A Machine for Rivetting and Unrivetting Fare Receptacles and
the like.
1, ANDREW HOWAT, of 6 Bellwood Terrace, Old Trafford, Manchester in the
County of Lancaster, 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 :-
The object of my invention is to construct a simple and efficient machine for
rivetting and unrivetting as required boxes and like receptacles for passengers fares
and other articles which are locked or secured by means of lead rivets.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a plan and Figures 2 and 3 are end elevations of a machine constructed
according to my invention.
In these views-a is a frame or bedplate on which are formed or secured rails a' to
act as guides for the receptacle to be rivetted or unrivetted: the rails a¹ in this
In brackets bolted to the
instance being adapted for a rectangular receptacle.
bedplate a are secured two stationary dies b and c, the latter being a hollow die, and
two movable dies or punches d and e respectively. Bolted to the bedplate a are two
brackets in which is fitted a shaft g and on this shaft are secured two eccentrics g¹ g²
and a handle h. The strap of the eccentric g¹ is pivoted to the end of the movable
punch & and that of the eccentric g² to the end of the punch e, so that by operating
the handle and turning the shaft g with its eccentrics partly round the punches d and e
can be moved toward or from their respective stationary dies b and c as required.
To the bed plate in front of the hollow die is fixed a finger or projection i and
below the die c there is a slot or opening a² in the bed plate.
When it is desired to lock a receptacle with a lead rivet the former with the lead
rivet in the hasp is placed on the bed plate between the guide rails a¹ and moved into
position so as to bring the extremities of the rivet between the die band punch d:
the handle his then worked so as to compress the ends of the rivet between the
dies b and d and lock the receptacle.
In order to remove the rivet and unlock the receptacle the latter is placed on the
bed plate with its hasp between the hollow die c and its punch e: then by working the
handle the punch e is moved forward and simultaneously cuts off the head of
the rivet and forces it out of the hasp. As the punch e is withdrawn the finger i
catches the washer formed by the punch e passing through the rivet head and draws
it off the said punch so that the whole waste rivet falls down through the opening a²
in the bedplate.
If desired the eccentrics 91 9² may be mounted on separate shafts operated by
separate handles so as to make the movements of the two punches d and e quite
independent one of the other.
The dies b and d may be engraved with any number, private mark or device so as
to imprint the same on the heads of the rivets when locking the receptacles.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
The construction use and application of a machine for rivetting and unrivetting

by separate eccentrics substantially as herein shown and described.
