Description
Oct. 11, 1955 K. FLEISCHMANN CARBON HOLDER FOR CONTINUOUS FORM STATIONERY Filed Jan. 5, 1952 I 25 90 llfy IH 7/0 f/Ql nml m TIES- E /0 United. States Patent() CARBON HOLDER FOR CONTINUOUS FORM v STATIONERY y Lester K.- Fleischmann, Chicago, Ill.` Application January s, 1952, serial Nb. 265,113 y 6 Claims. (Cl. 19m- 126) This inventionrelates to a carbon holder for use with continuous `form stationery, and in particular relates to a carbon holder in which a carbon `carrying member may be rapidly attached to` or detached from a base member. It is often desirable in employing continuous form stationerywith reusable carbon sheets to shift quickly from one set of continuous forms to another; or in using a typewriter to shift from continuous form to separate stationery.
The principal `object of thislinvention is to provide a `Carbon `holder for the re-usable carbon employed with continuous for-rn stationery `which has` a carbon `Carrier adapted forrapid` attachment to or detachment from a base member which may be used in connection with an autographic register, typewriter, billing machine or the like.
A further object of the invention is to provide a quickly detachable carbon carrying member which may be firmly and rigidly locked to the base member.
A further object is to provide a carbon holder which may be constructed from sheet material and other standard stock merely by the use of simple forming and punching operations.
The invention is illustrated in a preferred embodiment in the accompanying drawings, in which:
Fig. 1 is a plan view of a carbon carrier embodying the invention; Fig. 2 is a fragmentary plan view of the base member; Fig. 3 is a vertical sectional view taken as indicated along the line 3-3 of Fig. l; Fig. 4 is an enlarged fragmentary vertical sectional view taken as indicated along the line 4 4 of Fig. 1; Fig. 5 is an enlarged fragmentary vertical sectional view taken as indicated along the line 5-5 of Fig. 3; and Fig. 6 is an enlarged fragmentary sectional view similar to a portion of Fig. 3.
Referring to the drawings in greater detail, a base member is formed of sheet material, and has at one end an integral upturned handle receiving portion 11 to which a forwardly extending handle 12 is secured by means of screws and nuts 13. A pair of studs 14 may be riveted to the base member so that it may be attached to a carbon holder carriage on the travelling carriage of a writing machine. The base member 10 has a pair of aligned, spaced upwardly struck bosses 15 each of which has a rectangular aperture 16 in its flattened upper surface. A latch member, indicated generally at 17, includes a mounting pin 18 which extends loosely through an aperture 19 in the base member, and a body portion 20 which is secured to the upper end of the mounting pin 18. A washer 21 surrounds the pin 18 beneath the aperture 19, and a compression spring 22 surrounds the pin 18 and is retained between the washer 21 and a spring retainer cup 23 adjacent the lower end of the pin. The spring 22 serves to retain the latch member 17 yieldably in an upright position in the opening 19. The body of the latch includes a handle portion 24 and an arm portion 25. Preferably a detent 26 is struck upwardly `from the base member to afford a stop to limit rotation ICC of the latch member 17 when it is moved to latching position.
A carbon carrying member, indicated generally at 27, has an inverted channel shaped body 28 and a pair of upstanding guide posts 29 adjacent its ends Which serve as guides for continuous form stationery and which receive the carbon carrier blades 30 which are slotted adjacent their ends to slip onto the posts 29. The carbon carrier blades 30 may have downwardly struck detents 31 by means of which they are separated from the channel portion 28 and from adjacent blades on the same post. Clips 32 may be provided to attach carbon sheets to the blades 30.
The channel member 28 has a pair of downwardly struck, short, transverse hooks 33 the open ends of which extend in the same direction and are disposed at a slight downward angle with respect to the top of the channel portion 28. As best seen in Fig. 6, the transverse hooks 33 may extend through the apertures 16 in the tops of the bosses 15 on the base member, and may interlock with the bosses adjacent said apertures 16. The angular disposition of the hooks provides a wedging action as the hooks are engaged with the margins of the apertures so that the carbon carrying member 27 may be very rigidly held with respect to the base member 10. When the carbon carrying member 27 is hooked onto the base member by engaging the hooks 33 beneath the margins of the apertures 16, the latch means 17 may be rotated from the position shown in Fig. 2 to the position shown in Fig. 1, so that the arm portion 25 abuts against the adjacent end of the carbon carrying member 27 and forces the hooks 33 firmly into engagement with the margins of the apertures 16. The yielding mounting of the: latch means 17, afforded by the loose fit of the pin 1S in the aperture 19 and the coil spring 22, permits a stiff yielding engagement of the latch member with the carbon carrying member 27.
When the device is in use the superposed strips of continuous form stationery are led between the guides 29, and one of the carbon carrier blades 30 extends between each adjacent pair of strips, with a sheet of carbon paper attached to the blade in the conventional manner. The outermost set of forms of the strip of forms is in position for use with the carbon sheets interleaved. However, if it is desired to switch to a different form, or in the case of a typewriter if it is necessary to use the typewriter with separate stationery, it is merely necessary to rotate the latch 17 to the disengaged position shown in Fig. 2, slip the carbon carrying member 27 to the left to disengage the hooks 33, and lay the carbon carrying member and attached carbon sheets and continuous form strips on the supply box for the continuous form stationery. A different set of continuous form stationery may then be substituted by clipping in the carbon carrier on that set; or if a typewriter is being used the typewriter carriage is relieved of the carbon carrying member and of the undesirable transverse pull which is produced when a continuous form strip is secured to the carriage.
The location and dimensions of the body 20 of the latch 17 are such that the body provides a guide which aids in positioning the hooks 33 properly with respect to the apertures 16 when the carbon carrying member 27 is being secured to the base member 10.
The foregoing detailed description has been 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.
