I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows :-
This invention has for its object a buffer which shall prevent the severe strain on
boxes when they are violently pitched out on to a platform on a railway or under any
other like circumstances.
I attach a bracket to each box corner which has sliding in it a projecting knob.
This knob is so arranged as to be pressed out at an angle of 45 degrees or there-
abouts with the sides of the box by means of a pad of indiarubber. The consequence
is when this knob strikes any article the indiarubber is forcibly compressed and
cushions the blow.
The invention can be carried out in various ways. One plan I prefer consists in
forming the bracket with three lugs which are screwed on to the three contiguous
sides of the box. This lug is open at the corner and the open hole has three
embayments.
The knob consists of a cup with three shanks projecting from it, one passing into
each of the embayments of the bracket. The cup is of some malleable metal such
as wrought iron or brass and after being passed into the hole and projecting beyond
it, its three shanks are pressed back into dovetailed recesses in the three shanks.
The dovetails or projecting parts prevent the shanks from being drawn out again
beyond a given point, also the bend of the shanks prevent this. The pad of india-
rubber is forced into the cup and when the cup is at its furthest limit, the india-
rubber projects only a mere trifle or not at all beyond the interior planes of the three
lugs. The indiarubber is also shaped so as to form three planes projecting slightly
above the three planes of the lugs. The result is that when the lugs are screwed on
to the box the indiarubber is somewhat pressed.
The corners can be ornamented in any desirable manner or plated and the knob
itself can have a ball castor in it if preferred.

page_text: Engineer, 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 has for its object a buffer which shall prevent the severe strain or
damage to which boxes or the like are subjected when thrown violently on to a quay,
roadway or railway platform, or when, under other like circumstances, they are
severely handled.
The manner in which the invention may be carried into effect is as follows,
reference being had to the accompanying drawing, in which,
Figure 1 is an elevation showing two adjacent corners of a box with the improved
buffers attached thereto.
Figure 2 is a plan view of the buffer, looking along the axis thereof in the direction
of the arrow in Figure 1, the yielding buffer block being removed.
Figure 3 is a section on line x a, Figure 2.
To each box corner A, is attached a bracket B, preferably by means of three
lugs b and screws 1, the bracket being formed at its corner with a cylindrical or
other suitably shaped socket (, having its axis lying preferably at an angle of
45 degrees or thereabouts with the sides of the box. The bracket B may be of any
suitable form and may be attached to the outside of the box, as shown, or to the
inside thereof, its position being in any case such as will allow the impact knob,
hereinafter described, to project a short distance beyond the box corner at the
required angle.
D is an impact knob which is so arranged as to slide to a limited extent within
the socket C and to project beyond the extremity thereof, being pressed outwards
by means of slightly yielding buffering device such as a pad or block E of india
rubber or other slightly yielding material, or by a spring, which, when the knob
strikes against a platforin or other place, is forcibly compressed and cushions the
blow.
The invention may be arranged in detail in various ways. According to the plan
which is preferred the bracket is provided with three lugs b, as aforesaid, which are
fastened on to the three contiguous sides of the box. The socket opens out at the
junction of the lugs as before described, and it may either be a socket, as shown, or
a mere hole having its walls projecting little, if any, beyond the outer surface of the
lugs. The lugs of the bracket are each provided with a dovetailed recess
embayment 62, which may if desirable be extended into the socket or hole C.
or
The knob D, which is by preference a cup, as shown, has three dovetail shanks d
projecting from it adapted to fit into the three embayments 62. The cup and shanks
are formed of some malleable metal such as wrought iron or brass, and the cup, after
being passed into the hole or socket C, so that it projects a short distance beyond
the latter, has its three shanks pressed back into the dovetailed recesses b². The
dovetails prevent the shanks and the cup from being drawn out through the socket,
and the bending of the shanks also prevents such withdrawal.
The pad E of indiarubber is forced into the cup and when the latter is at its
outermost position, the indiarubber projects very slightly, or not at all, beyond the
interior planes of the three lugs. The indiarubber is also by preference so shaped
as to fit against the corner of the box as shown, and it may also be provided with a
flange or wings e which project slightly above the three interior planes of the
lugs, so that when the latter are screwed against the box, the indiarubber
compressed.
somewhat
The corner brackets can be ornamented in any desirable manner or plated, and the
knob itself may be provided with a ball castor, if preferred.
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, I declare that what I claim is :-
A buffer for the salient corner of a box or other article. consisting of a projecting

page_text: impact knob mounted at a suitable angle upon or in the box corner and capable of a
limited amount of movement to and from the same, and a slightly yielding buffering
device inserted between the inner end of said knob and an abutment on the box,
substantially as described.
