`ing'drawings, which form a part of this speciication.
This invention relates to carbon terminals for the armature springs of electric bells and the like, and has for its object an improved holding clip, by means of which the easlly worn out carbon contactbutton is firmly and yet renewably held in place on the tip of the.
spring.
In the drawings Fi'gure l is a perspective of the end of the armature spring with the clip and carbon contact button attached. Fig. 2 is a similar perspective of a slightly modiied form. F1g`s. 3 and 4 are side elevations partly in section of the devices illus.-
trated in Figs. 1 and 2.
A indicates the armature spring Whose end is slotted as at B for the engagement therethrough of the pointed or hooked tip-C is apertured for the engdgement therethrough of the head of the carbon button E, which is preferably, though not necessarily,
ture spring A, by means of t e stud F. The
partially anchored with respct to the 'armaend of the clip member opposite to the hooked spring-engaging end isapertured for the engagement therethrough of the screw G, which engages through a complementarily located and threaded aperture H, in the spring. When the button E hasv been placed on the spring and causedto-engage through the hole in the clip D, the screw G is driven as far into and through the armature spring as is necessary to tightly draw the clip over the slug E, thereby holding 1t in place. f
specification of Letters Patent.
Patented July 4, 1916.
yApplication led March 16, 1914. Serial No. 824,908.
l In the modilied form illustrated' in Figs. 2 and 4, a plvoted pin J is provided for that portion of the clip L intermediate the apern tured end which engagesthe carbon button or slug E and the end carrying the screw.
K; in this form the screw K, instead of being driven into and through the body or' mass of the 'armature spring to effect the drawing of the clip over the carbon slug, is actuated in the reverse direction to cause'a raising of its end of the clip, with respect to the armature spring, and a consequent downward tilting of the'slug-engaging end of the clip.
What I claim is l. In combination with an armature spring, a clip member fulcrumed in spaced relation to one face thereof,'a carbon button interposed between said armature spring and said clip member, and engaging partially through an aperture in said clip member, and a screw member operativelycorrelating said' armature spring and the other end of the clip member from that engaged by said carbonl button, whereby the button vis held in position on said armature spring with the desired degree of pressure.
A2. In combination' with an' armature spring', an apertured clip member fulcrumed thereon, a carbon button resting. upon said armature spring and engaging. through the apertured portion of the clip member, and
.an adjusting screw engaging the free end of the .clip member and thearmature spring,
'whereby thatportion of the clip member engaging the carbon button may be forced tof ward or away from the armature spring, thereby anchoring in position -or releasing the button accordingly.
