page_text: LETTERS PATENT to Alexander Horace Brandon, Civil Engineer, of
No. 13, Rue Gaillon, Paris, for the Invention of "AN IMPROVED
CARRIAGE LIFTING JACK."-A communication by Noël Victor Dominique
Barbou, Locksmith, also residing No. 13, Rue Gaillon, Paris.
Sealed the 4th June 1867, and dated the 14th January 1867.
PROVISIONAL SPECIFICATION left by the said Alexander Horace
Brandon at the Office of the Commissioners of Patents, with his Petition,
on the 14th January 1867.
I, ALEXANDER HORACE BRANDON, Civil Engineer, of 13, Rue Gaillon,.
Paris, do hereby declare the nature of the said Invention for "AN IMPROVED
CARRIAGE LIFTING JACK," to be as follows:-
This machine consists in one or more stationary uprights, over which I
adapt a sliding sleeve, and between the uprights surrounded by the sleeve I
insert an upright movable bar fitted with teeth on one of its faces and con-
nected to the sleeve by a spring pawl or other analogous mechanism in such
a manner that when the sleeve is raised or lowered by means of a lever or
other agent the upright toothed bar will also be raised or lowered, whilst the

page_text: said bar can be raised independently of the sleeve by lifting with the hand
and lowered again by its own gravity by simply disengaging temporarily the
pawl from the teeth cut on the side of the said bar.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Alexander Horace Brandon in the Great Seal Patent Office
on the 11th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
HORACE BRANDON, of No. 13, Rue Gaillon, Paris, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Ratent, bearing date the Fourteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alexander Horace Brandon, Her special licence that I, the said Alexander
Horace Brandon, my executors, administrators, and assigns, or such others
as I, the said Alexander Horace Brandon, my executors, administrators, arid
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED CARRIAGE LIFTING JACK," being a communication from Noel
Victor Dominique Barbou, Locksmith, also residing No. 18, Rue Gaillon,
Paris, upon the condition (amongst others) that I, the said Alexander Horace
Brandon, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months-next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Alexander Horace Brandon,. do
hereby declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked-thereon (that is to say) :-
This machime consists of one or more stationary uprights, over which is

page_text: adapted a sliding sleeve, and between the uprights surrounded by the sleeve
is inserted an upright moveable bar fitted with teeth on one of its faces, and
connected to the sleeve by a spring pawl or other analogous mechanism in
such a manner that when the sleeve is raised or lowered by means of a lever
or other agent the upright toothed bar will also be raised or lowered, whilst
the bar can be raised independently of the sleeve (by lifting it with the hand)
and lowered again by its own gravity by simply disengaging temporarily the
pawl from the teeth cut on the side of the bar.
Fig. 1 is a lateral sectional elevation of one kind of lifting jack, the rack
bar alone being raised; Fig. 2 is a front elevation of the same; Fig. 3 is a
lateral sectional elevation, the sleeve and rack being both lowered; Fig. 4 is
a lateral elevation with the sleeve and rack raised together, but with the rack
still at the bottom of the sleeve; Fig. 5. is a lateral elevation of the jack above
mentioned with certain modifications, and Figures 6. and 7. are details belonging.
to the latter Figure.
The improved jack is formed of a base plate a; which can be made either
of wood or metal, and to which are attached. two upright standards b, b, and
around these standards is passed a metallic sleeve e capable of sliding on the
same, and provided at its lower extremity with a tongue or barf sliding freely
between the two standards and resting on the short end of an actuating lever c,
which turns on a pin d fixed in the uprights. Between the two uprights is
placed a rack or lifting bar which rests on the tongue f when lowered (see
Figures 2 and 3) but which can be raised and suspended at different heights
within the sleeve by a pawl h attached to a fulcrum i fixed in the ring g which
encircles the sleeve, and the teeth of which are caused to gear into those of
the rack by means of a spring k. It will thus be seen that the apparatus
consists of two separate moveable parts, the sleeve and the rack, so arranged
that they can be raised and lowered independently one of the other or
collectively. In practice the rack is first lifted separately by hand, being in
contact of the object to be raised, and is maintained in that position by the
pawl h (see Fig. 1), and then the long arm of the actuating lever c is depressed,
whereby the shorter arm raises the sleeve and the rack with great power;
these parts can afterwards be brought to their former position by first raising
the lever c and then disengaging the pawl from the rack, whereby the latter.
will fall to the position indicated in Fig. 3.
Figures 5, 6, and 7 represent one of these racks embodying three different:
modifications, the first of which consists in covering the upper or lifting part
of the rack with a soft material in order not to injure the parts with which it

page_text: 9.
comes in contact; for this purpose it is covered with a piece of leather which
is secured by means of two side plates s, s, attached to the rack by the rivets
or screws r, r.
The second improvement consists in providing the pawl h with a shank h³,
whereby it is more easily manipulated.
And the third improvement consists in attaching to the back part of the
sleeve e a double spring p for the purpose of more securely retaining the
lever c when raised, and preventing its falling accidently.
Fig. 8 is a sectional front elevation of a modification of the jack above
described; Fig. 9 is a sectional side elevation; and Fig. 10 is another front
elevation.

This machine differs from the one above described in its structure rather
than in its principle or mode of operating. To the base plate a are adapted
two uprights b, b, which can be united to the same by being passed through
this plate and rivetted on the under side, and in this case the two plates a¹ and
a serve to protect the wood and consolidate this structure; these. uprights
are arranged so as to receive the lifting bar edgeways, instead of sideways
as in the previously described jack. A sleeve e is passed over these uprights
and an actuating lever c placed at the base in the separate bearings b¹, b',
and its short arm is divided in the shape of a fork, so as to come in contact
with the two sides of the sleeve. The lifting bar is suspended at any
required height in the sleeve by means of a pin passed through the
corresponding hole in the bar, and either attached to a spring blade ", as
in Figure 8, or to a small lever n² hung on a centre n³, and maintained in the
required position by a spring k, as in Figure 10; or both the spring blade and
lever may be dispensed with and the pin suspended by a small chain to any
convenient part of the sleeve. In order to limit the motion both of the
sleeve e and the bar 7, and to prevent their being detached, a stop is adapted
to each of these parts; for the sleeve this stop consists of a screw p tapped
into the same with its extremity projecting within a slot cut in one of the
uprights b, the length of which slot corresponds with the extent of motion
imparted by the actuating lever c; for the lifting bar a plate u is attached by
a screw u¹, which limits the elevation of the bar by its coming in contact with
the shoulder u².
Having thus described the nature of the Invention, which has been com-
municated to me by my foreign correspondent, and having explained the best
means with which I am acquainted for putting the same into practice, I
claim as the Invention secured to me by Letters Patent as aforesaid, the

page_text: combination and arrangement of parts above described, constituting an
improved carriage lifting jack.
In witness whereof, I, the said Alexander Horace Brandon, have here-
unto set my hand and seal, the Twenty-second day of June, in the
year of our Lord One thousand eight hundred and sixty-seven.
