Improvements in Camera and other Stands Requiring Vertical,
Circular, and Inclinatory Adjustment.
I, FREDERICK TAYLOR, of 11 and 13, Hooper Street, Stockport, in the
County of Chester, Manufacturer of Photographic Apparatus, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improved construction of base and top for camera
or other stands requiring vertical, circular, and inclinatory adjustment, such as
music or reading stands and the like, the object being to render the said stands
simpler, stronger and neater in construction, easier and quicker in adjustment and
firmer in position than heretofore has been the case.
To this end my improved stand base consists of two horizontal discs arranged at
a suitable distance apart from each other, each formed with holes at the circum-
ference to receive short cross rails fitted into a number of legs also formed with
holes. The said discs, spindles and legs being turned ornamentally in appearance.
Through the middle of each of the said discs is formed a vertical hole adapted
to receive the shank, the upper end of which carries the top of the stand. The
said top consists of a table and a circular disc or rim underneatli formed or furnished
with a segmental tongue.
The said top or table is rendered circularly adjustable upon the said disc or
rim by means of suitable brackets fixed to or formed underneath the said table
and adapted to clamp the periphery of the said disc or rim, one of the said
brackets being furnished with a screw or other suitable fastening device for the
purpose of securing the said table circularly in position whereby a whole turn
or any portion thereof may be imparted to the said table. The upper end of
the aforesaid shank is formed with a recess in depth sufficient to receive the said
segmental tongue, a piece in shape partly corresponding with the said recess being
secured to the recessed side of the shank by means of a double hinge and a bolt
having a wing or lever nut passed through the whole so as to permit of clamping
the top or table in any desired inclined position upon the shank. In order to
compensate for the wear which may occur between the said parts and at the same
time retain the said table securely in any inclined position, the inner side of the
upper end of the shank is furnished with one or more rubber studs or discs against
which the tongue of the disc or rim bears. To compensate for the shrinkage of the
said shank when made of wood I secure to the underside of the upper disc of the
stand by means of two bearings a clip rendered laterally adjustable by means of a
wing or other nut so as to permit of drawing the shank against one side of the base
when too loose in the latter and thus prevent the same shaking.

I, FREDERICK TAYLOR, of 11 and 13, Hooper Street, Stockport, in the
County of Chester, Manufacturer of Photographic Apparatus, do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
This invention relates to an improved construction of base and top for camera
or other stands requiring vertical, circular, and inclinatory adjustment, such as
music or reading stands and the like, the object being to render the said stands
simpler, stronger and neater in construction, easier and quicker in adjustment and
firmer in position than heretofore has been the case.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1 & 2 are elevations of a complete camera or the like stand constructed in
accordance with my invention.
Figs. 3 & 5 are plans and Fig 4 a side view of the same detached.
In carrying out my invention and referring to the figures generally I form the
base of the said stand of two horizontal discs a & b arranged at a suitable distance
apart from each other, each formed with holes at the circumference to receive short
cross rails or spindles c & d fitted into a number of legs e also formed with holes,
the discs a & spindles c & d and legs e being turned ornamentally in appearance.
The use of the spindles c & d in connection with the discs a & b and legs e give
great stability to the stand without unduly increasing its weight. Through the
middle of each of the discs a & b is formed a vertical hole adapted to receive the
shank the upper end of which carries the top of the stand. The said top consists
of a table g in connection with a circular disc or rim h the underside of which is
formed or furnished with a tongue i.
g
The top or table g is rendered circularly adjustable upon the disc or rim h by
means of suitable brackets k, k', fixed to or formed underneath the table and
adapted to clamp the periphery of the disc or rim h, one of the said brackets k',
see more particularly Figs. 2 & 4, being furnished with a thumb screw / or other
suitable fastening device for the purpose of securing the table a circularly in
position. On releasing the disc or rim h from the pressure of the screw the
table may be turned completely or only partially round as may be required.
In lieu of employing or forming on the underside of the table g brackets k, k¹ to
reach below the disc or rim h, as described, the table g may be pivotted to the disc
or rim h, as shown in Fig. 4, and a bracket k¹ carried by a bolt fixed to the
table g employed which bracket can be drawn tight against the underside of the
disc or rim by the nut k³.
The upper end of the shank is formed with a recess m in depth sufficient to
receive the tongue i, a flap f' in shape partly corresponding with the recess m being
secured to the recessed side of the shank f by means of a double hinge n and a bolt o
having a wing or lever nut o' passed through a hole formed in the top of the shank f
and the tongue i so as to permit of clamping the same together, and thus secure the
top or table g in any desired inclined position upon the shank f, see Fig. 1. The
double hinge n permits of drawing the shank piece f1 parallel against the tongue i
so as to always ensure a full and firm grip upon the tongue i. In order to com-
pensate for the wear which may occur between the tongue i and the shank f and
permit of retaining the said table at any time securely in any inclined position I may
furnish the inner side of the upper end of the shank with one or more rubber studs

page_text: or discs p, see Figs. 1 & 2, against which the tongue i bears. To prevent the
shaking of the shank fin the holes of the discs a & b, should the same shrink when
made of wood I secure to the underside of the disc a of the stand by means of two
bearings q a clip rendered laterally adjustable by means of a wing or other nut s
so as to permit of drawing or pushing the shank fagainst one side of the base when
too loose in the latter and thus prevent the same shaking.
The shank with the top or table g of the stand may be adjusted in position
vertically by means of a rack fixed to the shank f and a spring bolt to the base,
similar as described in Letters Patent No. 3782, dated March 12th 1888, granted
to me, or by any other suitable means.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is-
"In camera and the like stands."
1st. The base formed of a number of discs and legs connected together by means
of cross rails or spindles, all substantially as and for the purpose set forth.
2nd. The table g in combination with a disc or rim h, the said table being furnished
or formed with means which permit its circular adjustment on the said disc or rim,
all substantially as set forth.
3rd. The rim or disc h, specified in the preceding claim, formed or furnished with
a tongue in combination with the upper end of the shank which has a recess m
and a flap adapted to receive the said tongue and secured in position inclinatory
by means of a bolt o and nut o' all substantially as and for the purpose set forth.
4th. In combination with the shank f, a clip rattached to the base of the stand
and rendered adjustable laterally against the shank f, all substantially as and for
the purpose set forth.

Improvements in Cam and Rack Mechanism.
I, FREDERICK TAYLOR, of 11 and 13, Hooper Street, Stockport, in the County
of Chester, Manufacturer of Photographic Apparatus, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved construction of cam and rack mechanism
applicable for camera stands or other objects which require vertically or otherwise
adjusting in position and has for its object to combine therein rapidity and easiness
of motion.
To this end I form my improved rack with pins or studs in lieu of ordinary teeth
and the cam with a double lift, adapted to engage and leave alternately the said
rack pins or studs. Each of the said lifts consists of a curved rim, preferably semi-
circular, formed eccentrically upon the cam face in lieu of on the periphery, the
ends of which rims pass each other sufficiently, so that when one of the said pins or
studs is about to leave one of the said rims, the other rim is on the point of
engaging the next rack pin or stud. In order to permit the said cam rims of
clearing the ends of the rack pins or studs the cam face is formed slightly conical
or convex and the cam itself mounted at an angle to the rack. The said cam is
rotated by a handle or any other suitable means as may be found most
convenient.

This invention relates to an improved construction of cam and rack mechanism
applicable for camera stands or other objects which require adjusting in position
vertically or otherwise and has for its object to combine therein rapidity, power,
and easiness of motion.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a sectional view and Fig. 2 a back view of my improved cam and rack
motion.
In carrying out my invention and referring to the figures generally I form my
improved rack a with pins or studs b, (in lieu of ordinary teeth) and the cam c
with a double lift, adapted to engage and leave alternately the rack pins or
studs b

page_text: Each of the said lifts consists of a curved rim d, preferably semi-circular in
outline and rounded off ends, formed eccentrically upon the cam face of the cam c,
(in lieu of on the periphery) the ends of which rims pass each other sufficiently, so
that when one of the pins or studs is about to leave one of the rims d, the other
rim is on the point of engaging the next rack pin or stud b. In order to permit the
cam rims d of clearing the ends of the rack pins or studs 6 alternately the cam face
is formed slightly conical or convex and the cam itself mounted at an angle to the
rack a.
The said cam is rotated by a handle or any other suitable means as may
be found most convenient for the purpose for which the motion is applied.
It will thus be seen that during each revolution of the said cam, the said rack is
moved in distance equal to twice the pitch of two pins or studs.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what 'I
claim, is-
A cam and rack mechanism consisting of a cam body with coned face formed
with two cam lifts or rims d in combination with a rack a formed with pins or
studs 6 the said cam lifts or rims being adapted to alternately engage and leave the
said pins or studs and thus move the rack a during each revolution of the said cam
in distance twice the pitch of its pins or studs b, all substantially as set forth.
