This invention relates to switch stands and more particularly to switch stands of the parallel throw type.

One of the objects of the present invention is to provide an improved parallel throw switch stand device.

Another object of the present invention is to provide a simplified assembly of elements comprising a parallel throw switch stand.

Still another object of the present invention is to provide a parallel throw switch stand in which the elements thereof may be readily removed and replaced when desired.

Other objects and advantages will be apparent as the invention is more fully hereinafter disclosed. In accordance with the objects of the present invention we have devised a novel assembly of elements comprising a parallel throw switch stand including a housing, a vertically supported spindle therein, a throw lever and a thrust rod. Means are provided to translate the throw movement ofthe lever into a rotational movement of the spindle and means are provided to translate the rotational movement of the spindle into a thrusting movement in the thrust rod, thereby actuating the switch mechanism. Means also is provided to indicate the position of the switch mechanism.

Before further disclosing the nature and scope of the present invention. reference should be made to the accompanying drawing in which- Fig. 1 is a side elevation view of the parallel throw switch stand device of the'present invention;

Fig. 9 is a perspective view of the operatmg end of the throw lever of the present invention.

Referring to the drawings Fig. 1, the parallel throw switch stand of the present invention comprises a housing 1, a vertically supported spindle 14, a throw lever 5 and a thrust rod 24.

The housing 1 is preferably of one piece as shown and is provided with pads 2 adapted to be bolted to ties 3-3 by bolts 4 substantially as shown.

Spindle 14 is vertically supported within the housing 1 and is adapted to rotate about its longitudinal axis X-X by means of journal portions 15 and 16 adapted to engage in journal bearings 17 and 18 located in the top and. bottom respectively of housing 1. Preferably spindle 14 is comprised of one piece as shown which may be a casting. Alternatively, however, the spindle may be assembled from a plurality of parts into a unitary piece.

To provide means to translate the. throw movement of lever 5 into a rotational movement of spindle 14, lever 5 is provided with an extension arm 8 carrying a bearing recess 9 and spindle 14 is connected thereto by means of toggle member 11 carrying ears spindle 14 by pin 13 substantially as shown. Toggle 11 also carries bearing extension 10 adapted to engage bearing recess 9 in extension 8 of lever 5.

When lever arm 5 carrying weight 31 is rotated about the pin bearing 6 to dotted position indicated at 82 extension arm 8 rotates ings it is believed that modifications and de- I bearing openings 17 and therewith and thus displaces toggle 11 causing thereby a rotation of spindle 14 in a counter-direction.

A 180 movement of the operating lever 5 will rock the toggle member 11 and the vertical spindle 14 through an angle of substantially 90 in a counter-direction.

To provide means to convert this rotary movement into a thrust motion we provide a hub 20 integral with spindle 14 said hub having a threaded bore 19. Threaded through the bore 19 of the hub 20 we provide a rodlike lever arm 21 having an eye 22 on one end thereof which is connected by a pin 23 to the thrust rod 24 which is adapted to be connected at 25 with a movable switch point 26 (Figs. 2 and 3 Threaded bolt 21 is adjustable with respect to the position of thrust rod 24. Upon a rotation ofrspindle 14 in either direction the rotational movement is thus converted into a thrust movement in rod To provide for ready assembly of the elements comprising the switch stand of the present invention casing 1 is provided with 18 at the top and bottom respectively of the casing. Top

opening 17 has a diameter which is sufficiently great to permit spindle 14 to pass therethrough. Opening 18 is of such a diameter as to receive the journal portion 16 of the spindle 14. Shoulder 36 Fig. 6 of the spindle 14 rests on the. top of the bottom section of casing thus preventing the spindle from falling therethrough. Journal 15 is substantially of a diameter to substantially fit within the larger journal opening 17 in the top of casi 1.

cans are provided comprising a retaining collar 35 adapted to be attached to the protruding end of spindle journal 16 to prevent vertical displacement of the spindle 14. Supporting means 27 adapted to be attached to the top of the spindle 14 so as to rotate therewith is provided to carry the signal or lamp indicating means 36 as may be desired.

To provide signal indicating means spindle 14 carries said supporting means 27 upon the upper bearing 17 to attach theretoshaft means 28 adapted to carry the signal or lamp indicating means 36 in such manner that the same is rotatable therewith.

The assembly of elements comprising the switch stand of the present invention may be readily assembled, and readily taken apart, and the parts utilized therein may be replaced and interchanged. Due to the simplified structure the operation of the same is efficient and reliable.

From the above description and the drawpartures may be made in the several elements comprising the parallel throw switch device of the present invention without departing essentially from the specific embodiment herein disclosed and such modifications and departures are anticipated as may fall within the scope of the following claims:
