Fig. 25 is'a fragmentary sectional elevation thereof, showing an attachment for use in con- In the particular embodiment of the invention shown by way of example in the drawings, my improved truck or transporting device includes a base I supported at its forward end by means of a pair of rollers or wheels 2 which preferably have their axles in alinement, and adjacent to its rear end and approximately in the longitudinal center thereof a swivel mounted roller caster 3 is provided. The base I at its front end is of U-shape and the wheels 2 are mounted at the free front ends of the arms of the U as clearly shown in Fig. 24, and the wheels 2 are also located a substantial distance forward of the hrizontal axis or center of any container X which may be transported by the truck, so that when a container is supported on the truck, a part of the weight thereof will be carried by the caster wheel 3. The base I is provided with an upstanding post or standard 4 which may be suitably secured to the base I and which may be reinforced by means of one or more suitable braces 5 which may be welded to or formed integral with the base I and the post 4. The upright post or standard 4 may extend substantially vertically, as shown in the drawings, or may slope either forwardly or rearwardly as may be desired to use the truck to best advantage.

An elevating and lowering mechanism for the containers is arranged on the post or standard 4 and preferably this mechanism is constructed to raise the container to a greater height than is necessary to transport the same, so that the container may, for example, be placed on a weighing scale or on an elevated platform or other support. This elevating and lowering mechanism is constructed to move up and down on the post 5 and may be of any suitable or desired construction, and in the particular form shown, this mechanism is constructed to cooperate with rack teeth I, which are preferably formed on the rear face of the column or. post 4. A pinion 8, Figs. 6, 8 anw 9, is mounted on the raising and lowering mechanism and engages the rack teeth 1. This raising and lowering mechanism includes a frame or body portion having a substantially rectangular hollow tubular part or guide sleeve ill which extends about the post or standard 9, so that the sleeve may slide up and down on this post. The'body portion also includes a pair of rearwardly extending arms or brackets II which are preferably formed integral with the sleeve H! and which are apertured to receive a shaft l2 on which the pinion 8 is secured. This shaft preferably extends beyond one of the arms or brackets II and a ratchet wheel [4 is rigidily secured thereto to this extending portion of the shaft, and a lever I5 is preferably pivotally mounted on this shaft.

The raising and loweringdevice is provided with a holding dog cooperating with the ratchet wheel Hi to hold the container in raised position and the lever I5 is also provided with a dog for turning the ratchet wheel. The holding dog may be supported on the raising mechanism in any suitable manner. In the construction shown for this purpose,.the body portion of thestandard includes a plate ll secured to or forming an extension of one of the arms or brackets H, and a holding dog i8 is mounted on a pivot pin E9 on the plate I] and engages the teeth of the ratchet i l. The plate H may be provided with a U-shaped extension or bracket 2i! for supporting the pivot pin H! of the holding dog and this dog may drop by gravity into its engaging position with the teeth of the ratchet H1, or if desired, a spring 2! may be employed, one end of which is fastened to a pin 22 secured to a plate crextension H of the sleeve l0, and the other end of the spring may be secured to a pin 23 secured to and extending outwardly from the dog l8. A holding dog of any otherconstruction may be employed, if desired.

The lever I5 is provided with a dog 25 pivoted thereon at 26 and urged by a spring to engage with the teeth of the ratchet wheel I l. For this purpose in the construction shown, one end of a rod 28 is pivotally secured to the dog 25, the other end of the rod passing through a hole in a guide bracket 29 extending outwardly from the lever I5. The dog is urged into a position to engage the ratchet wheel by means of a spring 30 disposed between the extension 28 of the arm and a disk 3! which is suitably secured to the rod 28. The spring 3i! is, consequently, under compression and urges the rod to slide relative to the bracket 29 in a direction. to move the dog 25 into' engagement with the teeth of the ratchet wheel M. The rod 28 preferably has the free end thereof bent over to-form a handle133, Fig.

9, by means of which the dog 25 may be manually moved out of engagement with the ratchet Wheel I4, against the action of spring 30. As a result of this construction, when the lever I5 is raised from the position shown in Figs. 1, 4 and 11, the dog 25 will cause the ratchet wheel to turn in a clockwise direction in these figures, and thus through the action of the pinion 8 engaging with the rack teeth I, will cause the sleeve Hi to be raised on the post or standard 4. Since the container to be transported is supported by the elevating mechanism of the truck, as will be hereinafter explained, this movement of the lever will cause the container to be elevated from the floor or other supporting device so that it will be supported by the truck or transporting device. If it is desired to raise the container to a greater extent, the lever 15 is again lowered, during which time the sleeve II! will be held against lowering by means of the holding dog l8 so that the dog 25 on the lever may engage another ratchet tooth of the wheel 54, and upon again raising the lever I5, the container will bemoved to a higher position. This operation'may be repeated until thecontainer is supported at the desired elevation.

Suitable means are also provided for gradually lowering the container by means of the lever l5. In the particular construction shown by way of example for this purposethe holding dog I8.- may be temporarily moved out of engagement with the ratchet wheel 14 while the dog 25 is in engagement therewith so that by swinging the lever l5 downwardly from an upper position, the sleeve l0 and the container supported on the elevating mechanism may be lowered; and these lowering means also include mechanism for returning the holding dog l8 into engagement with the ratchet wheel when the lever l5. has been swung to a lowered position. The mechanism shown by way of example for accomplishing these results includes a cam 35 on the lever !5, which is adapted to engage a pin 35 on the holding dog l8, when the lever approaches its upper position, as shown in Fig. 12, and move the holding dog l8 out of engagement with the ratchet wheel 14. In Fig. 12, the cam is shown in engagement with the pin 36 of the holding dog and this dog has been partly moved into its upper position. Upon farther. upward movement of the lever [5, the cam 35 moves the holding dog [8 into a higher position, as shown in Fig. 13, while the dog 25 of the lever is in engagement with the teeth of the ratchet wheel M.

In order to retain the holding dog IS in its upper position while the container is being lowered by means of the lever l5, a dog holding and releasing lever 38 is provided which is pivoted at 39 on a container engaging projection 40 which is secured to or formed integral with the sleeve H) of the body of the elevating member. This lever 38 has an arm 4! which is normally held by a stop 01' pin 42 in an inoperative position by the weight of the lever, as shown in Fig. 4. When the cam 35 of the lever moves the holding dog I8 into the position shown in Fig. 13, the pin 36 of the holding dog moves past the point or end of the arm 4! of the lever 38, causing the lever to-swing: about its pivot 39 until the pin 35 passes beyond the end of the part ii of the lever 38, whereupon the lever drops again into its normal position in contact with its holding pin 42, as shown in Fig. 13. lowered-'to lower the container supported by the The lever. !5 may then be truck and during this lowering of the container, the cam 35 moves out of engagement with the holding pin 35 of the holding dog it so that the pin 36 rests upon the upper face of the arm 4| of the lever 38 as shown in Fig. 14, and is thus held out of engagement with the ratchet wheel |4.

As thelever l5 approaches its lowest position,

the holding dog I8 is released to permit it to move into engagement with the ratchet wheel M to.

support the load. Any suitable means may be employed for this purpose, and'in the construction shown, the lever I5 is provided with an extension or shoulder 45 which engages the lower face of the lower arm 45 of the dog hoidinglever 38. When this shoulder 45 of the lever i5 engages the arm 46 of the dog holding lever 33, this latter lever is moved from the full line position shown in Fig. 14, into the position shown by 7 after its dog 25 has been moved manually outof engagement with the ratchet wheel l4, for example, by pulling the rod 28 against the action of the spring 30, by means of the handle portion 33 of this rod.

In order to prevent the operator from actuating the lever l5 in such a manner as to disengage the holding dog from the ratchet Wheel l4 before the dog 25 of the lever engages the ratchet teeth, the dog 25 is preferably provided with an extension 48 which would strike the U-shaped member on which the holding do I8 .is pivotedunless the dog is released by the operator. Upon releasing the rod 28, the dog 25 engages with a tooth of the ratchet wheel 14, as shown in Fig. 12, and consequently, during the engagement of the cam 35 with the pin 35, theoperator turnsthe ratchet wheel through the medium of the dog 25 to a slight extent and thus relieves the holding dog H! of the pressure of the load, so that this dog may be easily raised out of engagement with the ratchet wheel M by means of the cam 35,

Other means for raising and lowering the sleeve Ill and the mechanism mounted thereon may be provided, if desired.

of the top of the container. In the particular construction shown by way of example, this part of the container gripping mechanism includes an arm or projection 50 which is arranged to extend ove the top edge of the drum or other container,

and which has a container gripping jaw 5| which is adjustable toward and from the inner edge of the container. The arm or projection 55 is slidable vertically relatively to the lifting mechanism, and in the construction shown for this purpose, the arm is provided at its inner end with an integral collar 52 extending loosely about the upper portion of the sleeve iii so as to be movable up and down thereon, a stop pin 53 on the sleeve limiting the upward movement or" this collar on the sleeve. The arm or projection 50 is preferably also provided with a downwardly extending plate or brace 54 which engages along the front face of the sleeve. ||l so as to prevent binding of the collar 52 on the sleeve. Any other means for guiding this container gripping device for vertical movement relatively to the post or standard 4 may beemployed.

The arm 55 may be of any suitable or desired construction for. adjustaloly supporting the container engaging jaw '55 thereon. Inthe construction shown, this arm is of substantially U -shape and has a guide slot 56 formed in the bottom thereof which serves as a track on which the container gripping jaw 5| may be guided for movement toward and from the upper inner'edge of the container. The adjustable jaw 5| is provided with grooves or slots 51 in the opposite sides thereof, as clearly shown in Fig. 7, which cooperate with the arm orprojection 55 at the edges of the slot 56 therein. V

In order to move the gripping jaw 5| toward and from the inner edge of the container, I pro- The body portion of the raising and lowering device is adapted to cooperate with various types of containers. For example, in Figs. 1 to 7, the holding device is shown cooperating with a steel drum 48 having a bead 49 at'the upper edge thereof. The container engaging projection 46 is, consequently, provided with a jaw or ledge 4! formed to engage the underface of the bead 59, as clearly shown in Figs. 1 to 6 inclusive. These beads may, however, be of various forms and shapes, and it is, consequently, generally desirable to provide means fo insuring the maintaining of the bead'in engagement with the jaw i? of the load supporting projection 45. In the construction shown for this purpose, I provide an improved container gripping mechanism for en:- gaging the inner surface cf the bead 49 in such a manner as to prevent the same from slipping off of the jaw 41. This mechanism is movable vertically with reference to the hoisting mechanism vto a limited extent, and preferably also has an adjustable jaw for engaging the inner surface vide an adjusting screw 69 rotatably journalled in an upright flange 6| of the jaw 5|, the screw engaging in a threaded hole in a transverse web 62 of the U-shaped arm or projection 50. A

hand crank 63 may be provided on the end of the adjusting screw 60.

Any other means for adjusting this container gripping jaw 5| toward and from the top of the container may be provided, if desired.

' In the use of the container gripping mechanism thus far described, when a truck is moved into operative relation to the container, the hoisting mechanism is adjusted by means of the hand lever I5 so that the lower jaw 41 is in position to engage the underface of the bead 49 on the container, as'clearly shown inFig. l. The mechanism for gripping the inner surface of the container may be raised by means of a handle 65 to permit the container gripping jaw 5| to enter into the interior of the top of the container, and this jaw may be adjusted by means of the crank 53 so that it will prevent the bead 49 of the container from slipping off of the lower jaw 41. When these parts are in container-gripping positions, the hoisting mechanism may be actuated as hereinbefore described. 7

It may, at times, be necessary, in order to elevate' a container, to hold the same in spaced relation to the upright post 4 to prevent shoulders or projecting parts of the container from catching on edge portions of the base In Figs. 3,

19,20, and 21, I have shown a-spacing device this purpose, the upper end of the bar 61 maybe provided with a hole, and the lower portion of sleeve I ll.

the sleeve is'provided with an outwardly extending stud or projection 68, which may enter the hole in the upper end of the bar '6'! for suspending the bar from the sleeve Hi. In orderto guide the barfil in its movement relatively to the post or standard 4, a pair of guide arms69 may be provided which may slidingly engage the opposite sides of the post or standard. The lower end of this rod or bar 61 is provided with a barrel-engaging abutment or projection '10 which may be of a substantially arc-shape to engage the side of the container.

It is also possible that the container may beof such shape that the abutment or container-engaging part 10 of the spacer doesnot extend far enough from the bar or rod 10 to engage the container, and if this is the case, an extension member 12 may be provided whichIhas a pair of rearwardly extending hooks 13 which may'hook over the upper edge of the abutment '10, preferably between two lugs 14 thereon to prevent lateral shifting of the extension member 12. Figs. Band 20 show the extension member mounted on the container-engaging member 10. By using either the abutment 10 or the extension 12, an intermediate portion of the container may be engaged by the spacer while the upper edge of the container is secured to the lifting mechanism, so

that the container will be held in the desired spaced relation to the base, for elevating and lowering the container.

My improved truck or container transporting device may be used in connection with containers which do not have beads on the upper edges thereof by means of which the containers may be lifted. It may, for example, be desired to lift and transport barrels or other containers which must be engaged at the lower edge thereof in order to lift the same, such a container being shown in Fig. '22. In'the construction shown in Figs. 15 to 18 and 22 and 23, I have provided a device for engaging the lower edge of the container and which is raised and lowered by means of the hoisting mechanism which has been 'described.

These container-supporting means include a bar 15 which extends substantiallylengthwise of the standard or post 4, and which may also :be suspended from the stud or projection B8-of the Thisbar is of sufiicient length .to'extend to the floor on which the container .tobe transported rests and is provided at thelower end thereof with a substantially horizontally extending wedge or foot, Figs. 22 and 23, whichmay be inserted under a barrel or other container to be transported. As will be obvious from an inspection of Fig. 22, if the barrel [9 is slightly tilted, the truck may be moved toward the barrel sufiiciently to insert the foot 16 under theedge of the barrel. The bar 15 may also be provided above the foot 16 with a substantially arc-shaped barrel engaging abutment or spacer 80, which may be similar in form to the part 10 shown in Figs. 19 and 20, and if desired, an extension member 8|, corresponding to the extension member 12 shown in Figs. 19 and 20 may be applied tozthe barrel engaging part .80 by means of hooked shaped. members 82 corresponding to the members 13 of Figs. 19, 20, and 21. These arc-shaped barrel engaging members serve to holdthe barrel in correct spaced relation to the truck. For some types of containers or barrels, the extension member 81 is not necessary, but when-the sides of the staves of the barrel have considerable curvature, it may be necessary to usethe extension 8|. These arc-shaped spacers also'serve to support the container substantially centrally on the truck and prevent lateral swaying or swinging of the container during'transport of the same.

The bar 15 may be provided with guide means engaging the post or standard 4, which may be similar to those employed on the spacer shown in Fig. 19, or which may, in addition to two guide arms 83, slidably engaging opposite sides of the post 4, have a cross bar 84 secured to flanges formed. at the-rear ends Ofthe guide arms 83, so as to hold the bar 15 in correct sliding relation to the post 4.

In order to hold the barrelin substantially up right position while being li'ftedfrom the bottom thereof, adjustable means are provided "for engagingthe upper end of the barrel, and this engaging means is adjustably mounted on the bar 15.

In theconstruction shown in Figs. 15 to 1'7, 22 and 23 this barrel holding member includes a sleeve 85 slidably arranged about the bar 15. This sleeve may be provided with a set screw 86 for clamping the sleeve in the desired position on the bar I5, and 'the sleeve may'beprovided with an extension or handle 81 by means of which this barrel holding member may be readily raised or lowered on the bar 15 when the set screw 86 is released. The holding member is preferably also slidably mounted on the post or standard 4 and for this purpose may be provided with a pair of arms 88 extending to opposite sides of the post '4. Preferably this slidable connection with the post 4 is similar in construction to the connection of the bar 15 with the post 4, which "has already been described, the arms 88 corresponding to the arms 1.! of the connection already described. .These arms 88 are provided with outwardly extending .flanges 89 to one of which a cross bar 90 may be pivotatlly connected by means of a pivot pin 9|, and the other end of the bar 90 may be secured .to the other flange 89 by means of a thumb screw 92, so that the device for holding the top of the barrel may be supported by the post or standard 4, as wellas by the bar 15, and may be readily detached from the post 4 when the bottom supportingdevice is not needed.

The holding device for the upper end of the barrel also includes an arm secured to or formed integral with the sleeve 88 and adapted .to extend over the top of the barrel, this arm in-the construction shown being in the form ofeatube 94 having a barrel engaging slide mounted thereon. This slide preferably has a sleeve-like portion 95 mounted to slidelengthwise of the arm or tube 95, and is held against movement beyond the end of this tube by means of a pin 96 extending through the end portion of the tube. The sleeve part 95 has a depending barrel top engaging member secured to the lower portion thereof, that shown being in the form of an arc-shaped bar 98 adapted to fit into the inner'side of the upper edge of the barrel or other container.

In order to compensate for differences in curvature of the staves or sides of different barrels, the barrel engaging slide may be secured in different positions lengthwise of the tubular arm 94.

Any suitable means for adjustably securing this barrel engaging slide on the tubular member may be provided, and in the construction shown, a

spring pressed plunger I08 is provided which may enter into any one of aseries of .holes l0| formed in the tubular .member94. The plunger'is provided with a stem .extendingthrough a tubular spring housing I02 which may be formed integral with the sleeve 95 and a handle or knob I03 at the upper end of this stem facilitates the withdrawing of the plunger I from any one of the holes IUI, against the action of spring I04.

In the use of this device for engaging the top of. the barrel, it will be obvious that after an edge of the lower portion of the barrel has been positioned on the foot 16, the device for engaging the top of the barrel will be moved downwardly from the position shown in Fig. 22 until the arc-shaped barrel top engaging part 98 is in position to engage the inner face of the barrel l9, whereupon the knob or handle its is moved upwardly, and the slide is moved to the left in Fig. 22 into a position in which the depending container engaging part 98 engages the inner surface of the container, whereupon the knob I03 is released to permit the plunger I00 to drop into the nearest hole NH. The device will then be in a position approximately as shown in Fig. 23, whereupon the barrel may be lifted by means of the lifting mechanism through the medium of the lever l5 as heretofore explained.

With some types of containers, the holding device shown in Figs. to 1'7, 22 and 23, cannot be employed to hold the upper end of the container. For example in Fig. 25, is shown a container of this type, in the form of a drum I I0 which may be made of a body portion of a fiber board or similar material having a top HI with a relatively shallow groove or bead engaging the upper edge of the drum.- For handling containers of this type, a holding device may be provided which differs from the one described in connection with Figs. 15 to 1'7, 22 and 23, in that the arm or tubular part 94 extending over the container is replaced by a longer arm I I2. Consequently, the holding device including a sleeve H4 slidable on the arm I I2 may engage the part of the upper end of the container which is farthest removed from the post or standard 4. In order to enable the arc-shaped container engaging bar 98 to engage this part of the container, the entire holding member which is slidable on the tube H2 is reversed from the position in which it is shown in Figs. 15 to 17, 22 and 23, as is clearly shown in Fig. 25. The upper edge ofthe tubular arm H2 may be provided with holes suitably located to cooperate with the plunger I00. It .will be obvious that the operation of this mechanism is the same as heretofore described, except that a different portion of the drum or container is engaged by the arc-shaped bar 98.

The usual anti-friction rollers I [5 are mounted on the base I as shown, to engage and facilitate the up and down movements of certain types of containers with respect to the base.
