coMmNnn vI-sn AND JACK.
Application filed June 27,
To all whom it may concern:
Be it known that I, DANIEL P. V1011, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Combined Vises and Jacks, of which the following is a specification.
This invention relates to a combined vise and jack.
The principal object of this invention is to combine a vise and a jack in such a manner that both of these devices will be of equal utility, strong, handy, and simple to operate.
Another object is to produce a device of this character which is readily portable and also cheap .to manufacture.
A further object is to provide means whereby a single bolt serves to secure the operating screw and stationary jaw in the casting, thereby eliminating any unnecessary parts.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a side elevation of my device partly broken away in order to better illustrate the invention,
Fig. 2 is a top plan view of Fig. 1, and
Fig. 3 is an enlarged detail view of the manner of retaining the operating nut against accidental withdrawal.
In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a casting consisting of a longitudinal portion upon which are formed feet 6 and 7 which feet act as rests when the device is used upon a bench or other support in the capacity of a vise. The longitudinal portion is designated by the numeral 8 and is formed with a channel within which a screw 9 is adapted to move.
A head 11 is formed upon the casting, which head is provided with a working face 12. The screw 9 carries a head 13 having a working face 14 and also a pipe gripping element 16. A similar pipe gripping element 17 is formed upon a locking member 18, which locking member is held within the head 11 by a bolt 19. The locking member 1924. Serial No. 722,767.
18 has a V-shaped notch 21 adapted to engage a fin 22 of the nut 23, which nut is threaded upon the screw 9. V A lever 24 is slidably held in an enlarged portion 26 of the nut 23 and it is through the medium of this lever that the nut 23 may be rotated. An offset portion 27 upon the casting 5 serves to protect the fin portion of the nut 23, as best shown in Fig. 1. Rot-atably secured to the end of the screw 9 is a rotatable member 28 held thereon by a setscrew 29.
The structure thus formed may be employed as follows By securing the device to a suitable support such as a work bench and by rotating the lever 24, the nut 23. will be caused to move the screw 9, depending upon the direction of rotation of the lever 24 together with its associated nut. Asthis nut is held through the medium of the fin 22 being engaged upon the V-shaped notch 21 of the locking member 18, the rotary motion of the nut will not change its position and consequently the screw must move with respect 4 thereto. This will cause the head 13 carried upon the end of the screw to approach or move away from the head 11, with the result that a piece of work may be engaged or released from the working faces carried by the heads.
When it is desired to use my device as a jack, it is set upon end so as to rest upon the face 31, which is broad enough to support any ordinary load to which the device may be subjected. After being adjusted beneath the load, rotation of the lever 24 will cause the screw 9 together with its rotatable member 28 to engage the load, after which engagement the member will remain stationary while the screw exerts upward pressure.
It will thus be seen that I have provided a very simple device which will accomplish all the objects above set forth.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.
Having thus described my invention, I claim In a combined vise and jack, a casting having a channel formed therein and a head adapted to co-operate with the head formed formed integral therewith, a screw adapted on said screw, means for securing said lock- 1 to move in said channel, a head formed on ing member to said casting, and a rotatable said screw, a nut rotatably mounted on said member mounted on said screw, for the pur 5 screw, means for rotating said nut, a fin pose specified.
