En che embodiment o ouiu inventm as {512M-ae@ and whimhcws apfefsrred conn 10W s. L. buf:
[L d and piave ae "Loo homer is Bravi@ the center of the solenoid, and in this Way the retarding force would be suliicient to limit the stroke of the plunger. The length of the magnetic cores could be adjusted properly to eliminate the buffer springs 8 and 9, but, however, it is preferable to use the butter springs also.
Fastened to the plunger' 7 is an upright,
projection or operating rod 12,' which is adapted to reciprocate with said plunger 7. A switch arm 13 is mounted in a suitable manner upon the top of the casings for the magnets by means of screws 14; which pass through elongated slots 15 in the switch arm 13. r he projection or operating rod 12 passes through a slot 16 in the switch arm 13.
Mounted on the ends of the switch arm 13 are contact lingers 17 and 18 which are adapted to connect to contacts 19 and 2G fastened on the casings 4l of the solenoids A and B respectively. The switch arm 13 is preferably constructed of insulating material, and is preferably mounted upon blocks of insulating material in order to thore oughly insulate the contact fingers 17 and 1S from the casing of the magnets A and B.
lt will be understood that while We have shown and described a particular ,form of switch, we do not wish to be understood to limit ourselves to the. particular forni' of switch shown. We have simply constructed and described this form of switch to illus-- trate more clearli7 the principle of the op eration. Other rorrns of switches could of course readily be applied.
The operation of the device is as follows: rlhe current passes through wire 21 to wire 22 as shown by the connection 23. The wire is connected to the contact .finger 17 on the switch arm 13. The current then passes through the Contact finger 17 to the stationary contact 19 suitably insulated from. the casing of the solenoid A.. .From the contact 19 the current passes through the wire 24 which is 'connected to the coils of the magnet B, as shown. When the current passes through the coils of the solenoid B, it
linnnediately cnergzes said solenoid and dran/'s the core of plunger 7 into said solen noid B quickly and with considerable force, thereby imparting motion to the end of the tool holder and to whatever it may be connected. The other end of the coil in the solenoid. B is connected to wire 25, to which is connected :it 25 the wire 27, which is the return Wir-e of the circuit. Thus a complete circuit is formed. Now when the plunger 7 has been drawn into the solenoid. B the upwardly extending projection or operating rod 12 is drawn with said plunger, and upon reaching the end of the slot 16, draws said switch arm 13 along with it until it has broken. the connection between the linger 17 and the stationary contact 19 en the solenoid A. Upon breaking the circuit at this point, it immediately makes a connection between the Contact linger 18 and the stationary contact 20 upon the solenoid B. As soon as this connection is made, the current which passes in through wire 21 flows through the Wire 22 to the linger 1S instead of the linger 17, and through the stationary contact 2O to wire 28. The wire 23 is connected to the coil l of the solenoid A, and thereby cnergizes the solenoid A which immediately draws the plunger back into the solenoid A, the current passing from said solenoid A to the wire 25 and thence to the wire 27 as before. As the plunger 7 is returned, the operating rod. 12 reaches the other end of the slot 16 in the switch arm 13, and connects the contact finger 17 and the stationary contact 19 together, as before, and this operation is continuously repeated, thus automatically energizing the solenoids A and B alternately, and imparting a reciprocating motion to the plunger 7, thereby operating whatever it is found desirable to operate by said plunger 7. ln Fig. 3 we show the plunger directly connected to a hammer tool which'may be of any desired type. rlhe solenoids A and. B are suitably mounted in the casing 29 of the hammer tool and the core 7 is suitably coupled at 31 to the tool 30, thereby imparting a reciprocating movement thereto.
lOur device can readily be modified in construction without departing from its spirit and scope, and we do not wish to be confined to the exact details of construction shown.
We claim:
ln combination with two solenoids and supporting means therefor and a plunger lyingI within the fields of both oi them and rectilinearly reciprocated by thein as they are alternately energized, a switch comprising a bar and mountings for said bar on the supporting means of the solenoids whereby said `bai` lies parallel with said .ylunger and is movable parallel with said plunger but to a lesser extent, said bar having engaging means spaced apart longitudinally thereof, and engaging 'means eX- tending from. said plunger to cooperate with the engaging .means of the bar, the engaging means of the bar being spaced apart longitudinally of thc bar such distance with respect to the reciprocation of the. plungerand the dimension of the engaging means of the plunger that said bar is reciprocated through its lesser. extent of reciprocation during and in the same direction as each reciprocation of the plunger, conta ct means carried by the respectiveends of the bar and electrically connected together, the mounting of said bar comprising means insulating it from the support-ing means of the solenoids, and contact means carried upon and insulated from ithe supporting means of the solenods and supplied to the respective solenoid to eect msuleted from each other, with which the said recprocaton of said plungerl respectlve Contact means om the bar make a1- ternate contacts upon the recprocatou of SCHOLFIELD the ber, this latter Contact mea-ns being C011- nected respectively to the conductor of the Witnesses:
