THE COLLIERY GUARDIAN.

January 5, 1917.

pulleys 10, 11 and 12, 13 mounted in recesses of the block
(fig. 4), and over two pulleys mounted in the head of grab
frame (fig. 1). The free ends of these cables are attached ait 16
to a crane cable or the like, and to two fixed points of the
grab frame. The pulleys 10, 11 and 12, 13 are fixed in 'the
block. The pulley 13, however, is supported according to
the invention by a small .slide block 17 vertically adjustable
in a recess 18 of the block, in opposition to the action of a
spring 19. The bolt 7 is provided with an elongated recess
20, and co-operates with a second bolt 21. The latter is
rotatable, and is arranged in the block 9 transversely of the
bolt 7, and provided with such a recess that, according to
the position of the bolt 21, the bolt 7 can freely move up
and down in a recess 8 of the slide block 9, or be locked by
the bolt 21. The bolt 21 is provided at one end with a collar
engaging with a recess in the upper half B oif the upper
slide (block 9. A portion of the collar is cut away, so that a
stop 23 is formed for the end of a vertical locking pin 24
arranged in the plane of the collar,: and guided in a bore in
B. The other end of the pin 24 is secured to a lever 25,
one end of which is pivoted at 26 to the upper slide block 9,
whilst the other end. is pivoted to a pin 28 screwed into the
block 17. To the end of the bolt 21, opposite the end carry-
ing the collar 22, is secured a lever 29, carrying at its free
end a balance weight 30. The end of the lever 29, secured
to the bolt 21, is provided with a projecting flange broken at
one point. A rotation of the bolt 21 produces a correspond-
ing rotation of the lever 29, necessary space, being recessed
in the block 9. According to' the position of the bolt 21, a
pawl, pivoted to the lower slide block 5, and controlled by a
spring secured to the same block, is brought into engage-
ment with the end- of flange. In order to give the
lever 29 a slight upward turning during, the descent of the
block 9, for the purpose of bringing the pawl into engage-
ment with the end of the flange, on the lower slide block 5
is mounted a bolt 40, with a projection 39, and provided at
both sides with a roller 41 or 42. During the movement of
the slide blocks 9 and 5 these rollers are forced to move
along guides designed so that the projection 39 of the switch,
which can slide to and fro in a guide 45 secured to the slide
block 5, is brought at, the right moment .into and out of the
path of the balance 'weight 30. An excessive rotation of the
lever 29, as well as of the pawl under the action of the spring,
is Prevented by a screw or the like. (Three claims.)

102247. Improved Automatic Cable Stopper for Use with
Winches and Winding Drums. P. L. Hochon, of 80, Bue
de Courcelles; and N. Gjorgjevitch, of 5, Impasse de la

Defense, Paris, France.—
Belates to a device for
stopping cables, particu-
larly adapted for use with
winches. The drawing is a
side view. The device con-
sists of a block 27, carry-
ing a movable jaw 28,
pivoted at 30, the jaw being
acted upon at its. end 29 by
a spring 31, which presses
the end 29 outwardly, and
tends to hold . the jaw
pressed inwardly against the
cable 24 -passing between
said jaw and block ,27.
The block 27 is slidably
mounted on a rod 26,

21-



mounted behind the drum 7 on a plate 3. The cable 24, on
the winding-off side of the drum 7, is left free to travel in
the direction x as its free end is pulled in that direction. If,
however, the free end of the cable is released, and the cable
is pulled in the direction y by the load, it will be gripped
between the movable jaw 28 and the block 27. As the
block 27 can slide laterally on the pivot 26, the whole device
can always be in line with the free end of the cable, no
matter what number of turns of cable are on the drum.
(Two claims.)

CATALOGUES AND PRICE LISTS RECEIVED.

Cravens’ Patent Limited.—Catalogue W 53 enumerates the
remarkable range of trucks manufactured by this company,
from the ‘ Colossal ” platform truck to the bullion truck for
bankers. Scores-of designs show how varied are the indus-
trial uses of this necessary adjunct of business. Baskets,,
hampers, and step-ladders are included in the multifarious
lines illustrated in this booklet.

Chicago Pneumatic Tool Company.—Embodying a great
mass of experience, the company is producing the “ Giant ”
low-grade fuel oil engine, which is calculated to meet the
demand for an engine capable of withstanding the severe-
usage to which.such engines are liable. “ Bulletin 34—W ■ ”
describes the construction and explains the method of work-
ing. Most of the common crude oils and fuel oils in use
are included in the guarantee, and records of many “ Giant ”
engines are available, showing the small cost of obtainingr
say, 50 horse-power. “ Bulletin 263 ” contains an interest-
ing account of. the Boyer railway speed recorder.

William Asquith Limited.—The substantial and handsome
form in which this company describes and illustrates its
range of drilling machines is quite in keeping with the
quality of Asquith machine tools. The whole energies of
the works in. Halifax are devoted to modern drilling and
boring machines of various types, with the result that the
most widely different requirements are met. From such a
mass of machines it is impossible to single put salient lines
for special reference. The letterpress and illustrations
occupy 136 large pages, and a pictorial idea of the various
activities is conveyed by fhe views of the interior of the
works.

CALENDARS.

W. H. Willcox and Company Limited.—This South-
wark-street firm has issued a handy date remembrancer,,
which is doubly useful for its primary purpose and for its
illustrations of the many stores needed in engineering works.

James Light and Son, Liverpool.—In its neat tabulation
of dates in blue ink—relieving the crimson lettering of the
firm’s own announcement—‘this hang-up calendar will be
acceptable to the firm’s many customers, to whom a compact
form of reference for days and dates is always essential.

Simon-Carves Limited. — Literature has been laid under
judicious foil in compiling a calendar, the cream glaze and
gold lettering of which will brighten the dingiest wall, as
the precepts in their waiy will brighten the commonest intel-
ligence. The calendar is suitable for the best-appointed
office.

Maxa Limited.—The three-monthly diary (suitable for the
vest pocket) of Maxa Limited is so useful that we are pleased
to find that it receives due recognition. The company, dis-
tributes 7,500 copies to customers throughout the United.
Kingdom, all. of whom are users of “ Maxa ” as a preserva-
tive of all kinds of belts and ropes.

The British Aluminium Company Limited (109, Queen
Victoria-street, London, E.C.) has prepared a hang-up
calendar, to which the hackneyed terms of neat and artistic
can be applied With justice. The dam at Kinlochleven forms
the subject of a striking picture of Scottish scenery. The
company’s “ Boll of Honour ” on the back of the calendar
shows how great has been the response to the call of king
and country.	'

Haslam and Stretton' Limited.—A charming departure
from the stereotyped' style of calendars has been effected by
this Cardiff firm, of engineers’ agents and merchants, who
have reproduced by colour photogravure “ Annabel ” from
the original pastel of Mr. J. Boss Bryson. This is a work
of art, and the calendar portion is attached so judiciously
that it does not detract from the appearance of the picture
on a wall. “ Annabel ” is distinguished among the many
seasonable productions of the press.

Donetz Coal in 1917.—At the recent Congress of South
Bussian Mining Industrialists a report on the coal production
in the Donetz Basin included an estimate of the production
in 1917, namely, 2,082,000,000 poods, of which 1,647,000,000'
poods is common coal, and 535,000,000 poods anthracite.

Hull Coal Exports.—The official return of the exports of
coal from Hull to foreign countries for the, week ended
December 26 is as follows :—Fecamp, 948 tons; Harlingen,
685 ; •Honfleur, 1,511; Bouen, 8,596; Treport, 570 — total,:
12,310 tons. Corresponding periods December 1915 and
1914—totals, 26,661 and 40,704 tons. These figures do not
include bunker coal, shipments for the British Admiralty,
nor the Allies’ Governments.

Partnerships Dissolved.—The London* Gazette announces
dissolution of the following partnerships :—Albert Halstead,
Arthur Halstead, and G. H. Halstead, trading as Henry-
Halstead and Sons, nut and bolt manufacturers, Sharples-
street, Blackburn; D. H. Morton, A. Home-Morton, W. A.
Ker, and G. H. Leckie Gibson, trading as Home-Morton,,
Ker and Gibson, consulting engineers, 153, St. Vincent-
Glasgow, and 2, Eldon-street,'London, have dissolved part-
nership, and have formed two separate firms.
