AUTOMOBILE-JACK.
Specification of Letters Patent.
` Patented May 13, 1919.
Application led May 16, 1918. Serial No. 235,213.
To all whom 'it may concern:
Be it known that I, LOUIS H. BERRY, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Automobile-Jacks, of which the following is a specification. y
This invention relates to that type of automobile jack designed to be permanently attached to the chassis of an automobile and the jack may be operated by the crank provided for the engine of the automobile or may be operated by the tire wrench.
With these and incidental objects in view, the invention consists of certain novel fea.- tures of construction and combination of parts, the essential elements of which are hereinafter described with'referenceto the drawings which accompany and form a part of thisv specification.
Tn'the drawings Figure 1 is a side view of my improved jack with parts broken away, Fig. 2 's a section taken on the line 2-2 Fig. 1 with part of the jack broken away and showing the axle in full, but with the outline of the driving bevel gear shown in the figure, Fig. 3 is an enlarged detail of the means provided forA using a crank to operate the jack andFig. 4 is a section taken on the line 4-4 Fig. 2.
A frame member 1, Fig. 2, preferably of cast steel is supportedat 2 on the chassis of the automobile to which the device-is applied; I' I This frame member is fashioned at 3 into a segment of a pinion and carries a tongue 4 to which is hinged by the bolt orV pin 5- the entire lifting mechanism of the jack.
This lifting mechanism comprises a head 6 having projecting downwardly therefrom a tongue 7 Figs. 2 and 4, the head being hinged by the ears 8 to the pin 5.
Forming a part of, or suitably attached to,
vthe head 6 is plate 14 at its lower end, this entire piece preferably being in a shape of a casting with they bevel gear 12 cast in a core and the nut 14 machine cut.
A screw 15 suitably fastened to the foot 16 carries at its upper end a rack 17, the back face of which is in close relation with the fiat face of the tongue 7.
Carried by the head 6 on a stud 18 on which it is journaled is a bevel gear 19 cooperating with the gear 12.
It is evident that if the gear 19 is rotated it will rotate the bevel gear 12 and the nut 14 forming a part of the same vmember will feed the screw 15 in or out of the sleeve 13 depending upon the direction is turned.
If the bevel gear 18 is turned so as to feed the screw 15 into the sleeve 13 it is also evident that the rack 17 will, toward the end the upward motion of the screw, strike the pinion segment 3 and as the rotation of the bevel gear 19 is continued cooperate there-l with and thus swing the suspended part of the jack upwardly to the left as viewed in Fig. 2.
The jack thus may be ordinarily swung to a horizontal position below the axle 20 which is its normal carrying position, or may-be lowered to a' vertical position and the bevel gear .by the further operation of the bevel gear 19 used to elevate that portion of the chassis from which the jack depends.
Suitably fastened to or forming an integral part of the bevel gear 19is a cup 21 Figs. 1 and 3 through which is passed av `but it is evident that the lshaft 23 may be turned at a considerable angle in any direction with the axis of the cup 21 thus forming a simplified universal joint for the rotation, by ineans of the shaft 23, of the bevel gear 19.
A hanger rear spring 29 attached at 30 to one of the' bolts or any suitable location on i the bolt 22 4 the chassis carries the opposite end of the shaft 23 loosely in the aperture 3l.
Beyond the hanger 29 the shaft 23 carries a head 32 and a pin 33, the head 32 being' fashioned so as to receive'in operative relation the ordinary tire bolt wrench and the pin 33 is adapted to receive in operative relation the crank provided for the engine of the automobile.
It is evident that when the shaft 23 is yturned either by means of the tire wrench or engine crank the bevel gear will be actuated causing the operation of the iaek as hereto described and the shaft 27 will play in the aperture 31, in the hanger 29 to .allow the shaft to assume the necessary angular positions when the jack is swung from a horizontal to a. vertical position and vice versa.
This angular movement of the shaft 23 may be small or large depending upon how close the axis of the bevel gear 19 is in line with the hinged pin between the frame 1 and the head 6, but the construction shown and described will take care of any reasonable alinement between these axes of revollltion.
To prevent the rotation of the screw l5 when the bevel gear l2, and with it the nut 14, is revolved, the tongue 7, Figs. 2 and 4, comes i-n contact with the back face of the rack 17, causing the nut 14 to travel along the screw.
While I have described lny invention and illustrated it in one particular design, I do not wish it understood that I limit myself to this construction, as it is evident that the invention may be varied in many ways within the scope of the following claims:
1. In an automobile jack the combination of a fralne, a pinion sector carried thereby, a head hinged to said frame and having a depending tongue, a sleeve surrounding said tongue and rotatably associated with said head, a nut fashioned in the lower end of said sleeve, a bevel gear fashioned eXteriorly at the upper end of said ing an upstanding screw projecting therefrom, a rack carried by the open end of said screw and adapted to ilnpinge on and co- .operate with said pinion sector dllring a portion of the travel of said screw in respect to said nut and means for rotating said bevel gear.
2. In an automobile jack the combination of a frame, a pinion sector carried thereby, a head hinged to said frame and' having a depending tongue, a sleeve surrounding said tongue and rotatably associated with said sleeve, a foot hav-4 reeaefle head, a nut fashioned in the lower end et said sleeve, a bevel gear fashioned exteriorlv at the upper end of said sleeve`r a tool havv ing an upstanding screw projecting therefrom, a rack carried b v the llpper end ot said screw and adapted to ilnpinge on and cooperate with said pinion sector during a portion of the travel of said screw ill respect. to said nut, and means for rotating Isaid bevel gear, said tongue and said rack heilig.:- so positioned as to prevent the rotation ot' the-said screw.
3. In an automobile jack the combination of a fralne member adapted to be suspended from an automobile chassis, a head hinged thereto and having a tongue depending therefrom, a sleeve rotatably lllollllted with respect to said head and carrying on its upper end a bevel gear alld on its lower end a nut, a screw forcoperating with said nui and having al foot on its lower elld and a rack on its upper elld, said l-aellY beingill close position to said tongue to prevent l'otation of said screw and a pinion seetor eal ried by said frame member and adapted io coperate with said rack near one elld ot the travel of said rack forl the purpose of swinging said head from a vertical to a horizontal position, a second bevel gear eooperating with first bevel gear alld means for driving said secolld bevel gear.
4. In an automobile jack the combination of a frame member adapted to be suspended from an automobile chassis, a head hinged thereto and having a tongue depending therefrom, av sleeve rotatably mounted with respect to said head and carrying on its upper end a bevel gear and on its lower elld a nut, a screw for cooperating with said nut and having a foot on its lower elld alld a rack on its upper end, said raek being ill close position to said tongue to prevellt rotation of said screw and a pinion sector earried by said frame member and adapted to coperate with said rack near one elld of the travel of said rack for the purpose of swinging said head from a vertical to a horizontall position, a second bevel gear cooperating with said first bevel gear alld means for driving said second bevel gear, said means including an extended shaft having a universal joint therein, the free end of which is loosely lullig from a point on the chassis of the automobile to which the jack is applied and being formed at its extrelne end to receive means for rotating said extended shaft. l
