Application May 2, 1935, Serial No. 19,459
3 Claims. (Cl. 254-422) The object of this invention is to provide a new slots I8 provided in the channels I and 2, and and improved lifting jack, more especially for the pin I9 is mounted to slide or engage in slots lifting an automobile and holding it elevated at 20 provided in the channels II and I 2. The .pin both ends so that a workman can work under it. I9 has antifriction rollers I9a, I9a thereon that These and other objects of the invention will engage in the channels II and I2 and make roll- 5 be illustrated in the drawings, described in the ing contact therewith and reduce the sliding specification and pointed out in the claims at the contact between the pin I9 and the channels.
end thereof. Similar antifriction rollers are provided on the In the drawings: pins I1, 24 and 26. Figure 1 is a side elevation of the lifting jack Similar pins 2I and 22 are mounted rigidly in 10 shown in elevated position with an automobile the lower and upper channels, and pins 23 and 24 thereon. are mounted to slide in the slots 25 and Y26 in Figure 2 is a top plan view of the jack. the lower and upper channels, as shown at the Figure 3 is a section on the line 3:c--3a: of Figright of Figure 1. The upper channels I I and I2 ure 2, the jack being shown in lowered position are tied together by the pins I6 and 22 and by a 15 and being partly broken away at the right hand cradle, which consists of two cross bars 21 and end. 28 which are fastened to the channels II and Figure 4 is a vertical section on the line lse-4a: I 2. These cross bars are tied together by the of Figure 1, showing the parts in elevated posistraps 29 and 30.
tion. Fastened to the plate I is the cylinder 3'I. In 20 Figure 5 is a detail view of part of the mechathis cylinder slides a piston 32, which in turn nism for operating the lazy tongs. drives the piston rod 33, to which is connected a Figure 6 is a detail view of the device for lockcross bar 34. To the ends of this cross bar are ing the lazy tongs in elevated position. attached the links 35, 35 that are connected by Figure 7 is an elevation of the device as shown the pin I! to the free end 36 of the lazy tongs I3. 25 in Figure 1, looking at it from the right of Figure When the piston 32 moves to the left from the 1, and showing the jack in raised position. position shown in Figure 2, it pushes the pin I'I Figure 8 is the same as Figure 7 except that toward the pin I5 and causes the lazy tongs to it shows the jack in its lowest position. move from the position shown in Figure 3 to In the drawings like reference numerals inditheposition shown in Figure l. The lifting of 30 cate like parts. the lazy tongs is facilitated by the shape of the In the drawings reference numerals I and 2 lower members 36and 31 of the lazy tongs. These show the channel bars of the base running are bent down, so that the pins I5 and I1 are lengthwise of the jack, and 4, 5 and 6 represent further from the pins 38 and 39 than the pins 5 the cross bars on which the channels I and 2 38 and 39 are from the pins I6 and I9. In so 5 rest and to which they are connected. I indidoing, the pins I5 and II are placed further cates a plate which is attached to the channels away from a dead center on the pin 42, making I and 2. To the outer ends of the cross bars it easier to lift the lazy tongs through the first and plate are fastened the runways 8 and 9, part of its movement than would otherwise be 4 which are adapted to receive the wheels of the possible. 40 car, when the car is run to its first position on The'piston 32 is driven by compressed air, the jack. The channels I and 2 and the cross which is admitted through a tube or pipe 44 bars 4, 5, 6 and I all together constitute the base and valve 44a. The lazy tongs at the left hand of the jack' and rest on the ground. The runend of Figures 1 and 3 are lifted in this way To 5 ways 8 and 9 are supported from the dross bars raise the lazy tongs at the other end, I provide 5 by the Z-bars or brackets I0, so that the runas follows: Connected to the pin I! are the ways stand at a suitable elevation above the links 45 and 46, which in turn are connected floor on which the. cross bars rest. to the bars 41 and 48. These bars are slotted Above this base is the lifting frame, which con-' as indicated at 49 and these slots encircle the 50 sists of two channel bars II and I2. This liftpin 2I and enable the bars to ride thereon. These 50 ing frame is supported on the baseby the lazy bars are connected to the pin 24 and draw the tongs I3 and I4. In the lazy tongs I3 the pin pin from the right to the position shown in Fig- I5 is rigidly fastened in the channels I and 2, ure 5, causing the lazy tongs I4 to erect to the and the pin I6 is rigidly fastened in the channels position shown in Figure 1 at the same time v that II and I2. The pin I1 is mounted to slide in the lazy tongs I3 is erected; that is, the pins I1 55 and 24 move together to the position shown in Figure 1 when the piston 32 moves, and both sets of lazy tongs will therefore act together to lift the channels II and I2 simultaneously at both ends.
0n the stationary pin I5 is pivoted the latch 50, which has recesses at the right hand end thereof that are adapted to engage the pin l1 and hold the pin with the lazy tongs in either of three positions; namely, fully erected, in intermediate position, or in its lowest position.-
The right hand end of the latch extends out to the left as indicated at El and forms a treadle, on which the operator can step and press it down at the left hand end and release the latch from the pin I! at the right hand end. The recesses in the latch are shaped so that the pin l1 will lift the right hand end of the latch as the pin I1 moves to the left.
In operation, the device acts as follows:
The automobile is run on the runways 8 and 9, the compressed air is then turned into the cylinder 3|, and the lazy tongs are lifted to the position shown in Figure 1. As the lazy tongs lift they carry up the channel bars II and 12, which engage the automobile from underneath the body thereof, and do not engage the wheels.
The bars I and 2 engage under the front axle,
and the cradle formed by the bars 21 and 18 engage under the differential housing, and by this engagement the lazy tongs operate to lift the car off of the runways 8 and 9. So that the cradle formed by the bars 21 and 28 will correctly engage under the differential housing, it is necessary that the car be stopped on the runways 8 and 9 with the wheels in a definite place. This is secured by using the blocks 52 and 58 which are fastened on the runway. When the rear wheels rest on these blocks the car is correctly positioned for the purpose above mentioned.
For the purpose of lifting the car at the front, blocks 54 and 55 are provided which are mounted to slide on the channels II and I2. These blocks are positioned so that they will engage under the front axle. Each of these blocks has an extension 56 and 51 which engages under the kneeaction, if such is present, and in this way the car is held in level position.
I claim:
1. A lifting jack for automobiles comprising 8.
