Early voting machines were mounted on a stand such as that shown in the Shoup et a] US. Pat. No. Zilfi -HUZ. Later machines were contained in an up right, generally rectangular cabinet such as is shown in usv Pat, No. 3,094,276 Wilson and in Design Patent 9U,405 Foehrenbach. These upright cabinets have doors which provide the voter access to the voting levers which are at a heighth suitable for use by the voter while he is standing in front of the machine. Machines such this are top heavy. They are particularly cunr bet-some while being moved. Also, the machines take up an inordinate amount olspacc while they are being stored or transporteil,
One approach to alleviating these problems has been to make the top part of the machine retractable down into the lower stand. This makes the machine much less top heavy and easier to transport and to store. in the prior art a crank mechanism has been used to raise and lower the machine from its stand. Often, this requires that the operator turn the crank handle over Hit) revolutions to raise the machine. When it is lowered it must siri'iiiarly be cranked over lUt) revolutions This is a hurderisomc job, particularly when many voting machines are to he sci up for election, or returned to storage after an election.
SUIvIMARY OF THE INVENTION In arcortiance with this invention a stand provides a convenient mechanism for raising and lowering a machine to the position in which it is to be used. When the machine is retracted diiiwnwardly into the stand it plvides a compact entity which can be easily transported and stored. The stand includes a toggle linkage actu ated by a rotor rotated by a lever. Foot pressure on The lever easily and quickly raises the machine to the position in which it can be used. Similarly, when the ma chine is to be retracted to its lowered position [or storage, operation oi'the ieve again quickiy ncconiplislrrr this operation. The toggle linkage is spring biased toward In raised position This counter balances the weigh. rithe machine and makes it possihlc to raise the hide with only a nominal foot pressure on the lever.

DESCRIPTION UP THE PREFERRED EMBODIMENT Referring to FIG. I, a voting machine VM is fixed to and rests upon a carriage member 2 which is designed to i'naintain the voting machine in either a totally closed condition (FIG. 2; or an open, usable position as seen in FIG. 3. The machine VM is equipped with a coliapsihle curtain holder 4 and curtain 6 to insure the voters privacy.
In accordance with the present invention, the mechanism of the carriage 2 both raises and lowers the ma chine or any other desired load with a minimum amount of effort on the part of the operator.
The carriage 2 comprises a frame 8 including four leg members 10 having casters (two stationery and two r0 tary) fixed thereto and two sets ofopposing toggle linkages 12 with their associated structure. A pair of fixed pivot pins l4 are secured to the leg members 10 of frame 8 as shown in FIG. 9 and located at opposite ends oicturiagc 2 in paralleled relationship. Surroundiii-g iitCil pivot 14 is a full length collar. or rotor, if to which alt the linkages and drive means are fastened.
Referring to FIGS 44, one end of a link 18 is fixed on the ends ofeach coiiar to. The other end of link 18 is tor-d to a second link 2% at 22. Link 20 is fixed at 24 to it movable platen 26 on which the machine v'M is fixed for vcrticai movement l lotational movement oi the collars It: cause a corre spun ding movement of the linkage assemblies 12 to raise or iowcr platen 26.
'Ihc ijrpposing linkages are tied together by a pair of connucnng rods .28 and .30 so that movement of one collar Mi vviii simultaneously actuate both sets of linkages. I'hc mechanism for accomplishing this rotation will he explained below.
the linkage asscmiiics II. are spring biased to their open position by means of a spring assembly .53 as shown in i'itif s. 'T and is. Welded to each ttoilar It) are a pair or" shaped arn' s 32 to which a cylindrical member 34 is fixed. A rod 36 is slidably retained in the cylinder 34 and is biased leftwardly as viewed in FIG. 7 by an internal spring 38. The spring compression can be adjusted by turning the nuts 40 against the spring stop washer 42. The other end of rod 36 is pivotally connected at 44 to a link 46 welded to the collar 16 on the opposite side. As seen in FIG. 8, each side is equipped with a spring assembly 33 operating across the center of the horizontal axis of the pins 14 to create a torsional force on each; the left pin being biased in a counter clockwise direction thereby tending to open both sets of linkages 12. The compression of spring assemblies 33 is set so as to support the weight of the machine VM to the degree that the operator need apply only a downward force of only about pounds to move the linkage from the position of FIG. 6 to that of FIG. 5.
lntegrally fixed to one collar 16 is a drive dog 48 having a series of projections 50, 52 and 54 to be engaged by pins 56 and 58 of a drive lever 60. When the machine is down and the linkages are closed, the dog 48 is in the position of FIG. 10. Lever 60 is raised and positioned on collar 16 so that pin 56 engages projection 52 of dog 48. Downward movement of lever 60 to the position of FIG. 11 will cause a rotational force to be applied to collar 16 thereby opening the linkages 12 to the position shown in FIG. 5 which is approximately one-half the total travel needed to fully open the unit. Lever 60 is then returned to its upper position (FIG. 12) until pin 56 engages projection 50 of dog 48. Subsequent downward movement of lever 60 will cause further rotation of collar 16 to completely open the linkages l2 and set them past center so they will remain in that position until the toggles are broken to close the unit.
While the unit is being used, lever 60 is slid upwardly on collar 16 via its slot 62 and is hooked to the frame 8 as shown in FIG. 1.
When downward movement of the unit is desired, the lever 60 is placed in the position of FIG. 14 so its pin 58 engages the projection 54 of dog 48. Subsequent upward movement of lever 60 will cause a C.C.W. movement of collar 16 (FIG. thereby breaking the toggles 12 and causing the unit to assume the position of FIG. 5. A manually applied downward force of about 10 pounds will cause the spring assemblies 33 to yield and will completely collapse the toggle linkages to close the unit to the position of FIGS. 2 and 6.
The lever 60 may then be hooked again to frame 8 for ease of handling.
As viewed in FIG. 2, when the voting machine is in its lowered position, it is impossible to tamper with said machine since all access doors are blocked by the frame 8. A seal 70 is applied to lock the lever 60 to the frame 8 to prevent any unwanted opening of the unit. Seal 70 includes wire which passes through hole 71 in the lever and hole 72 in the frame. These seals, long in use in voting machines, indicate by being broken that an unauthorized person has opened the machine. The use of a seal with this invention is particularly advantageous because when the seal is applied when the machine is in the down position, there is no way to enter the machine without breaking the seal.
Referring to FIGS. 16-18, the privacy curtain 6 is slidably fixed on a collapsible holder 4 which comprises two straight links 5 and a curved V-shaped member 7 which encloses the front panel of the machine as seen in FIG. 1. Member 7 is pivotally mounted at 9 to the links 5 and is maintained in its opened position by a stop pin 11 on the end of link 5. The other end of link 5 is pivoted at 13 to the inside wall of the voting machine. A stop bracket 15 (FIG. 18) is integrally mounted to each link 5 to hook over the doors 17 of the machine for properly locating the curtain support.
When the machine is to be closed, support 4 is folded up inside the cabinet as shown in FIG. 17 and the doors are closed thereby making a compact unit to be lowered into the carriage 2 as previously described.
The entire unit can then be transported with ease, possibly with two layers of machines on one truck due to their low profile. The machines can be stored in less space for the same reason and can, with a minimum of efi'ort, be opened at the appropriate time for their prescribed use.
FIG. IA shows the plate 15 which is secured to the door to prevent observance of a voter through the crack where the door is hinged to the cabinet. One leg of hinge 19 is fastened to the cabinet and alternate legs are fastened to the door. The plate 15 covers the opening presented by alternate hinged legs.
While particular embodiments of the invention have been shown and described, it will, of course, be understood that various modifications may be made without departing from the principles of the invention. The appended claims, therefore, are intended to cover any such modification within the true spirit and scope of the invention.
