ROBERT HENRY GREGORY, OF CLEBURNE, TEXAS.
COMBINED JACK AND WRENCH.Specification of Letters Patent.
Patented Nov. 18,1913.
Application filed January 11, 1913. Serial No. 741,600.
To alwkognoit may concern:
Be it known that I, ROBERT H. GREGORY,
a citizen of the United States, residing at
Cleburne, in the county of Johnson and
5 State of Texas, have invented a new and
useful Combined Jack and Wrench, of which
the following is -a specification.
This invention relates to a combined
wagon jack and wrench.
10 An object is to provide a lifting jack
whereby the axle and wheels thereon may be
lifted.
A further object is to provide means
whereby 'the axle nut may be removed and
15 the wheel withdrawn from the spindle.
With the foregoing and other objects in
view which will appear as the description
proceeds, the invention resides in the combi-
nation and arrangement of parts and in the'
20 details of construction hereinafter described
and claimed, it being understood that
changes in the precise embodiment of the
invention herein disclosed, can be made
within the scope of what is claimed, with-
25 out departing from the spirit of the inven-
tion.
In the drawings accompanying this speci-
fication and forming a part thereof, the
preferable form of my invention is illus-
30 trated, in which:-
Figure 1 is a view in elevation of my im-
proved jack and wrench, the same being
illustrated as in operative position with re-
spect to a carriage wheel and axle, the lat-
35 ter being illustrated in dotted lines. Fig.
2 is an end elevation of the same.
Referring to the drawings in which simi-
lar reference numerals designate correspond-
ing parts throughout the several views, the
40 supporting frame is composed of the verti-
cal member 1 which is provided- with the'
outstanding feet 2 and a cross bar 3 to which
is- pivotally secured the leg 4, the leg 4 be-
ing provided with the downwardly and out-
45 wardly extending foot 5. The cross bar 3
is held to the member 1 by 'welding or other
suitable means and the frame so composed is
a substantial one, and due to the three sup-
porting .feet is adapted to remain in an up-
50 right position and rest securely on uneven.
ground. The pivoted leg 4 is so arranged'
that it can be folded upward against the
cross bar 3 in which position it is placedwhen putting my combined jack and wrench
into practical use by extending the cross bar 55
and pivoted leg through the spokes of the
wagon wheel.
Pivotally connected to the leg 4 is a
suitable link 4"'which is pivotally connected
to the handle 4'.- Thus by means of the 60
handle 4' and the links 4" the pivoted leg
4 may be.inserted through the spokes of the
wagon wheel in a folded position and. by
suitable actuation of the handle 4' may be
made to assume a vertical and therefore a 65
supporting position, as indicated in Fig. 1.
To the outer extremity of the cross bar 3
is secured a vertical-guide bar 8, the guide
bar being substantially U-shape in cross sec-
tion and is adapted to receive therein a rack 70
rod 9, the edges of the U-shaped guide bar
forming retaining walls between which the
rack rod is adapted to move. The upper
end of the rack rod is enlarged and provided
with a 'forked head 10 which is 'adapted to 75
contact with and support the axle of the
wagon a wheel of which is to be raised and
removed.
Mounted upon the frame member. 1 and
securely held. thereto is a bearing block 11, 80
12. being a similar bearing block in aline-
ment therewith and positioned upon the
outer portion of the cross bar 3, the said
bearing blocks receiving therein a pinion
carrying shaft 13 which -is provided with 85
the crank actuating handle 14 secured to the
outer end thereof. A pinion 15 is rigidly
secured to the remote end of said shaft and
coacts with the rack rod 9 to raise and lower
the latter which will raise and lower the 90
axle of the carriage. Suitable collars are
illustrated-upon the shaft 13 and are adapted
to retain the pinion in active relation with
respect to the rack rod- 9. In order that
the carriage, may be kept in, a raised posi- 95
tion, a suitable ratchet wheel 16 is mounted
securely upon the jack and a. pawl 17 is
pivotally supported thereabove and adapted
to coact therewith.
The portions herein described constitute 100
the jack portion of my improved combined
jack and carriage wrench.
The upper portion of the frame member
1 is bent outwardly as at 6 and provided
with a journaled head 7 in which is slidably 105
and rotatably mounted the wrench shaft 181,078,850.
