This invention relates to gelatin band spindles for hectograph duplicating machines and its object is to provide a novel and improved spindle adapted to be readily and easily mounted in a machine and to be engaged with carrier devices for storing the roll.

A further and important object of the invention is to provide a strong and substantial spindle comprising a body made of wood or other light material and provided with metal journal end members permanently and rigidly secured to the body so that they will not twist or turn relatively to the body 111 service.

And a further object of the invention is to provide an adapter for enabling the spindle to be used in a variety of machines.

In the accompanying drawings illustratin a selected embodiment of the invention,

Fig. 1 shows the spindle mounted in parts of a machine shown in section.

Fig. 2 is a sectional view through the spin dle, the adapter and the parts of the machine in which they are mounted.

Fig. 3 is an end view of the left end mem ber of the spindle in Figs. 1 and 2.

Figs. 4 and 5 are transverse sectional views on the lines 44 and 55 respectively of Fig. 2.

ig. 6 is a perspective view showing the left end of the body and the metal journal end member to be engaged therewith.

Fig. 7 is a perspective view showing the right metal journal end member and the adapter.

Referring to the drawings, 8 is the body of the spindle which may be made of wood or other light material and of a suitable size. The body is provided with metal journal end members 9, 9, which are preferably made alike. Each journal end member 9 has a socket portion 10 to receive an end of the body which is reduced to form a peripheral shoulder 11 to abut the socket wall, whereby the end member will lie flush with the body and present a smooth surface to receive the gelatin band. The end member is secured on the end of the body against relative rotative movement by any or all of the following means :The side wall of the end member may be indented at any place or places, as at 12, to clamp the body; the bottom of the socket may be provided with a transverse rib 131:0 engage a corresponding groove 13 in the end of the body; or one or more sharpened ribs or projections of suitable size may be provided on the inside of the socket wall to cut into the body 8 when the end member and the body are engaged. The rib and groove are preferred because they will. absolutely insure against relative rotative movement of the body and end member, but the sharpened ribs or projections 13 con stitute a satisfactory interlocking means for many purposes; and the indentations 12 are a desirable feature since they can be easily made to press into the Wood body and prevent relative rotative and also relative longitudinal movement of the body and end member. There is often considerable rotative strain on the spindle and heretofore it has not been uncommon to find the body rotating relatively to the end members of the spindle, but there is little tendency of the body and end members to loosen or separate longitudinally, therefore it will be found suflicient ordinarily to provide the rib and groove for preventing relative rotative movement and one or more indentations like, or similar to 12 to prevent relative endwise movement.

I prefer to make the end members alike so that they can be used interchangeably in the supporting parts of a machine or of a storage carrier and I provide each end member with an elongated journal 14 which projects beyond the other parts of the end member and is adapted to engage supporting parts in the machine or the storage carrier.

In Figs. 1 and 2, the journal at the left of the spindle is shown engaged with an adapter 1:") including a screw-threaded stem 18 fast in a member 16 which is rotatably mounted in the machine frame (not shown) or the like. Unitary with the adapter 15 is a centrally located boss 21 projecting axially from the adapter and an openin 22 extends through the boss and into the main body of the adapter and is enlarged as at 23 and the outer end of the opening is countersunk as at 24.

Extending outw: 'dly from the boss 21 is a lug 25 and the sides of this lug extend radially from the boss. Projecting axially from the ends of the end members 9 at the periphery thereof and spaced from the elongated journals or center pins 14 are lugs 26. These lugs are spaced from each other and when the center pin ll is passed through the opening 22. the lug 25 its between adjacent lugs 26 which are circuniferentially spaced from each other. I prefer to provide three lugs 26 for then when the lug 25 is titted between adjacent hws and the adapter 15 is rotated in either direction the hip; is so disposed relative to two lugs 26 that the spindle will start to turn at once. However, the end members 9 need have but one lug for the adapter 15 may be rotated in either direction and the lug 25 sooner or later will engage the single lug 26 and cause rotation of the spindle. Thus, while the provision of three lugs is advantageous one or more lugs may be provided without departing from the purview of my invention.

The invention provides a strong and substantial spindle for gelatin bands which is adapted to be readily and quickly engaged with and disengaged from the parts of a duplicating machine for supporting the spindle, and also with a carrier in which the gelatin band roll is stored when not in use. I prefer to dispose the sides 27 of the lugs radiall of the spindle to make the spaces be tween the lugs as wide as possible at the periphery of the spindle where they will be first engaged with supporting parts. Furthermore, since the sides of the lugs 26 are in radial planes the sides of the 111;;25 will neatly h't thereagainst to provide a good driving connection between the lugs 25 and 26. I have provided strong and substantial metal journal ends and novel means for securing these ends on the body because I know that in practice it not infrequently happens that the journal ends are broken or distorted in use or in handling and work or are forced sufficiently free to revolve on the body or to permit the body to revolve relative thereto. The journal ends of my invention are strong and substantial and are rigidly and permanently secured to the body.

I have shown the invention in a preferred form adapted for commercial use, but I reserve the right to make changes in the construction and arrangement of parts within the scope of the following claims.
