LOOSE-SHEET HOLDER.

SPECIFICATION forming part of Letters Patent No. 766,364, dated August 2, 1904.

Application filed October 5,1903 Serial No. 175,732. (No model.)

To {L/Z 1071,0111, it m/u won/(207w..-

Be it known that I, ALBERT Lnwsox, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in LooseSheet Holders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification. a

My invention relates to a device for receiving and holding loose sheets of paper, it being pz'irticularly intended for use in assembling and confining tissue copies of railrozul-waybills, but is of utility in the binding of any loose sheets.

The device is of a description that renders it adaptable for use either as a temporary binder or in binding loose sheets into permanent condition.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective view of my loosesheet holder. Fig. II is a longitudinalsection taken on line II II, Fig. I, with the bed-block of the holder in elevated position. Fig. III is a section taken on line III III, Fig. I. Fig. IV is a top view of the central portion of the holder bed-block and the clamp therein with one of the paper-receiving prongs and the post therein shown in section. Fig. V is a perspective view of a shield for application to the prongs of the holder for the protection of its user when the holder is being handled. Fig. VI is a top view of the paper-confining clutch used to hold the loose sheets assembled on the prongs of the holder. Fig. VII is a longitudinal section taken on line VII VII, Fig. VI, through the paper-confining clutch.

1 designates the base of my loose-sheet holder, upon the rear portion of which is mounted a bed-block 2, that is connected to the base by hinges 3, so that it may be swung into a vertical position, as seen in Fig. II.

4 designates supporting-strips extending transversely of the bed-block 2 and suitably secured to said block. Mounted on these supporting-strips is a fixed clamp-bar 5, that is rigidly secured to said strips by rivets 6 or other suitable means.

7 is a loose clamp-bar seated on the supporting-strips I and extending in a line parallel with the fixed clamp-bar 5,thereby placing the two clamp-lmrs in opposition to each other for clamping action. Each of the clamp-bars is provided at intervals with notches, which when brought together form apertures, in which prongs to be hereinafter mentioned are held in upright positions. Through the medium of the supporting-strips 4: the

clampbars

5 and 7 are upheld at an elevation from the bed-block 2 fora purpose that will hereinafter be made clear.

8 is an eccentric, having a handle 9 and swingingly mounted upon the bed-block Qby means of a pivot-stud 10. This eccentric is designed to act as a pressure member to carry the loose clamp-bar 7, against which it bears, to the fixed clamp-bar 5 for clamping action.

11 designates the loose sheetreceiving prongs that are held between the clamp-

bars

5 and 7. These prongs are provided at their upper ends with points 12 and have opes lower ends, as seen in Fig. II. The prong receive serrated wires 13, that are provided with heads lei, which occupy positions exterior of the prongs. \Vhen the prongs are seated between the clamp-bars with the wires 13 within them, the heads of the wires occupy positions beneath the clamp-bars, as seen in Fig. II, for which purpose the clamp-bars are elevated by the supporting-strips I, as explained.

In Fig. II, I have shown my sheet-holder in the condition in which it is used in assembling sheets of paper thereon and in which A designates a cover-board of a binder which is applied to the prongs 11, and B designates sheets of paper assembled on the holder above said cover-board.

15 designates. a clutch-bar which is provided with a series of apertures 16, corre sponding in number to the number of sheetreceiving prongs 11. Hounted on the clutchbar are spring-fingers 17, each having one end fixed to the bar and having its opposite end free and notched to engage the sheet-re- 1 dled.

with the prongs, which are necessarily sharp ceiving prongs, as shown by dotted lines, Fig.

VII, to hold the clutch-bar in engagement with said prongs. The clutch, consisting of the parts described, is designed to be applied to the prongs 11 after a quantity of loose sheets have been assembled on the holder, and when so applied it serves to hold the sheets in place while the holder is being han- 18 designates a shield, preferably of sheet metal, and consisting of aplate 19, which carries a hood 20 and has at each of its ends a cone 21. This shield is designed for application to the points of the prongs 11, as seen in Figs. II and V, when the loose-sheet holder is being handled by the user at any other time than during the process of assembling sheets of paper thereon. The shield serves as a protection for the points of the prongs and as a guard to prevent injury to the person using or handling the holder by coming in contact to facilitate the operation of assembling the sheets of paper thereon.

As hereinbefore stated, my holder is of utility both as a temporary binder and as a means for assembling loose sheets of paper for permanent binding. In its use as a temporary binder the parts of the holder are utilized in the manner described, the sheets of paper being confined upon the prongs and the points of the prongs protected, as stated. Whenever it is desired to examine the sheets of paper, the bed-block 2 is swung into the vertical position, (seen in Fig. II,) thereby throwing the prongs into a horizontal position. WV hen this has been done, the sheets are held firmly, the same as if in a bound book, in open condition and may be turned and examined with facility and returned to the original position after examination without disturbing any of the members of the holder.

When it is desired to assemble additional sheets of paper on the holder, it is only necessary to remove the shield 18. and the paperconfining clutch. v

Where the holder is used as a medium for assembling sheets of paper to be bound in permanent form, the same operation as that described in assembling the sheets on the holder is carried out, and after the required number of sheets have been assembled a coverboard corresponding to that designated as A is passed over the sheet-receiving prongs, so]

that the sheets will be confined between two covers. The loose clamp-bar 7 is then released and the prongs 11 are drawn out of the assembled sheets of paper, therebyieaving the wires 13 therein. The wires may then be secured by any suitable means to the covers to complete the back.

I claim as my invention 1. In a loose-sheet holder, the combination of a base, a bed-block hinged to said base, and tubular sheet-receiving prongs carried by said bed-block, said prongs being removably held to said bed-block and open at their lower ends to receive binding-wires, substantially as described.

2. In a loose-sheet holder, the combination of a base, a bed-block hinged to said base, tubular sheet-receiving prongs surmounting said bed-block, and a clamp seated on said bedblock and confining said prongs, said prongs being removably held to said bed-block and open at their lower ends to receive bindingwires, substantially as described.

3. In a loose-sheet holder, the combination of-a bed-block, a clamp surmounting said bedblock and elevated therefrom, tubular prongs confined Joy said clamp, and headed bindingwires positioned in said prongs, said prongs being removably held within said clamp and open at their lower ends to receive said binding-wires, substantially as described.

4. In a loose-sheet holder, the combination of a base, a bed-block hinged to said base, tubular sheet-receiving prongs surmounting said bed-block, and a clutch applied to said prongs to confine the sheets assembled thereon, said prongs being removably held to said bedblock and open at their lower ends to receive binding-wires, substantially as described.

5. In a loose-sheet holder, the combination of a base, a bed-block hinged to said base, sheet-receiving prongs surmounting said bedblock, a clutch applied to said prongs to confine the sheets assembled thereon, and 'a shield fitting over the points of said prongs, substantially as described.

6. In a loose-sheet holder, the combination of a base, a bed-block hinged to said base, supporting-strips mounted on said bed-block, a stationary clamp-bar seated on said supporting-strips, a loose clamp-bar seated on said supporting-strips for movement to said stationary clamp-bar, sheet-receiving and binding-wire-holding prongs confined between said clamp-bars, and an eccentric for moving said loose clamp-bar to said stationary clamp-bar, substantially as described.
