Improvements in and relating to Indicating and Registering
Apparatus.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in and relating to indicating and
registering apparatus.
The practical use of the accessory recording device described in the Specification
of the British Patent Application No. 1350 dated January 19th 1895 has led to the
hereindescribed improvements for throwing out of action the said accessory
recording device or for bringing it back into its position of zero respectively.
In order that the invention may be readily understood I will explain the same
by way of example in referring to a definite vase, for instance, to a public chair to
be let by the time and provided with a principal indicating apparatus and an
accessory recording device.
When such a chair is occupied its principal indicating apparatus will be auto-
matically set in motion, for instance, in turning down the movable chair-seat, hy
means of a cam or the like suitably attached to one of the journals or pivots of the
said chair-seat. The said cam being adapted to act upon the principal indicating
apparatus so as to release or to stop its clockwork according to the respective
lowered or raised position of the chair seat. As soon as the principal indicating
apparatus is stopped a suitable connecting link depended upon this being thrown
out of action of the latter will cause the pointer of the accessory recording device
to dart back to its original (zero) position. In such an arrangement the throwing
out of action of the principal indicating apparatus and of the accessory recording
device therefore takes place contemporarily with the turning up motion of the
chair seat.
In many cases, however, it may be desirable to make the throwing out of action
of the principal indicating apparatus entirely independent of the chair scat or its
being raised or turned up respectively. For this purpose the principal indicating
apparatus may be provided with a suitable stop-motion adapted to be covered or
guarded by the lowered chair seat so that the said stop-motion is not accessible
and can but be operated after the chair seat has been raised or turned up again.
The return movement of the accessory recording device will be effected in this
case by means of a suitable spring presser or the like connected with the said
accessory recording device and adapted to be operated upon by the chair seat as
BOON as the latter is caused to pass from oue position into the other, that is to
say on lowering or raising the said chair-seat as it may be required by the special
ustruction. In such an arrangement the return movement of the pointer of the
accessory recording device which return movement is effected by the aid of suitable
means influenced by the principal indicating apparatus or influencing the latter
respectively is thereby made temporarily independent of the throwing out of action
of the principal indicating apparatus.
Although I have in the foregoing described the nature of the present invention

page_text: by way of example in connection with a chair I wish it to be clearly understood,
that the invention may be also applicable for other articles of use the employment
of which is intended to be controlled.

Improvements in and relating to Indicating and Registering
Apparatus..
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 comprises improvements in and relating to indicating and
registering apparatus of that class in which an indicating and registering device is
combined with an accessory recording device for special or exceptional services or
events, which accessory recording device is dependent upon the throwing out of
action of the other principal apparatus for indicating and registering successive
events of the same kind.
This class of combined apparatus in which the throwing out of action of the
principal apparatus and of the accessory recording device as well as the darling
back or return movement of the pointer of the accessory recording device to the
zero position take place contemporarily is fully described in the Specification of
former British Patent No. 1350:dated January 19th 1895.
The practical use of such combined apparatus has led to further improvements
which consist in the peculiar combination of the principal indicating and registering
apparatus with the accessory recording device; the object of the improvements is
to make the throwing out of action of the principal apparatus entirely independent
of the throwing out of action of the accessory recording device and of the moving
back of its pointer into the zero position so that in such au improved arrangement
the return movement of the pointer of the accessory recording device, which
return movenient may be effected by the aid of suitable means, is thereby made
temporarily independent of the throwing out of action of the principal indicating
and registering apparatus..
.
In order that the invention may be readily understood I will describe first the
known arrangement and combination of a principal indicating apparatus with an
accessory recording device by way of example in referring to a definite case, for
instance, to a public chair to be let by the time and provided with both the said
apparatus, and then I will explain in contradistinction to this the novel improved
arrangement and combination of such apparatus also in respect of a chair to be let
by the time, in order to show clearly the difference and nature of the present
invention.
In the accompanying drawings:
Figure 1 is n side elevation of a public chair, showing the general arrangement
and known combination of the principal indicating apparatus in connection with an
accessory recording device.
Figure 2 illustrates the mechanism for contemporarily throwing out of -action
the said principal apparatus and the accessory device.
Figure 3 is a front view,
Figure 3 is a similar view, with the front plate removed to show the interior,
Figure 4 a lateral elevation and

Figures 10 and 11 are lateral views of a chair provided with my improved
indicating and recording apparatus, said views.illustrating the co-operation of the
latter and of the seat.
Figure 12 is a detail view representing the spring presser for the accessory
device.
Similar letters refer to similar parts throughout the several views.
When a chair constructed according to Figures 2-5 is occupied its principal
indicating apparatus A, which is usually actuated by clockwork will be auto-
matically set in motion, for instance, in turning down the movable chair-seat b, by
means of a came or the like suitably attached to one of the journals or pivots a of
the said chair-seat. The said cam e being adapted to act upon the principal
indicating apparatus by means of a sliding piece o acting upon a stop-lever
influenced by a spring (Figure 3) so as to release or to stop the clockwork of
the said principal indicating apparatus according to the respective lowered or
raised position of the chair seat. As soon as the principal indicating apparatus A
is stopped a suitable connecting link i resting upon the stop lever q and dependent
upon this being thrown out of action of the apparatus A will disengage the ratchet
pawl of the accessory device B (this position of the parts being shown in
Figure 34) and thus cause the pointer p (Figure 3) of the accessory recording
device B to dart back to its original (zero) position, from which position it has
been brought by the pusli-knob c when recording the accessory events. The push-
knob c to wit, when pressed down, turns forward by its arm r, forming a sliding
pawl, the ratchet wheel upon the pointer shaft, thereby moving the pointer p of
the latter over the dial plate accordingly. The pointer p or the ratchet wheel
is arrested in the respective position. (after the push-knob o has been released) by
the said ratchet pawl until the latter is disengaged by the link i as already
described. When turning forward the ratchet wheel bends or cocks a spiral
spring and it is this latter which turns back the wheel, pointer shaft and pointer p
as soon as the ratchet pawl is disengaged.
с
In such an arrangement the throwing out of. action of the principal indicating
apparatus A and of the accessory recording device B therefore takes place
contemporarily with the turning up motion of the chair seat b. This is all clearly
described and shown in the Specification of the said former British Patent No. 1350
of 1895 and needs therefore no further explanation as the above description will
be fully understood by any one skilled in the art and trade of indicating and
registering apparatus.
The present invention relates to improvements in indicating and registering
apparatus of the above mentioned class and the object of my improvements is, as
.already stated above, to make the throwing out of action of the principal indicating
apparatus ▲ entirely independent of the chair seat b or its being raised or turned
up respectively. For this purpose the principal indicating apparatus A may be
provided with a suitable stop-motion (Figures 7 and 7*) adapted to be covered
or guarded by the lowered chair seat b (Figure 10) so that the said stop-motion *
is not accessible and can only be operated by a suitable key or the liko after the
chair seat has been raised or turned up again (Figure 11). The stop motion may
consist for instance of a square headed shaft & carrying a toothed wheel d
(Figure 7) engaging with a sliding rack so that the latter when moved along by

page_text: turning the said shaft k acts with its inclined extremity f¹ upon the sliding
piece o in order to raise or lower the latter respectively, whereby the principal
indicating apparatus is thrown out of action or set in motion accordingly as already
above described.
.
The return movement of the accessory recording device B will be effected in
this case by means of a suitable spring presser or the like connected with the said
accessory recording device and adapted to be operated upon by the chair seat bas
Boon as the latter is caused to pass from one position into the other, that is to say
on lowering or raising the said chair seat as may be required by the special
construction. The presser advantageously consists of a spring actuated sliding
bolt connected with the recording device B and guided and arranged preferably
in a suitable side parts of the chair so that the outer rounded or wedge shaped
extremity of this bolt projects into the path of the scat b. When the seat is
turned up or down it will strike against the presser bolt and sliding along on one
of the inclined surfaces of the wedge shaped extremity it will cause the presser
bolt to slide aside in the direction of its longitudinal axis. By this sliding
movement of the presser bolt a cain-piece attached to the inner end of the
presser bolt (Figures 74 and 12) is brought under the ratchet pawl in order to
disengage the latter (Figure 74) from the ratchet wheel r for the purpose stated
above. In such an arrangement the return movement of the pointer of the
accessory recording device which return movement is effected by the aid of
suitable means influenced by the principal indicating apparatus or influencing the
latter respectively is thereby made temporarily independent of the throwing out of
action of the principal indicating apparatus.
Although I have in the foregoing described the nature of the present invention
by way of example in connection with a chair, I wish it to be clearly understood,
that the invention may be also applicable for other articles of use, the employment
of which is intended to be controlled.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, 1 declare that what I claim is :-
1. In an indicating and registering apparatus comprising a principal indicating
apparatus and an accessory recording device meaus for bringing baok the latter
into its zero position temporarily independent of the throwing out of action of the
principal indicating apparatus, said means being designed to act upon or being
actuated by the principal indicating apparatus; substantially as and for the purpose
specified.
2. In an indicating and registering apparatus comprising a principal indicating
apparatus and an accessory recording device means for bringing back the latter
into its zero position temporarily independent of the throwing out of action of the
principal indicating apparatus, which means consist for the principal indicating
apparatus of a suitable stop motion adapted to be covered or guarded by a movable
part of the article of use, the employment of which is to be controlled, and for the
accessory recording device of a spring presser adapted to be operated upon by the
Baid movable part, substantially as and for the purpose set forth.
3. In an indicating and registering apparatus comprising a principal indicating
apparatus and an accessory recording device the combination of a stop motion k
and a spring presser or the like I with a movable part of the object to be controlled,
substantially as and for the purpose described.
