arch-shaped.- 'I'he U-_shaped detent means 55-has
legs 51, 58 with which the arch-shaped bight.56
merges. The inner periphery of the bight 56 of
the detent means `55 is in general ~registry with
the upper portion of the apertures 53, 54. _The
arch-shaped bight 56 of the detent means 55 is
provided at its top with Aa protuberance 59, which
in this instance is of approximately semi-'cylin
drical form, struck up from the bight -56, the axis
of the protuberance 59 being at right angles to the
15 axis of the arch 56 and at right angles to the
_axis oi’ the aperture 28. The protuberance 58 isv
normally above the arcuate margins 44, 45. The
'upward movement of the detent means 55 is lim
ited by `shoulders 66, 6 Lextending inwardly from
20 near the upper ends of the walls 25, 26, somewhat
below the junctions of the walls 25, 26 with the

projections 62, 63 extendingl outwardly from the
sides'of the arch ¿56, the upper ends of these
25 projections 62,P 63 beingwadapted to abut the
shoulders 66, 6I. The projections 62, 63 may
be struck out from the arch 56.

tubular body of the post I4, below the detent
which these terminal posts are insertable. .The
provides an `intermediate portion- 11 overlying
the bridge 29 and disposed between the walls
22 and 25. The insulating plate 14 also'overlies
the feet 46, 41, 48, 48, 50, 5I. If desired a.
spacer 18 may be provided between the plates
52, 14, of approximately the thickness of the
before-mentioned feet, the spacer being pro
vided with an aperture 19, generally-outlining
the feet of such terminal posts as maybe mount
ed on the base. The parts of the composite base
I8 may be held together bya metallic channel
88, having flanges 8l, in which the plates 52. '
x14, and the spacer 18, if used, are disposed, vthe
ilanges 8| of the channel 88 being provided with

posts I3, I4 or any other similar posts.
Inv Figure -4 is shown a conductor terminal 83 'ì
in cooperative relation to the aperture 28 of the `
terminal post I4. The protuberance 59` of the
detent means 55 is in engagement with an an
25

-It will be noted that when a conductor termi

spring 69, disposed within the tubular body of
the terminal post I4, the other end of the spring
engaging the inside surface of the bight 65 of
the detent means 64, thereby biasing the detent
means 64 against the lower ends of the legs 51,
50 58 of the detent means 55 and biasing the detent
means 55 against the shoulders 60, 6I.
A detent means 16, slldably positioned in the
tubular body of the post I3, `is cooperable with
the aperture 24 and a conductor terminal ln
sertable therein. 'I'he detent means 18 is, in this
instance, identical with the detent means 66 ex
cept that it cooperates with the aperture 24
formed by the loop 23 instead of cooperating
what from its position shown in Figure 2, by 45
insertion of the conductor terminal 83. Also,
the detent means 55 has moved the detent means
64 downwardly a small amount, the protuber
ance 68l being however still above the lower
margins ofthe apertures 53, 54. In this posi
tion of the parts the lower ends of the legs 51,
58 of the detent means 55 are stillI in abutment
`with the top of the bight 65 of the detent means
