De- 4, 1934 K. M. HENDERSON MEANS FOR FASTENING GELATINIZED BANDS Filed Feb. 1l, 1932 Patented Dec. 4, 1934 linnn?` KennethM. Henderson, Winnetka, Ill., assignor toDitto, Incorporated, Chicago,`Ill.,-acorpora'f i tionv of West Virginia Application February `11, 1932, serial No, 59a32sif` 1 claim. `(ci. afi- 33) The present inventionrelates to fastening devices and more 'in particular to fastening devices adapted to provide a flexible joint between two adjacent pieces of material,as for example,

the ends of gelatinized bands commonly employed in hectograph machines. i

Among the objects of the, present invention is to provide a novel fastening deviceby which the ends of pieces of material may be readily and effectively secured together to providea continuous strip of material and in which a exible joint therebetween is provided.

The present invention further contemplates the idea of providing a novel fastening means for securing adjacent ends of material together and includes a piece of material provided with openings adapted to be folded along the medial line thereof to provide an edge formed with alternately arranged and spaced projecting portions adapted to be disposed in intermeshing relation with a similar piece of material associated with the end of another piece of material. The openings formed by the folds of these projecting portions are adapted to be disposed in align- 2,5- ment when the projectingportions are `in intermeshing relation, whereby suitable means,

such as a removable key, may be received therethrough for securing these pieces of material together and to provide for a flexible joint, the 3o folded pieces of material being adapted to be readily and easily secured in any desired manner to some flexible material, such as the adjacent ends of gelatinized bands or the like, as employed in hectograph machines.

Still another object within the purview of the present invention is vto provide a novel fastening device for securing the ends of pieces of material together wherein a removable 'key is provided, this key being of such a construction v4,0 as to prevent accidental displacement or removal thereof when the same is in place for holding the ends of these pieces together.

Other objects, features, capabilities and advantages are comprehended by the invention, as

ilar to Figure 1 of the drawing, disclosing thel parts in spaced relation;

Figure 3 is a fragmentary View in cross section will later appear and as are inherently posrtaken in a planerepresentedby line 3-3 `of FigJ urel of the drawings; i Figure 4 is a fragmentary top plan view similar to Figuresl of the drawingidisclosing adjacent fpieces of material securedy togetherv b 69 means gofamcdied keymember; and "l Figure 5,is a planfIyiew of themodie,d key member shown in Figure 4 of the drawing.

VReferring now more in detail to the drawing, an embodiment of the present invention. is disclosed in association with strips or bandsof ilexible material 2 and 4, such as the gelatinized bands employed in hectograph machines; In the present disclosure, eachof these bands 2 and 4 may be wound upon spindles 6 which may be formed with hubs 8 terminating in the projecting stubs 10 adapted for insertion in journaling means which may be provided in the side frames of a hectograph machine, or the like. When these bands 2 and 4 are used as '(5 shown, and as for example in a hectograph machine, the same are adapted to pass over a platen or any other desired surface of the hectograph machine, and the same may be unwound from one spindle onto another, the present invention being concerned primarily with suitable fastening means whereby two adjacent pieces of gelatinized bands, such as 2 and 4, may be readily and conveniently secured together.`

In the present embodiment, each of the pieces of material 2 and 4 has secured to its ends or edges another piece of material 12.I Each of these pieces of material is of similar construction and is formed with a plurality of spaced openings and is folded along `the medial line thereof to provide a castellated-like edge formed with a plurality of spaced projecting portions 14. These pieces of material 12 are folded over the ends of the strips or bands 2 and 4 and may be secured thereto in any desired manner, as for example, by the stitching 16, or the like. These pieces of material 12are further stitched along the line 18 to provide a looped or folded edge 20 having a transverse opening 22 therethrough.

`As clearly showniny the drawing, theprojecting portions 14 of each of the pieces of material 12 are formed in opposite relation to the openings of the oppositely disposed piece of material so that when the ends of the bands or strips 2 and 4 are brought into adjacent relation the projecting portions 14of the strips 12 will be in intermeshing relation one with the other. When in this intermeshing relation, the openings 22 formed by the folds of the pieces of material 12 are in aligned relation in a transverse direction and are adapted to receive a removable key member 24 which is adapted to be inserted through these aligned openings for retaining these projecting portions in their intermeshing relation. The key 24 is of somewhat iiat construction and substantially rigid, and thus pro-vides a flexiblejoint' permitting relative angular movement between the ends of they strips 2 and 4 so that these strips may be conveniently rolled or unwound from a spindle or other similar element, such as the spindle 6.

In Figure 4 of the drawingis'disclosedf an alternative arrangement for securing adjacentv ends of material together. adjacent ends of material Zand 4 areiprovided with folded pieces of material 12 Which are provided With openings and folded, Vas shown in Figure 3 of the drawing, toY form a' c'astellated'- like edge provided with a plurality of spaced projecting portions 14. In this embodiment, however, these pieces of material` 12 are secured together by a key vmember 24- which, as shown in- Figure' 5 of the drawing, is formed with a plurality of space'di recesses 26 which are adapted to receive the loops: 20 of the projections 14. It Will'wbeA readily apparent that rWhen theV key-member 24 is inserted through 4the In, this figure, the

transverse opening 22 formed by the loops 20, the engagement of these loops 20 in the recesses 26 will prevent accidental displacement or removal of this key member.

While I have herein described and upon the drawing shownan illustrative embodiment of the invention, ,it is to be understood that the invention is not limited thereto but may comprehend other constructions, arrangements of parts, `details and features Without departing from the spirit of the invention.

A device for securing the ends of material together,y comprising in combination, adjacent pieces of exible material, a piece of flexible materiala secured' to each of said rst named pieces of material, said second named pieces of materialI having looped portions formed With spaced projecting portions adapted to be disposed in intermeshing relation, said projecting portions having openings adapted to be 'disposed in alignment when said'portions are in intermeshing relation, and a removable key vmember insertable through said aligned opening to secure said pieces of material together and to provide for a flexible joint.
