UNITED STATES CHARLES O. RYBERG, OF BROCKTON, MASSACHUSETTS.
VEHICLE LIFTING JACK.
Application filed March 5, 1927.
The object of this invention is to provide as a motor Vehicle adjunct, a lifting attachment comprising a holder and a jack, the holder being adapted for attachment to an axle without change or adaption of the latter, and the ack being hinged to the holder, so that it may stand in a vertical position beside the axle, and be operated to raise and lower the latter, and may also stand in a substantially horizontal stored position when not in use.
The invention is embodied in the improved construction hereinafter described and claimed.
Of the accompanying drawings forming a part of this specification,
Figure 1 is a side view of an attachment embodying the invention, in its operative position, portions being shown in section, and a sectional view of an axle to which the attachment is secured.
Figure 2 is a view similar to Figure 1, showing the jack in its inoperative position and means for supporting the jack in said position, a portion of the jackbeing broken away.
Figure 3 is a section on line 3-3 of Figure 1.
Figure 4 is a section on line 44 of Figure 1. v
Figure 5 is a section on line 55 of Figure 1.
Figure 6 is a side View, showing a motor vehicle equipped with a plurality of attachments, one end of the vehicle being raised.
Figure 7 is a front end view of the vehicle and shows the two attachments secured to the front'axle the jacks being adjusted to raise the vehicle.
Figure 8 shows in perspective the holder hereinafter described.
The same reference characters indicate the same parts in all of the figures.
The holder element of my improved attachment is composed of a body portion 17 a clamp adapted to engage an axle 20, and a hinge member which includes spaced apart ears 23. The clamp includes a shank 18, projecting from the body portion, and a clip 19, forming with the shank, a clamp adapted to embrace the axle, as shown by Figures 1 and 2, and be rigidly secured thereto, without change or modification of an axle of the standard cross-sectional form here shown. The clamp and hinge member Serial No. 172,994.
project from opposite sides of the body portion 17, and the arrangement is such that the body portion and hinge member project from one side of the axle, and the hinge member'is located higher than the axle, so that when the jack hereinafter described is swung to a horizontal position, a portion of the jack may extend over the axle without contacting with the latter.
The jack element of the attachment includes a head. or frame, composed of spaced apart tubular guides 14 and 15, and a neck 16 connecting and offset from the guides. The guide 14 is hinged to the cars 23 of the holder by pintles 24, inserted in orifices 25 in the ears and screwed into tapped orifices in the guide 14, as shown by Figure 4.
The jack element also includes a threaded standard 12, movable endwise in the guides 14 and 15, and provided with a foot 33, and mechanism for longitudinally moving the standard relative to the head, to elongate and contract the jack. Said mechanism includes a nut 27, engaged with the standard and having a toothed circular periphery, the teeth 29 of which constitute a bevel gear, and an operating shaft 32, journaled in the neck 16, and provided with a bevel gear 31, meshing with the nut gear and cooperating with the guide 14 in confining the nut against sidewise movement. In this instance, the gear 31 holds the nut against a ball bearing 28, interposed between the nut and the guide 14.
Rotation of the standard 12 with the nut is prevented by means embodied in a longitudinal slot 36, in the standard 12, and a spring-pressed pin 37, movable in the guide 15, and projecting into the slot. The location of the hinge ears 23 at one side of, and higher than the axle, enables the jack to be moved to a substantially horizontal stored 'position, as shown by Figure 2, without contacting with the axle.
The foot 33 of the standard 12, which bears on a supporting surface when the jack is adjusted to raise thevehicle is, in this instance, a Wheel, loosely rotatable in bearings 34, fixed to the lower end of the standard. The wheel constitutes a rollin foot adapted to bear on a supporting surface and cause elevation of the vehicle when the jack is elongated, and permit transportation of the vehicle when it is raised.
, The jack may be supported in its stored position by a hook 38, suspended from the vehicle body, as shown by Figure 2, and engaging an eye 39, fixed to the standard.
To confine the jack in a vertical position, I provide the holder with a locking member 22, fixed to and projecting from the body portion 17, and provided with a striking face 42 and a socket 4:1 (Figure 2). The jack head is provided with a spring-pressed looking member or pin, movable in the guide 15, and engageable with the fixed member 22, by a movement of the jack to a vertical position, the jack head being automatically locked when the jack is in its operative position.
The jack standard 12, the frame 13, and the nut 27, constitute the preferred embodiment of a longitudinally extensible and contractible jack structure supported by the rolling foot 33, and adapted to be interposed between a supporting surface on which the foot bears, and a vehicle above said surface. The shank 32, the gear 31, and the gear teeth 29 on the nut, constitute the preferred embodiment of means for extending and contracting the structure to raise and lower the vehicle.
I believe myself to be the first to combine with a longitudinally extensible and con tractible jack structure, and means for extending and contracting the same, a rolling foot supporting the jack structure and arranged to bear on a. supporting surface and permit transportation of a vehicle raised by the jack.
I am not limited, therefore, to the preferred embodiment of the invention shown by the drawings, except as otherwise required by certain of the more limited claim hereto appended.
I claim:
A lifting attachment for vehicle axles,
- comprising a holder composed of a body a jack including a head composed of spaced apart tubular guides and a neck connecting and offset from said guides, one of the guides being hinged to the hinge member of the holder, a threaded standard movable endwise in the guides, mechanism for longitudinally moving the standard relative to the head, to elongate and contract the jack, said mechanism including a nut engaged with the threaded standard and having a toothed circular periphery, constituting a bevel gear, and an operating shaft journaled in the neck and provided with a bevel gear meshing with the nut gear and cooperating with one of said guides in confining the nut against sidewise movement, the standard and one of the guides being provided with means for preventing rotation of the standard with the nut, the arrangement being such that the standard may be moved to a vertical supporting position beside the axle, and to a substantially horizontal stored position higher than and extending crosswise of the axle, and locking means for confining the jack head when the standard is vertical, said means including a locking member fixed to and projecting from the holder, and a complemental springpressed locking member carried by the jack head and engageable with the fixed member by a movement of the jack to a vertical position, so that the jack head is automatically locked.
In testimony whereof I have aflixed my signature.
CHARLES O. RYBERG.
