present instance, is made of a single casting.
This frame comprises a plate B having a coin-opening a; a block C upon which
the articles to be sold rest; and parallel guides D which are grooved on their inner
faces to receive the operating slide E and delivery slide F.
Gindicates a pawl or dog journaled in the guides D, and provided with two arms b
and c, one, b, extending upward behind the end of the operating slide, and the other, c,
engaging the teeth, d, formed in the delivery slide.
A spring H, secured at opposite ends to the pawl and the operating slide, keeps the
latter normally within the casing; while a spring, I, secured at one end to the delivery
slide and at the other end to a plate J keeps the said delivery slide in its proper
position.
Operating slide E is provided with a coin slot, e, normally in alignment with the
coin slot, a, in the plate B, and in rear of the slot e, it is provided with a plate or
rest, f, against the front face of which the coin will lie flntly.
Delivery slide F is providod with an opening, g, near its forward end, and in
advance of the rest, f, on slide E, it is provided with a lug or stud h, as shown in
Figures 1, 2 and 3.
Projecting inward from the sides of the guides D D are studs K, which may consist
merely of plugs driven to place, or which may be throaded to screw into guides. In
Figure 4 both forms are shown.
The threaded stud will be preferred, however, for the reason that it permits an
adjustment that is not attainable with studs simply driven to place. The projecting
inner ends of the studs may be made angular or smooth and they are so arranged
that when a coin is placed in the slots or openings, a, e, and is resting upon the
plate or rest, its edges will impinge upon the inwardly projecting ends of the
studs. From this construction and arrangement, it will be seen that the coin is
supported upon the studs and that if it be too small it will fall through the
opening down into the money drawer. If the coin be too large, the studs will
not permit it to drop down low enough to engage the lug h, of the delivery slide.

page_text: Now, if a coin of the proper size be passed through the slots a and e, it will fall
upon and be supported by the studs K, the lower edge of the coin projecting below
the upper edge of the lug h of the delivery slide. The coin rest f, which is
slightly inclined, prevents the coin from falling or tipping backward or being
jarred out of place. As the slide E is pulled outward, the lower edge of the coin
strikes against the lng hand of course any further movement of the slide E will
cause a corresponding movement of the delivery slide.
As soon as the outward movement of the operating slide E is discontinued, the
spring H retracts the latter, but as the delivery slide is held against movement by
the pawl or dog, it cannot be retracted until the operating slide is drawn inward
far enough to strike the arm b of the pawl and raise its arm e, out of engagement
with the delivery slide.
When the delivery slide is thus freed, its spring I retracts it and returns it to its
normal position, as shown in Figures 1 and 2.
It will be noticed that when a coin of the requisite size is in proper position, to
connect the two slides, its upper edge will be embraced by the walls of the slot e,
so that when its lower edge strikes the lug h, any tendency to tip forward is
overcome.
The delivery slide has its rear end turned upward as at i, and is provided with a
forwardly projecting plate j, which, as shown in Figures 1, 2, 3 and 4, slides back and
forth over the top of the block C, and is made of a width and thickness suitablo to
the kind of article to be vended.
This plate is guided in its movements by means of grooves which will advisably
be formed by turning up the edges of a plate k secured to the upper face of the
block C.
Plate when designed for use in machines for selling tickets and similar thin
articles, is made quite thin as shown the guiding grooves preventing the springing
of the plate. The plate; forms a part of the delivery slide and partakes of all the
movements of the main body of the latter; and it is obvious that instead of making
the plate separate from the upturned ond of the main body it may be made integral
therewith.
So too, instead of making the upright, i, integral with the main body, it may be
made separate therefrom.
Again, the plate k, may be omitted and the grooves to receive the plate j, made
in the block or support C, but as these modifications fall within the province of the
mechanic they have not been illustrated.
When the delivery slide is retracted by its spring, its upright portion strikes
squarely against the flat end plate J, seated in vertical grooves 1, in the inner faces
of the guides D, as shown in Figures 1, 2 and 5, thereby distributing the jar over
the entire plate J.
By removing the plate J, as shown in Figure 5, the slide F may be withdrawn
from the frame A.
The block is provided at its upper front edge with a forwardly-projecting ledge
or shoulder, which, as shown in Figure 2, will effectually prevent the insertion of a
wire M or the fingers below the lowest card or ticket Z for the purpose of surrepti-
tiously extracting, such card or ticket from the machine.
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 a vending machine, the frame A, for supporting the operative parts of the
machine, and comprising the plate B, the block and guides D, D, the said frame
being made of a single casting, all substantially as shown.
2. In combination with supporting frame having an upright back plate J, the
delivery slide provided with an upright portion to strike against the plate, and an
actuatin slide adapted to be connected with and disconnected from the delivery
slide.

page_text: 3. In combination with a supporting frame and a delivery slide carried thereby, a
removable back plate J mounted in the frame.
4. In combination with frame A grooved to receive the slides E and F, the upright
back plate J seated in grooves in the frame, substantially as and for the purpose set
forth.
5. In combination with a supporting frame, the operating slide mounted therein
and provided with a coin slot, studs carried by the frame and adapted to support
the coin, a delivery slide, and a lug on the delivery slide.
6. In a vending machine, the combination with a supporting frame provided with
two studs projecting inwardly toward each other, of a slide located above the studs
and provided with a coin slot, and a second slide, located below the studs and provided
with a lug or shoulder.
7. In a vending machine, the combination with the two slides E and F, of the
intermediate studs, independent of the slides, adapted to support the coin at its side
edge.
8. In a vending machine, the combination with the two slides E and F, of two
intermediate coin-supporting studs, one of said studs being adjustable.
9. In a vending machine, the combination with the slide E, provided with a coin
slot and with a rest or plate in rear thereof, of a slide F, provided with a lug, and
intermediate coin-supporting studs independent of the slides.
10. In a vending machine, the combination with a frame having a block C, of
a plate k, having bent edges, and a delivery-slide plate ; having its edges seated in
the edges of the plate k.
11. In a vending machine, the block C having an abrupt forwardly-projecting
ledge or shoulder, as and for the purpose set forth.
