at th will of the operator, may be turned
l) into a vertical position as shown in
Fig. 1.
A weighing device is carried by the rela-
i vly movable secondary member 12 and is
housed within the contour of the relatively
fixed, trough-shaped primary member 8
when the secondary member 12 is closed
down upon the primary member 8, as shown
) i Fg. . This weighing device includes a
retractile, helical spring 19 having adjacent
one end a foot 20. The foot 20, as will be
understood best from Fig. 5 lies in the slot
16 of the lug 14 of the secondary member 12
_i and the pivot element 18 passes through
the foot 20. The pivotal element 18 serves
not only to connect the primary member 8
of the handle with the secondary member 12
thereof but, as well, serves as a point of at-
20 tbhument for the inner end of the spring 19.
The outer end of -the spring 19 passes
through a hole 21 in a bar 22, or is other-
wise connected therewith, the bar 22, as
hill be made evident hereinafter, constitut-
25 ing a weight indicating element, the bar 22
being mounted to reciprocate behind a dial
plate 23 having a slot 24 and secured by
means of screws 25 or the like to the ends of
the lugs 16 and 14 of the relatively movable
30 secondary member 12 which constitutes a
part of the handle. The bar 22 includes a
finger 20 mounted to move in the slot 24 of
the dial plate 23 and adapted to coperate
with a weight scale 27 and a price scale 28,
55 the scales 27 and 28, respectively, being in-
scribed upon the dial plate 23 upon opposite
skdes of the slot 24. The bar 22 passes out-
wardly through the slot 17 in the lug 15 and
is terminally provided with a transverse
40 head 29 to which is pivoted a yoke or sus-
pension member 30.
Presupposing that the parts are positioned
as shown inFig. 1, the operation of the
structure is as follows:-The weight of the
45 block of ice 2 will be transmitted to the fol-
lowin g elements: the jaws 1, the links 4, the.
primary member 8 of the handle 7, the pivot
euleimt .18, the spring 19, the bar 22, the
yoke 20, and thence into the hand of the
50 operator. The spring 19 will yield and the
mdicating finger 26 which constitutes a part
of the bar 22 will move with respect to the
scales 27 and 28 on the dial plate 23, and
thus indicate the weight of the piece of ice
55 2 and the price thereof. To position the
parts as shown in Fig. 2, the secondary
timber 12 of the handle 7 is swung down-
w'rdly, whereupon the head 21 will slide
along the beveled edges 10 of the primary
60 member 8 and interlock with the notches 9,
the bar 22 entering the slot 11a of the end
wall 11 of the primary member 8. When
the head 29 is engaged in the notches 9, the
spring 19 is under tension. It will there-
65 fore be seen that the spring 19 exercises twofunctions: first, when the parts are posi-
tioned as shown in Fig. 1, the spring acts
as a counterpoise, and secondly, when the
parts ae positioned as shown in Fig. 2, the
spring acts as a means for maintaining the
interlocking. parts 29 and 9 in engagement.
When the weighing device is not in use,
as shown in Fig. 2, the same is housed within
the contour of the handle, the secondary
member 12 being closed clown upon the
primary member 8. The device, therefore,
is shielded and protected, and is not likely
to be injured even though the tongs be
thrown about or otherwise handled care-
lessly.
Having thus described the invention, what
is claimed is:-
1. In a device of the class described, a
handle comprising a relatively fixed mem-
ber and a movable member pivoted to the
fixed member and coperating with the fixed
member to form an intermediate grip por-
tion in the handle; a weighing device car-
ried by the movable member and housed
within the handle when. the movable mem-
ber is closed upon the relatively fixed mem-
ber; and a pair of tongs connected with the
relatively fixed member upon opposite sides
of said grip portion.
2. In a device of the class described, a.
handle for tongs, comprising a relatively
fixed member and a movable member pivoted
thereto; a weighing device carried by the
movable member and including a weight in-
dicating element, the weight indicaing ele-
ment and the relatively fixed member having
interlocking parts coacting to hold the mov-
able member closed upon the relatively fixed
member; and a spring connected with the
weight indicating element and constituting
at times, a counterpoise and a means for
holding said interlocking parts in engage-
ment.
3. In a device of the class described, a
handle for tongs, comprising a relatively
fixed member and a movable member; a
weighing device carried by the movable
member and housed in the handle when the
movable member is closed upon the rela-
tively fixed member, the weighing device in-
cludinp a weight indicating element and a
counterpoise spring connected therewith;
and a single pivot element connecting the
relatively fixed member with the movable
member and operatively with the spring.
4. In a device of the class described, a
handle for tongs , comprising a trough-
shaped, relatively fixed member having a.
projection at one end and provided with a
beveled edge located adjacent the projection,
and a relatively movable closure member for
the fixed member, the members being piv-
otally connected; a dial carried by the clo-
sure; a bar mounted to slide adjacent the
dial and having means for registering on the70
