COMBINATION JACK AND HOIST.

Application led February 8, 1922.

able others skilled in the art to which it ap* pertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part-of this specification.

This invention relates, generally, to improvements in combined lifting jacks and hoists; and, the present invention has reference, more particularly, to a novel combina! tion jack and hoist for use especially with automobiles which is simple in its construction and is effective, both for lifting the axle and wheel of a vehicle for a. change of tires. or for drawing or pulling` the vehicle out of the sand or mire when the wheels have become imbedded in a manner, that the wheels when operated will not grip, and will cause a possible loss, due to battery-exhaustion, strain upon the engine, or wear and tear upon the tires.

The present invention has for its principal objects to provide a novel and simply constructed combination jack and hoist of the general character hereinafter more particularly set forth and for the purposes herein-before stated, which is most simple in its construction, is positive in its action, and is adapted for use either as a jack for lifting purposes, or as a hoistfor pulling the vehicle out of a ditch or over an embankment, or out of the sand or mud, when deeply mired therein.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the same.

Tith the various objects of the invention in view.`the said invention consists, primarily. in the novel combination jack and hoist hereinafter more fully set forth: and, the said invention consists` furthermore, in the novel arrangements and combinations of the various devices and parts. as well as -in the details of the construction of the said parts, all of which will be more fully described in the following specification, and

serial no. 534,919.

then finally embodied in the clauses of the claims, which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a detail view of the combination jack and hoist. shown in a horizontal position with a flexible element extending from each end horizontally to illustrate the use of the device when in tension in connec tion with a vehicle for pulling the same out of a ditched or mired position.

Figure 6 is a horizontal section, taken on line 6-6 in said Figure 3; and Figure 7 is a detail vertical representation of the parts represented in said Figure 6. said section being taken on line 7-7 in said figure.

Figure 8 is a Jface view of certain portions of the device, looking in the direction of the arrow u in said Figure 7, with a. portion of the gear-casing shown broken away; and Figure 9 is a fragmentary view, showing the jack-feature partly in perspective and partly in section.

Figure 10 is a detail horizontal sectional .representation taken on line 10-10 in said Figure 8.

Similar characters of reference are employed in all of the said above described views. to indicate corresponding parts.

Referring now to the several figures of the drawings. the reference-character 1 indicates a complete combination jack and hoist. showing one embodiment of the principles of the present invention, the same comprising a main shell or casing consisting of a base-plate 2 formed with suitably disposedA openings` as 3. Suitably mounted upon said base-plate 2 are two vertically disposed side- pflates 4 and 5. which are preferably slightly contracted toward each other,

as at 6 and 7, see Figures 6 of the drawings, to provide a narrow space-portion 8 in which is vertically disposed and movably arranged a rack-member 9 formed upon one edge with pawl-engaging teeth 1() and upon its upper' end with a supporting or engaging end\11, adapted to be moved against an axle 12 of the vehicle for lifting purposes, as indicated in Figure 4 of the drawings. A spacing-plate 13 and a gate-plate 14 are arranged between said side- plates 4 and 5, the said plate 13 and the side-plates 4 and. 5 being secured together by means of tie-bolts or screws 15, and the said gate-plate 14 and side- plates 4 and 5 being secured together by means of a tie-bolt or screw 16 which also acts as a. means of pivotal connection for the said gate-plate 14, and a tie-bolt or screw 17 with which a hookshaped portion 141 of t-he said gate-plate 14 can .be brought into separable holding engagement, asf` will be evident from an inspection of saidFigure 4 of the drawings. At the proper locations between thel said side- plates 4 and 5 are suitably formed guide-members or elements, as 18 'extending inwardly from an opening 20, and a guide-member 19 secured in place by a tiebolt or screw 21, as shown, for properly maintaining the rack-member 9 in its vertically movable relation between the said Side- plates 4 and 5, as will be evident.

Extending through a suitably y,disposed perforation in the guide-member or element 19 and through correspondingly placed perforations in the sideplates 4 and 5 is a pin or stem 22 the ends of which project beyond the outer faces of said sidelates forv the pivotal arrangement thereon o the eyes 24 of a bail 23 to which may be attached aV chain 25, or the like, for the purposes hereinafter more fully set forth. Pivotally mounted upon a pin or stem 26 extending across the space between the said side- plates 4 and 5 is a lever-receiving Socket-member 27 preferably of the construction shown in Figures 3 and 4 of the drawings, for the re ception of the end-portion of an operating lever or handle 28, which may be detach-- ably secured in said socket-member and maintained in its operative relation with .said member by a removable cross-pin 29.

Pivotally mounted upon said pin or stem 26 is an upwardly extending dog or pawl 30, the said socket-member 27 being provided with another pin or stem 31 upon which is pivotally mounted a second upwardly eX- tending pawl or dog 32, a suitably formed spring, as 33, connecting the said pawls or dogs 3() and 32, for forcing their rackengaging end-portions into slidable engage` ment vwith the teeth 10 of the rack-member 9, as will be evident. The manner of raising the rack-member 9, by means df said pawls or dogs and the handle or lever 28 will be clearly understood from an inspection of Figure 4 of t-he drawings, and is as follows:

Let us suppose that the various parts of the device are in the positions indicated in Figure 4 of the drawings, and that the rack 9, with its load 12 is to'be raised, the two pawls 30 and 32 being in the position shown. The operator throws the plvoted latch or lever 34 in a direction toward the rack-member 9, causing the lug 35 of said latch or lever 34 to be rotated in a downward direction until its free end-portion is forcibly brought into contact with that portion of the spring 33 where its end-portion is attac-hed tothe side of the pawl 30. By lifting the lever 28, the engaging portion of the pawl 30 remains in engagement with the rac-k 9, the pawl 32 being moved in a downward direction a suicientdistance to permit the spring 33 to act toward and upon said pawl 32, thus forcibly bringing its engaging end in holding engagement with the oppositely disposed tooth of the rack 9, as will be evident. The lever 28 now being swung in a downward direction` the engaging end-portion of the pawl 32 i causes the rack 9 to be moved in an upward direction, the pawl 30 being forced out. of lts engagement with the tooth of the rack,

Ybut being immediately forced into active engagement with the next succeeding tooth by step, the operator returns the latch or lever 34 to its former position, indicated in said Figure 4 of the drawings, thereby withdrawing the lug 35 from its engagement with the spring 33. A downward movement of the lever 28. owing to the action of the spring, forces the. pawl 32 into lifting eny gagement with the rack. and raises the Same slightly, so that the spring 33 now forces the other pawl 30 out of its engagement with the rack, and so that as the lever 28 is raised, the rack, still in engagement with the pawl 32 moves in a downward direction. while the spring 33 Aacts to force the pawl into act-ive engagement with the succeeding and downwardly moving tooth of the rack, as will be clearly evident.

If desired the rack-member 9 may also be' provided in its opposite sides with grooves or channels 37, the opposite portions- 6 and 7 of the side- plates 4 and 5 in that case being formed upon their inner faces with correspondingly placed guide-lugs or protuberances, as 38, and as indicated more particularly in Figure 10 of the drawings.

Referring now to Figures 2,3 and 5, there is attached by means of some of the tiebolts or. screws 15, the tie-bolt or screw' 16, and the cross-pin 36, in a proper location upon the outer face of the side-plate 4, a shell or casing 39 across the chamber formed by it and the said side-plate 4, also extends the previously mentioned pin or stem 26. Disposed withinthe chamber thus formed and mounted upon a shaft 4() isa ratchet-wheel 41, the said shaft 40 being rotatably journalled in a bearing-portion 42 in said shell or casing 39, see Figures 2 and 3, and in correspondingly disposed bearing- portions 43 and 44, indicated in dotted outline in Figure 7 of the drawings. Suitably secured upon the outer face of the sideplate 5, by means of screws 45, see Figure 8, or in any other suitable manner, is a gearcasing 46, in which is disposed a. pinion 47, the hub-portion 48 of which is suitably affixed to the Yend-portion of the shaft 40 which also extends into the chamber formed by said gear-casing 46 and the outer face of the side-plate 5. The said side- plates 4 and 5 are also provided with other bearingportions, as 49 and 50, in which is journalled a shaft 51, having suitably affixed thereon by means of a set-screw 52, or in any other suitable manner, in the space between said side- plates 4 and 5, a suitably formed chaincarrier or shea-ve 53 with which. can be brought in active engagement the links of al chain 54, the ends of said chain, ordinarily, being movably disposed in the openings 3 of the base-plate 2, substantially as indicated in Figure 4 of the drawings. Rotary motion of said shaft 51 and said chain-carrier or sheave 53 is obtained from a gearwheel 55 which is suitably fixed upon that end-portion of the sha-ft 51 which extends into the chamber formed by said gear-casing 46 and the said side-plate 5, said gear-wheel 55 being actuated from the pinion 4T which is in mesh therewith, in the manner and for thev purposes to be presently set forth. Pivotally mounted upon that portion of the pre-` viously mentioned pin or stem 26 which extends across the above-mentioned chamber formed by the shell or casing 39 and the sideplate 4 is a lever-receiving socket-member 56, similar in its construction to that of the, socket-member 27, said socket-member 56 being adapted to receive the end-portion of the previously mentioned operating lever or handle 28. as indicated in Figure 5 of the.

drawings. said lever being detachably secured in said socket member 56 by means of a removable cross-pin 5T, Also pivotally mounted upon said pin or stem 26 is a downwardly extending pawl or dog` 58,` the said socketmember 56 being provided with another pin or stem 59 upon which is pivotally mounted a second downwardly extending pawl or dog 60, a suitably formed spring, as 61, connecting the said pawls or dogs 58( and 60, for forcing their engaging end-portions into slidable and active engagement with the teeth of the ratchet-wheel 41, in substantially the same manner, as previously described in connection with the pawls 30 and 32, and the rac-k 9. The manner of actuating the chain-carrier or` sheave and the chain from the said ratchet-wheel, when operated by the handle or lever 28 and the dogs or pawls 58 and 60 will be clearly understood from an inspection of Figures 5, 6, 7, and 8 of the drawings, and any further description of the same is therefore deemed unnecessary, and from an inspection of Figure 1, one manner of using these last-described elements of the device as a hoisting or pulling means will be clearly understood.

Vvvhen the device is to be used as a jack. in order that the device may be properly placed upon its base-plate 2, the gate-plate 14 may be moved into its opened position, in which case the strands of chain are withdrawn through the openings 3 in the baseplate 2, and drawn out through the opened portion of the main casing, but without having to remove the chain from the chain-carrier or sheave.

From the foregoing description of the present invention, it will'be seen that I have produced a simply constructed and effectively operating device, which is readily convertible into a jack for lifting purposes, or into a hoist adapted for various uses to which a hoist is applicable.

Of course. I am aware that changes may be made in the general arrangements and combinations of the various devices ,and parts, Aas well as in the details of the construction of the said parts, without depart.
