CARRIAGE OR WAGON JACK.

SPECIFICATION forming part of Letters Patent No. 360,116, dated March 29, 1867.

Application filed January il, 1887. Serial No. 223,169. (No model.)

To all whom t may concern:

Be it known that l, HENRY Sacco, a citizen of the Republic of France, and a resident of New York city, in the county of New York 5 and State of New York, have invented certain new and useful Improvements in Carriage or `\Vagon Jacks, of which the following is a specieation.

Previous to my invention numerous contriv io ances have been devised for lifting the axles of coiiveyances for the purpose of removing the wheels or washing the same; but to all such contrivances, so far as my knowledge extends, there has existed some objection, either as to i5 Construction or mode of operation.

Myinvention has for its main objects to pro` duce a carriage or wagon jack which shall be simple of construction, easy and speedy of operation, and capable ot' performing all the 2O functions required by those having occasion to use suoli contrivances.

To these ends and objects niy invention consists in the various features of construction and combinations of parts, hereinafter more fully explained, and particularly pointed out in the claims 'of this specification.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a contrivanee embodying myinvention. Fig. 2 isa de- 30 tail view ofthe lifting bar or frame detached.

Fig. 3 is ahorizontal section taken at the line .r of Fig. 1. Fig. 4 is an enlarged perspective View ofthe upper portion ofthejack. Fig. 5 is a horizontal section taken at the line y y of Fig. 1, and Fig. G is a perspective view of the adjustable block or support detached.

In the several views the saine parts will be found designated by the saine letters and numerals of reference.

A is a post or standard,preferably of wood, and enlarged at its lower end to form feet a a, to which are bolted at I) b,on each side thereof and at rightangles thereto,two additional feet, c c, thus providing a substantial base for the structure. The post or standard is slotted shown, is fulcrumed in said post by a pin or bolt, 5, passing therethrough and through a hole in the lever and secured by nuts orheads 6, washers 7 being introduced between the 55 nuts or heads and the sides of the post, as illustrated.

C is the lifting bar or frame, constructed to slide vertically in front of the post A. At two points, preferably, the lifting-bar is pro- 6o vided with perforated lugs or ears 8 8, which are fitted to slide in the slotted front of the post,and are held in place by bolts or pins 9 passing through the slots 1 and 2 and the eyes in the lugs or ears 8 8. Nuts 10 retain the 65 bolts 9 in place.

The lifting bar or frame, made preferably of metal, is composed, essentially, ot' a back bar,

1l, and an inclined front bar, 12, in addition to the perforated lugs above mentioned. The 7o back bar is provided with two racks, 13 and 14, and the front bar with a row of upwaidlyinclined teeth l5. At the upper end of the lifting-bar is provided a seat, 16, for supportlng the axles of high vehicles. At 17 the lift- 75 ing-bar is perforated, so that cheek-pieces 1S, preferably of wood, may be secured on each side thereof by bolts or rivets 1).

D -is a detachable adjustable axle-support, preferably of metal, consisting, essentially, ol' 8O an axle seat or bearing, 20, and a bar or plate,

2l, provided with downwardly-ineliiied teeth or lugs 22, to lit into the spaces between the teeth 15 on the front bar of thc liftingfframe.

A plate or brace, 23, extends from the lower 85 portion of the bar 21 to the under side of the forward end ofthe axle-bearing 20, and greatly strengthens the contrivance. This brace 23 also forms a handle for facilitating in adjusting the block. The forward end ot' the aXle- 9o bearing 2() is cut ont or notched, as at 24, for the purpose of straddling the reach,7 when the jack is -to be used in connection with a vehicle having such a device.

At the upper end of the post A is pivoted, 95 at 25, a lever catch or pawl, 26, which engages with the teeth 14 on the back bar, 11, and which is provided with a handle portion 0r extension, 27, projecting back of the post or standard. To an ear, 28, cast on this extension, is attached one end ot' a chain, 29, the other end of which is fastened to. a foot-lever, 30, piv- IOC) oted at 31n the post. The free end of a curved bar-spring, 32, rests against the under side of the handle portion 27 of the catch 26, and serves to keep the latter in engagement with the teeth 14 during the raising of the liftingbar. The metallic face-plates 3 and 4 are provided with flanges 33, which form a lining for the wearing sides of the slots 1 and 2, and these plates are also provided with perforated extensions 34 and 35, to form washers for the heads and nuts of the pivots of the levers 26 and 30. 36 is a handle for carrying the jack about.

When the parts have been assembled toget-her, as in Fig. 1, the contrivance is ready for operation. The block or support D being placed beneath the axle of the vehicle, the outer end of the lever B is depressed, causing the teeth of the inner portion, e, to move upwardly, and these teeth being always in engagement with the teeth 13 on the back bar, 11, operate to elevate the lifting -frame C and raise the Wheels of the vehicle from the ground.

During the elevation of the lifting-frame the pawl or catch 26 moves in and out between the teeth 14 on the bar 11, and when the depression of the lever B has ceased the pawl will remain in engagement with said teeth and prevent the descent of the lifting-frame.

If the vehicle operated upon be a light one and not raised very high, it may be lowered Without straining or injury by pressing the foot upon'the lever` 30, and through the connection 29 disengaging the pawl 26 from the rack 14, thus allowing the weight of the vehicle to push down the lifting-bar; butif thevehicle be a heavy one, or raised quite high, it is better to keep the hand upon the lever B and let the lifting-bar come down slowly.

If found desirable, the foot-lever may be dispensed with and the pawl 26 disengaged by depressing the extension 27; but I prefer to have both presentin the contrivance. Vhen the pawl 26 is used alone, the lever B should be moved Slightly downward and made to bear the weight of the vehicle, in order to start the disengagement of thepawl, after which thelatter may be easily held disengaged while the lifting-bar and vehicle are descending.

One important advantage in the use of my contrivance is that during all the time the vehicle is held raised the lifting-bar, which supports it, is held up by the pawl 26, and that during the descent of the vehicle the lever B is in engagement with the lifting-bar, and the operatorthusis given such perfect control over the same that he may let the heaviest vehicle down until the Wheels touch the ground without giving it the slightest shock or jar.

By the employment of the detachable support or block D, I am enabled to save time in the lifting of the axles, and also enabled to raise axles'of any height, the block being simply shifted higher or lower, according to the height of the axle, as will be apparent from an inspection of the accompanying drawings.

By reason of the presence of the foot-pieces a and e, the contrivance possesses great stability, and I have been enabled to place the same in the center of the axle and raise both wheels from the floor atoneJ time; and'by reason of the strength of the structure and the arrangements of its parts and the mode of operation thereof, I havebeen able to liftl both wheels of one of the heaviest steam tire-engines' and lower them again with the greatest ease and without giving any shock whatever to the engine. I

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. rlhe combination of the post, the liftingbar provided with the racks 13 and 14 and the toothed bar 15, the lever B, the pawl 26, and the adjustable support D. v

2. The combination of the post, the liftingbar provided with the racks 13 and 14, the lever B, the pawl 26, the foot-lever 30, and a connection, as 29, between the pawl and the footlever.

3. The combination of the post slotted in front and having the slots 1 and2, the liftingbar having the perforated lugs 8 8 and the racks 13 and 14, the pins 9 9, the lever B, and the pawl 26.

4. The combination of the post, the liftingbar provided with the racks 13 and 14, the lever B, the pawl 26, and the adjustable support D, hav-ing the cut-out 24.

Signed at New York, in the county of New York and State of New York, this 18th day of December, A. D. 1886.

HENRY SECCO.
