ASSIGNOR TO MILLER SAW- FENNSYLVANIA,

' CORD-RETAINING MEANS.

Application filed April 8, 1919.

ToaZZ whom it may concern:

Be it knownthat I, lVAL'rER E. SMITH, a subject of the King of England, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Cord-Retaining Means, of which the following is a specification.

This invention relates to an improvement in sheet retaining means, used in conjunction with the platen grippers of a platen press.

In the operation of a platen printing press, it is frequently necessary to supplement the action of the usual sheet grippers, in order that the printed sheet may be evenly drawn from the type, or the tendency of such sheet to stick to the type overcome, during the printing operation. Ordinarily, this supplemental gripping means has been supplied by the pressman tying the ends of one or more pieces of cord to the respective grippers, so that the cord may bear pen the sheet across and between the grippers. It is, a comparatively dirficult and slow operation to secure the cord in place with just the proper tension, particularly where one or more such cords are used.

The present invention is designed to provide a means, in the form of a clip, which may be readily applied to the grippers, and which is so constructed that when in place the usual retaining cord maybe readily and quickly connected to such grippers, with just the proper degree of tension, and with materially less expense of time and labor than in the method heretofore practised.

In the drawings Figure 1 is a plan view, illustrating the application of the improvement.

Fig. 2 is an enlarged broken plan of one of the clips in place, with one end of the cord secured thereto.

Fig. 3-is a section on line 3-3 of Fig. 2.

Fig. 4 is a section on line 44 of Fig. 2.

Fig. 5 is a section on line 5-5 of Fig. 2.

Fig. 6 is a plan illustrating the use of the clip as a means for securing a blocking-out strip to the gripper.

Fig. 7. is a section of the same.

This invention is here shown as applied to the grippers 12 and 13, of a platen press, which grippers are mounted ordinarily on the rocker bar 11, by bolts 14:, and cooperate with the platen 10 of the press, in the usual manner. Ordinarily these grippers will Specification of Letters Patent.

hold the sheet from being drawn from the platen as the type recede, but frequently the work on hand is of such a nature that additional transverse paper holding means must be used. Under the circumstances it has long been customary to secure a cord, as 18. to the respective grippers 12 and 13, by wrapping the end of the cord'one or more times about the grippers and tying the same in place. This is not only. a somewhat tedious operation, but where one or more cords are used, it is rather diflicult to secure all such cords in place with even tension, and hence the slack cord will be of little advantage.

The retaining clips,- shown at.16 and 17 in the drawing, are designed to provide a means to permit the necessary cords to be readily and quickly secured in position with their tension, during such application, under direct control, so that all cords will act evenly on the paper.

The improved clip, as here shown, comprises a plate 19, of substantial length, but of somewhat less width than that of the gripper. One edge of this plate is provided near each end thereof with spring tongues, formed by integral projections on the plate 19 which are bent upwardly at the edge of said plate, as at 20, 21, a distance substantially equal to the thickness of the gripper, and then projected rearwardly to form the spring sections 22, 23.

The edge of the plate 19 provided with the tongues, is also formed about mid-distance between said tongues with a cord engaging lip 25. This lip has a rounded outer edge, and its inner edge is integral with the plate 19 for a comparatively short length of inner edge, as at 24. The remaining portion of the inner edge of the lip is spaced from the edge of the plate 19, as at 26, forming a retaining slot, the walls of which slightly converge, as shown.

The improved clip is, as will be readily apparent readily and conveniently applied to the gripper, by forcing the clip over the inner edge of the gripper, so that said clip is gripper through the spring pressure between the tongues and plate. The clips are applied so that the cord engaging lip projects beyond the inner edge of the gripper, as shown in Fig. 1, and while the application of the cord to the clips may be carried out in any desired manner,

place is extremely simple.

it is preferred that the cord, which may be curely held, all as particularly shown in Figs. 1 and 2.

The spring tongues are depending V-shape portion, spring efi'ect.

One edge of one of the spring tongues is formed to provide a cutting edge 28, so that the free end of the cord when finally drawn beneath said spring tongues for holding, maybe readily severed.

WVith use of the improved retaining clips it is apparent that the pressman can readily and conveniently position the cord or cords at any desired points Y lengthwise of the grippers, and that with the clips so positioned the work of securing the cords in With the clips the same tension can be readily and easily seeuredtoall transverse cords in use, and considerable time may thus be saved. Furformed with a to increase the thermore itis apparent that even with the cords wrapped about the grippers the clips may be adjusted longitudinally of the grippers for someslight-distance without materially-afiecting the cord connection This is a decided advantage, which is practically impossible under the customary method of securing the cords, in place.

Another and important function of the cord-retaining clips is that they permit the ready application and securing in position of the cardboard or paper strips usually employed in blocking out, as blocking out the actuating levers of numbering heads when necessary. These blocki forms, and' that changes may ing-out strips, as 30, have usually been glued or similarly secured to the underside of the grippers, but with the improved cord retaining clip, such blocking-out strips may be secured between the plate 19 and the lower surface gripper, the clip being applied from the relatively outer edge of the gripper, as shown in Fig. 6. Obviously, any number of such blocking-out strips may be applied to the gripper, and in any relative positions.

that the invention may be embodied in other be made n the particular form, which has been dofor example in 'on a plane above the plate.
