To allwhom it may concern:
Be it known that I, LEONARD D. Monius, a citizen of the United-States, residin at Chicago, in the countyof Cook and tate I of Illinois, have invented certain new and useful Improvements in Chime Striking Actions, o which the following is a specication. v
This invention relates to actions for striking and causing the resonant vibration of resonant objects, such as chimes, bells, and the like, and while the invention is capable of embodiment in various forms, I`
ur oses of illustration in the present application, an action adapted to operate upon a chime.
One of the primary purposes of this invention is to produce an action which will be reliable and eifective in operation so as to deliver a sharp impact to the chime, which will cause it to resound loudly and clearly.
` Another object ofLthe invention is to provide novel and simple means for damping the vibrations of the chime to thereby control theresona'nce and the sounds reduced so that the tones will not be un uly prolongied or continued to an extent-which will pro uce aninharmoniou's eiect in conjunction with -tonesproduced by subsequently actuated chimes.
Another object of the f inventionl Ais to produce an action which will bepositive and lses lnection with the accompanying reliable in operation, one which will y.besimple in construction and not'liable to get out of order, and which can -be cheaply.v
manufacturedl and readily installed.
Other objects and many oftheinherent advantages of this invention .should be readily a preciated as ythe same becomes better un ers b reference to the following description w en considered incon-4 drawings. Referring to the drawings; i Fig, 1 is a front view- .o an.. tuitionl em.
Abolying myL invention;
ig. 2 is a side view thereof, withathe 1 arts in normal ition- 4and P rig. a is viswghewing am y tion of the partsfjust prior to engagementv ofthechimebythe r.. '0
Referring now to the drawings more in detail,` reference characterv 5 indicates a lmember ,of the-'frame upon which the'chimes and striking actions are `mounted. It will be understood that-a seriesofchimes are all' im. semi ir. 4mm.
mounted, on the same frame, and that since they are all alike, one only is shown in the present instance for purposes of illustration.-
rIfhe chime 6 is suspended by a cord 7 encirchng a plurality of buttons 8, 9, 11 and ,12 carried by a plate 13 which is attached by screwsv 14 .or'otlierwise to. the front of the frame member 5. While a Itubular chime is illustrated in the present instance, it is to be understood that other resonant objects adapted for vibration by \a hammer may be substituted therefor within the scolpe of my invention.-
lpon the forward face of the frame member 5 above the chime,there is mounted a transversel extending block or board 15,
upon 'the orward faceof which there is mounted a bracket 16 projecting forwardly from the member 15 and comprisi spaced members 17 and 18, the ldistance tween which may be regu screw. 19, the lower member 18 having fu crumed thereon at 21 a yoke 22 carrying an armature 23'at its upper end and shaped to -provide a shank 20 at its lower end, which carriesv the hammer 24 anddamper 25, as will be later ex lained. l.
` vU on the mem r 17 of the bracket, there is. xedly mounted an electromagnet v26, the upper pole or poles v27 of which are 'disposed in` roximity to the armature 23 .carried by t e yoke vThe armature and yoke mounting is described in-detail in my prior Patent v#1,282,276 issued October 22, 1918.
The hammer 24 is suspended from the yoke by a resilient shank 28 and the damper 25 is also suspended from the yoke by an angle-shaped `shank 29 which4 may also be resilient in character. The damper 25 comvprises a body of appreciable weight, preferlated by an adjustin vably made of' meta and faced on its'lowerin spaced relation with res and the amature `23 'tioned laterally of the magnetic pole The arts'k may be telthis positionsole y gravity since the'hammer made b. ofvwoodis lsurface `by a'cushion or damping disc 31 I .which is adapted to en ge the upper end of `.the chime and damp t evibrations thereof. 4
1N wherein the 4damper is shown in ent with the chime, the hammer t to the chime lio f bracket member I8 and projecting upwardly into engagement with the armature 23, which spring tends to restore the parts to the normal position shown in Fig. 1. To
steady the action and decrease the rebound as well as to afford an abutmentfor the yoke 22, I prefer to mount in the path of the armature 23 a cushion block 33 having a cushion face 34, the block being capable of adjustment through the instrumentality of an adjusting screw 35.
In the operation of my invention, upon energization of the electroma et 26, the p ole or poles l27 will attract t e armature 23, causing the yoke carrying the hammer and the damper to swing from the full line position shown in Fig. 2 to thedotted line position shown in Fig. 3, thereby causing the hammer 24 to impact the chime 6. It will be observed that when the armature 23 is directly in alignment with the m etic poles, theparts will be in the full line posi'- tion shown in Fig.l 3, but the momentum of the parts in swinging from the inclined position shown in Fig. 2 carries them past this vertical position and causes a sharp blow to be struck by the hammer against the chime and an immediate withdrawal of the hammer to the full line position shown in Fig. 3 so that it will not interfere with the vibrations of the chime. As soon as the electromagnet is de-energized,fthe parts will return by gravity to the position shown in Fig. 2, thereby engagin the damper with the upper end of the c `me to damp. the vibrations, and this return movement is in the present instance expedited by the light spring 32.
It will be apparent from the foregoing that I have provided an action which is simple in construction, positive and accurate in operation, one which is not liable to get out of order, and which can be economica 1y manufactured and quickly installed, and"- while I have shown and described a preferred embodiment of the invention, the details of construction are capable of considerable modification and variation without/departing from the spirit of the invention' as defined in the followingclaimsz' l. Ina chime striking action, the combination of a vertically disposed cylindrical chime, a bracket projecting laterally abov v said chime, a yoke pivotally mounted between its ends upon s aid bracket at one side of a vertical plane intersecting saidchime,

2. In a chime striking action, the combination ofI a cylindrical chime, a pivotally mounted yoke, a hammer suspended from the lower end of the yoke, an angle arm fixed to the lower portion of said yoke, a damper heavier than said hammer carried by the free end of said angle arm in position to overbalance said hammer, and electrically actuated means disposed above the yoke pivot for swin ing said oke on its pivot against the action of sai damper to 1mpact the hammer against said chime.
3. In a chime striking action, the combination ofa vertically disposed cylindrical chime, a yoke sus ended between its ends on a horizontally isposed pivot, a hammer carried by the lower portion of said yoke, an vangle arm fixed to the lower portionof said oke, a 'damper carried by said angleA arm -aterally of a vertical plane intersecting said pivot and overbalancing said hammer to normally engage with the upper end of said chimepa cushion block for't e upper portion of said yoke, a spring normally urgmg the upper portion of the yoke towary s said cushion-block, and means for swinging pivot against the force :of saidisprin 4.-..Ina chime `striki action, the combination of a verticallynisposed cylindrical chime, a yoke ivoted between its ends above and atgone side of said chime, an armature carried uponrtheupper endv of said yoke, a hammer suspended from Sa'id yoke', a damper also suspended from said yoke but projecting laterally therefrom over the upper endof said chime, the weight and leverage of saidA damper beingadapted to overbalance the hammer and normally engage the damper with the chime and retract the hammer therefrom, and electromagnetic means acting upon said armature for swi ng the yoke to retract the damper fromY an impact the hammer against said chime. .A
