7 Claims.

This invention relates generally to printing equipment and more particularly to a quoin. Quoins are subject to frequent and hard use and abuse and must operate quickly and easily and it is an object of our invention to produce a quoin which is capable and ecient in service.

Briefly described, our invention consists of a channel having an outside Wedge therein together with means for forcing `these members away from each other in a straight line, such preventing squabbling of the type, and also exerting the pressure against the type to produce the most efficient action thereon.

One aim of our invention is to create a quoin which may be manufactured in any desired length, and we do this by making the elements of the quoin of recurrent configuration whereby they may be cut olf to the proper length without Waste. Another advantage of our invention is the method of connecting the outside wedge to the webs of the channel member, such guiding the movement of these respective parts whereby they must move in the desired direction. Also, the same means prevents the total separation of these parts whereby a self-contained unit is had.

Still another advantage lies in the guiding bushing for the key, this bushing being flush with the outer surfaces of the channel member to form a sturdy and neat appearing structure. Also, the operative end of the bushing is readily found as such is circular in shape whereas the other end is of semi-circular shape. Hence, the key must be inserted from the correct side, thus insuring clockwise rotation thereof to tighten the quoin,

thus giving a uniformity which makes for speed.

Further advantages are due to the positioning of the several elements whereby inherent advantages relating to strength of the working parts and compactness of structure is had and these will be appreciated as the description proceeds.

In the drawing:-

Fig. 1 is a plan view of a chase equipped with two of our improved quoins.

Fig. 2 is a cross sectional view taken along the line 2 2 of Fig. 5.

Fig. 3 is a View in section taken along the line 3--3 of Fig. 2, the operating key being shown in dotted lines.

Fig. 4 is taken along the plane of the line 4--4 of Fig. 3.

Fig. 5 is taken along line 5-5 of Fig. 2.

Fig. 6 is a perspective view of the shell member.

Like numerals refer to like parts throughout the several views.

In Fig. 1, 10 indicates the type, 11 the frame therefor, 12 the reglets and 13 our novel quoin.

As is clearly shown in Fig. 5, indicates a Channel member having slots 22, see Figs. 1 and 2, and 3o indicates the outside wedge member, such being slidably engaged by the flanges oi' the channel member 20. The wedge member 3G has staggered parallel surfaces 31 as clearly shown in Fig. 2. Pins 32 extend through the outside wedge member and ride in the slots k22, see Figs. 2 and 5, to guide the movement between these two members and also to prevent their separation. Thus a self-contained unit is had.

, An inside wedge member 40, having inclined surfaces 41, see Fig. 2, is located between the outside wedge 30 and the web of the channel member. This inside wedge member is cut away at its center to form teeth thereon.

A shell member 75, see Figs. 3 and 6, extends ,25 between the flanges of the channel member 2i), the upper end being circular in shape and snugly fitting a corresponding hole, being brazed therein as indicated at '76, while the lower end, shouldered as indicated at 77, is semi-circular and is likewise received snugly in the other ange of the channel,` thus absolutely preventing any rotation from occurring. The shoulder 77 insures proper positioning of the shell. See Fig. 3.

The operation is apparent. The quoin is inserted in position, for instance, as shown in Fig.

l, and the circular openings of the shell 'l5 prevents any reversed positioning o the quoin, and thus the key member 80 will always be rotated in a clockwise direction to cause an expansion of the quoin. This sameness of operation makes for speed. Y

Upon rotation of the key 80, the rack teeth 60 and the wedge member 40 are moved from the position opposite that shown in Fig. 2 to that 55 shown therein and this causes the outside wedge member 30 to engage against the adjacent reglet 12 while the channel member abuts against the frame 11 and the type 10 are tightly locked in position without any sidewise movement what- 'ibo soever.

The release of the quoin is accomplished in a reversed manner and the pins 32, riding in the slots 22, prevent any separation of the several parts. Moreover, the parts are substantially en- T closed whereby protection thereof is had.

The invention is defined in the appended claims and is to be considered comprehensive of all forms coming within their scope.

We claim:

1. A quoin comprising, a channel member, a wedge member tting between the flanges of said channel member, said wedge having wedg ing surfaces thereon, a second wedge member having wedging surfaces engaging the surfaces 0f the first mentioned wedge member and located between said rst mentioned wedge member and the channel member, means including a key for forcing said rst mentioned wedge member away from the said channel member and guiding means for said key member, said guiding means being located in but extending unsymmetrically with respect to the opposite flanges of said channel member for the purpose described.

2. In combination, a channel `shaped member, an outsidewedge member slidable between the Webs thereof, an inside wedge member having teeth thereon, said channel member having a circular opening through one ange and a substantially semi-circular opening through the other iiange and a cylindrical shell adapted to be received in said openings, said shell being cut away for the purpose described.

3. An article of manufacture consisting of a channel member of identical cross section along its entire length, an integral outside wedge of recurrent cross section slidably engaged between the flanges of said channel member, means for preventing lengthwise movement of the wedge with respect to the channel member, said means including pins extending through said outside Wedge at both sides and being received in slots in the flanges of said channel member, and means for forcing the said members apart.

4. A quoin comprising, two members movable relatively to each other, means for moving the same comprising a rack adapted to receive a key and means for holding the key against separation from the rack, said means being located in the same plane as the said rack.

5. A combination of elements as per claim 4 in which said means also prevents movement of the key toward said rack.

6. In combination, a channel shaped member, an outside wedge member adapted for lateral movement between the ilanges of the channel, an inside wedge having teeth thereon, adapted for longitudinal movement between the outside wedge and the web of the channel, a cylindrical shell extending through and between the langes of the channel adapted to receive a key, said shell being cut away to allow for longitudinal movement 4of theV teeth on the inside wedge, whereby rotation of said key moves the inside Wedge to force the outside wedge away from the channel, and said inside wedge abutting the cylindrical shell to limit the movement thereof.

'7. In combination, a channel shaped member, an outside Wedge member slidable between the flanges thereof, an inside Wedge member having teeth thereon, the anges `of said channel each having an opening therein, a cylindrical shell inserted and secured into said openings, one end 0f said shell being shaped to receive a key therein and the other end of said shell being shaped so that a key cannot be inserted therein, said shell being cut away for the purpose described.
