Specification of Letters Patent.

Application filed November 14, 1905. Serial No. 287,266.
T0 all when@ t rib/.Ly concern:
Be it known that I, FRANK UHL, a citizen of the United States, and a resident of South Sharon, in the county of Mercer,in the State of Pennsylvania, have invented a new and useful Construction of Nut-Lock, of which the following is a specification.
This invention relates generally to nutlocks, and more particularly to an improved construction of nuts carrying with it means for engaging the thread of the bolt and holding the nut securely locked thereon.
The object of the invention is to provide a simple and efficient means for accomplishing locking operation and one which can be quickly and easily released by one acquainted with its construction.
IVith these objects in view my invention consists, essentially, in making the nut in two parts, one of said parts being adapted to turn upon the other and carrying a knife adapted to be projected through an opening in the rst-mentioned part for the purpose of engaging the thread of the bolt, the movable part carrying a spring-actuated locking-bolt which is adapted to engage a recess in the stationary portion of the nut after the movable portion has been turned a denite amount, thereby securely locking the parts against return movement.
The invention consists also in certain details of construction hereinafter fully described, and pointed out in the claims.
In the drawings forming a part of this specification, Figure l is a perspective view of a nut constructed in accordance with my invention, one side thereof being broken away to disclose the knife or blade. Fig. 2 is a top plan view of thelower section of the nut. Fig. 3 is a vertical sectional view taken througi the complete nut and showing the same in a locked condition. Fig. 4 is an inverted plan view of the upper section of the nut. Fig. 5 is a sectional view taken through said upper section, and Fig. 6 is a detailed perspective view of the knife.
In constructing a nut-lock in accordance with my invention I employ a lower section A and an upper section B. The lower section A is threaded throughout its entire length, as shown at A but the annular upwardly-proj ecting portion A2 the upper section B is fitted thereon, and the upper end of the annular portion A2 is headed down, so as to prevent the upper section B Working off. This upper section B, however,
has a smooth exterior, and
l is free to turn upon the annular upwardly- 'l projecting portion of the lower section A. 1 I have shown my invention applied to a a hexagonal-shaped nut; but it will be underi stood that my invention can be used equally l as well upon a four-sided nut or an eightsided nut, if so desired.
The upper section B is formed with a cam- 5 shaped recess B', which communicates with i its central opening, and located in this caml, shaped recess is the cam knife or blade O, i having a pivot O', which fits into the depres- B2, as most clearly shown in Fig. 5. An
l sion il opening A3 is produced in the upwardly-projeted annular portion A2, and this opening is of a size to receive the free end of the knife or blade O, and said blade is so shaped that 'l the corner A4 of the opening A3 engages or is engaged by the end of the knife or blade when the upper section of the nut is turned and the edge of said knife or blade is projected through the opening A3 and bites into the thread of the bolt. The upper section B is also provided with a socket D, in which is arranged a locking-bolt E, forced downwardly by means of a spring F, which surrounds the upper portion of the bolt E, said bolt being adapted to be projected into a re- 1 cess G, produced in the upper-face of the lower section A when the upper section has been turned sufficiently to bring the locking-bolt over the recess G, and also the locking-bolt is brought into alinement with said recess, the spring acting to force the said bolt into the recess, and by this means the upper and against any further movement one upon the other. A lateral opening G is provided, communicating with the recess G, through which a pin may be inserted for the purpose of forcing the bolt E upwardly whenever it is desired to disengage the locking-bolt from the lower section of the nut. The socket D extends entirely through the upper section B, but at its upper end is of less diameter than at its lower end, and this upper end is normally closed by means of a screw-plug D.
In constructing the nut the upper sectioa carrying the knife and spring-actuated bolt are arranged upon the lower section of the nut, and tlhe upper end of the annular portion A2 is headed down in such a manner as to sei curely connect the two sections together, but l still permit the upper section to turn upon the l, lower section. In Operation the compound nut is screwed lower sections of the nut are securely locked IOO IOS
ILO
upon the bolt to the desired point, and while the lower section is securely held the upper or outer section is given the necessary turn for the purpose of projecting the edge of the knife or blade into the thread of the bolt and simultaneously locking the upper or lower sections yagainst any further movement.
It will readily be understood that a nut lock as herein described cannot possibly turn upon the thread, and in order to remove it it is necessary to first release the upper or outer section of the nut, so that the knife or blade can be withdrawn from the thread, and this releasing operation can be accomplished by insertin a pin in the lateral opening G, forcing the lgockingbolt E upwardly, and then giving the upper or outer section a forward turn, so as to withdraw the knife or blade.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is.-
1. A nutlock comprising a lower and upper section, the upper section being adapted to turn upon the lower section and carrying a knife adapted to be projected through an opening in the lower section and a spring-actuated locking-bolt carried also by the upper section for engagement with the lower section as specified.
2. A nut-lock comprising a lower section having an upwardly-projecting annular portion the interior of said annular portion being threaded, said annular portion having an opening at one side thereof, an upper section having a recess and a socket produced therein, a knife arranged in the recess and adapted to be projected through the opening in the annular portion of the lower section and a spring-actuated bolt arranged in the socket and adapted to engage an opening in the lower section of the nut, as set forth.
3. A nut-lock comprising a lower section having an upwardly-projecting annular p0rtion said annular portion having an opening in one side thereof, said lower section also having a recess, said recess having a lateral opening communicating therewith, the up er section of the nut having a recess andJ a socket, a knife arranged in the recess and adapted to be projected through the opening in the annular portion of the lower section of the nut and a spring-actuated bolt arranged in the socket and adapted to engage the recess in the lower section of the nut when the upper section is turned upon the lower section to project the knife through the opening in the annular portion in the lower section.
