JAMES F. CLEGG, OF ELIZABETH, NEW JERSEY.
BOLT-LOCKING DEV ICE.
SPECIFICATION forming part of Letters Patent No. 733,541, dated July 14, 1903.
Application filed October 16,1902. Serial No. 127,590- (No model.)
To all whom it may concern:
Be it known that I, JAMES FREDERICK OLEGG, a subject of the King of Great Britain, residing at Elizabeth, county of Union, State of New Jersey, have invented a new and useful Bolt-Locking Device, of which the following is a specification.
In structural-steel work, as in the erection of modern buildings, construction of bridges, and building of ships, the steel beams, girders, or other parts already punched for the reception of rivets are assembled and temporarily held in position by bolts and nuts,which are removed by the riveters. There are objections to this mode of working,among which may be mentioned the following: The apertures in the two overlying pieces are not always perfectly concentric, and in driving in the bolt the thread is frequently injured,makingitdifficult to apply the nut. Unscrewing of the nutby the riveters takes an undue amount of time and is, moreover,frequently rendered somewhat difficult by such injury to the boltthread. My invention is designed to remove these objections and facilitate the convenience and rapidity with which work of this class may be done. To this end I employ for temporarily securing the elements of the structure an unthreaded bolt having in it a slot or groove to receive a curved wedge,which may by a stroke of the hammer be driven into place to firmly bind the parts together and the smaller end of which by reason of the curvature is always readily accessible, so that the wedge may be displaced by a stroke of the hammer and the bolt withdrawnfor --&c., in steel constructional work comprising substitution of a rivet. A device of this character is particularly useful in those locations, such as in angles of the work, where it would be difficult or inconvenient either to unscrew a nut or drive out a straight wedge.
In the accompanying drawings, Figure l is an illustrative perspective view of an application of my device. Figs. 2 and 3 are views, respectively taken at right angles to each other, of one form of my improved device. Fig. 4 is a view of a bolt having a groove or wedge-socket in its side; Fig. 5, an end view of a curved wedge applicable thereto; Fig. 6, a view showing such a bolt and wedge assembled, and Figs. 7 and 8 are views at right angles to each other of a modified form of bolt made by bending and forging an iron rod.
Referring to Figs. 2 and 3, the headed bolt a is formed with an elongated longitudinal slot 1), in which works a curved or segmental wedge c. The application of such a device and its mode of use are apparent. The curved upper and lower edge of the wedge are arcs of rather long radius, and each is less than a semicircle, so that when the wedge is first inserted, as shown by full lines in Fig. 3, its larger end is separated a considerable distance from the beam and a blow may easily be imparted by a hammer moving in'a diagonal direction relative to the bolt. Similarly, when the wedge is fully inserted, as shown by dotted lines in Fig. 3, it may be displaced by a hammer moving in a diagonal direction. These results are obtained by making the working or effective part of the wedge curved from end to end in the manner specifiecl.
In Fig. 4 the seat of the curved wedge is formed by a recess d in the side of the bolt, the wall 6 of which nearest the end of the bolt is undercut to receive and retain the correspondingly shaped segmental wedge f. (Shown in Fig. 5.) These two parts assembled are shown in Fig. 6.
Figs. 7 and 8 show alongitudinally-slotted bolt g, having a head h, formed'by bending, forging, and welding a piece of rod-iron. It receives and cooperates with the segmental wedge c.
I claim as my invention--- 7 A device for temporarily securing beams,
a bolt having a longitudinally-disposed elongated wedge seat or socket, and a wedge working therein which is curved on opposite sides from endto end of its working portion in arcs less than semicircles, whereby a single blow directed diagonally relative to the axis of the bolt will drive the wedge home, or dislodge it.
In testimony whereof I have hereunto sub scribed my name.
JAMES F. OLEGG.
