A manually operable screw member 100 is also provided, and the numeral 99 indicates pivot mounting pins or means for the platform 6, and the platform 6 can be pivoted about an axis extending through the pivot mountings 99 by manually actuating the screw member or rod 100.

As shown in the drawings the base 21 is provided with casters or rollers 101 and 102 which facilitate the convenient movement of the crane or jack to the desired location.

The numeral 103 indicates an actuator which includes a cylinder 104 that has a piston rod 106 extending therefrom, and the cylinder 104 is pivotally connected to the channel member 88 as at 105. The piston rod 106 is connected as at 108 to a cross piece 107, and the cross piece 107 is secured as by welding to a pin 90, FIGURE 11. The numeral 110 indicates a fitting which may be suitably connected to the cylinder 104 whereby compressed air or the like can be introduced into the cylinder 104 to actuate the device 103, and a release valve 111 may be provided for the cylinder 104. Instead of using compressed air for actuating the device 103, hydraulic fluid or the like can be used.

From the foregoing, it is apparent there has been provided a crane or jack which is especially suitable for use in automobile repair shops, service stations or the like, and with the parts arranged as shown in the drawings, the present invention can be used for jacking up an end of a vehicle such as an automobile, and in addition it can be used for various other purposes such as for raising or lowering a heavy member such as an engine block, the vehicle transmission or the like.

With the parts arranged as shown, the device 20 can be readily moved from place to place as desired due to the provision of the casters 101 and 102, and one of the uses of the present invention is for jacking up an end of a vehicle such as an automobile, and to jack up such a vehicle the brackets 29 are adapted to be positioned beneath a bumper such as the front bumper of a vehicle being worked on or repaired. The brackets 29 are swivelly or pivotally connected as at 30 to the members 28 so that the brackets 29 can be moved to the desired or proper position relative to the vehicle bumper or other part of the vehicle being engaged, and in addition the members 28 are adjustably mounted on the bars 27 so that the brackets 29 can be moved in or out towards or away from each other in order to permit these members to be positioned at the desired location. Then, to jack up an end of the vehicle, it is only necessary to actuate the device 51 as for example when the parts are arranged in a position such as that shown in FIGURE 6. Thus, as shown in FIGURE 6 the piston rod 56 is disconnected from the clamp 57, and instead the piston rod 56 is connected as at 79 to the flanges 76 and slotted portions 78 of the arm 77, so that when the piston 56 is caused to be moved by the introduction of hydraulic fluid, air under pressure or the like into the cylinder 53, the piston 54 can be moved upwardly in the cylinder 53 and this will cause the piston rod 56 to move upwardly. As the piston rod 56 moves upwardly, it will cause the pair of arms 77 to be raised, and since these arms 77 are connected as at and 81 to the movable carriage 31, it will be seen that this upward movement of the arms 77 will cause the carriage 31 to be raised. In view of the fact that the bars 27 are secured as by welding to the carriage 31, it will be seen that this upward movement of the carriage 31 will raise the bars 27 whereby the brackets 29 which are below the vehicle bumper or the like will cause an end of the vehicle to be jacked up in order to permit various types of work to be more conveniently performed on the vehicle.

The device 51 may be actuated by any suitable means such as hydraulic fluid, or else the compressed air from a suitable source of supply in the repair shop can be introduced into the fitting 55, and a vent opening 61 can be provided for permitting the discharge of air or the like from the cylinder 53 as the piston 54 moves upwardly.

In addition, the parts can be arranged as shown in FIG- URE 1 for example so that the piston rod 56 has its upper end connected as at 60 to the clamp 57 instead of being connected as at 79 in FIGURE 6. With the parts arranged as shown in FIGURE 1, the device 51 can be actuated so as to cause the rod 56 to move upwardly and this upward movement of the rod 56 will cause the boom 62 to pivot about an axis extending through the pin 65. With the parts arranged as shown in FIGURE 1 the hook 68 of the chain 67 may be connected to an engine or other heavy piece of equipment so that as the boom 52 is pivoted on its pivot pin 65, the object or load being handled can be readily and conveniently lifted for any desired purpose. Similarly, the device 51 can be operated in such a manner as to permit the boom 52 to be lowered, as for example when a replacement engine or the like is being positioned or mounted in an automobile or other vehicle. The hook 68 may be connected to a suitable chain, line or the like which can be suitably connected to an engine or other article being handled.

The boom 52 has an extensible construction so that the effective length thereof can be regulated as desired and this can be brought about due to the provision of the mechanism 74. Thus, by manually gripping the member 70 and pivoting it on its axis or pin 71, the dog 72 can be moved out of engagement with the teeth 73 in order to permit the section 64 to be positioned at the desired location, and then the dog 72 and member 70 can be returned to a position such as that shown in FIGURE 8 whereby accidental shifting of the section 64 from its adjusted position will be prevented. A suitable spring mechanism may be provided for the locking device 74 in order to help hold the section 64 immobile in its adjusted position.

As the carriage 31 moves up and down, its rollers 37 and 41 will engage the portions 36 and 40 respectively whereby the carriage 31 will be properly guided during its up and down travel or movement.

In addition, the crane or jack of the present invention can be used as follows. The angle irons or bars 94 can be suitably secured to a member such as the vehicle transmission as for example by means of bolts or securing elements which extend through the openings 95 in the angle irons 94 and then, by actuating the unit 103 as for example by means of compressed air, hydraulic fluid or the like, the rod 106 can be moved outwardly of its cylinder 104, FIGURE 11, and since the rod 106 is secured as at 103 to the member 107 which is welded or otherwise affixed to the pin 90, it will be seen that with the pin 90 secured as by welding to the member 89, this actuation of the device 1103 can be used to pivot the links 89 and 91 as for example from a position shown in solid lines in FIGURE 11 to the position shown in broken lines in FIGURE 11. This clockwise pivotal movement of the links 89 and 91 from the solid line posi tion of FIGURE 11 to the broken line position of FIG- URE 11 will cause the angle irons :94 to be raised Whereby a vehicle transmission such as the transmission 47 can be suitably lifted.

The motor which has been lifted may be bolted to the adapter 45, as for example by means of bolts or securing elements which connect the motor to the openings 46 in the adapter 45, and the tubular member 44 of the adapter 45 can be positioned in the bushing 43 and held in place by means of the set screw 49.

The parts can be made of any suitable material and in different shapes or sizes.

While the present invention has been described specifically for use in connection with repair of vehicles or the like, it is to be understood that its use is not limited to such work on vehicles and in fact may be used wherever various types of loads are being handled or lifted or the like.

With the present invention an automatic transmission of a vehicle can be conveniently and easily removed or replaced. In effect the present invention can be used as a combination hydraulic crane and engine rebuilding stand and hydraulic jack, and the present invention is especially suitable for use by a garage owner or operator since they will facilitate the lifting of heavy loads such as installing or removing engines in various types of vehicles such as vehicles used in every day operation as Well as racing cars or the like. With the present invention the engine can be removed from the vehicle and an adapter can be attached to the bell housing and this adapter can be used on most engines and the engine can be rotated in any desired position for rebuilding. The device 5'1 can be easily used for pivoting the boom 62 as for example when the parts are in the position of FIGURE 1, or else the device 51 can be arranged as shown in FIGURE 6 so that it can be used for moving the jack members 29 as previously stated. The bumper brackets 29 are arranged so that they will rise on an even keel. When hydraulic fluid is used as the actuating medium, suitable control valves or the like can be provided for controlling operation of the device. The present invention is especially suitable for small garages such as one man garages since with the present invention one person can conveniently raise or lower various types of heavy members, engines or the like.

The present invention can be used as a vehicle engine removing device so as to facilitate the removal and rebuilding of engines, and it can also be used as a hydraulic bumper jack and a means for removing an automatic transmission all in one unit so that for example a one man garage operator can remove and rebuild a motor, lift the car and remove the transmission where space is limited. In addition, a motor can be pulled out in such a manner that it will clear the radiator and fenders.

In actual practice the boom can be lowered with the motor attached level with the motor building stand, and then the adapter 45 can be attached to the bell housing and the motor can be completely turned around and inserted into the motor building stand and the boom and chain can then be disengaged. The boom is then adapted to be raised and positioned in a suitable location so that for example the motor can be turned and rebuilt with greater ease. In addition the present invention can be used to support a boring bar as for example when cylinders are being rebored.

After work on the motor has been completed, the boom can be lowered to a horizontal position and attached to a harness such as a chain and swivel pulley on the motor so that the motor can be raised sufiiciently high to clear the fenders and the radiator. The boom can be telescoped by the ratchet mechanism 74 whereby it can be positioned at the desired location. Then, the device 5 1 can be disconnected from the clamp 57' by removing the pin 60, and the device 51 can be connected as at 79 as shown in FIGURE 6 so that by actuating the device 5-1 the jack brackets 29 can be raised so that the vehicle can be elevated to the desired amount.

Due to the provision of the pivot pin 37, the parts such as the angle irons 94 can be shifted to the desired location, and the device 103 can be suitably actuated in order to raise or lower the members 94 as previously stated. The transmission can be disengaged from the vehicle and can be lowered or raised as desired so that it can be worked on or rebuilt or the like.

It Will thus be seen that there has been provided a portable crane which can be operated by a hydraulic mechanism or the like, and the crane of the present invention is especially suitable for use in installing and removing an engine, and it can be used for lifting an engine out of a vehicle such as an automobile and raising the engine suificiently high to clear the hood and fenders. Then, an adapter can be attached to the bell housing and the engine can be positioned at the desired location as for example at bench level and the motor can be rebuilt by rotating the motor 360 and the boom can then be moved out of position. In addition the present invention includes the bumper jack attachment 29 which can be used for raising the front or rear of the 'vehicle, and then the 7 parts can be raised or lowered quickly or slowly as desired or required, and in a safe manner.

The boom 62 is of the telescoping type and can be positioned to pull out the motor, and after the motor is pulled out of the automobile or other vehicle, the boom can be adjusted so that the motor can be moved close to the stand, and then the boom can be disconnected from the device 51 so that the jack brackets 29 can be actuated to raise or lower the vehicle.

It is to be noted that the present invention includes the two I-beams that form the base on the floor with four casters, two being arranged in front so that they are fixedly mounted, and the two rear casters being swivelly arranged and this construction permits the device to be readily moved around a work shop or other locality where the same is being used. The member includes the upright portion which has the telescoping boom attached thereto for facilitating the removal of a motor or any other heavy object as for example by pushing the unit under the object to be removed and telescoping the boom by means of a ratchet mechanism that includes the plurality of teeth, and after the parts have been moved to the desired location, the chain and cable mechanism which includes the swivel mounting 115 for the chain 67 and hook 68, is adapted to be used for facilitating the removal of a motor out of the spline and motor mount.

After the motor has been raised, the actuator 51 can be actuated so that the piston rod 56 can move the boom 62 with the motor attached thereto, sufiiciently high to clear the radiator and the fenders, and then the complete lift is pushed away from the automobile and then lowered approximately to a horizontal position and then the ratchet is actuated to bring the motor closer to the motor building stand as indicated by the numeral 43.

The bell housing adaptor 45 is attached to the motor and the motor can be completely turned around on the swivel attachment at the end of the chain and inserted into the member 43 and then the boom 62 is raised by removing the pin 60 and the boom can be positioned overhead or at an inclination at an angle of approximately fifteen degrees.

The boom 62 will thus be out of the way so that the operator can repair the motor with suflicient head clearance to permit the operator to completely walk around the motor building unit. The boom 62 can be safety locked in such a fifteen degree overhead or inclined position as for example by inserting a locking pin through openings 116 and 117 that are adapted to register or be aligned when the boom is moved to the desired inclined elevated position. The actuator 51 can then be positioned in a vertical position and then the clevis pin 60 is extended through the slot 7 3 and through the member 76, and then by actuating the unit 51, the piston will push the member 77 whereby bar 27 will be engaged and will provide a bumper jack to raise the automobile sufficiently high to permit the operator to do the necessary work under the automobile or other vehicle. The unit is adapted to be pushed under the vehicle with the attachments 82 and 88 attached which are movable when they are not being used. In the event that the operator wishes to remove a transmission, the units 82 and 88 are attached and the mechanism is pushed in front of the vehicle and the bumper of the vehicle is engaged by centering the members 30 in the proper position and actuating the cylinder unit 51. The front of the car is adapted to be raised sufficiently high to permit the operator to move the transmission by positioning the members 82 and 88 in the proper location and actuating the cylinder 104 of the unit 103. After the transmission has been disengaged from the vehicle, two chains are adapted to be secured forward and rearwardly of the transmission and these chains are adapted to be securely fastened for safety precautions. The transmission is tilted forward by a screw thread, and then the members 88 and 82 are pushed forward or backwards on rollers 84, and then by actuating suitable release valves for the cylinder 104, the transmission can be lowered and the casters will take up the weight and this permits the transmission to be pushed ninety degrees on either side of the automobile or vehicle at the option of the operator.

It is to be noted that there is sufficient clearance under the boom on the members 88 and 82 after the transmission is pushed out from under the vehicle to again permit the operator to raise the transmission approximately twenty-four inches to insert a seal or any small minor repair needed for the transmission, or else it can be raised sutfieiently high to permit one man to pick up the transmission or push it onto a bench where he can readily dismantle it and repair it, and the same procedure is adapted to be used when installing the transmission back into the vehicle.

The present invention is especially suitable around a one-man garage since with the present invention one person can remove the motor and rebuild the same on the motor building stand at bench level so that he can turn the motor completely 360 and lock it in a position necessary to remove the pistons, crank shaft and the like.

In addition the present invention can pick up a heavy object and can be readily and conveniently wheeled into various locations such as dunking the motor into a solution for degreasing. The motor never touches the floor and the boom, being in the fifteen degree position which is sufficient clearance for the operator to completely walk around it, is an important feature. The unit takes a very little amount of storage space and it can be pushed under the car up to the point indicated by the numeral 48 so that very little space is consumed in storage or the like. The attachments 82 and 88 are disengaged and stored in a convenient space until necessary to use them.

The angle irons 94 and associated parts are adapted to form the base for automatic transmissions and the like, and the pieces 11 have a series of holes 10 therein whereby the pin 98 can go therethrough. The base is adapted to be raised approximately one and one-half inches over the member therebelow so that it can be tilted at approximately ten degrees on either side and this is adapted to be accomplished by operating the gear 18 underneath the base, FIGURE 13, the gear being operated by means of the handle 17 which is extended to the right of the automatic removal unit.

The units 51 and 103 can be operated by air pressure, hydraulic fluid or the like as desired or required.

It is to be noted that the same cylinder or actuator 51 operates the motor boom and jack simply by removing the pin 60 and inserting it into the slot needed as previously described.

Two swivel casters 7 are adapted to be engaged on the member 88, and they may be extended eight inches on each side, and these casters do not support the member 88 until after the transmission has been engaged and lowered onto the automatic transmission remover unit.

With further reference to FIGURE 11 of the drawings, it will be seen that this part of the device includes the channel iron boom that will raise and lower a transmission such as twenty-four inches, tilted forward ninety degrees and turned either side ten degrees to facilitate removal of the transmission, and there are two safety chains 8 that are securely afiixed around the transmission 47 for safety precautions.

A series of openings are provided whereby four channels can be positioned under the automatic transmission bar and centered to form an attachment whereby the pin and transmission can be secured for removal.

As shown in the drawings, the two swivel casters 7 are attached to the channel 38 and the purpose of these swivel casters is to help support the transmission after it has been lowered onto the automatic transmission removal unit.

The cradle functions to facilitate removal of the transmission which is tilted forward ninety degrees by a screw attachment, and the ten degrees on both sides tilt is achieved by the gear segments attached to the worm gear located on the side of the cradle, FIGURE 13.
