EXPANSION-BOLT.
SPECIFICATION forming part of Letters Patent No. 688,756, dated December 10, 1901. Application filed May 24,1900. Renewed November 1, 1901. sari-9,1110. 80,817. (No model.)
T (tZZ whom it may concern:
Be it known that I, JACOB W. TRIPP, acitizen of the United States, and a resident; of the city, county, and State of New York, have invented a new and useful Expansion-Bolt, of which the following is a specification.
My invention relates to bolts for driving into brick or stone work especially and which by certain formation and mechanism become barbed to prevent a too-ready withdrawal; and it consists of a bolt comprising three parts which united constitute a whole. The first part consists of a tubular shell or casing having a threaded interior at one end, into which is threaded a drive-screw having a bolt-head exteriorly. At the other end of the shell is inserted or otherwise placed a block of certain and suitable shape to fill up the bore in the shell. These three parts compose the bolt complete. The shell is formed with longitudinal slots toward one end, and the expansion-block is formed with lateral flanges extending into the slots of the shell. The interior end of the drive-screwimpinges against the heel or inner end of the expansion-block and when turneddrives it forward, effect-uating the creation of barbs, all as hereinafter more fully described, and pointed out in the claims, reference being had to the accompanying drawings, in which-' Figure 1 represents in elevation the bolt complete ready for insertion in a wall. Fig. 2 represents in elevation the penetrating or expansive end of the bolt. Fig. 3 represents in elevation the bolt complete as expanded, the expansion-block forced outward. The dotted lines within Figs. 1, 2, and 3 indicate the bore of the shell interior. Fig. 4 represents in elevation the end shown in Fig. 2, but expanded. Fig. orepresents in elevation the expansion-block alone. Fig. 6 represents in elevation the inner end or heel of the expansion-block. Fig. '7 is a longitudinal section of the shell (casing or bushing) alone. Fig. 8 represents in elevation an end face analogous to that of Fig. 2 modified into a rectangular form. Fig. 9 shows the end of Fig. 8 as expanded. Fig. 10 shows in elevation a modification in the barb end of the shell.
In the drawings, A indicates the shell or It is formed with a hollow centerB,
casing.
threaded part way, asat C, and closing nearly together, as at D, after the manner shown in Fig. 7, so that at one end the tube nearly closes up with a gradual incline, rendering the metal thicker at that end. At that same end also lateral slots, splits, or longitudinal openings are formed, crossing the end of the shell and extending a suitable distance along toward the midwayof the length of the shell, as shown at E, Fig. 7. At that same end also the outside of the shell is indented, grooved, or molded after the manner shown at F, Fig. 1, the surface of which indentations is inclined.
G indicates a block of metal, shaped as shown in Figs. 5 and 6, with lateral flanges H and I, and having its surface formed to fit the hollow of the shell, and toward one end the rounded parts incliningtoward the end, after the manner of a wedge, to fit the inner inclined surface of the shell at that end when in the shell, the flanges of the block set into the slot E or opening of the shell, as shown in Figs. 1, 2, and 8. This described end of the shell in which the block Gris fitted is the end to enter a wall or similar place where destined for use. The block G at one end is wedge-shaped, and the surface interior of the bore in the shell at the same end is formed to fit it at the same angle.
K indicates the bolt proper or drive-screw. It is of the common form and having the usual bolt-head, as at L. In use the inner end of the bolt impinges against the heel of the expansion-block and as it is screwed inward forces outwardly the wedge-shaped block, which, as the meeting inner face of the shell fits and is shaped closely thereto, forces the shell approximately into the condition shown in Figs. 3, l, and 9, and as that threaded midway, part way, and toward and 1. A combination expansion-bolt of three parts-to wit: first, a tubular shell interiorly at the expansion end formed with two oppositely-arranged slotted openings longitudinally; second, an expansion block or plug inserted or otherwise placed within the bore of the non-threaded portion of the shell fitting thereto and formed with two oppositelyarranged lateral flanges fitting into the longitudinal slots of the shell; third, a drivescrew or bolt fitted into the threaded portion of the shell with its interior end impinging against the inner end of the expansion block or plug and adapted-to drive outwardly the block whenoperated, essentially as set forth.
2. The hollow shell split longitudinally at one end by lateral openings as slots, the inset forth.
