PROVISIONAL SPECIFICATION.
Improved Ground Anchor for Guiding Steam Scoops and the like.
JOHN EDWARD BROWN, Alton, Hampshire, Contractors Agent, do hereby
declare the nature of this invention to be as follows:-
:-
An anchor with tynes that shall engage and draw into the ground for use with
steam scoops or other impliments to guide the samo by means of ropes or chains
passing round a snatchblock pulley mounted under a return extension, jointed
to the anchor frame and held in position by a catch lever, but upon this lever
being withdrawn the pulley and extension turn over and release the rope or
chain.
The tynes may be fixed, or at pleasure made to swing backwards to release them
from contact with the ground by removing the pauls for holding them in the
proper position. The tynes also swing forward for convenient form of trans-
portation.
Improved Ground Anchor for Guding steam scoops and the
I, JOHN EDWARD BROWN, of Alton, in the County of Hampshire, Contractors
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 a ground anchor provided with tines that engage and
draw into the ground for use with steam scoops or other implements to guide them
by means of ropes or chains passing round a snatchblock pulley.
One object of my invention is such a connection of the tines to the frame of the
apparatus that they can be readily withdrawn from the ground when required
and that the whole implement can be readily moved from place to place. I also
arrange the snatch block in such a manner that it can be readily released from its
fixing so as to free the rope or chain. I shall describe a ground anchor according
to my invention referring to the accompanying drawings.
Fig. 1 is a side view of a ground anchor according to my invention,
Fig. 2 is a plan.
The frame of the implement consists of two side bars A A which are at a distance
apart in front and nearly meet at the rear, being held by cross stays B B. On
the front ends of the bars A are pivotted the tines O C, on each of these tines is
pivotted a pawl D which when engaged against a shoulder 6 of the bar prevents
9.71

page_text: the tines from turning forwards on their pivots and so losing their hold on the
ground. But whon the pawls D are released leaving the tines free to turn, then
they can be drawn out of the ground by pulling the implement backwards. Tho
tines can be turned quito back as indicated by the dotted lines C' so as to lic
beside the side bars A A with their convex fronts resting on the ground like
sledge runners, in which condition the implement can be drawn like a sledge. H
is a shackle attached to the rear of the frame to receive a rope or chain for hauling
the implement along the ground.
The snatch block pulley E is mounted on the under side of a bar F the one end
of which is pivotted to the rear end of the frame, and the other end passes through
a slot in the lover G which is also pivotted to the frame. On pushing forward the
lever G so as to release the end of the bar F the pull of the rope or chain on the
pulley E causes it and the bar F to turn over backwards thus entirely freeing
the rope or chain from the pulley.
Obviously, a snatch block having its pulley mounted on the under side of a
pivotted bar such as F which is held or released by a lever such as G, might be
adapted to ground anchors or fixings of other kinds.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A ground anchor constructed and operating substantially as described with
reference to the drawings.
2. A snatch block for a ground anchor or other fixing having its pulley mounted
on the under side of a bar, which is pivotted at one end and has its other end
held by or released from a lever, substantially as and for the purpose set
forth.
