SWITCIELSTAND LOCK.

Application led .Tuly 11, 1922. Serial No. 574,338.

This invention relates to new and useful improvements in attachments for switch stands.

One object of the invent-ion is to provide a lock for a switch stand for the purpose of locking the operating handle in one or the other of the notches in the platform or table I of the stand.

Another object is to provide a device of this character which can be easily and quickly applied to a switch stand, withoutmodification or changes to the stand.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing Figure 1 is an elevation of a switch stand showing the invention applied, and the operating lever in locked position. t

Figure 2 is a side elevation of the same.

Figure 3 is a top plan View of the device, the post of the switch stand being shown in horizontal section.

Figure 4 is a perspective view of the lock, removed from the stand, and viewed from the rear, to show the opening for the apertured ear of the lever, and the latch bolt of the lock.

Referring particularly to the accompanying drawing, there is shown a switch stand which includes the supporting legs 10, the table 11, having the notches 12, with the vertical target post 18, rotatably disposed in the center of the stand, and projecting vertically thereabov-e. Secured to the post 13, by means of the bolts 14, is a radially extending casing 15, within which is pivotally mounted the oper-ating handle 16. This handle has, on its pivotal end, the apertured ear 17 which is arranged to project from the outer end of the casing 15, when the lever is swung downwardly into one or the other of the notches 12. Ordinarily a padlock is engaged through this ear 17, to hold the lever against movement by an unauthorized person, andy it is to do away with thisuse of the padlock, that the present device has been designed.

Secured at its inner end on the bolts 14, and projecting outwardly in close arallel relation to the casing 15, is a metal pliate 18, the outer end of which is bent laterally away from the casing, at right angles, as shown at 19, said laterally turned portion being Sti has its inner side open for the reception of the before-mentioned ear 17. The lock includes a bolt 23 which normally lies across the casing 22, and is adapted to be engaged and sprung back, by the ap-ertured ear 17, when the lever is swung down into one of the notches 12, thereby permitting the lock bolt 23 to spring into the opening of the ear, and hold the lever in its position in the notch 12, and against any unauthorized attempt to move the saine. The bolt 23 can only be withdrawn from the ear 17 upon placing the key 24 in the lock and turning the key. The engaging end of the bolt 23 is beveled so that the engagement thereof with the ear 17 is automatic, when the lever is swung downwardly into a notch 12.

Attention is directed to the fact that the plate 18 is attached to the stand by means of the bolts, already forming a part of the stand, and which hold the casing 15 to the post 13, thus obviating any changes or modifications to the stand, for the purpose of attaching the lock.

The upper portion of the casing 22 is arched from the adjacent end of the casing 15, to its outer closed end, whereby to permit easy movement of the ear 17 therein.

What is claimed is 1. In a switch stand lock, the combination with a stationary notched table, a rotatable target post, and an elongated casing secured to the post and having its outer end entirely open, of a lever pivotally mounted in the casing and having an apertured ear on its pivotal end extending outwardly beyond the casing, through its open end, at substantially right angles to the target post, ametal plate secured to one side of the casing and having its outer end directed at substantially right angles away therefrom, and means carried by the laterally directed end of the plate and covering the open end of the casing for engaging the apertured ear of the lever and locking the lever in position.

2. In a switch stand lock, the combination with a stationary notched table, a rotatable target post, and an elongated casing secured to the postand having its outer end entirely open, of a lever pivotally mounted in the Casing and having an apertured ear on its pivotal end extending outwardly beyoud the casing, jthrough its open end, at substantially right angles to the target 90st7 a nezxl plate secured to vone Side of the eusng and having s Outer end directed at subsantully right angles away therefrom, an elongaed lock casing extending transversely of the rst casing and covering the open ond nereo'lc and being Secured to the lf'zerally directed end of said plate, the look easing being formed with a vertical slot to in testimony whereof, We affix our Signatures.
