An Improved Snatch and Lead Block.
I, HENRY FRANCIS TALBOT, of 7 Cherry Street in the City of Birmingham,
Patent Agent, 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 improvements in snatch and lead blocks.
Firstly, to provide a safety snatch block single or double by the application of a
lock swivel bar in conjunction and locking both cheeks together securing dispatch
to work and safety to life whilst being used. Also being capable being used with
any other form of pulley forming a safe protection to tackle, from getting unlatched,
until block is actually opened up and tackle taken therefrom.
Secondly, facilitating the work by providing a safety lock swivel bar.
Thirdly, reducing the strain on block and lessening labour time and danger
to life.
Referring to the accompanying drawings
Fig. 1 is a view shewing block opened up ready to place tackle on wheel.
Fig. 2 a vertical section of same shewing design of safety lock swivel bar.
Fig. 3 a view of safety lock swivel bar and snatch block complete.
Similar letters refer to similar parts throughout the several views.
The drawings illustrate my invention which consists of a safety lock swivel bar
snatch and lead block complete, designed as shewn in Figs. 1, 2 and 3 to be manu-
factured of wrought iron, steel, or wood or any other suitable substance in a
substantial manner and consisting of two cheeks, one stationary d forming a back
or base, the other a moveable one fand carrying between them a swivel bar hook k
and also geared with a pulley wheel.
The stationary cheek d centered with shaft a is geared with pulley wheel and
bolted at e, the front part of the shalt is designed with an arm or regulator i with
stop Figs. 1 & 2 to work in conjunction and in segment of circle cut out of
moveable check f. when the cheeks are bolted together the inseth works over the
stop to regulate the rise and fall of the moveable check as shewn by dotted
line Fig. 1.
In the centre near the top or shoulders of the cheek d is the swivel
bar shaft bolted at l.

The bottom of the hook k is designed cast or turned with
an oblong form and pierced with swivel bar shaft q then capped or headed on the
face at n; exactly opposite is designed and cut out in moveable cheek fa hole m
large enough to receive the oblong and allow of its turning therein the cheek fis
also designed with a slut o cut in the side as shewn in Figs. 1 and 3. When the
hook is down as shewn in Fig. 1. the oblong is reversed in position and
horizontally laid, bringing the narrow part of the oblong into position to enable it
to pass up slot o and when hook k is raised exactly in a vertical position as shewn
in dotted lines it brings the oblong i upright in the hole m cut in cheek f, securely
locking both checks d and f together.
To operate block and open same (when locked) drop the hook k to the right as
shewn in Fig. 1, slide the moveable check to the left the narrow part of oblongi
being horizontally laid pass out through slot o which unlocks same as in Fig. 1

page_text: leaving aperture and necessary space, opening up block to place on or remove
tackle.
To lock and use the block place the tackle ou the ropes c onto the wheel b and
raise moveable cheek to the right, bringing as before shewn in Fig. 1 the narrow
part of oblong; up the slot o. Then raise the hook to the left bringing the
oblong into a vertical position in the recess m cut in the cheek f and securely
locking same.
The block is then ready for use and safe for man and beast, for logging, lumbering
and hauling purposes.
I am aware that prior to my invention snatch blocks have been made with safety
appliances in conjunction with logging, lumbering and hauling, I therefore do not
claim such combination broadly.
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:
The combination in a snatch block with a cheek d working in conjunction with a
moveable cheek geared and centered carrying wheel b regulated by inset h and
arm and stop, having hook k. Safe lock swivel, bar (j and g) working and
locking cheeks (f and d) together in hole m through slot o, substantially as shewn
for the purposes specified.
