ELEVATING BENCH.

Application filed February 1, 1924. Serial No. 690,002.

To all whom it may concern:

Be it known that LNVILLIAM E. MUNDAY, a citizen of the United States, residing at Statesville, in the county of Iredell and State of North Carolina, have invented certain new and usefulImprovements in-l-l'levating Benches, of which the following is a specification.

The present invention relates to elevating benches, trucks, or cradles for motor vehicles and the like, andthe objects and nature of the invention will be readily understood in the light of the following explanation of the a bench or truck of improved structure capable of holding and supporting a motor vehicle inan elevated horizontal position so that ample room is provided below the car for inspection of and access to parts below the vehicle body; and to provide such truck or cradle'of a type whereby the vehicle may automatically pivot-the same to a horizontal position after having'been run up the bench when in an inclined position; andto provide means for holding the motor vehicle on the bench or truck in a stationary position.

Another very important object of the invention is to provide a device possessed of a light and durable structure which is strong and may be readily assembled and disassembled.

The invention also contemplates a structure which may be manufactured at a comparatively small cost because of the simplicity of the various parts and which will yet be reliable, and well adapted to the purpose for which it is designed. The invention comprises essentially parallel track ways pivotally mounted on supports in such a manner as to cause the track ways to assume a horizontal position by the weight of the vehicle as the latter is run thereon and means for maintaining said track ways in such position.

With the above and numerous other objects in view, my invention consists in certain novel features of construction, and in the combinations and arrangement as more fully and particularly set forth and specified hereinafter.

' In thev drawing:

Figure 1 is a side elevationof the apparatus embodying my invention,

Figure 2 is a top plan view thereof,

Figure 3 is a detail vertical section taken --s'ubstantiall v on the line 33 of Figure 1 looking in the direction of the arrows,

Figure 4 is a detail perspective view showing'one of the trackways inverted with an end leg thereon,

Figure 5 is a the main supports, and.

Figure 6 is a detail fragmentary perspective of one of the track ways showingmy improved chuck associated therewith.

Referring to the drawingsin detail it will be seen that the letter A designates the two main supports on which are. adaptedto be pivotally mounted the two trackways B. At the ends of the trackways there are provided perspective viewof one of leg apparatus indicated generally at G.

Each track way B has mounted thereon a pair of chuck members indicated generally at D. i

The main supports A are constructed with bases 1 formed of angle iron and provided with side wings 2. A standard 3 rises from the base 1 and is also constructed of channel iron, the side plates thereof being beveled at their upper ends so that the trackways may freely rock thereon.

The track ways B are formed of channel iron as is indicated at 4: and on an intermediate portion of the bottom thereof there are disposed brackets 5 which are preferably formed from sheet metal and curved so as to provide channels 6 to receive the ends 7 of the standard 3, as is illustrated to advantage in Figure 1. These brackets are disposed off center for a purpose which will become evident from a consideration of the operation of the device hereinafter set forth. A pair of sleeves 8 are provided on the bottoms adjacent each end of each track way in spaced relation to each other as is indicated to advantage in Figure 4. These sleeves receive the leg apparatus C. Each leg apparatus consists of a standard 9 having a foot 10 at one end and an angular extension 11 at its other end receivable in the outermost sleeve 8. A sleeve 12 is disposed on the standard 9 and provided with an eye lip 13. A brace bar 14 having angularly extending terminals 15 one penetrating the eye lip 13 and the other the innermost sleeve 8, holds the standard 9 at substantial right angles to the track Ways. The brace .barl l may be easily removed by-being pulledfrom engagement With their eye lips 13 and sleeve 8 so that the standard 9 may be pivoted toward the track wayso that the latter 'may be rocked to inclined position.

In using the device when the same has been set up as is shown in Figures 1 and 2 the brace bars 14 to the left of the figures would be removed and the track inclined. The automobile would then be 'run up the track ways and after having reached a certain point the track ways would automatically rock to a horizontal position that is so that the leg apparatus to the right would be restedon the floor. The other leg apparatus could then be placed in "its proper position andfthe'car is ready for inspection'or any other desired work. \Vhen the car is in this positionit is preferable thatythe chock devices D be used. Each of these devices consist of a Ushapedmeinber 20 having a T.-shaped handle and wheel engagingmember 21 thereon. The U-shaped member en- 'gages the track'way as is illustrated to advantage in Figure 6 and the 'T-shaped memberisengaged by the wheel thus preventing movementof the vehicle when on the track way. VVhenit is desired to remove the car from the track way the leg apparatus 0 to the right would be swung by removing itsbrace bar so that the track way would take the dotted line position shown in'Figure 1 because of the weight of the vehicle. The vehicle would then readily roll off of the 'incline d track way without the neces sityof using even its own power.

The'particular example of my invention which-I hav' illustratedin detail is light in Weight and construction when considered in'thelight of the work to be performed and yet is exceedingly strong and durable due to the"'strongstructural steel parts used in the trackflvay andthe main supportsA which 1. As a new article ofnianufacture', a part" to be used with an elevating device of the class described including aU-shaped member and a T-shaped member attached to one leg thereof.

2. An elevating device for automobiles in cluding apair of supports, a p'airof track- Ways rockably mounted on the supports, leg apparatus ontlie'ends ofsaid'trackways,

said apparatus including a U-shaped standard one end'of which is removably pivoted to the track way and the other end forming a foot, a sleeve on theintermediate portion of the U-shaped standard and provided with an eye lip, and a U-shaped brace bar having one end receivable in the eye 'lip, and a sleeve on trackways adjacent each leg apparatus for receiving the other end of the brace whereby said brace may be easily removed and thelegpivoted to allow tilting of the'trackway or whereby the'entire leg I apparatus may be easily removed from engagement withthe trackways. V

3. In combination, anelevat-ing device of the class describedincluding ,trackways, and chocks' associated therewith including U- shaped engaging members and T-shaped wheel engaging members.

In testimo'nywhereof I aflii my signature. v XVILLIAM" E. MUNDAY.
