Description

through the flat bottom wall of the cover and threadedly engaging tapped holes in disc 3 i While the form of embodiment of the present invention as herein disclosed constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within th scope of the claims which follow.
What is claimed is as follows:
1. A sear-pin control unit comprising a mounting plate, a solenoid having a stationary core and a magnet winding and a movable armature supported by the plate, a sear-pin having a screw thread connection with the armature and extending through the mounting plate, means including portions of the mounting plate for preventing rotation of the pin, cooperating screw threaded members coaxial with the screw thread connection between the armature and pin, one of said members being rigidly fixed to the mounting plate and the other providing a stop for the armature, means operatively connecting the ar mature with the stop for rotation together and providing for axial movement of the armature relative to the stop, a spring disposed between the core and armature for urging the armature against the stop, the pitch of the screw threaded connection between said members being the same as the pitch of the screw thread connection between the armature and pin, whereby the turning of the armature stop member varies the gap between the armature and the core, while the normal position of the pin relative to'theplate remains unchanged.
2. A sear-pin control unit comprising a base,
a solenoid mounted on the base and comprising v a coil, a core within the coil, a shell casing memher, a sleeve fastened rigidly to said shell casing member, and an armature mounted on the base, a sear-pin having a threaded connection with the armature and extending through the base, means including portions of themounting plate for preventing rotation of the sear-pin, an: armature stop connected with the armature for rotation therewith and having a'threaded connection with the sleeve, the pitch of the threads connecting I the stop with the sleeve being" the same as the pitch or" the threads connecting the armature and. pin, whereby turning the stop adjusts the gap between armature and core while the normal location of the pin remains the same, a spring disposed between the core and armature for urging the armature against the stop, a cover supported by the shell and having a hole coaxial the armature, and a screw-driver slotted part provided by the armature and accessible through said hole.
3, A sear-pin control unit comprising abase, a solenoid mounted on the base and comprising a coil, aocore within the coil, a shell casing member, a sleeve fastened rigidly to said shell casing member, and an armature mounted on the base, a sear-pin having threaded connection with the armature and extending through the base, means nection including portions of the base for preventing ro tation of the sear-pin, an armature stop connected with the armature for rotation therewith and threadedly connected with the sleeve, the pitch of the threads connecting the stop with the sleeve being the same as the pitch of the threads connecting the armature and pin, where by turning the stop adjusts the gap between armature and core while the normal location of the pin remains the same, a spring disposed between the core and armature for urging the armature against the stop, a cover supported by the shell and having a hole coaxial the armature, and a screw-driver slotted part provided by the armature and accessible through said hole, said screw-driver slotted part and the armature stop having cooperating means providing for the rotation of the armature and stop together while permitting axial movement of the armature relative to the core. 4. A sear-pin control. unit comprising a base, a solenoid core surrounded by a coil and an armature mounted on the base, a housing for said solenoid members, a sear-pin screw having a screw threaded connection with the armature and extending through the base, means provided by the base for preventing rotation of the searpin, an armature stop screw having a screw threaded connection with the housing, the pitch of both of said screw-threaded connections being the same, means accessible through a hole in the housing for turning the armature, said armature turning means and said armature stop having cooperating means providing for the rotation of the armature and stop together while permitting axial movement of the armature re1ative to the core, whereby turning the armature adjusts the gap between armature and core while the normal location of the pin remains the same. 5. A sear-pin controlv unit comprising a base, a solenoid mounted on the base and comprising a coil, a core within the coil, a shell casing member, a sleeve fastened rigidly to said shell casing member, an armature, slidably mounted within the sleeve and a spring disposed between the core and armature for urging the armature in one direction, a sear-pin having a screw thread conwith the armature and extending through the base, means including a non-rounded portion of the base for preventing rotation of the sear-pin; and. a stop for the armature, said stop having a threaded connection with the sleeve and operatively connected with the armature for rotation therewith but permitting axial movement of the'armature relative to the stop, the pitch of the threads connecting the stop with the sleeve being the same as the pitch of the threads connecting the armature and the pin, whereby turning of the stop adjusts the gap between the armature and core while the normal location of the pin relativeto the base remains the same.
