Improvements in Store Service Apparatus.
| HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street, Strand W.C. in the County of Middlesex Civil Engineer
do hereby declare the nature of this invention a communication to me from abroad
by The Mendenhall Store Service Company of Cincinnati, State of Ohio, United
States of America 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 Improvements in Store Service Apparatus designed for the
use of store keepers and others and has for its object an improvement in that class of
apparatus. Its novelty will be herein set forth and specifically pointed out in the

The same letters of reference are used to indicate identical parts in all the figures.
Referring to the constructions illustrated on Sheets 1 and 2 the frame work at the
transmitting end is composed of a pendent post A preferably tubular, secured to the
ceiling or other horizontal support, and having attached to it by means of a socket a
adjustable if desired, a horizontal arm B in this instance tubular, in line with and
directly over the way or transporting wire of the usual or any suitable construction
and in this instance secured to a bracket plate D attached to the lower end of the
post A.
It is of course understood that the opposite or receiving end of the way or
wire may be secured to a frame work in all respects the duplicate of that shown and
so far described and to be hereafter described or it may be of any other suitable
construction.
Secure to and extending laterally and downwardly from the arm B are two arms E
with flatened perforated ends in which are journalled small grooved pulleys b.
The basket or parcel receptacle elevator is a rectangular frame composed of two
end bars and two side bars d. Cords e attached to the ends of the bars c pass up
over the pulleys and converging, are attached to or merged into a single cord f

page_text: passed over a single grooved pulley g journalled in a hood or guide housing attached
or clamped to the post A. The lower end of the cord is provided with a grasping
handle in this instance weighted to counterbalance the elevator, and, where found
desirable an eye may be applied to the lower end of said handle to engage with a hook
upon the counter.
By reference to Figs. 10, 13 and 14 the construction of the pulley g and its sup-
porting and guiding hood will be readily understood. The hood as seen in Figs. 10
and 14 is recessed as at j to receive snugly the flange of the pulley g which is made
spool shaped thereby preventing the cord for the four cords e from catching over the
flanges as the elevator is raised or lowered. The lower sides of the hood extend below
the horizontal diamoter of the pulley and their outer edges are bevelled or rounded off
as seen by the broken away portion of Fig. 13 to prevent wear upon the cord or cords
and to more properly guide the same over the pulley.
The carrier frame is composed of a horizontal bar F with bevelled latch hooks k
upon its ends, upwardly projecting lugs between which are journalled grooved
pulleys m resting and travelling upon the wire changers G bevelled and slotted at
their ends to form looks for the automatic attachment and detachment of the basket
by the raising and lowering of the elevator as presently described, and curved
propelling fingers n straddling the wire c for engagement with the propelling springs
as presently described.
The parcel receptacle or basket H may be of the usual or any suitable construction
adapted to be supported and raised and lowered by the elevator frame. I have shown
it as constructed of woven wire and with its sides bevelled or rounded in to make it
smaller at the bottom so as to fit between and be supported by the bars d see dotted
lines Fig. 2 and the bars c are provided with outwardly extending guide plates el for
guiding the basket to its seat in the receptacle.
Secured at each outer end of the basket, at its middle and near the top is a plate o
Fig. 8 from which projects an inclined lug and the lower end of each of the
hangers G of the carrier frame is bevelled off in the direction of the upper side of
the lug so that as the elevator is drawn up with its basket the lugs p come in
contact with the bevelled portion of the hangers and push the latter aside thereby
tilting the carrier on its wire see Fig. 9. An inclined slot is formed in the lower
end of each hanger G constituting with its bevelled underside a hook and a curved
latch S pivoted as at t and with its upper end passed through a slot in a ribu on the
hanger covers the mouth of the slot and projects slightly beyond the point of the
hook. A pin Fig. 4 passed through a slot w in the upper arm of the latch limits
its play. As soon as the lugs p in the raising of the basket have passed the point of
the hook see Fig. 5 they engage with the latches S and the carrier frame being
freed drops back by gravity to a vertical position bringing the hooks under the
lower edges of the lugs p so that by lowering the elevator frame the lugs p slide into
the slots and the basket is thus automatically attached to the carrier see Fig. 4.
The elevator is now lowered from engagement with the basket and the carrier and its
basket are then propelled on the way C to their destination. To detach and lower the
basket it is only necessary to draw up the elevator frame and lift the basket thereby,
until the lugs p have passed up out of the slots thereby pressing asile the carrier
and the latches S until the lower edges of the lugs have passed above the latches
which would drop by gravity over the slots 7 and the end of the hook see Fig. 7.
When the elevator frame and basket are now lowered, the lower side of the lugs p
will bear against the upper inclined sides of the latches S and tilt the carrier to one
side to permit the elevator and basket to descend as will be readily understood. By
means of the flat inclined lugs p and slots q in which they snugly fit the basket
becomes rigidly attached to the carrier and cannot have independent vibration.
As a modification in the construction, reference is made to Fig. 15 Sheet 1 where the
latch S instead of being hooked shaped and pivoted at the lower end of the seat in
the hanger is substantially straight and pivoted at a point above the upper end of the
hook and the lugs p instead of being flat and inclined are simply projecting pins.
The operation is however the same as will be readily understood.

page_text: Instead of having lugs or pins at both ends of the basket to engage with two hanger
hooks, the construction shown in Fig. 16 may be employed where the basket is
provided with a bail having a central lug or pin upon a single hanger and having a
single releasing latch as will be readily understood. While I have provided novel
devices for the automatic disengagement of the basket from the hanger it will be
understood that the means described for effecting the automatic engagement of the
basket with the hanger may be advantageously employed where other devices for its
disengagement are used.
When by reason of small height of the wire way above the counter an elevator is
not required the salesman being enabled to hang the basket or its equivalent direct on
the travelling carrier the elevator above described and the arrangement for effecting
automatic engagement and disengagement of the carrier and the basket are dispensed
with, in this case I may use a circular cup in place of the basket having the con-
struction for engagement and disengagement by hand.
from
In Fig. 19 the supporting ring k for the cup E' is integral with or secured to the
lower ends of the hangers. The cup E' has upon its side, two d'ametrically set
lugs which when the cup is lifted and inserted through the ring, pass through slots
or recesses upon the inner edge of the ring so that when the cup is turned these
lugs travel and rest upon the ring and so support the cup. To prevent the cup
turning while on its way across the wire that part of the ring at the slots is made
higher than the rest, from which points it slants downwards to the hangers so that
when the cup is inserted and turned as seen in Fig. 19 its gravity would prevent its
accidentally returning. In Fig. 18 the ring is made fast to or part of the cup and the
lower ends of the hangers have inwardly extending shoulders to fit under and hold
up the ring and cup. Here the underside of the ring at its highest points is recessed
as at e so that when the cup is turned these recesses are caught and fit over the
shoulders of the hangers. In Fig. 18 the cup is shown just as it is inserted and
before it is turned. Where the ring is upon the hangers it is of course evident
that but one slot may be employed, in which event the cup would have but
one lug.
Whether I use a basket or cup with automatic or hand attachment I use one of the
following constructions to propel the carrier from one end of the way to the other.
I may provide a bell crank latch I Figs. 1. 2 and 11 which is hung on the wire Cand
provided with a grooved pulley a' around which a cord fastened at one end to the
bracket D is passed and extends back over a second groovel pulley c¹ journalled in
the basket and has its lower end provided with any suitable grasping handle.
Springs J of rubber or other material have their rear end's secured to hooked pins d'
Fig. 11 projecting from the latch I and their forward ends to the hooks K Fig. 12
secured to the forward arm E and serve to hold the bell crank latch drawn forward
in engaging position for the hook upon the adjacent end of the bar of the carrier.
This engagement is shown in Fig. 1. Another spring I, having its forward ends
secured to the front arm E engages with the curved fingers n. Upon drawing down
the cord the bell crank I together with the carrier and basket are drawn back
towards the post A and the springs J and L are put under tension until the upright
arm of the bell crank comes in contact with the lower portion of the post A whereupon
the bell crank is tilted and the carrier released. The retraction of the spring L
thereupon propels th: carrier to the opposite end of the line and upon releasing the
cord the retraction of the spring J draws forward the bell crank into engaging
position. The carrier and basket are propelled with sufficient force to effect the
automatic engagement of the former with the bell crank at the opposite end of the
line as will be readily understood.
Or the following construction may be used.
Referring to sheets 34 and 5. A is the usual vertical tubular post secured at its
upper end to the ceiling or other support and having passed through its lower end
and secured to some suitable fixed point one end of the horizontal wire or way C upon
which the carrier and receptacle are propelled. Secured to and extending from the
post A horizontally over the wire C is an arm B having a bearing a" at its extremity

page_text: in which is journalled a vertical grooved pulley 6". In a bearing clamped or secured
to the post A are journalled two grooved pulleys d"ell the former horizontal and the
latter vertical (see Fig. 22) to serve as guides for the operating cord or rope D' which
is passed up over the pulleys d"el and thence forward over the pulley and has
its forward end see Fig. 17 provided with a button, disc or other suitable projection f
which with the forward end of the cord D hangs down just over the wire C as seen
by the solid lines. When the carrier and its receptacle are propelled across the wire
and come towards the apparatus just described the button is caught between the
adjacent forks n which are made longer than for the propelling device before described,
and with the cord D is carried back to the position indicated by the dotted lines and
the spring jaws m¹ which take the place of the latches slip over a head or enlarge-
ment upon the end of the piston rod F of the air cushioning device. Upon giving
the handle a quick pull downwards, the button is suddenly drawn forward against
the forks n of the carrier and the latter is thereby released from the rod Fi and
propelled across the way to a similar or other suitable receiving and returning
apparatus.
It is desirable to have a stop for limiting the stroke of the cord D' and button f¹
and to that end I place a button or knot upon the cord which is arrested by a
slotted or perforated stop piece s preferably adjustable upon the rod B and through
which the cord D' is strung. It is of course evident that the spring jaws m may be
upon the end of the rod F¹ in which event the end of the carrier would have the
enlargement to be caught and engaged by said jaws or again the air cushions might
be applied to the carrier as will be readily understood in which event the spring jaws
might be upon the post or if upon the piston rod the post itself might be engaged or
be provided with an engaging projection.
It is obvious that the propelling device shown principally in Fig. 17 may be used
with the carrier shown in Fig. 1. the latch engagement of the latter being replaced
by the spring clips of the former and the forks n of the latter slightly elongated for
more certain engagement with the button f
The modifications represented in Figs. 20, 23 and 26 consist in the application of
re-setting mechanism to return the button back to the post after the carrier has
been propelled and as soon as the cord is released. In Fig. 20 the cord is extended
back from the button around a guide pulley and up to a spring a whose upper end
is secured as at v¹. In propelling the carrier, the spring u is put under tension so
that as soon as the carrier has been propelled by the quick down pull of the cord D¹
and the latter is released, the button is at once re-set or drawn back in readiness to
propel the carrier again upon its return as will be readily understood.
a
In Figs. 23 and 24 the same result is accomplished by the substitution of a different
form of spring. Here instead of the rubber or coiled spring of Fig. 20 I employ
spring drum Jattached to the post A and around which a sufficient amount of the
rear end of the cord D' is wound and made fast.
The interior of the drum is hollowed out and contains a convolute spring wone
end of which is made fast to the drum and the other to its stationary spindle. The
turning of the drum as the button goes forward to propel the carrier puts the spring
under tension and upon the release of the cord it resets the parts as will be readily
understood.
In Fig. 26 I have shown how a weight may be substituted for the spring to reset
the button.
Here the cord passes back from the the button through a perforation in the post
and around the pulley located in the post thence up over a pulley all in the upper
part of the post and thence downward and has a weight secured to its lower end
within the post.
Slots are cut in the bottom of the post through the apertures o' to permit the
ready insertion of the wire without the necessity of threading the same after which
the air cushioning device and the ornamental plug I are applied. The ends of the
wire extend back and up and are properly secured, after which, and its insertion in
the slots p' the wire is made taut by turn buckles in the usual manner.

page_text: The air cushion device is constructed and operates as follows.
The
Suitably supported at the lower end of the support A is a cylinder G in this
instance by having an exteriorily threaded neck screwed into a corresponding
interiorily threaded neck p" projecting from a ring H" surrounding the lower end of
the support A and secured to the same. Within the cylinder G is a piston q¹!!
having a projecting rod F which passes through coincident holes in the support A and
preferably has an enlarged end n' in line with the carrier F on the way C.
cylinder G has vents for the admission and escape of air both before and behind the
piston one being in this instance the open space in the neck of the cylinder through
which the rod F' loosely passes and the other a hole ¹¹ near the opposite end of the
cylinder. Instead of these venis the vent may simply be around the piston the
latter being made to fit the interior of the cylinder so loosely that it will not
be air tight therein, or for this purpose the cylinder may be approximately air
tight and the piston be perforated the object being to so arrange for the escape of the
air in front of the piston that when a sharp blow is struck on the outer end of the
rod F and the latter is driven into the cylinder the air will at first be compressed
and act as a cushion to receive the jar of the blow but will be permitted to escape
from before the piston so rapidly that there will be no rebound and after the first
shock of the blow the resistance will quickly but gradually yield to the force of the
blow until the latter is exhausted. A spiral spring within the cylinder serves to
restore the parts to normal position but it is not strong enough to offer any material
resistance to the blow which drives in the piston rod. Coperating with this air
cushioning or buffer mechanism are the set of spring jaws m¹ secured to the end of
the carrier F and adapted to engage the enlarged end of the piston rod F' as the
carrier comes in from the opposite end of the way and releasably holds the carrier to
the rod. As the end of the carrier strikes the end of the rod it drives the latter
into the cylinder, the air before the piston receiving the shock of the blow but quickly
escaping through vent tor that around or through the piston, so that the momentum
of the carrier is gradually and easily checked without damaging jar to the various
parts of the apparatus.
As the spring restores the piston and rod to normal position the carrier is
moved with the latter to the position shown by the dotted lines in Fig. 17 and
remains there until the operator pulis the handle of the propelling cord and drives it
to the opposite end of the way.
While I have shown the spring jaws m³ as secured to the carrier and engaging the
end of the piston rod they might be transposed from the carrier to the rod and be
arranged to engage a projection on the carrier in the same manner that they now
engage the end of the rod.
Where a horizontal way is employed as illustrated in the drawing there is a similar
receiving and propelling apparatus at the opposite end of the way. The carrier Fis
therefore provided with two sets of spring jaws and two sets of propelling forks one
set at each end as shown.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is.
