ROLL HOLDING MECHANISM Original Filed Dec. 2, 1927 Invent or G. R emnsnider Patented Aug. 19, 1930 UNITED STATES PATENT ori ice GEORGE REMNSNIDER, OF BELLEVILLE, ILLINOIS" ROLL-HOLDIN G MECHANISM Original application filed December 2, 1927, Serial at. 237,189. Divided and this application filed September 4, 1928.
My invention relates to a roll holding mechanism and in the form shown is specifically applicable to a tape delivering machine, such as shown and described in my ap- 6 plication Serial No. 237,189 filed December 2, 1927, of which the present application is a division.
The object of my invention is to provide a roll holder for tape delivering or similar machine which is adaptable to various widths of tape and which will automatically center the roll in the machine.
In the accompanying drawings, which illustrate one form of mechanism made in accordance with my invention, Figure 1 is a side elevation on a reduced scale; Figure 2 is a section taken on the line 22 of Figure 3; and Figure 3 is a top plan view.
The frame of the machine comprises a right hand casting 5 and a left hand casting 6 terminating at the forward ends in circular gear'casings 7 and 8, respectively, and provided with feet 9 upon which the machine is supported. Extending between the easings 7 and 8 are a pair of feed rolls 10 and 11 to which the tape passes from the roll 12 over a tape guide 13. A handle 14 actuates the rolls 10 and 11 by means of gearing disclosed in my application mentioned above but not here shown as it is not essential to the present invent-ion.
The rear ends of the castings 5 and 6 are spaced apart by a central cross rod 15 which, together with a pair of cross rods 16, ar-
ranged one at the front and the other at the rear of the rod 15, forms the support for the roll holding mechanism. Slidingly mounted on the cross bars are a pair of roll frames 17 each provided on its inner face with a boss 18 adapted to enter the hole in the center block on which the roll is wound. Each of the frames 17 is provided with a central lug 19 forming a bearing for the rod 15 and with an elongated bearing 20 engaging with one of the rods 16. Formed on each of the bearings 20 is an extension 22 in which is pivotally mounted a downwardly projecting stud 23. 24: is the operating lever rigidly held in a stud 25 and sliding in the studs 23. Carried by the stud 25 is a short rock shaft 26 Serial No. 303,843.
passing down through the bar 15 to form a pivot for the stud and operating lever and having secured to its lower end an arm 27. Pivoted to the end of the arm by means of a stud 28 is a rod 29 surrounded by a coil as spring 30 and extending through the side frame 5. The tension of the spring 30 tends to move the arm 27 toward the left hand frame 6 and thus force the roll frames 17 toward each other.
To insert a roll of tape in the device the rear end of the operating lever 24 is forced toward the right hand frame 5 against the pressure of the spring 30 until the roll frames 17 are separated a sufiicient distance to allow the roll to enter between the bosses 18. The hole in thecenter block is brought into align ment with the bosses and the operating lever released to allow the spring 30 to force the frames toward each other and clamp the roll in'position. As the frames are in all positions at equal distances from the center line of the machine the device not only automatically adjusts itself to the width of the tape but also accurately centers the roll of tape in the machine. The pressure of the frames on the ends of the roll also actsas a brake to prevent the over rotation of the roll as the tape isunwound.
'I-Iaving fully described my invention, what U I 'claim' as new and desire to secure by Let-' ters Patent of the United States is:
1. In a device of the class described, the combination with a pair of laterally movable frames, of a pivoted actuating lever for said frames, said lever having sliding connections with one of said frames at one side of its pivot andwith the otherframe at the other side of said pivot.
2. In a device of the class described, the combination with a pair of laterally movable frames, of a pivoted actuating lever for said frames, said lever having sliding connections with one of said frames at one side of its pivot and with the other frame at the other side of said pivot, and a spring tending to move said frames toward each other.
3. In a device of the class described, the combination with a pair of laterall movable frames, of an operating lever provided with 8.
pivot, a sliding connection carried by one of said frames and engaging with the lever at one side of the pivot, and a second sliding connection carried by the other frame and 5 engagin with the lever at an equal distance at theot side of the pivot.
4. Lit-a ideviee eithe class described, the combination with a central supporting bar of two lateral supportin bars, one arrange at each side of the bar, a roll carrying frame having a sliding bearing on said central supporting bar and on one of said lateral supporting bars, a second roll carrying frame having a slidin hearing on the central supbar an on the other lateral supportmgq-hfihau'actuatinglever pivoted to said supper-tin bar and having sliding conneetions with t bearings on both lateral sillppenting bars, and a spring operating on 29 said ectuatin rod to move said frames toward eacho er.
5. Inca-device of the class described, the combination with asn-pporting bar, of a pair 01 slidingly mounted on said bar, a
swivel block carried by each of said frames, and a; pivotal operating lever having sliding r, I 5 mentwith said swivel blocks.
- 15. In; device of the class described, the
eombimation with a supporting bar, of a pair m of sl' 1y mounted on said bar, one
ofBaid frames ingprovided with an inwardly extending pro1eetion at one side of said ear and the other frame being provided with asimilarprojection on the other side of 5 the bar; a swivel bloekcarried by each of said geejectione; and a pivotal operating lever av'ing sliding engagement with said swivel In a device of the class described, the oembination with a central supporting bar of two lateral supporting bars, one arranged at each side of the central bar, a pair of firmes slidingl'y-meunted on said central bar, one of said frames lflein prolvidded with an WM 'ypre ecting earmgsi in one one 0 4 sairkleteral bars andthe other provided with a similar bearing sliding on the other fisaiemml bars, a swivel block carried by eaehef said bearings, and a pivotal operating lever having sliding engagement with sai ewiralsfloeks.
in whereof, I hereunto aifix my nighltune, this 3ldz de e of August, 1928.
