1 Claims. "(or 259%1 y This invention relates to a vibratory mechanism and more specifically comprises certain improvementsover such structures as shown in my prior Patents No. 2,480,693 issued August 30, 1 949 ;'-l ]o. 2,518,250, issued August 8, i950; and No. 2,528,319, issued October 31, 1956; t r w I In general, the vibrators or vibratory mechanisms disclosed in the patents are provided with inlet and exhaust systems for fluid to actuate a rollingelement, and in each case the exhaust system is associated with the central bolt structure or fastening means that secures the cover to the housing of the vibrators. In each of the former constructions, additional securing lugs are required-which extend outwardly from the circular portion of the hous ings.

Each of the Patents No. 2,480,603 and 2,528,319 are solely confined to an exhaust system that comes out of the vibrator housing'through the bolt and about a predetermined cover structure and into the atmosphere. 'In the Patent'Noj 2,518,259, the same general exhaust system is employed, although this construction includes a bypass yent in the peripheral portion of the housing for the purpose of exhausting dirt or other foreign niattcr om with nt e hq in tse ft is o o he m i'n'g i qt of the Pres t nvent to provide an improved arrangement of fluid inlet and fluid outlet'meansfor operating a rolling element within its i 'of hearin at a ri rata y meq a ism- It is bet obi qt of th r se attent o o m us a housiiigtructfir r a Y IQratQrr mqha ism w erein the inlet and exhaust fluid conducting means are both positioned'at one point adjacent'the periphery of the housing of the vibratory mechanism. This eliminates any other form of venting or exhausting particularly through the central portion of the housing per se.

A-"furthen object of theprsent invention is to pro vide a securing rnean s that maybe centrally applied to a vibratory mechanism housing'to attach the entire structnre to a surface wall of a precast equipment forinducing vibratory action into such equipmentlbythe action of the vibrator.

Anbthe'r object of the present invention is to centralize the fluid inlet me'ans for acti ating the rolling element within a vibratory mechanism and the exhaust means from within theihousing so 'tliat the entire power actuating fluid structure only operates the device but also includes a self ueaang aqian"w ic is coincident with the exhaustsystern; p

A still further object of the present invention is to provide a tangential throat or opening 'connec t ed'wi th "a housing confininifa"'rdllingelement and"whcrein this throat structure 'may' b'e provided with a simple bore which is adapted to receive a screw machine part Other objects and advantages relating to the vibratory mechanism of the present invention shall hereinafter appear in the following detailed"de'scription liavirigfref-v ere'nce to the accompanying drawing forming" a part of this specification.

'In the drawing:

Fig; 3 is a fragmentary, end elevational view of the fluid inlet and exhaust portionof the vibratory'mechanis m to better illustrate the'relationshipbetween certainpafts of the fluid conducting 'syst em l" I The vibratory mechanismc'omprises in general a housing- 1 fo'rm-edas a-"'cup' shaped chamber having aperiphe'ral Wal1""2 with a closed side 3- and an open side '4 terminating in an a'n'nularcdge'S that is machinedfor coplanar abutting engagement' with a wall 6 er apiece of equipment substantially as best" shown in Fig. 2. "The housing or chamberl includes a raceWay 7 comprising annular rings-8- and 9 which fit within the bare-10 *of the-housingarid *include'tapered surfaces 11 and 1 2 to guide arolling element suchas a'ball 13-about the charn her in thehousingL-underthe'action of compressed air or other fluid that may be introduced into thehouisiiig aiwillbc presently'describedt" 1 A cover 14 i-sarranged=to"'snugly fit within the open side 4 of the housing 1 toabut the adjacent annular ring' '9 and in a position to hold bo'thof the rings 8'and '9 tightly against theclos'ed sidefi 'of the housing lf -The cover 1 is secured by means of-a sleeve15'to the closed'si'd'e 3 of the housing 1, the endsof the sleeve 15 being turned over-as at -16-and 17 to tightlyTand compactly "secure the/raceway parts and the cover within the cupped housing 1;. It should'be noted-that the turned over" end-"1'6 of the sleeve 15 provides a central 'supporfiwhichco operateswith the annular surface 5 of the cup opening to provide an additional stabilizing surface at'the central portion of the housing oftheVibrator'y mechanism for rigid abuttingcontact with the wall 6 or with 'anybther surface of this type. The opposite turned"i'r1-"end1 7 of the sleeve 1 5 forms a seat for-thehead18 of a'fastening bolt 19 that passesthrougha suitable opening'20 in the wall 6 to receive a -securing" nut 21 With'a shakeproof Washer 22 being interposed between the nut 21 and the Wall 6. Furthermore,- the-inturned-end17 of the sleeve 15' may also include a Washer or-indiciaplate structure such-as 23 to securethe latter against'the outer surface-of the closed side 3 of the housing 1.

Obviously, any form of through'boltor other fastening meansmay be 'used'for insertion through. thesle'evc 15 to securethe entire-vibratory mechanism structure to a piece of equipment that is to receive th'e'vibr'atory impulses from this device", such impulses beingcreated by the'hig h speed rotary action-of the rolling equipment'or ball i fifr which centrifugally induces-wsuch vibration. The central fastening arrangement of "the vi bratory mechanism is made" possible by the fluid-com ducting means incorporated into this vibratory mechanism This fluid conducting means comprises a throat 24 that is tangentially connected as an integral part of the housing IQ This bore is circular-as best illustrated in Fig. 3. A suitable fitting 2 7-comprising a screw machine" part that is preferably made'witha polygonal surface caa eur sueh-as sho n in Fig. 3 at' 2 8, is f'orced endwi se' the bore- 215. lhe ridges 29 of the fitting 3 27 are made to generally lie in a cylindrical area that is somewhat greater than the internal diameter of the bore so that the ridge corners 29 will cut into the gall surface of the bore 25 substantially as viewed in ig. 3.

With this arrangement of a cooperative fitting and throat bore structure, the fitting 27 is aligned axially within the bore 25 preferably to a depth so as to be flush with the outer terminal portion of the throat 24 as shown in Figs. 1 and 2, thus securing the fitting tightly within the bore, and in addition, the ridges 29 also counteract relative rotational movement between the fitting and the bore structure of the throat. This eliminates any particular type of orientation or other jigs or fixtures that might be needed for such purposes in view of the fact that the fitting can be driven into the bore in any particular angular relation therein to obtain the same cooperative results.

The fitting 27 is provided with an inlet aperture having a fluid discharge bore 30 that connects with an enlarged bore 31 that includes an internally threaded portion or section 32. A fluid inlet pipe or line 33 (see Fig. 1) has a threaded end 34 which. may be screwed into the threaded section 32 of the fitting to provide a fluid discharge supply system wherein fluid will be introduced generally according to the arrows 35 in Fig. 1 into the interior of the vibratory mechanism housing 1.

The inlet bore 30 of the fluid inlet system and fitting 27 terminates in a nozzle 36 that is easily located within the bore 25 of the throat 24. The external contour of the nozzle 36 includes an expanding, radially outwardly curved portion 37 which flares from the discharge end of the nozzle into the polygonal surface portion of the fitting 27.

The nozzle 36 and its external contour therefore provides a pocket in the bore 25 adjacent the ball carrying portion of the vibratory mechanism and the discharge end of the nozzle is located immediately adjacent the raceway while the polygonal portion of the fitting within the bore 25 is spaced outwardly from the nozzle axis and within the bore of the throat 24.

With the particular form of union between the fitting 27 and the throat 24 and as best shown in Fig. 3, a plu rality of longitudinal channels 38 are formed which are located radially outwardly with respect to the inlet bore 30 but with the channels in a circular group coaxially arranged about the nozzle and adjacent the wall portion of the bore 25. Thus, the exhaust system of the present device extends from the point 39 in Fig. 1 to the point 40 thereof whereby excessive and spent fluid is discharged from the vibratory mechanism through bore 25 and substantially as indicated by the arrows 41 in Fig. l.

The nozzle 36 is aligned substantially on the median plane of the housing 1 and is tangentially directed into and partially through cooperative slots 42 and 43 which are formed in the adjacent annular rings 8 and 9 of the raceway 7 respectively. These slots together form the opening through which the impelling air or fluid under pressure may enter the housing to rotate the ball 13 at high speed. The same cooperative slots 42 and 43 also form an opening through which the exhaust air passes into the exhaust chamber portion of the bore 25 encircling the nozzle structure and from which the exhaust air is coaxially returned out of the channels 38 into the atmosphere adjacent the pipe line 33 which initially supplies the fluid under pressure to the device.

During the operation of the device, the actuating fluid is directed about the sleeve 15 which now forms a central core that will eliminate some of the turbulence within the device to promote a better circulatory action of the air and ball. This action, together with the tapered annular portions 11 and 12 of the rings 8 and 9 which provide an annular clearance area 44, forms a means for removing dirt andforeign matter from within the raceway 7 which will move about this internal portion of the device to be directly discharged through the slot openings 42 and 43 and out of the exhaust channels 38 between the fitting and the bore 25 of the throat 24. This coaxial unitary arrangement of the air system, together with the cleaning feature thereof and the sleeve 15 fastening means incorporated centrally of the device and as shown in the drawings, provides a simple and eflicient arrangement of vibratory mechanism that is easily manufactured and readily applied to substantially any kind of a surface or wall of a piece of equipment that is to be subjected to vibratory action. Furthermore, the fitting 27 of the device may be withdrawn and replaced with a diflerent fitting if that is desirable or necessary.

Certain changes and modifications in the exact combination and construction of the elements shown and described are contemplated within the concept of the present invention. All such deviations and modifications shall, however, be governed by the appended claims directed to the present invention.
