RIBBON-ATTAGHING- MEANS.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed April 5, 1920. Serial No. 371,249.

T 0 all whom it may concern:

Be it known that I, BENJAMIN H. TAN- NER, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Ribbon-Attaching Means; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in ribbon attaching means, and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

One of the objects of the invention is to provide a simple and eflicient means for removably attaching one end of a ribbon to a s 001.

Another object of the invention is to provide means of the kind, which may be re movably attached to the ribbon in such manner that it may be detached from a worn out ribbon and may be readily attached to a new ribbon, without the aid of tools.

These objects, as well as the several advantages of the invention will more fully appear as I proceed with my specification.

In the drawings Figure 1 is a perspective view of my improved means attached to a ribbon, and in a position to be removably connected to a spool.

Figs. 2, 3 and 4C, are detail cross-sectional views, on an enlarged scale, illustrating the manner of applying said means to a ribbon, and thereafter connecting the same to a spool.

Fig. 5 is a longitudial sectional view through one end of the spool and attaching means, the plane of the section being inclicated by the line 55 of Fig. 4

Referring now in detail to that embodiment of the invention illustrated in the accompanying drawings 10 indicates a ribbon spool such as is used in a multigraph machine. Said spool comprises a tubular, sheet metal barrel 11, having end flanges 12, and a longitudinal slot 13which terminates short of the said flanges.

14 indicates one end of a reproducing or inked ribbon which in use, is unwound from one spool and wound upon another like spool, and vice versa, said ribbon being of a width substantially equal to the length of the spool barrel 11. Means are provided which may be removably secured to the ends is of a length approximating that of the slot I 13 in the barrel 11, but its bifurcations are spread apart toward their ends so as to occupy a space wider than said slot.

16-16 indicate the bifurcations or side members of the wedge, which diverge outwardly from a rounded apex 17 Said side members are bowed outwardly intermediate the apex 17 and their ends or the base of the wedge, as indicated at 18. Near their ends, the outward bow 18 in each case, terminates in a reversed curve which ends in a laterally extending flange 19, running the length of the wedge.

Asosciated with the wedge member for the purpose of removably securing one end I of the ribbon 14: to it, is a. V-shaped key or spline 20. Said key is made of sheet metal and has straight diverging, resilient sides 21, which may be forced into the wedge member, to hold an end of the'ribbon against:

the inner faces of the bifurcations or sides of the wedge member 15.

To removably secure the ribbon 1 1 to said wedge member, one end of said ribbon is placed so as to extend across the space be:

tween its flanges 19 and is held in this position by one hand of the operator making the attachment. The key 20 is then alined with said space between the flanges of the Wedge as shown in Fig. 2, after which the key is pressed inwardly between said flanges, the

bowed sides of the wedge yielding-to allow said key to pass; As the key is inserted, it carries the ribbon end with it into the wedge,

and, when released, it will spring back to its M normal shape and engage and clamp the ribbon end between itself and the inner faces of the side members of the wedge, as shown in Figs. 1 and 3.

With the ribbon thus secured to the wedge member, the apex 17 of said wedge is inserted into the slot 13 in a direction radial tothe spool barrel and a compressive pressure, as by the thumb and finger, is brought to bear upon the flanges 19. This will cause the bowed parts 18 of the sides of said wedge to yield inwardly toward each other so that said bowed sides will pass through said slot after which said parts will spring outwardly to their normal position, and the flanges 19 of said wedges will bear upon the outer surface of marginal parts or the. barrel defining the slot 13 therein, as shown in Fig. 4-. With the parts in this position, the flanges 19 prevent the wedge from falling bodily into the interior of said barrel, while its bowed side members present abutments whichlock it against withdrawal radially outward through said slot.

pass the edges ofthe slot '13 of the barrel,

whereupon the wedge 15 is withdrawn radially'outward through said slot and thus disconnected from the spool. V

A pencil or match or any other handy device or implement is inserted into one end of the wedge to push the key 20 out through theother end of the wedge, where the exposed end of the key isigrasped by the fingers and pulled out of the wedge, after vwhich the ribbon may be withdrawniironi. the wedge, through the space between the flanges 19. Said key and wedge may be applied to the end of a new ribbon and the wedge again inserted in place through the slot as before described.

It isapparent that my improved attaching means has many advantages. It does not require the making of special spools and is capable of being used in connection with the same spools now used in multigraph machines. wherein the attaching device is permanently secured to the ribbon. It may be used indefinitely as it is not thrown away when the ribbon is worn out, but may readily be applied to new ribbons to again attach ,said ribbons to the old spool. It requires no special machinery or skilled operators to attach thesame to a ribbon and its conformation is such'that it cannot bend or get out of shape. Other advantages will be apparent to those skilled in the art.

While I have described the invention as applied to a spool for multigraph machines ited thereto, except as pointed out in the appended claims.

I claim as my invention 1. In combination with a spool barrel having a longitudinal slot therein, a wedge member adapted to be inserted through said slot in a direction radial to the barrel, said wedge'niember having sides which diverge from the apex of the wedge to its base, where they terminate in oppositely disposed longitudinal flanges adapted to engage against the barrel at either side of said slot, the divergent sides of the wedge being bowed outwardly intermediate said apex and said base to present rounded abutments adapted to resist the withdrawal of the wedge member through said slot, and means for attaching a ribbon to said wedge member.

2. In combination with a spool barrel having a longitudinal slot therein, a, wedge member adapted to be inserted through said slot in a direction radial to the barrel, said wedge member having sides which diverge from the apex of the wedge to its base, where they terminate in oppositely disposed longitudinal flanges adapted to engage against the barrel at either side of said slot, the divergent sides of the wedge being bowed outwardly intermediate said apex and said base to present rounded abutments adapted to resist the withdrawal of the wedge member through said slot, and means for detachably connecting a ribbon to said wedge member. r

3. In combination witha spool having a tubular barrel provided with a longitudinal slot therein, a wedge member adapted to be inserted through said slot in a direction radial to the barrel, said wedge; member having sides which diverge from the apex of the wedge to its base, where they terminate in oppositely disposed longitudinal flanges adapted to engage against the barrel at either side of said slot, the divergent sides of the wedge being bowed outwardly intermediate said apex and said base to present rounded abutments adapted to resist the withdrawal of the wedge member through said slot, and means for detachably connect- ,ing a ribbon to said wedge member.

a. In combination with a spool barrel having a longitudinal slot therein, a wedge member adapted to be inserted laterallyinto said slot, said wedge being'of a width greater than'said slot and including parts adapted toyield in passing through said slot and to thereafter expand .to secure said wedge in said slot, and a key adapted to be yieldingly engaged within said wedge member for securing a ribbon to said wedge member.

5. In combination with a tubular spool barrel having a longitudinal slot therein, a sheet metal Wedge member adapted to be inserted laterally into said slot, said wedge member being of a width greater than said slot and including parts adapted to yield in passing through said slot and to thereafter expand to lock said wedge in said slot, and a key adapted to be yieldingly engaged within said wedge member, said key and wedge removably securing one end of a ribbon between them.

6. In combination with a tubular spool barrel having a slot therein, a wedge member having side members, which include laterally extending flanges, said wedge member being adapted to be inserted laterally into said slot until stopped by the engagement of said flanges with parts of said barrel adjacent the slot, and a key associated with said Wedge member for detachably securing one end of a ribbon within said wedge member.

7 Means for removably attaching one end of a ribbon to a slotted spool barrel comprising, a substantially V-shaped sheet metal, yielding, elastic wedge member, which includes divergent sides that terminate in outwardly extending flanges, each side being bowed outwardly at its middle, and a V- shaped sheet metal key adapted to be inserted into said wedge member, and to expand to hold one end of said ribbon against the inside faces of said wedge member.

In testimony that I claim the foregoing as my invention, I affix my signature in the presence of two Witnesses, this 26" day of March, A. D., 1920.
