page_text: WILLIAM PRICE ABELL, Wh. Sc., Assoc. M. Inst. C.E., Castle Hill, Duffield,
Derby, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved form of brake applicable to trucks or bar-
rows of the kind and style used at railway stations for luggage.
It is desirable
1st. That brakes should facilitate the stopping of a truck when in motion with-
out in any way interfering or impeding with the steering.
2nd. That it should be impossible for the attendant to let go of the steering
handle, or leave the barrow without its locking or braking itself.
3rd. That the apparatus be simple and light.
To in part or wholly attain the forementioned, I attach a lever and brake direct
to the handle in such a manner that they form a simple lever round one fulcrum,
such that the weight of the handle brings the brake into contact with the wheels
of the truck, whilst lifting the handle draws the brake away from the wheels. .
I furthermore attain the aforementioned object more completely by the follow-
ing modified arrangement of my invention: In this case I use two fulcrums, in
utilizing the weight of the handle to retain the brake on; I fix a simple lever
having a brake on one end in such a position that either raising or lowering the
steering handle above or below the normal position engages the said handle with
the said brake levers, thereby causing them to press the brake secured to the
said levers into contact with the truck wheels, the said contact being maintained
by the weight of the handle,
Thus by this last modification of my invention when the handle is in a normal
position for pushing or pulling the lorry or truck, the brakes are non-operative,
but immediately the attendant either lets go the handle or puts it out of the
way over the truck, the weight of the handle causes the brake to engage and
retain the wheels.
Dated this 22nd day of October 1898.

page_text: 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 relates to an improved form of brake applicable to hand trucks
or trolleys of the kind and style used at railway stations for luggage, milk churns
and the like.
It is desirable that such brakes should facilitate the stopping of a truck or
trolley when in motion without in any way interfering with or impeding the
steering or general working of the truck: that it should be impossible for the
attendant to let go of the steering handle or leave the truck without its locking
or braking itself; and, that the apparatus be simple and light and facilitate the
handling of ordinary luggage.
.
My invention is designed to attain these advantages and to facilitate the descrip-
tion thereof I have annexed to this specification two sheets of drawings, Figures 1
and 2 of which are respectively a side elevation and a plan shewing one applica-
tion of my invention, while Figures 3 and 4 are respectively similar views shewing
another application of my invention.
In carrying out the application of my invention illustrated upon Figures 1.
and 2 I attach a lever or levers A and brake or brakes B directly to the handle C
the parts of the levers A' working in eyes or bearings 1 the-supports E being
bolted or otherwise secured to the part F, the said bearings being thus set some
little distance forward of the wheel bearings. It will be seen that the weight of
the handle when falling brings the brakes into contact with the wheels of the
truck, the levers and handle forming a simple lever round the fulcrum A¹, while
raising the handle C draws the brakes away from the wheels. A short curved
lever or jack G prevents the said handle being pushed into contact with the truck
table Q whilst also facilitating the work of the men by indicating the proper
line of pull for the handle. In the application of my invention illustrated upon
Figures 3 and 4 I employ two fulcrums H and H' in utilizing the weight of the
handle I to retain the brakes K on the wheels L. I fix a spring lever M to the
lever arms M¹ carrying the brakes K so that by either raising or lowering the
steering handle I above or below the normal position for pushing or pulling the
truck shewn by firm lines on the drawings, either the end of the tongue N or
the underside of the handle at I¹ engages the spring portion of the lever and so
applies the brakes to the truck wheels with a slightly yielding pressure so that
any undue weight on the handle is taken up by the said spring and thus prevents
any breakage due to excessive leverage from goods accidentally falling on the
handle, or from other cause.
The tongue N is fixed to the handle I by means of bolts or the like O passing
through slotted openings P in upward continuations N so that the said tongue N
may be fastened forward or backward to suit the wear of the brake blocks, adjust-
ment of the under part I may be obtained by using washers or other suitable
means as the blocks wear.
Thus by this last modification of my invention when the handle is in a normal
position for pushing or pulling the truck or trolley, the brakes are non-operative,
but immediately the attendant either lets go the handle or puts it out of the
way over the truck as shewn by dotted lines on Figure 3, the part I¹ or the ends
of the tongue N engages the spring M and so applies the brakes to the wheels.
In both applications of my invention the weight of the handle causes the brakes
to engage and retain the wheels.
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 I
claim is:-
1. In a hand truck or lorry for the purposes described the combination of a push-
ing, pulling and steering handle C, levers A A', brakes B adapted to engage
the front whools and

page_text: the whole acting upon a single fulcrum substantially as described, and as
illustrated upon Figures 1 and 2.
2. In a hand truck or lorry for the purposes described the combination of a
pushing, pulling and steering handle I, spring levers M, M' and brakes K adapted
to engage the front wheels L as the handle is raised or lowered above or below the
normal, working level the whole acting upon two fulcrums H and H¹ substantially
as described and as illustrated upon Figures 3 and 4.
3. In a truck or lorry for the purposes described, the combination of a steering
handle and brake with a spring, the said spring being arranged to give way
when undue or excessive weight is brought to bear upon the handle.
4. The adjustment arrangements for compensating the wear on the brake blocks
and trolley wheels substantially as described and as illustrated upon Figures 3 and 4.
