Improvements in Tip Carts and Tip Waggons.
I, EDWIN GEORGE SAGE, of No. 54, Shortlands Road, Sittingbourne, in the
County of Kent, General Contractor, do hereby declare the nature of this invention
to be as follows:-
This invention consists of a pin which is attached to the upper portion or body
of a cart or tip waggon and drops into a slot and is held in the slot by a bolt which
is worked by a spring which when pulled out unlocks the bolt and allows the
cart or waggon to tilt with ease and locks itself automatically when the cart or tip
waggon returns to its former position.
Improvements in Tip Carts and Tip waggons.
I, EDWIN GEORGE SAGE, of 54, Shortlands Road, Sittingbourne, in the County of
Kent, General Contractor, 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:
-
My invention relates to an improved locking device for tip-carts and railway
and road tip-waggons and has for its objects firstly to enable the attendant to
unlock the said cart or waggon without endangering his person as hitherto, and
secondly that the said cart or waggon after being tilted and emptied and returned
to its normal position may be automatically locked until required for tilting
again.
My invention consists of a pin or bolt attached to the upper portion or body of
the tip-cart or waggon, which when the said body is lowered into its normal
position automatically enters a slot in a device fixed upon the lower frame of the
vehicle, the said device having a rod and plunger operated by a spring, which said
plunger automatically engages with a slot or hole in the said pin or bolt and so
locks the said lowered body, and when required the vehicle body may be unlocked
from its frame by the withdrawal of the said plunger from the said pin or bolt,
suitable means being provided for locking the said plunger when so withdrawn, in
order that the attendant may release his hold thereon, and transfer his labour and
attention to the tilting of the body of the vehicle in the usual way.
In order that my invention and the several manners of employing the same for

page_text: the purposes stated, may be understood I have hereunto appended two sheets of
drawings in which,
Figs. 1 and 2 Sheet 1, are vertical central sections of my improved locking
device, illustrating the two positions of this when in use for locking and unlocking
respectively the pin or bolt in connection with the body of the vehicle, Figs. 3
and 4 being sections upon the line A B of Fig. 1 and CD of Fig. 2 respectively.
Figs. 5 and 6 are side elevation and plan respectively of the pin to be fixed upon
the body of the vehicle, and which engages with the device Fig. 1.
Fig. 7 is a smaller view illustrating the manner of using Figs. 1 and 5 in
duplicate in connection with tip carts as hereinafter explained, and shewn by
Fig. 8 Sheet 2, which is a perspective view of the front of such a tip-cart.
Fig. 9 Sheet 2 is a perspective view of so much of a railway tip-waggon, while
Fig. 10 is a perspective view of so much of a road tip-waggon as will serve to
illustrate the application of my invention thereto.
Fig. 11 is a perspective view of another form of locking device, the principle of
construction of which is the same as Fig. 1, but adapted for use in connection
with rig. 10.
In so far as relates to its application to tip-carts and railway tip-waggous, I
carry my invention into effect by casting or otherwise producing from any suitable
metal or combination of metals, entire or in one or more parts, screwed or otherwise
connected to each other, a device as at Fig. 1, consisting of a cylindrical portion A,
having an internal passage a, the upper end of which is narrowed to form a
shoulder b, and above this has a narrow rectangular slot c, the lower end of A being
extended into a rectangular formation at A', and theat provided with a
rectangular passage or slot d, and has a flange e by means of which it may be
bolted or screwed where required.
The passage a receives a rod B, the lower end of which is extended in diameter
to form a plunger f, adapted to fit freely within the passage a, while the upper
end of B takes a rectangular formation in cross section at B₁, adapted to fit freely
within the slot c, and carries a handle C, adjustable upon the portion B¹, by the
means of a pin, screw, or its equivalent h, engaging with one of a series of holes j
in B¹.
A spiral spring D surrounding the rod B is placed within the passage a, one
end of which abuts against the plunger f, while its opposite end abuts against
the shoulder of A, the power of the said spring serving to push the plunger
through cinto d as far as permitted by the handle C, adjusted by the pin h.
In adapting my invention to tip-carts such as Fig. 8 in which the shafts E and E¹
form a frame upon which the body is pivotally fixed at its back end, (not shewn) so
that by raising the front of the said cart the contents may be shot out behind, I
fix a pair of the devices as previously described, one upon the inner sides of each of the
shafts E and E, and facing each other, and coinciding with the slots d in each of
the devices so fixed, I screw, bolt or otherwise firmly attach to each of the usual
extensions F upon the body of the cart, a pin or bolt G, constructed substantially
as at Figs. 5 and 6, each being of such shape and dimensions in cross section as to fit
freely within the slots d in the said fixed devices, the fore ends of each of the said
pins or bolts having a slot or hole k, formed therein, while its extreme point is
tapered or pointed at 7, so that when the fore part of the cart is lowered, the said
portions would enter the slots d and pass below the rounded ends of the plungers f,
thereby forcing the latter farther into the passages a, against the tension of the
springs D, and when the body of the cart has reached its lowest position resting
upon the shafts E and E', the pins or bolts G would be in such a position within
the slots d of the respective devices, that the plungers of would engage with the
slots or holes k in the said pins or bolts G, and so automatically lock the body of the
cart to E and E.
In order that the carman or attendant may be able to release both the said locked
pins G simultaneously (when the cart has to be tilted) without placing his person
in dangerous proximity to the heels of the animal, I provide a rocking lever m,

page_text: pivotally mounted at a point p upon the usual cross or binding rail H, of the cart,
and to the said lever m is connected, above and below the point p, the one ends
of two rods, cords, or wires J and J¹, the opposite ends of which are connected to
the handles C, of the locking devices respectively, so that a pull imparted to the
upper end of m, would release both pins or bolts G simultaneously and to effect
such pull for the purposes stated I connect to the upper end of m a rod K, which
extends through a hole r in the shaft E', at the near side of the vehicle, and
is thereat provided with a handle C, and this end of K is extended in diameter
to form a shoulder K¹, so that when K is pulled to release the pins or bolts G, the
said widened part of K would be brought outside the hole r which permits that this
end of K may be lowered until the said shoulder K¹ abuts against the Ed of the
hole and so lock this and the withdrawn plungers f, that the carman's hands
may be free to manipulate the tilting of the cart in the usual way. The position
of the apparatus upon the cart will be understood by reference to Fig. 8 and the
manner of its operation more clearly by reference to Fig. 7.
Referring to Fig. 9. In adapting my invention for use upon railway tip waggons,
I fix one of the said locking devices upon that side of the frame L of the waggon
from which the body L' is raised, while upon the frame of the said body I fix one of
the pins or bolts G, in such a position, that when the said body is lowered, the
said pin enters the slot d in the locking device, and is therein retained in the
manner previously described. In this arrangement the pin or bolt G would be
released by a pull upon the handle C, until the plunger was clear of the bolt G,
and the wider part B₁ of the rod B withdrawn from the passage c when by giving
one quarter turn to the handle C as at Fig. 2 the part 1 would be placed crosswise
of the passage cas at Fig. 4, thus holding the plunger f clear of the slot d while
the attendant raises the body L' and shoots out its contents.
Referring to Figs. 10 and 11. In adapting my invention for use in connection
with tip waggons used upon the road in which the body M is slid along the frame N
of the vehicle before tilting, I construct the said locking device as at Fig. 11, the
only difference between this and Fig. 1, being that in this device the tubular
portion A is at the side of 'A' instead of upon the top of the same as at Figs. 1
and 2. For the purposes of this arrangement the said device Fig. 11 is fixed upon
the upper surface of the iront portion of the frame N, while the pin or bolt G (also
slightly altered in formation to adapt it for use in this arrangement) is fixed upon
the front of the body M, so that when the said body is pushed along the frame N
into its normal position after being tilted, the said pin or bolt G enters the slot d
and is therein locked in the same manner as in the previous arrangements, the
unlocking of which by the carman would be effected by a pull upon the handle C,
which may be operated outside of N by extending the length of the rod B¹ that
this may pass through a guide P, fixed upon the near side of the said frame as at
Fig. 10, or if desired, a rod such as K K₁ C₁ (previously described) may be connected
to the handle C of the locking device and extend through the guide P as may be
found most convenient.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. The herein described device and the several methods of constructing and
using the same singly or in duplicate for automatically locking tip-carts and
railway and road tip-waggons substantially as herein set forth and shewn by the
accompanying drawings.
2nd. In a locking device for tip-carts and railway and road tip-waggons the
combination of a pin or bolt such as G, fixed upon the body of the vehicle, and
adapted to fit freely within a slot or aperture such as d in a device fixed upon the
shafts or equivalent frame of the vehicle, the said device consisting of a flange e
carrying a tubular extension such as A, in which slides a rod BB₁ carrying a
plunger f and handle C, the said plunger being adapted to engage with a hole or

page_text: slot k in the said bolt or pin G, by the tension of a spring such as D, with means
such as the partial rotation of B for locking the plunger f when withdrawn from k
in G, substantially as and for the purposes herein described and shewn.
3rd. As a means for operating simultaneously a pair of the devices set forth
in the preceding claim, the combination of a pair of rods, cords, or wires, such as J
and J, connected to the handles C of each device, and to a rocking lever m,
mounted at a point upon the cross stay H of the vehicle, the said lever being
operated by a pull upon a rod or the like K, with means such as a shoulder K¹ for
locking the same when so pulled, substantially as described and shewn, more
particularly by Figs. 7 and 8 of the accompanying drawings.
