TURNBUCKLE Filed Dec. 27. 1929 2 Sheets-Sheet 2 Inventor Attorney Patented Jan. 5, 1932 ALEJANDRO CANTU', OF PONTIAC, MICHIGAN TURNBUCKLE Application filed December 27,1929. Serial No. 416,925.
This invention relates to turn buckles and particularly to devices of this character which are to be used in the construction of aircrafts but it is to be understood that a turn-buckle constructed in accordance with thisinvention may be used for any purpose for which the same is found adapted.
An important object of the invention, is to provide, in a manner'as hereinafter set forth,
a turn buckle of the aforementioned character which includes a novel construction of pins and a locking means mounted on the turnbuckle and 'en 'ageable with said pins in a manner to absolutely prevent the accidental displacement thereof due to wear, vibration or from any other cause.
Other objects of the invention are to provide a turnbuckle of the aforementioned character which will be simple in construction, strong, durable, efficient in its use and which may be manufactured at low cost.
The foregoing and other objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompa-nying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a view in front elevation of a turnbuckle constructed in accordance with this invention, and the special tool which I have provided for mounting the locking means in position thereon being shown.
Figure 2 is a view in side elevation thereof.
Figure 3 is a view in vertical longitudinal section taken substantially on the line 33 of Figure 2. V
Figure 4 is a view in horizontal section through the threaded portion of the turn buckle rod showing the manner of mounting the special tool thereon.
Figure 5 is a detail view in perspective of the turnbuckle with the pins and rod removed therefrom.
Figure 6 is adetail view in perspective of the substantially U-shaped pin latching or locking element.
Figure 7 is an enlarged detail view in perspective of the pin.
Figure 8 is a detail view in perspective of the lock nut which is threaded on the rod for engagement with the turnbuckle.
Referring to the drawings in detail, the reference character 1 designates an elongated rod which, in aircraft construction, may be a 5i strut rod or wire having the threaded end portion 2 upon which is threadedly engaged the tubular sleeve 3 which terminates in the spaced parallel, opposed furcations 4 the upper end portions of which are provided with the horizontally aligned eyes 5 through which extends transversely the connecting pin 6. The pin 6 isprovided, on one end, with an enlarged head 7 to limit the inward movement of said pin through the eyes 5. Adjacent the head 7 and the opposite ends thereof, said pin is further provided with the annular grooves or channels 8 which are disposed on the outer sides of the furcations 4 when the pin is in position. '70
A substantially U-shaped metallic keeper 9 is slidably mounted on the rod 1 through the medium of the apertured connecting portion 10 which encircles said rod in a manner to permit longitudinal movement of the keeper thereon. The free end portions of the legs 11 of the keeper 9' are provided with the aligned openings 12 for thepassage of the pin 6, as elearlyillustrated in Figures 1 and 3 of the drawings. Adjacent their point of connectionwith the tubular sleeve 3 the furcations 4 are curved outwardly to provide a shoulder or abutment. An expansible coil spring 13 encircles the sleeve 3 and the adj acent portion of the rod 1 and has one end impinged on the curved inner portions of the furcations 4 and the other end impinged against the connecting portion 10 of the keeper 9 for yieldingly urging said keeper inwardly on the rod. A look nut 14 is threaded on the rod 1 for engagement with the inner end of the sleeve 3 for locking said sleeve in adjusted position on said rod. As clearly illustrated in Figure 3 of the drawings, the walls of the openings 12 of the keeper 9 are adapted to seat in'the channels or grooves 8 of the pin 6, and said pin is thus securely held in position in accidental displacement by reason of the coil spring 13 forcing said keeper longitudinally with respect to the pin and the which are resiliently connected together at one end through the medium of the loop 16.
Intermediate their ends, the inner faces of the arms 15 are provided with the opposed co-acting threaded recesses 17 adapted for threaded engagement with the threaded por tion 2 of the rod 1. The inner sides of the arms 15 are flat. The special tool is mounted in position on the rod by spreading the arms apart and sliding the same thereover until said rod is disposed in the recess 17 and the tool will be maintained thereon by its inherent resiliency. In this position the opposite ends of the arms may be used in the manner of levers for the purpose of rotating the tool on the rod for engaging the keeper 9 and forcing the same outwardly against the tension of the coil spring 13, as will be apparent. It will thus be seen that I have provided a turnbuckle wherein the chance of the pin becoming lost or displaced accidentally therefrom is reduced to a minimum.
It is believed that the many advantages of a turnbuckle constructed in accordance with this invention will be readily understood, and
channels of the pin for preventing longi tudinal movement of said pin through the end portions of the keeper encircling the pin and seated in the channels therein for preventing longitudinal movement of said pin in theopening, and an expansible coil spring encircling the sleeve and the adjacent portion of the rod and having one end impinged against the furcations of said sleeve and the opposite end impinged with the connecting portion of the keeper, for yieldingly urging said keeper inwardly with respect to the rod.
In testimony whereof I afiix my signature.
, ALEJANDRO CANTU.
