1 Claim.
The present invention relates to new and useful improvements of structural refinements in socket wrenches, and the principal object of the invention is to facilitate convenient and expeditious tightening or loosening of bolts, nuts, etc., by impact resulting from inertia of a quickly rotating, suddenly stopped body.
This object is achieved by the provision of a wrench which includes an elongated member having a screw-threaded portion and adapted at its ends to selectively receive wrench sockets of different sizes, while a rotatable actuating member is movable longitudinally on the screw-threaded portion of the first named member and is adapted to abut stops at the opposite'ends of the screwthreaded portion, so as to suddenly arrest rotation of the actuating member and transmit the resultant impact to the work.
Some of the advantages of the invention reside in its simplicity of construction, in its efficient and expeditious operation, and in its adaptability to economical manufacture.
With the above more important objects and features in view, and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:
Figure 1 is a side elevational view of the invention;
Figure 2 is a longitudinal sectional view thereof;
Figure 3 is a transverse sectional view, taken substantially in the plane of the line 3-3 of Figure 1; and
Figure 4 is a transverse sectional view, taken substantially in the plane of the line 4-4 of Figlife 2.
Like characters of reference are employed to designate like parts in the specification and throughout the several views.
Referring now to the accompanying drawings in detail, the invention consists of a socket wrench which is designated generally by the reference character Ill and embodie in its construction an elongated body l2 including a screwthreaded intermediate portion I4, a pair of cylindrical end portions I5 terminating at the outer ends thereof in polygonal adaptors I8 to which conventional wrench sockets of different sizes may be selectively and interchangeably applied.
A pair of tubular sleeves 28 are rotatably mounted on the end portions l6 and are sustained in position thereon by suitable caps or collars 30 which are present on the adaptors I8, as shown. Needless to say, the sleeves 28 may be utilized as convenient handles for the entire device while the body 12 and wheel 34 are in rotation.
The wrench actuating member comprises a screw-threaded hub 32 which operatively engages the screw-threaded portion M of the body l2 and has secured thereto a hand wheel 34 by means of a set screw 36.
As the hub 32 rotates it travels, of course, longitudinally on the screw-threaded portion l4, and it is to be noted that the hub 32 is recessed at the opposite ends or sides thereof so as to afford fiat faces 38 which are disposed in parallel planes relative to the longitudinal axis of the body l2 and relative to the side faces of the flat blocks 24.
Accordingly, when the invention is placed in use and sockets are applied to either or both of the adaptors l8, rotation of the hand wheel 34 and of the associated hub 32 will cause the hub to travel longitudinally on the screw-threaded portion l 4 until one of the flat faces 38 of the hub abuts one of the stop blocks and the inertia impact is transmitted to the work for either tightening, or loosening, the same, as the case may be.
It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is deeme unnecessary.
While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
Having described the invention, what is claimed as new is:
A wrench comprising an elongated body having a pair of end portions and a screw-threaded intermediate portion, a pair of wrench socket receiving adapters provided at the outer ends of said end portions, a pair of stop blocks provided on the end portions adjacent the respective oppo- U site ends of the screw-threaded intermediate portion, a pair of sleeves rotatable on the respective end portions of the body between said blocks and said adaptors, and a screw-threaded actuating member rotatably mounted on said intermediate portion and movable longitudinally thereon, said member being provided at opposite sides thereof with flat faces adapted to abut and impact the respective stop blocks at the opposite ends of the travel of said member on said body.
