SPRING LOADED CUE
United States Patent 3858882
A spring loaded pool or billard cue, or the like, is provided which includes an elongated tubular housing and rod slidably mounted in the housing, the rod being biased by a power spring within the housing to a position in which it protrudes out one end of the housing. To load the cue, the rod is pushed back into the housing against the bias of the power spring, and it is locked at any desired position with respect to the housing by one or more locking washers. These locking washers are resiliently biased to a tilted position to perform their locking function. The rod is released by a trigger mechanism which causes the washers to assume an upright position with respect to the rod.

RELATED PATENT APPLICATION
Application Ser. No. 143,855, filed May 17, 1971, for Clyde E. Fox, et al., now abandoned.
BACKGROUND OF THE INVENTION
The present invention is concerned with the mechanical type of pool or billiard cue, in which a spring loaded rod is released from a tubular housing and caused to strike against the ball as the game is played. The cue, in one of its embodiments, is fabricated to simulate a usual pool or billiard cue, with a trigger handle extending from one side of the cue so as to release the internal rod when a shot is to be made. In a second embodiment, the pool cue is shaped to have a pistol-like configuration, so that "shots" are made by the player actually shooting the pistol.
In both embodiments of the invention, and as will be described, the cue has the feature in that it is inherently simple in its concept, so that it may be made inexpensively, and yet be rugged and capable of trouble-free operation over a long period of time. In addition, the cue constructed in accordance with the concepts of the invention has a feature of an inherently simple trigger mechanism, the trigger mechanism being constructed to permit the actuating rod to be moved back into the supporting housing to any desired position and to achieve any desired compressional force on the power spring. This permits each player to gage the force at which the individual shots are to be made, and constitutes an improvement over the usual prior art construction which depend on a ratchet arrangement with a small number of definite locking positions, as compared with the infinite number of locking positions of the mechanism of the invention, so as to result in less accurate control of the desired force in the prior art arrangements.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a side section of a billiard or pool cue constructed in accordance with one embodiment of the invention; and
FIG. 2 is a side section of a billiard or pool cue constructed in accordance with the concepts of the invention, and representative of a second embodiment whereby the cue itself simulates a pistol.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
At the outset, it should be pointed out that although the structure of the present invention is described as a billiard or pool cue, it will be apparent as the description proceeds that the cue of the invention may be used in a variety of games in which it is desired not only to propel billiard balls as in a game of pool or billiards, but in which any other object is to be propelled.
In the embodiment of FIG. 1, the cue mechanism includes a tubular housing 10 having an elongated configuration and simulating, for example, a usual billiard cue, insofar as its outward appearance is concerned. The housing 10 may be formed of metal, plastic, wood or any other desired material.
A rod or shaft 12 is slidable within the tubular housing 10. The shaft 12 is held in coaxial relationship within the housing by means, for example, of a block 14. The rod 12, likewise, may be composed of metal, plastic, wood or any other suitable material. A power spring 16 is mounted on the rod 12. One end of the spring 16 bears against the forward end of the block 14, and the other end bears against a retainer member 18 mounted on the rod or shaft 12. The power spring 16 serves to bias the rod 12 towards the left in FIG. 1, and to a "fired" position in which the end of the rod 12 protrudes out from the end of the housing 10. A tip assembly 20 is mounted on the extremity of the rod 12, as shown.
In the assembly of FIG. 1, the rod 12 is shown in its "loaded" position, in which it is retracted fully into the housing 10. It is held in that position by means of a series of washers including a first actuator washer 22 which is mounted in the housing 10 coaxially with the rod 12. The washer 22 extends into a slot in the block 14, and its diametrically opposite side supports a trigger handle 24 which extends externally of the housing 10.
A plurality of additional washers 26 are mounted in the housing coaxially with the rod 12, and the latter washers being adjacent the face of the actuator washer 22. The washers 26 are spring biased by a trigger spring 28 which bears against the block 14. The trigger spring 28 resiliently urges the washers 26 against the actuator washer 22, and also biases the washers to the illustrated inclined position in which they lock the rod 12 in its illustrated "loaded" condition within the housing 10.
To actuate the assembly of FIG. 1, the trigger member 24 is pressed down towards the housing 10, and this causes all the washers 22 and 26 to be turned against the pressure of the spring 28 to an upright position with respect to the shaft 12. This permits the shaft 12 to slide freely under the action of the power spring 16 to the left of FIG. 1, and causes the tip assembly 20 to be driven against the object to be propelled by the mechanism.
A buffer spring 30 is mounted on the right-hand end of the rod 12 by means, for example, of a retainer 32. The shock of the rod assembly 12 as it reaches the end of its travel is minimized by the buffer spring.
To reload the mechanism of FIG. 1, it is merely necessary to push the tip 20 towards the end of the housing 10, so that the rod 12 will move back against the pressure of the power spring 16, causing the washers 22 and 26 to assume an upright position as the rod is so pushed. It is clear that the rod may be pushed back into the housing to any desired position, and that upon release, the washers 22 and 26 will immediately lock the rod in that position. This means that the player can set his cue to any desired tension, merely by pushing the rod 12 back into the housing until the desired tension has been attained, and then by releasing the pressure on the tip. Any further movement of the rod 12 is then prevented by the washers 22 and 26, until the trigger mechanism has been actuated by actuation of the trigger member 24.
The embodiment of FIG. 2 is generally similar to the embodiment of FIG. 1, and similar elements have been designated by the same numbers.
In the latter embodiment, a pistol grip 10a is formed on the housing 10, and the trigger member, designated 24a extends from a slot in the housing 10 as an extension of the actuator washer 22a. In the latter embodiment, the block 14 is made integral with the housing 10. The trigger washers 26, as before, bear against the face of the actuator washer 22a, and all the washers are biased to their inclined position by a spring 28a which, in the embodiment of FIG. 2, is a leaf spring, as shown.
The invention provides, therefore, an improved spring loaded cue, which is simple and economical in its construction, and yet which is superior in its operation to the usual prior art device of the same general type.
It should be understood, of course, that although particular embodiments of the invention have been shown and described, modifications may be made. It is intended in the following claims to cover all modifications which come within the spirit and scope of the invention.

In the embodiment of FIG. 1, the cue mechanism includes a tubular housing 10 having an elongated configuration and simulating, for example, a usual billiard cue, insofar as its outward appearance is concerned. The housing 10 may be formed of metal, plastic, wood or any other desired material.
A rod or shaft 12 is slidable within the tubular housing 10. The shaft 12 is held in coaxial relationship within the housing by means, for example, of a block 14. The rod 12, likewise, may be composed of metal, plastic, wood or any other suitable material. A power spring 16 is mounted on the rod 12.
