' The present invention, 'while rela'ting particularly-as indicated'to'chimestresonated bells? such are adapted for household 11se,"*re1ates in a broader sense to signal -'or 'sound produc'ing devices irrespective of the use to which they are put.

I am aware of the 'fact that signal-devices have been heretofore deve'lcpedinwhich the striker and vibratory element thereofeare confined with- "in *a housingsympathetically tuned *with the vibratory-element. fieweverf in these priorart'devices-the particular mo'imting fer such elements is adaptedonly for usein conjunction witha particular resonance housing --=0r housings that is, 'for examplefifer eithera so-calied single or dual or universal purp0sedeViCe and, therefore,- entirely different mountings a-re required for each difierent type of'device.

in'such prior-art devices, the resonance chambers "associated withvibratoryelements of different pitches havebeen of difierent lengths whereby thefcrmation or composite-units of the dual or "universalpurposetype-hashot been feasible.

Accordingly, it isone principal object or this invent on to provide a signaldeviee "which; in afidition to being *capable'of reinforcing or intensifying the sound produced by a" vibratory element, is= of such-"construction "that the principal elements 'thereo'f, viz., the vibratory and striker elements on-an interchangeable carrier can-be inserted-into any 0f severaliorms of resonance housings. 3

Referring n0w tothe-drawing and firststo mgs.

d of ousi I, I have found that by varying the size thereof, it is possible to sympathetically tune the resonance chamber formed by housing I with vibrator element 2 without varying the length of said housing. Whatever the scientific foundation for such tuning may be, it has been determined that an increase in the pitch of the vibratory element necessitates an increase in the size of opening 5 in order to effect reinforcement or intensification of the sound emanating from the vibratory element.

The vibratory element 2 and the striker lement 3 are each mounted on a single carrier 6 which is slidably fitted into housing I and retained therein simply by the friction between said carrier and the inside wall of the housing. Said carried 6 comprises a channel-like body portion formed with parallel flanges 1 and a bottom con necting portion 8 shaped transversely so as to fit into one of the corners of housing I, as shown in Fig. 3. At each end of said carrier 6 and adjacent the edges of the flanges I, there are a plurality of slots 9 which define lugs over which the inwardly extending tension springs Ill may be hooked. The inner end of each spring Ill is formed with a hook engageabl in one of the two apertures l I in vibratory element 2 whereby said vibratory element may be resiliently supported between flanges 1 out of engagement with the carrier proper. Several slots 9 are provided so that any of several different vibratory elements may be mounted thereon with springs 10 being located preferably at or near the nodal points of the vibratory element. The bottom connecting 14 in register with such openings and then letting the flanges I spring together.

Mounted on web I2 is a solenoid l5, surrounding which is a casing [-6 having lugs l1 projected through apertures in web l2 and bent over to retain the solenoid in place relative to web I 2. Casing I6 is s otted as at l8 so that the solenoid leads. not shown, may project through such slot for convenient connection to a suitable source of electric current. Wihin solenoid l5 and formed as a part of casing is is a tube [9 preferably of brass or like material. The striker element 3 consists at least in part of iron or like magnetizable material and is reciprocable in said tube [9. Striker 3 is yieldably held in its retracted position, as shown in solid lines in Fig. 1, by means of a tension spring 2|] having its opposite ends respectively connected to an end cap 2| on tube l9 and to striker 3. A cushioning washer 22 is pref erably disposed in cap 2i to prevent objectionable banging of striker 3 against said cap. That end Fi l of striker 3 which is adapted to strike vibratory element 2 is preferably of brass or like material, although it is contemplated that materials such as leather, felt or the like may be employed. The solenoid l5 and striker 3 are so spaced relative to vibratory element 2 that the efiect of the magnetic field alone urges the striker-to a position with its vibratory element striking and just short of engaging the vibratory element. However, it can now be seen that energization of solenoid I5 will urge striker 3 to the left as viewed in Fig. 1 to the position shown in dotted lines to cause the end thereof to strike the vibrator element and immediately bounce away therefrom and then, upon deenergization of solenoid l5, the tension spring 20 will return the striker to its retracted position. That is to say that the inertia of thestriker will carry the same far enough to the left to strike the vibratory element and at the same time the combination of the magnetic field, the spring 20 and the striking impact causes the striker to immediately retract away from the vibratory element even though the solenoid remains energized. This produces maximum amplitude of vibration of the vibratory element and results in a clear strong note which is further amplified by the sympathetically tuned resonance chamber formed by housing I.

Insofar as the device illustrated in Figs. 4 and 5 is the same as that of Figs. 1, 2 and 3, like reference numerals have been used to designate like parts. The device illustrated in Figs. 4 and 5 is a dual purpose unit and, as shown, comprises two longitudinally

contiguous resonance housings

25 and 26 forming a partition wall 21 therein:- tween.

Housings

25 and 26 are of equal length and each is formed with a. closed upper end and a longitudinally extending opening 28 and 29, respectively, in its side wall. The length and location of such side wall opening is such as to sympathetically tune each housing with the vibratory element therein. I have found that the length of such side wall opening must be increased as the pitch of the vibratory element therein is increased. It is to be understood that instead of

openings

28 and 29 being provided in the side wall of the housings, openings at the top and bottom ends may be substituted, as in the case of the unit illustrated in Figs. 1, 2 and 3.

The carrier assembly with vibratory element 2 and striker element 3 mounted thereon is the same as that illustrated in Figs. 1, 2 and 3 except that striker 3 is provided with an end 30 projected through an opening in cap 2| and through registering openings I3 and 3| in carrier 6 and partition wall 21, respectively, to a point short of engaging vibratory element 2 in housing 26. Vibratory element 2 in housing 26 is resiliently mounted on carrier 6 in a manner similar to that in hous ing 25 but because a separate striker is not required, the web plate l2 has been omitted. In this case the opening [3 in carrier 6 is in register with opening 29 in housing 26. The normal posi--, tion of projecting end 30 of the striker is as shown in Fig. 4, but such end is movable by inertia to ward the right therefrom to sharply strike the vibratory element 2 in housing 26 by interposing a compression spring 32 between cushioning washer 22 and the bottom wall of cap 2|.

It can now be seen that upon energization of solenoid l5 encased within casing IS, the striker element will move toward the left, as viewed in Fig. .4, in opposition to the tension spring 20 to strike vibratory element 2 in housing 25 in the same manner as previously described in relation "itoFlg. 1. when,amen iieenergizatien crsclenoid 15, the tension spring 20 will causefsaid striker eiement to moveteward "the right, whereupon "theinertia thereo will compres's'springl'fl so that the projecting *end 30 *of thestrikeriwilisharr t' :strikeifinhe vibratory .iele'mentsc in housing "26 and immediately upon 'sozstrik ing Fthe bratory Pelerment, the :"comptession sprin'g c'g ether with impactof the strikinggwfll 'caus'ezasain end- 311 ito :be 'force'd "thank: 410 the normal position shcw-n ii igpe. rrnus it can be:seen thatisuceessivereneirgization and deenergizationrofsolerioid 515 die iectsa two note' bing bongssignal.

The -*so-called universal purpose signal device iillustrated 'in -FigsKS, 7 and 8 *is substaritial'lqy the, same as -the dual --purpose device illustrated in Ei-gs. -34 an'd fi. Elie-only d-ifierent 'featureadf tliis universal purpose device is that the webplaite fl m carrier ii hasmounted *thereentwo striker eleunents: am d two solenoids wheseby successiveenergization and deenergization of onesolenoid effects a two-note signal, as in the case of the dual purpose unit illustrated in Figs. 4 and 5 and energization of the other solenoid efiects a single note signal. Thus, the solenoids may be wired to push buttons disposed, for example, at the front and rear doors, respectively, of a home and because of the difierence in the signals, the tenant or owner can readily ascertain which push button was actuated.

While in the accompanying drawings the resonance housings are shown as being of sheet metal, it is to be understood that the same may be made from extruded tubing or, if desired, be fabricated of wood or like material in order to vary the tonal quality of the signal. However, regardless of the materials used in making the housings, it can be seen that once the sizes and lengths thereof are standardized, a single universal carrier 6, on which both the vibratory element 2 and the striker element or elements 3 are capable of being mounted, can be used in a wide variety of combinations, as for example the three variations illustrated, whereby a suitable web plate with the proper striker and solenoid assembly thereon can be readily mounted thereon and simply slipped into the housing. Likewise, as shown in Figs. 4 and 6, the web plate may be omitted altogether and only a vibratory element 2 mounted onto the carrier 6. To summarize, it can be seen that there is but one standard carrier 6 and two different web plates, one of which has a single or double-ended striker element thereon and the other of which has both a single-ended and a double-ended striker element thereon, all of the other parts such as the tension springs l0, solenoids l5, casings l6, etc. being identical.
