A TTOR/VEYS JOSEPH LAWRENCE ORR, OF'LYNCHBURG, VIRGIE'LA.
LOCK-BLOCK FOR PAPER ROLLS.
Specification of Letters Patent.
Patented Nov. 14, 1911.
Application filed April 18, 1910. Serial No. 556,154. 1
Toall whom it may concern:
Be it known that I, Josarn LAWRENCE ORR, a citizen of the United States, and a resident of Lynchburg, in the county of Campbell and State of Virginia, have made certain new and useful Improvements in Lock-Blocks for Paper Rolls, of which the following is a specification.
This invention is an improvement in plugs or brushes for use in paper rolls being in the nature of a lock block which when inserted in the end of the paper roll will be locked therein from accidental displacement and will remain in position until the roll of paper has been used up.
The invention conslsts in certain novel constructions, and combinations of parts as will be hereinafter described and claimed.
In the drawing-Figure 1 is a longitudinal section of a roll of paper with two of my plugs applied as in use; Fig. 2 is a detail side view of one of the plugs; Fig. 3 is an elevation of the inner end of one of the plugs; Fig. 4 is a detail section of a part of the plug with the locking pawl in place; Fig. 5 is a detail perspective view of one of the pawls.
By my invention Iseek to provide in connection with a plug' adapted to be inserted in the end of a paper roll, means for looking the said plug in place so it will not drop out while the paper roll is being handled or is in use. The plugs A may be of wood and of the form shown or any other suitable form and are provided with the axial holes B to receive a rod. The plug tapers toward its inner end and on the plug at diametrically opposite points I secure pawls C. Each of these pawls comprises a body portion C whose free end C is sprung slightly away from the body of the plug and is serrated or toothed as best shown in Fig. 2, in order to bite into the paper of the roll, and the pawl also has an end wing C which is at an angle to the body portion C, and is lapped along the end of the plug as shown in Flgs. 1, 3 and 4 of the drawing. It is preferred to employ this end wing C because thereby I provide for fastening the pawl both to the end and to the side of the plug, thus increasing the security of the connection, and it will be understood that in some cases the end'wing might be omitted without departing from some of the principles of my invention, although the said end wing enables me to secure a firmer connection between the pawl and the plug and to arrange the devices for securing the pawl in such manner that those fastening the pawl to the side of the plug will not be interfered with by those which fasten the pawl to the end of the plug. In the construction shown I employ staples D for securing the body portion 0 of the pawl to the side of the plug near the end of the pawl and plug, and nails or tacks E for securing the end wings C to the end of the plug, the nails E as they are driven into the-plug passing between the arms of the st le securing the pawl thus avoiding any Interference between the fastenings.
It will be noticed that the pawls are so arranged that they will not interfere with the introduction of the plugs and will when the plugs are once in place'lock the same firmly from displacement.
It will be noticed that the plug is tapered atits inner end and that the pawls are arranged alongside the tapered portion, being secured at one end to the plug at the smaller end of the latter and extending thence toward the outer or larger end of the plug and sprung outwardly therefrom.
The. construction is simple, inexpensive and efficiently serves the purpose for which it is designed.
I claim: I
A look block or plug for paper rolls provided on its outer side with pawls having body portions, and lateral wings at the ends thereof, the endwings being lapped against Y JOSEPH LAWRENCE ORR.
