the metal pot; Fig. 4 is an elevation showing
the galley and the ejecting mechanism for
handling the slugs to be melted; Fig. 5 is a
horizontal section upon the line 5-5 of Fig.
5 3, looking ii the direction of the arrow, and
showing how the ejector plate is operated by
aid of a bell crank lever for the purpose of
ejecting the slugs; Fig. G is a fragmentary
elevation somewhat similar to Fig. 4, but
10 showing the device as operated in connection
with a comparatively wide galley and wide
ejector plate, for the purpose of operating
upon slugs of greater length than those ap-
pearing in Figs. 1 to ") inclusive; Fig. 7 is a
15 horizontal section upon the line 7-7 of Fi g. 3,
looking in the direction of the arrow, and
showing how the pot feeder is adjusted for
slugs of different lengths; Fig. S is afrag
mnentary vertical section through the galley
20 containing the slugs to be melted; and Fig.'
9 is a detail showing how certain movable
parts are automatically disconnected in order
to prevent breakage in case a slug becomes
fastened and is not easily dislodged from the
25 galley.
At 7 is a galley having generally the form
of a tall box. The galley is provided with
a door S connected with it by hinges 9 and
provided with fastenings 10 whereby it may
30 be temporarily secured in closed position.
At. 11 are shown the slugs which are to be
melted up. The galley is removable and is
provided at its bottom with a slug stay 12
of the form shown in Fig. 6. This slug
35 stay is simply a plate having a curved handle
13 and extending through slots 14, 15 so as
to support the slugs 11. When the galley is
off the .machine the slug stay prevents the
slug from dropping out of the bottom of the
40 galley. When the galley is placed within
the machine the operator grasps the handle
13 and withdraws the slug stay.
The door S and the back of the galley 7
are provided with peep holes 16, 17 to enable
45 the operator to see the slugs in the galley
and thus ascertain when the galley needs re-
plenishing. A pair of angle strips 18 are
fitted with metallic ways 19 (see Figs. 3, 4),
and connected with these ways are clips 20
50 bent toward each other, as will be under-
stood from Fig. 5. These clips are provided
with inwardly extending bearing arms 21.
L-shaped brackets 22 are connected with the
clips 20 by aid of bolts 23.
55 At 24 is shown an ejector plate which fits
slidably into the ways 19 and is adapted to
reciprocate.
The ejector plate 24 is provided with a
projecting portion 25 carrying a pin 26. A
60 bearing 27 of substantially U-shape fits over
this pin and is carried upon the lower end of
an arm 28. This arm is journaled upon a
pivot rod 29 and is integral with an arm 30.
The arms 28, 30 may be considered as a bell
65 crank lever. As this lever rocks upon thepivot rod 29, the ejector plate 24 recipro-
cates in a horizontal plane, ejecting the slugs
11, one at a time, simply pushing them out
edgewise, the lower end of the galley being
adjusted far enough above the angle strips 70
18 for this purpose. These slugs drop
through an opening 31 into the metal pot 32
and are melted up.
Brackets 33 are mounted upon the clips 20
and are provided with portions 34- extending 75
horizontally therefrom. Bolts 35 extend up-
wardly through these portions. Brackets
36 are mounted. upon opposite sides of the
galley and engage the bolts 35, the weight
of the galley thus resting upon these bolts. so
The height of the galley above the angle
strips is thus controllable by aid of the bolts
35, and different thicknesses of slugs thus
allowed for, as C(sired. When the operator
wishes to change the thickness of the slugs, 85
he turns the screw bolts 35.
As shown in Fig. 6, the device may be em-
ployed in connection- Pih wider galleys,
so as to accommodate slugs of greater
length. In Fig. G the galley is shown at 7, 90
and except as to width is exactly like the
galley 7 shown in other views. The pivot
rod 29 is provided with set collars 20a held
rigidly but detachably in position by aid of
set screws 29". In order to substitute the 95
galley 7a for the galley 7, the latter is lifted
out and the galley 7a put in place as shown
in Fig. 6. This is easily done by moving the
angle strips 1S farther apa rt as hereinafter
described, setting the collars 2"9a in new po- 100
sitions and replacing the ejector plate 24
with a wider ejector plate 24a. The arm 30
is journaled to a rod 37. The angle strips
18 support the weight off the melting pot
32, and brackets 1Sa are secured upon these 105
angle strips by aid of fastenings 18h. These
brackets partially encircle a stationary arm
1S moimted upon the framework.
It will he noted that the pivot rod 29 is of
sufficient length to extend a little distance 110
through the bearing aims 21 so as to permit
the ready adjustment of the collars 29 where
longer slugs are to be used. It will also be
noted that the ejector plates 24 aie easily
removed and other plates 24a substituted for 115
them, as will be understood from Fig. 3.
The bearing 27 is easily raised off the pin 26
by lifting the arm 30 a sufficient distance
11wardcl. The upper end of the rod 37 is
provide] with a slot 38 extending obliquely 120
downward as indicated in Fig. 9. The rod
37 is also provided at its upper end with a
leaf spring 3a bent slightly outward from
the rod 37 and normally closing the outer
opening of the slot 38. The arm 30 carries 125
a pin 38" which is adapted to slip into the
slot 38 by pressing the upper end of the
spring 35: slightly away from. the upper end
of the rod 37. This rod is further provided
with a rounded or beveled surface 38c, the 1300
