IMPROVEMENT IN SHUTTER-FASTENINGS.

Specification forming part of Letters Patent No. 144,126, dated October 9.8, 1873; application filed September 24, 1873,

To all whom it may concern:

Be it known that I, JULIUs PARKER, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Blind-Fastening; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a sectional side view as arranged in the blind or shutter; Fig. 2, a front view of the secnring-collar; and in Fig. 3, a section of the same on line w w.

This invention relates to an improvement in that class of blind or shutter fastenings which extend through the shutter from one side to the other, so that the hook upon one side may be operated from the opposite side; and it consists in a barrel, longitudinally through which the latch or lever extends, the said barrel being cast with a head or collar at one end to rest upon the surface of the shutter, and provided at the other end with several teeth or serrations, and combined with a collar, having a single screw-thread cast upon its inner edge, to pass onto that end of the barrel, so as to be turned onto the barrel through the said teeth hard against the other surface of the shutter, and thus firmly hold the fastening in place without the necessity of other security.

A is the barrel, through which the lever B passes in the usual manner. The barrel A is formed with a flange or head, C, upon one end, so as to rest upon the surface of the blind or shutter D, as seen in Fig. 1. At the other end of the barrel several teeth or serrations, a, are formed, the barrel being of sufficient length to extend a short distance through the blind. E is a collar, the internal diameter of which corresponds to the diameter of the barrel. The inner edge is formed into a single screw-thread, as denoted in Figs. 2 and 3, so that when set onto the end of the barrel and turned around, the thread of the collar will work its way through the teeth at until it comes against the shutter, and, turning hard down, holds the fastener firmly in its position.

This collar is easily cast, as are the teeth a, on the barrel, so that no labor is required to prepare the means of fastening, and the securing of the fastening to the blind is much more readily done than in any of the known constructions.

I do not wish to be understood as broadly claiming arranging the fastening for shutters in a cylindrical case formed with a threaded collar, as such I am aware is not new.

I claim as my invention- The barrel A, when cast with the flange C upon one end, and the teeth a upon the other end, and inclosing the lever B, in combination with the collar E,having a single screw-thread cast upon its inner edge, so as to engage the teeth a, substantially as described.
