ie it known that l, iV-nimmt S' inns, a citizen ot the United States. and resident ot Jackson. in the county of Jackson. in the State ot' I\'iichijan,`have invented new and useful improvements .in Signals, of which. the 'l" llo\\'ing`, taken in connection with the uccoi'npanving '.lrawings, is a full, clear7 and exact de: iption.

This invention relates to certain i1nprorements in signals and more particularly to electrically operated signals of the mechanically actuated diaph agni type susceptible et various uses. but particularly applicable to autoinobiles7 niotor boats and other moving Vehicles.

The primary object of the invention is to produce an Y electrically operatedv signal adapted to gire ce instai'itaneous alarm7 of vsimple construction and which can he manuvgcetured at a considerably reduced cost oror electrically operated signals of the. inotor driven type.

A further object is to construct an electrically operated signal ot this type which shall he capable ot producing avcoi'itinuous note or sound.

Other objects and advantages \\iil appear troni the following description taken in con? nection Ywith the acconipanyingv drawings, in which-- Figure l .is a side elevation of a signal niade in accordance "with this invention Fig'. 2 is a vertical central section with tresonator 'partially broken away.

It will be apparent that when the solenoid 5 is energized Atrom any suitable source ol electric power, the plunger -l- .vill be drawn upwardly along the shaft -l0--. The seat 'formed in the inexnber -16- and closed by the cover 174- is sulticieiitly 1g deep to allow the nut -llto lie in a position at which the teeth will not engage the projections -lS-- upon the cover. l

ln other words,` the seat within the plunger is of sutlicient depth or size to allow the 1 5 nut nith the ratchet 'teeth thereon to move out of engagement with the projections upon the plunger so that the nut may 'freely rotate with respect to the plungerv TWhen the plunger is moved upwardly by the energized solenoid, the inertia of the shaft iand gravityT cause the nut Mldto lie in Contact with the cover *17- and the teeth -tltherefore engage the projections #-lSM upon the cover, thereby preventing rotatioi'i ofthe nut with v(respect to the portions 16- and -liof the plunger while the plunger is beingr moved in an upward direction.

When the electric current isbrolren, the 3g plunger tends to tall by gravity into the portion 27 and the inertia of the shaft Ml O holds the nut -lel in Contact with 'the member -1G-, thereby withdrawing the teeth -19- ;trom engagement with the projections 1S-, whereby the nut -lllis allowed to 'freely rotate within the member -ltand the plunger is returned to starting position after each operation without rotation ot' the shaft -10-- or the actuator 0 --29-.

In Figs. 7 and 8, is shown a slightly varied and for many purposes preferred form of' the' invention by means of which a vcontinuous rotation of the actuating member -29- may be produced As shown, the shaft v-1O-- is provided with two oppo sitely inclined spiral grooves -3;- and 1 --33-.

The plunger comprises an upper and a 5o lower case member -3eand *4555-7 respectively, secured together by screws -36-- @ne of these portions, as the portion --355 is' provided with suitable ratchet teeth 7 upon its internal circumference and the inclosed actuating member 3S- is provided with a pair of dogs 39- sprinon pressed into engagement with the teeth 37- to prevent rotation of the member -38-- in one direction within the plunger -3-1l-.

The member 38 'tongue --l0-- operat 62 and --33-7 sively The actuating :mecha-mein for the vrotary actuator mienne in this .comprises a double solenoid, such solenoids adapted to he alterrections for alternately bringing the contact points --l-alwand m15*- into circuit closin" relation with suitable terminals Alland -l7-, respectively, for alternately closing the circuit leading to the respective solenoids so arranged that when the plunger is at the limit of its movement in a downward direction, the circuit leading to the solenoid will be energized to return the plunger upwardly and when the plunger reaches its limit of movement in an upward direction7 it will contact with the flange -43-, raise the Contact point 45- into circuitclosiug relation with the terminal -47 and break the circuit through the contact #illand the terminal H46, whereby the solenoid llwill be energized to ret-urn the plunger downwardly.

The operation or' the actuator 3S- Within the plunger will be readily apparent. The plunger starting from the limit of its movement in a doivmvard direction moves upwardly through the spiral groove 32- and as the actuator -wl$- is held against rotation in a direction from lett to right, the

shaft is thereby rotated in a direction from right to left.

Then the plunger reaches the limit of its upward movement traveling in the spiral groove -l2-, the shaft m10- continues to rotate in the direction from right to left, whereby the spiral groove 33m is carried toward the tongue -40- upon the actuator n38- and if the reverse movement is not applied imn'iediately bythe energizing of the solenoid -4l9, the shaft carries the actuator -38- in its rotation from right to left, the projection --el0 being positioned at all times in the reverse groove -33 and when the plunger is drawn downwardly by the solenoid -Jl8--, the tongue --40- necessarily moves in the groove --33-, whereby a continuous rotation in the same direction of the shaft lO-- is produced, resultingr in a continuous movement of the 29- in the same direction so long as electrical current supplied to the coils'.

This Same action takes place when the plunger starts in its upward movement the t' 'ne e., rotation ol the shait --l 0- to cause the tongi'le W40- to move into engagement xwith the proper groove for ausinga continuous rotation of 'aid shat't in the same direction.

The electrical connections necessary to a source ot' electrical power for energizing the solenoids may be ot any well known and usual form not necessary to herein illustrate and desc'ibe, land suitable insulation in the forming of the solenoids and in the sepa ation of the parts are herein shown, and further description is unnecessary.

.ln Fig. 9, I have shown a modified iorm ot a one-way actuated signal in which `the spiral shaft is the movable meinber and the toothed wheel is rotated by the clutch mech* anism which is stati nary therewith when the shaft is moved in one direction. In this structure the plunger 50- is rigidly mounted upon the end oi' the spiral shaft *M and is movable in the core --QQM- along guideways --:2 and H23- in the. same manner 1s the plunger -l5- shown in Fig. 2.
