BOLT-CASE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed March 19, 1909. Serial No. 484,445.

T 0 all whom it may concern:

Be it known that I, RICHARD W. HUB- BARD, citizen of the United States, residing at Ashtabula, in the county of Ashtabula and State of Ohio, have invented new and useful Improvements in Bolt-Cases, of which the following is a specification.

My present invention relates to cases for bolts; and it seeks to provide a bent metal bolt case, susceptible of being quickly and easily made, without the employment of expensive machinery, and one possessed of great stiffness and strength and adapted to be embellished so as to present a highly ornamental appearance.

The invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a perspective view of a bolt case constructed in accordance with my invention and designed for use in combination with a spring-backed bolt. Fig. 2 is a vertical section, taken through the barrel of the case. Fig. 3 is a rear elevation of the same. Fig. 3 is a view showing the pattern from which the bolt case shown in Figs. 1 to 3 is formed. Fig. 4 is a perspective View of a modified bolt case embodying my invention. Fig. 5 is a longitudinal section through the barrel of the same. Fig. 6 is a longitudinal-central section of the embodiment illustrated in Fig. 4. Fig. 7 is a perspective View of a bolt-keeper constructed in accordance with my invention.

Similar letters of reference designate corresponding parts in Figs. 1 to 3 of the drawings.

My novel bolt case is formed by bending a single piece of sheet-metal, of suitable stiffness and strength and of the configuration shown in Fig. 3 and it comprises a barrel A, of circular or other suitable form in crosssection, in which is a longitudinal slot a for the play of the finger-piece usually provided on a slidable bolt, adjacent loops B at the base of the said barrel, flanges C arranged in a common plane and extending in opposite directions from the said loops B, and a rear end wall D. The loops B lend stiffness and strength to the case throughout the length thereof, and in combination with the rear end wall D render the case quite as stiff, strong and durable as a castmetal case. The rear end wall D is formed in the peculiar manner shown in Fig. 3 that is to say, it is made up of four sectorshaped portions Z) Figs. 3 and 3* which are pressed or otherwise connected together and consequently support and contribute to the strength of each other with the result that the end wall is equally as strong and durable as a wall cast integral with the barrel.

The case disclosed in Figs. 4 to 6 is formed of a single piece of suitable sheet-metal bent into shape. It differs, however, from the case shown in Figs. 1 to 3 in that both ends of its barrel A are open, this in order to enable a bolt to play in opposite directions through said ends. It will be noticed, however, that the embodiment shown in i to 6 is like that of Figs. 1 to 3 in that it comprises in addition to the barrel A adjacent loops B at the base of the barrel, and flanges C arranged in a common plane and extending in opposite directions from said loops.

In Fig. 7 I have shown a bolt keeper constructed in accordance with my invention. This latter is made of a single piece of sheetmetal, bent into shape, and comprises a barrel A loops B at the base thereof, and flanges C arranged in a common plane and extending in opposite directions from the said loops. It will also be observed by reference to Fig. 7 that the receiving end of the barrel comprised in the bolt keeper is slightly flared or enlarged to facilitate entry of a bolt.

In all of the several embodiments of my invention, the flanges are provided with apertures elongated in the direction of the width of the cases. This provision is preferably made in order that the bolt in the case and the keeper may be readily alined before the attaching screws passed through the elongated apertures are driven home to fix the bolt case or keeper as the case may be.

It will be readily gathered from the foregoing that my novel sheet-metal cases may be cheaply produced, and that they are not only as strong and durable as a cast-metal case, but are adapted to be made highly ornamental in appearance.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

A device for the purpose described, formed of a single piece of bent sheet-metal, and

comprising a barrel, adjacent loops at the my hand in presence of two subscribing Witbase of the barrel, flanges arranged 1n a messes.

common plane and extendin in opposite directions from the loops, and sector-shaped RICHARD U portions grouped together and forming the X/Vitnesses:

rear end Wall of the barrel. J NO. P. HUBBARD,
