AUTOMOBILE JACK.

Application nee April '26, 1922] Serial No. 556,803.

To all tuhom itmay concern: l Be 1t known. that I, JoHN PETER OWSIANEK, a subject of the King of Great Britain, and resident of-Ituna, in the Province of Saskatchewan, in the Dominion of Canada, have invented, certain new and useful Improvements in Automobile Jacks, of which the following is aspecification.

Tl'llS invention relates to automobile jacks,

and has for its objects to provide a lifting:

jack that is designed to be operated through suitable lever arrangementby a rack andv Further objects are to provide a meansof controlling the: line of axis of-the gears in order to force the gears in and out of mesh with the rack at will. I t

Further objects are to providein coinbination with a lifting jack, a combination pulley or handle which is to be used to opcrate the jack and which consists of. a shank I or handle bar which is provided atone end used as ahauling device.

with a recess designed to engage, the operating lever, and on -which are formed wrenches, a hammer head, a screw driver,

etc. g s I Further objects are to provide a means whereby the lifting jack may befused as I I responding parts in all the figures.

a hauling device, to provide a suitable means whereby the jack may be anchored to the ground when used as a hauling device, to

provide pulleys'inthe ack body which have a knurled engaging surface between which a cableis tobe engaged...

Still further'objects are to providea com bination lifting jack,that is simple inconstruction,..not liable to go out of repair, and generally to adapt the several parts to better perform the functions required of it.

With the above and other objects in view, the invention consists essentiallyof the improved Y construction, hereinafter described in detail in the accompanying specification and drawings. o J

Slidably mounted within the hollow body 10 is a toothed rack 12 formed at its upper end with a saddle 13 oniwhich the of the machine to be, raised is placed. F 1

Mounted in the hollow extension 11 is a plate 14 pivotally carried on an axle 15, which is retained. by means of nuts 16. The 'plate 14 is connected by two, cross-w se spindles 17am 18 to a triangular'plate 19 formed integral at one end of a lever. 20.

The lever 20 is provided with a pin 21,

cesses 22, 2.3,and 24, which are provided in which isdesigned to engage one ofthreereone ofthe walls of the lateral extension 11. I the Mounted on the spindles .17 and 13 are two gears and 26 designed to mesh with the toothed rack 12 and its axial position is controlled by the operation of the lever 20.

An arm 27 is provided, which is formed with an eye 28, encircling the spindle 17, while a similar arm 29 is formed with a like eye 29, which engages the spindle 18. The arms 27 and 29 extend outwardly of th extension 11 and have their outer ends connectedby a link 30. The link 30 is pivotally connected to the outer ends of the arms 2'? and 29 and is provided intermediate of its length with a bolt or threaded pin 31, which is designed to extend through an elongated slot 32' tormed in a lever 33, which isfulcrumed at 3 tto the walls oi. the lateral extension 11.

The arms 27 and 29 both provided with a. spring actuated dog 35, but as these two dog arrangements are exactly similar in both cases, one of them only will be described here, but it is to be understood that the two arms 2? and 29 are to be provided with a similar spring actuated dog.

The dog 35 is formed with a longitudinal slot 36 through which extends a bolt which bolt engages a sleeve or covering member 38, and has its threaded end extending through the arm 27 and securely retained therein by means of a nut 39.

The sleeve 38 may be suitably provided by means of a metal covering which has flanges 40 connected to the arm 27 by any suitable fastening medium.

The sleeve or cover 38 is formed adjacent its lower end with a slot 41 through which extends the shank of the screw nail 4-2 which is in threadedengagement with the body of the dog 35.

Obviously this screw nail 42 extending through the slot 41 ot the sleeve and the bolt 37 extending through the slot 36 of the dog provides a means whereby the dog is slidably retained within the sleeve along the arm 27. i '7 The dogs 35 may be provided at their upper ends with a bored head 43 throng which they may be connected by suitable hnks designedto reinforce the link 30 joinmg the arms 27 and 29. i I l The pin 31 on the link 30 which extends through the slot 32 in the lever 33 is loosely inaintamed in engagement in the slot 32 by ,means of a nut at, which is in threaded engagement with the threaded end of the pin or bolt 31, i i

The lower end of each of the dogs 35 is 60 provided with toothed projections 45 and 146, which are designed to engage two of the teeth of gears 25 and 26, so that the jack may raised uniformly although the lever brought back and forth] I When the rack 12 is to be raised and the lever 20 1s grasped and pulled. out in the position corresponding to the recess 24: in the wall of the lateral extension 11, which recess will be engaged by the pin 21 on the lever, thus locking the lever in position and the position thus assumed, the lever will withdraw the lower gear 26 from the teeth of the rack 12 and will force the upper gear 25 into mesh with the teeth of the rack as shown in Figure 1 of the drawings.

The lever 33 is then actuated back and forth in its downward movement, and it will force the tooth 46 of one of the dogs 35 to engage one of the teeth of the upper gear 25, which will move the same to the left, and force the rack 12 upwardly, when the lever 33 is then raised, the second dog 315 will work on the lower gear 26, and cause the same to rotate to the left. The gear 26 will transmit its motion in a reverse direction to the gear 25 which will thus actuate the rack 12 in the same motion, thus affording on the. two movements of the lever 33 a uniform raising motion. When the rack has reached the heightdesired, the lever 20 is brought to neutral position, that is the pin 21 is brought into engagement with the recess 23 provided in the wall of the lateral. extension 11, when the two gears 25 and 26 will be in mesh with the rack 12 as shown in Figure 2 of the drawings, thus locking the'rack in position.

When the rack is to be lowered, the lever 20 is again moved towards the body 10 of the lifting jack and the pin 21 brought into engagement with the recess 22, thus'withdrawing the gear 25 from engagement with the rack'and forcing the gear 26 to mesh with the teeth of the rack 12. The lever33 is then actuated back and forth as previou sly, and the action is reversed as the gear 26 is then the one which transmits the motion to the rack 12. i

It will be obvious that the rack will be loweredby' the movement of ,the gear 26, which is propelled by the dogs 35. In order to afford a better means of operating-the lever 33. the same is formed with ,an arrow extension 47, which is designed to engage a recess 41-8 formed in the end of ahandle bar 4-9, which is provided with an extension 50. The extension 50 carries a collar 60, which engagesthe bar 49 and the outerend of the .bar 4;9 carries a similar collar 61,

which is provided with a set screw 62 designed to be tightened on the extension '50, and securely lock the same in its extended or collapsed position. 'w

The member 49 may be formed as a combination tool being provided onone side with a hammer head 63, while opposite to this wrenches 64 and 65 are provided. If desired also the outer end of the extension 60 may be formed with a screw driver 66, which may also be provided with an orifice 67, of such shape as to be designed .to enand 69. 1

' vided, which maybe suitably strapped to] on the handle b'ar49 may be suitably secured thereto by means of rivets as shown at 68 The rack l2is to be slidablyi'retained within the hollow body 10 by means of a pin 70 extending crosswise at'the lower end of the rack 12 and designed to become engaged by recesses 71 formed in the lateral walls of the body 10 of the lifting jack.

This lifting jack may be operated by the movement ofthe'lever'33, which is provided with the combination member 49 according to the method already described, and the rack 12 will be limited in" its upward movement by the pin 7 being-brought into engagement with the recess 71 formedfin the inner walls of the body The jack A may also be adapted tofbe used as a hauling device, according to the following. i

73, and has its other end notched seat 7 1 in order to allow the free "passage of a cable 7 5, which is to be engaged betweentwo pulleys 76 and 77gmounted onythe spindles 17 and 18 respectively adjacent the gears and 26.

The gripping/surface of the pulleys 76 and 7 7 is knurled in order-to firmly engage the cable 7 5, the outer end of which extends underneath the pulley 76 between the two lateral walls of the extension 11 at the up-, per end thereof.

When the jack is to beused for hauling purposes, the rack 12 is extended completely outwardly, until the pin comes into engagement with the recess 71 and the ack being placed flat on the ground, the wedge 78 is driven into the same. For this purpose a the rack may be formed at its upper end with a slot 7 8 in which rollers 79 are mounted, which frictionally engage a spike 80 which may be driven into the ground by means of. the hammer provided on the member 49. Also in order to provide a further means of securing the jack to the ground, a

plate formed with inclined spikes 81 is prothe rack 12.

When the device is to be used for this purpose, as for instance when the car is caught in a mudhole, and cannot make any more progress, the device is set in front of the car as previously describedjand shown i n- Figure 14; of the drawings, and the cable bethegear' will thus readily be pulled out and the deviceis dismounted, and-when placed "in collapsed position does not occupy a'larger space than an ordinary lifting jack;

affords an efiicient lifting ack, and a hauling device that may be suitably operated when the same is neededin a place where it would be diflicult to get help otherwise.
