1955 L. K. FLEISCHMANN CARBON HOLDER 2 Sheets-Sheet 2 Filed Dec. 11, 1952 2,725,967 CARBON HOLDER Lester Fleischmann, Park, Ill. Application December 11, 1952, Serial No. 325,364 6 Claims. (c1. 191-426 '2 This invention relates to carbon holders for use with continuous-form stationery, and more particularly to an improved support for carbon holding blades.

The primary object of the invention is to provide improved closure members for holding the blades in the spacer members.

A further object of the invention is to provide detachable top supports for the posts on which the blades are mounted so that the blades may be removed when not in use.

Another object of the invention is to provide the posts with an eccentric mounting stud and an eccentric journal so that the posts may be turned to adjust the angular position of the blades with respect to the spacer members.

The invention is illustrated in a preferred embodiment in the accompanying drawings, in which- Fig. 1 is a plan view of a carbon holder embodying the invention;

Fig. 2 is an end elevational view showing one of the closure members locking the carbon blades in operative position;

Fig. 3 is a view similar to Fig. 2, showing the closure member and cap member in open position;

Fig. 4 is a front elevational view of the device;

Fig. 5 is a fragmentary sectional view, taken as indicated at line 5-5 of Fig. 3;

Fig. 6 is a fragmentary plan view, taken as indicated at line 6-6 of Fig. 4; and

Fig. 7 is a fragmentary elevational view, showing one of the posts mounted on the base member.

In the embodiment illustrated, a channel-like base member 8 is provided with a pair of upwardly extending posts 9 which have an eccentric mounting stud 10 extending through a hole in the base member and secured in position by means of a nut 11. The upper ends of the posts are provided with an eccentric journal 12 which is offset from the center line of the posts in the same way asthe mounting stud 10.

Between the posts 9 are a pair of spacer members 13 which are secured to the base member by means of screws 14. Each spacer member has a series of forwardly open slots 15 to receive carbon blades 16 mounted on the posts 9.

Each spacer member is provided with a closure member 17 which may be made of wire. Its lower end has a rearwardly extending arm 18 which is journaled in a recess provided in the spacer member 13 adjacent to the base member 8. The upper end of the closure member is provided with a forwardly extending finger 19 which is adapted to snap over the front end of a cap member 20 when the closure member is swung up into a slot 21 provided in the spacer member.

The cap member 20 is pivotally secured at 20a to the spacer member and is adapted to swing down over the top of the spacer member. Each cap member is provided with an arm 22 affording a bearing 23 to receive the journal 12 of the post 9. Thus, it will be understood fatented Dec. 6, 1955 2 that when the cap member is position as shown in Figs. 1, 2 and 4, the upper end of the post is secured. The cap member has a slot 24 to receive the upper end of the closure member, and a detent 25 is provided over which the arm 19 of the closure member'may be snapped. Preferably the cap member is provided with a'rearwardly extending arm 26 to facilitate opening the device when the closure member is released.

' Thespacer members are also shown with rearwardly extending arms 27 having several perforations 28 adapted to serve as bearings for the trunnions of a guide roll 29 provided with guide disks 30.

If it is desired to change the angular position of the carbon blades 16, which are normally disposed a few degrees from normal to the direction of travel of the stationery, it is only necessary to release the nuts 11 slightly and turn the posts 9 to the desired position. When the nuts are again tightened, the blades will be held in the desired position.

When it is desired to attach fresh carbon to the blades 16, it is merely necessary to turn the closure members from the position shown in Figs. 1 and 2, to that shown in Fig. 3, and the blades may be turned about the posts to a convenient position for attaching a new strip of carbon. If it is desired to remove any of the blades, the cap member 20 may be turned into the position shown in Fig. 3 and the blades turned more than to a position where they may be lifted olf of the posts.

The foregoing detailed description is given for clearness of understanding only and no unnecessary limitations should be understood therefrom, for some modifications will be obvious to those skilled in the art.

I claim:

1. A carbon holder for use with continuous-form stationery comprising: a base member provided with a pair of upwardly extending posts; a pair of spacer members mounted on said base member between said posts, each of said spacer members having forwardly open slots; a plurality of carbon blades, each pivotally mounted on one of said posts and received in a spacer member slot; spring wire closure members pivotally mounted near the base of the spacer members so as to swing upwardly to a position adjacent the forward edges of said carbon blades to releasably hold the blades in said slots; and catch means engaging said spring wire closure members to releasably hold said closure members in their upwardly swung position.

2. A carbon holder for use with continuous form stationery comprising: a base member provided with a pair of upwarly extending posts; a pair of spacer members mounted on said base member between said posts, each of said spacer members having forwardly open slots; a plurality of carbon blades, each pivotally mounted on one of said posts and received in a spacer member slot; closure members pivotally mounted near the base of the spacer members for swingable movement upwardly into locking position on said spacer members to releasably hold the blades within the spacer members; and an eccentrio mounting stud on each of said posts and extending into the base member whereby the post may be turned to adjust the angular position of the carbon holding blades with respect to the spacer members.
