Improvements in Pumps.
We, JOHN WILSON FRASER of the City of London in the County of
Middlesex in the Province of Ontario, Canada, Physician and Surgeon, and JOHN
DOLWAY WILSON of the same place, Physician and Surgeon, 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,
reference being had to the accompanying drawings wherein
Fig. 1. is a side view of a device, illustrating this invention.
Fig. 2. is an end view of same, partly in section, on the line, a, a, of Fig. 1. when
the latter is in about a vertical position.
A, designates a concaved bracket.
B, is a tube, of rubber, or other suitable material, resting therein.
C, C, are boxes; and, D, D, are guides, for holding the tubing in place, and to
prevent its accidental displacement.
E, E, are standards, one on each side of, and secured to the concaved bracket, A ;
each of these standards is formed with an elongated slot, e, through which the
bolt, F, passes, to firmly secure the standards, E, and bracket, A, together.
c, c, are guides, on the bracket, A, on each side of the standards, E, to guide and
hold said standards in a vertical position, when they are being adjusted.
G, is a hub, formed with the trunnions, d, the latter are held in place by, and
revolve perfectly free in sockets in the upper ends of the standards, E, E.
H, is a crank handle, secured to a square outer portion of one, of the trunnions, d,
by which the hub, G, is rotated.
I, I, are arms, rigidly secured to the hub, G, the outer ends, b, of which arms are
forked.
J, designates antifriction wheels, or rollers, pivoted in the forked ends of the
arms, I, as shown.
K, designates a ball, rigidly secured to the bracket, A, which is fitted to, and
inserted in a socket, L, in the bracket support, N, and this bracket support, N, is
cut in two centrally, and clamped together, to readily insert and secure the bracket
in this support.
As shown in the accompanying sketch, this device is provided with a screw
clamp, R, to attach it to an object, but this pump may he attached by any suitable
devices or means to any object, or held in any way, as found most suitable or
convenient under the circumstances.
The slots, e, in the standards, E, permit of the vertical adjustment of the latter, as
well as hub, G, and arms, I, and antifriction rollers, J, connected therewith, this
permits the regulation of the compression of the antifriction rollers on the
tube, B, or relief of the tube, B, from the compression of the roller when not
in use.
And in the accompanying drawings, three arms, I, are shown, but two or more
may be used as required.
In order to obtain the best results from this device, the concave in bracket, A,
should be constructed, so that one of the rollers would engage with the tube before
the preceding one was disengaged therefrom.
This bracket, A, is shown attached to its support, N, by a ball and socket joint,
so that the bracket may be adjusted in any desired lateral position, and a portion, k,
of the ball, K, projects beyond the support, N, so that when clamped to an object,
the action of the clamping screw, will be to rigidly hold the bracket at the position
to which it may be adjusted.

page_text: The operation of this invention is as follows:-
One end of this tube, B, is placed in the fluid required to be lifted, the crank
handle, H, is then rotated, so that the rollers will move along the tube from
said end.
By rotating the crank handle, H, as described, the arms, I, are also rotated, this
brings the antifriction rollers, J, in contact with the tube, B, as shown, and as
these rollers, J, rotate, the tube, B, is compressed, as shown in the sectional portion
of Fig. 2. between said rollers and the concaved bracket, A; and as the rollers, J,
move along said tube, a vacuum is formed therein behind said rollers, into
which the fluid previously referred to, rushes, being acted upon by atmospheric
pressure.
By continuing the operation of the crank handle, H, and rollers, J, connected
therewith, as just described, the fluid continuously euters at one end, and is ejected
at the other end of said tube, B.
This invention has been described in connection with liquid or fluid, but air or
gases could be acted upon in the same manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The concaved bracket, A, and tube, B, in combination with the standards, E,
the hub, G, formed with the trunnions, d, two or more arms, I, provided with
antifriction rollers, J, and means for operating the hub, G, substantially as shown
and described, and for the purpose specified.
2nd. The concaved bracket, A, and the tube, B, in combination with the
standards, E, formed with the slots, e, the guides, c, on the bracket, A, the hub, G,
formed with the trunnions, d, two or more arms, I, provided with antifriction
rollers, J, and means for operating the hub, G, substantially as shown and described,
and for the purpose specified.
3rd. The concaved bracket, A, formed with the guides, D, and boxes, C, and
the tube, B, in combination with the standards, E, the hub, G, formed with the
trunnions, d, two or more arms, I, provided with antifriction rollers, J, and means
for operating the hub, G, substantially as shown and described, and for the purpose
specified.
4th. The concaved bracket, A, formed with the guides, D, and boxes, C, and
the tube, B, in combination with the standards, E, formed with slots, e, the guides,,
on the bracket, A, the hub, G, formed with the trunnions, d, two or more arms, I,
provided with antifriction rollers, J, and means for operating the hub, G,
substantially as shown and described, and for the purpose specified.
5th. The concaved bracket, A, formed with the boxes, C, guides, D, and ball, K,
the support, N, formed with a socket, L, to which the ball, K, is fitted, and the
tube, B, in combination with the standards, E, formed with the slots, e, the hub, G,
formed with the trunnions, d, and two or more arms, I, provided with antifriction
rollers, J, and means for operating the hub, G, and for securing the support, N,
to an object, substantially as shown and described, and for the purpose specified.
