 which meshes with a gear 43 upon shaft 5. Secured upon shaft 38 is a bevel gear 44 which meshes with a bevel gear 45 upon shaft 7 and secured upon shaft 7 is a gear 46 which meshes with a gear 47 on shaft 7. shaft 38 adjacent the opposite end is a bevel Secured upon the gear 48 which meshes with a bevel gear 49 uponshaft 23. Also. secured upon the shaft 38 adjacent the bevel gear 48 is a cam 50, which'is arranged to coiiperate with the tail portion 32 of the movable knife member 31 to open and close the same. Said tail portion 32 .is held against the face of cam 50 by a spring 32. l I

The operation of the machine will be readily understood. A supply of'cotton or other absorbent material A is fed from a can or other receptacle between the feed rolls 5 and '5 which rotate intermittently. A supply of tubular fabric B is placed upon the tube 15 and said tube is placed upon the arms 12. The machine is nowv ready to be started. As the feed rolls 5 and 5 revolve,

the cotton is fed alongon the table 9 and between the continuously rotating feed rolls 7 and 7'. WVhen now the intermittentfeed rolls 5 and 5 cease to operate, the .feed rolls 7 and 7 which continueto rotate, will sever the cotton A at the point where it is gripped by the feed rolls 5 and 5 and continue to feed said severed portion 0, which constitutes the amount required for a filling for one napkin. Saidfilling G is then fed by the feed rolls 7 and 7 along the table 33 and onto the con veyer belt 20, which continues to feed it along the interior of the-tube 15. J ust before said filling C reaches the outer or free end of said tube 15, the end of the tubular fabric B is fed between the feed roll 24 and brush 26. The fillingC- is'then fed by thev conveyer belt 20 into said tubular fabric and between the feed roll 24 and brush 26, thence between the fixed knife 30 and movable knife 31 which is operated-by the cam 50, to sever the tubular fabric and a finished napkin 'D. is deposited from the machine.

It willbe seen that after the tubular fabric has'once been inserted between the feed roll 24 and brush 26, the action of the ma:

chine is entirely automatic and said ma chine will continue to deposit completed napkins until the supply of stock is exhausted. When thesupply of tubular fabric ll is exhausted, the empty tube 15 is removed from the arms 12 anda loaded tube is slipped upon said arms where it is held tion of

ribs

13 and 14.

It will be understood that various changes in the form, proportions, size and minor details of the machine may be made without departing from the spirit and scope of the invention and that the length of the filling A.

by the fricand completed napkin can be varied by simply changing. the size of the bevel gears upon shaft 38 sons to increase or decrease the speed of the feed rolls, as desired.
