Definitions

  • 259/DIG 43 An a1r-dr1ven machine, such as a rotary v1brator, 1s [51] Int Cl B0" 11/00 mountable on a structure by cooperative male and fe- 58] Fie'ld DIG. 44 male parts and an air-inflatable envelope is interposed 259/DIG. 41, DIG. 42; 248/14, 15, 19, 20, 21, 22, 23, 25, 223, 224, 225; 415/121;
  • a vibrator such as those illustrated in the US. Pat. to E. F. Peterson, Nos. 2,917,290; 3,076,346 or as illustrated in the US. Pat. to C. G. Matson, No. 3,318,163, may be selected as representative of an air-driven machine mountable on and dismountable from a structure which, in the instance chosen here as an example, would be an object to be vibrated; e.g., a materialscontaining hopper, a conveyor, a concrete form, etc.
  • the typical mounting should be tempo rary; i.e., the vibrator should be removable when its assigned task is completed.
  • a common vibrator design will include some means by which it can be mounted on and dismounted from a structure, and experience has shown that the most efficient and least costly type of mount is that using cooperative male and female elements whereby the vibrator may be selectively moved into and out of engagement with the structure.
  • the male and female parts or elements are constructed so that a compartment, or its equivalent, is provided between them and in which the envelope means is disposed.
  • a still further feature is an envelope-to-machine connection that enables the envelope means to disconnect quickly and safely from the machine in the event that the machine is inadvertently started before being mounted-which would inflate the envelope simultaneously, whereby the envelope is simply blown off" via its connection to the machine and cannot cause damage, etc.
  • a further feature of the invention is to provide the envelope means as a plurality of separate envelopes so as to more uniformly distribute the pressure or forces between the machine and its mounting. Still further, the male and female elements are so constructed as to provide protective compartmentalization for the envelope means.
  • FIG. I is an elevation of one form of machine in its mounted status.
  • FIG. 2 is a partial section as seen generally along the line 22 of FIG. 1.
  • FIG. 3 is a fragmentary section as seen generally along the line 3-3 of FIG. 2.
  • FIG. 4 is a perspective of a portion of the mounting means, illustrating particularly one form of stop means.
  • FIG. 5 is a fragmentary view, partly in section, showing another form of mounting means.
  • FIG. 6 is a fragmentary view, partly in section, of another form of mounting, featuring a pair of separate envelopes.
  • FIG. 7 is an end view of the structure shown in FIG. 6.
  • FIG. 8 is a bottom plan view of the structure of FIGS. 6 and 7.
  • a vibrator is selected as exemplary of a machine to which the invention may be applied, and the ensuing description will proceed on that basis.
  • the vibrator shown here is of the type forming the subject matter of the above-mentioned Matson patent and is designated as a whole by the numeral 10. It comprises, for purposes to be served here, a housing 12 which forms an air-receivable: chamber 14 within which is eccentrically mounted a cylindrical rotor 16. A port 18 is receivable of air under pressure from any suitable source to drive the rotor in its orbit within the chamber 14. An air-discharge port will be seen at 20. The details, although not important here, may be learned from the Matson patent.
  • the structure on which the machine or vibrator is mountable is indicated at 22.
  • this may be any selectedobject to be vibrated.
  • the machine 10 and structure 22 have cooperative male and female elements 24 and 26 respectively, the latter preferably comprising a pair of spaced apart parallel tracks 28 welded or otherwise rigidly secured to the structure.
  • these tracks converge toward each other to afford a wedging action with complementarily sloped ramp portions 30 on the male element 24, and all these portions are so shaped that a recess or compartment 32 is formed between the parts of the structure and housing that face each other.
  • the face portion of the structure is its upper surface and that of the housing is its lower or base portion, but these will, of course, change geographically according to the position in which the machine is mounted. The description is therefore explanatory and not limiting.
  • the machine may be slid into and out of place on the structure, and it is desired that some stop means be provided along the line or path accord ing to which mounting is effected, especially when the structure is vertical and the machine is inserted from above.
  • One form of such stop means. is shown in FIG. 4 as comprising a ledge 34 against which the machine may be abutted.
  • FIG. 5 Another form of male and female elements is illustrated in FIG. 5, wherein a machine a is mounted on a structure 22a by associated portions 26a and 30a in which the wedging action described above is not used. As above, however, the compartmentation is provided, here at 32a.
  • an inflatable elastomer envelope or pancake 36 is used. In FIG. 5, this appears at 36a. Any suitable envelope may be used, having adequate strength, resistance to wear and abuse, etc.
  • the envelope 36 is inflatable crosswise of this path; i.e., it forces the machine and structure apart but in such direction as to augment or finalize the gripping action between the portions 26 and 30 (or 26a and 30a).
  • the envelope 36 is disposed in the compartment 32 (or 32a).
  • the housing 12 of the machine 10 in addition to having the main rotor chamber 14, is constructed in such fashion as to include an auxiliary chamber 38, here in its "bottom or the part that faces' the structure 22, and thus the housing has a wall 40 in which is formed an opening 42, preferably surrounded by a depending neck 44.
  • the wall 40 may be extended to include the male portions 30 and welding may be relied upon to construct the housing and its associated components.
  • the envelope 36 has an opening 46 which registers with the opening 42 via a telescopic fit with the neck 44, and the connection is improved by the use of an airtight seal 48.
  • Air under pressure from any suitable source is supplied to the auxiliary chamber 38 by means of an inlet 50 and, because of the air-conducting connection at 42-46 between the chamber and the envelope, the latter will be inflated.
  • the chamber 38 is connected by means of a second airconducting connection 52 (here external to the housing 12) to the rotor chamber port 18, so that the same pressurized air supplies both the rotor chamber and the envelope, which makes the system automatic.
  • the confinement of the envelope or pancake 36 in the compartment 32 gives it protection and places it where it functions most effectively.
  • the air-inlet means established by the chamber 38 and its connections 42-46 to the envelope and 52 to the rotor chamber 14 insures that both receiving areas are supplied at the same time, so that it is a simple matter to make the mechanical connection between the machine 10 and structure 22, after which the air supply is turned on and a proper augmentation of the connection between the machine and structure 22 is immediately and automatically effected.
  • the envelope will be automatically and safely disconnected by reason of the telescopic connection at 4446, so that the envelope cannot be overinflated etc.
  • the stop 34 prevents accidental dislodgement of the machine before and after the envelope is inflated.
  • a mounting member here a female element 55 is composed of an inverted channel 57 to opposite sides of which are welded angles 59 which form tracks like those at 26 and 26a.
  • the male element is a plate 61 which slidably fits between the tracks 59.
  • the mounted machine may be a vibrator of the type discussed above but its configuration differs because it is mounted on the male member 61 by an intervening mount 63 from which it is removable.
  • the vibrator comprises a casing 65 pivotally connected by a pin 67 to lugs or ears 69 formed integrally with a bottom portion 71 which includes a second pair of integral ears 73 to which a swing bolt 75 is pivoted by a cross pin 77.
  • the vibrator casing has a slotted lug 79 into which the bolt 75 is received, and a nut 81 is tightened to draw the casing tightly against the ears 73 by means of an abutment 83 on the casing.
  • the particular type of mounting forms no part of the present invention and other forms may be used, as may the mounting of FIGS. 1-4 to the extent that the situation accommodates the use of envelope means of the class already described.
  • the mounting portion 71 includes a bottom recess 85 spaced from but sealed to the plate 61 by welding or other means and the result is a cavity or auxiliary chamber that opens to the underside of the plate 61 by means of a plurality (here two) of openings 87, each leading to an envelope or pancake 89.
  • a plurality here two
  • openings 87 each leading to an envelope or pancake 89.
  • These are similar to but of course smaller than that described above but have the advantage that, in an elongated space, they cover more areas and thus are capable of more evenly distributing pressure or force as the envelopes are inflated to tighten the plate 61, together with the mount 63 and vibrator 65, to the structure 55; i.e., when the envelopes expand, they exert an upward force on the plate 61 and force its top against the overhanging lips of the tracks or angles 59.
  • each envelope S9 to the cavity or auxilary chamber 85 is telescopic, as shown at 91 and may be the same as that described above at 42-44-4- 6-48, giving the same safety results when envelope inflation inadvertently occurs without connection of the elements 55 and 61.
  • Air supply to the cavity 85 and to the interior of the casing 65 is here achieved by means of a modified T fitting 93 having an inlet line 95 for airunder pressure, an outlet in the form of a hose 97 for supplying the casing chamber and a connection at 99 to a drilled passage 101 that leads to the cavity 85.
  • the envelopes 89 are static, or not inflated, resulting in a loose fit between the structure 55 and the plate 61. Because the angles or tracks 59 enclose the structure from the sides (FIG. 7), the same compartmentation is provided as in FIGS. 14; i.e., the formation of a compartment in which the envelope means 89 is located, the angles 59 being in side-protective relation to the envelopes.
  • the plate carries at each end an arcuate depending skirt 103 (FIG. 8) which provides protection for the envelopes from the ends of the structure.
  • the envelopes are substantially completely enclosed.
  • FIGS. 6-8 the plural envelope structure of FIGS. 6-8 is not limited to the specific mount 63, nor to the specific form of vibrator 65.
  • the single envelope means of FIG. 1-4 could employ the mount, vibrator, etc., of FIGS. 6-8.
  • the fluid inlet means includes a housing portion forming an auxiliary chamber having a first fluid-conducting connection to the envelope means and a second fluid-conducting connection to the chamber.
  • stop means cooperates between the elements to limit said relative movement along said path in the direction of connection of said elements.
  • the female element includes a pair of spaced tracks defining a channel
  • the male element is shaped to fit the channel
  • the elements are fashioned to provide a compartment between them
  • the envelope means is positioned in said compartment.
  • the housing has a face portion disposed toward the structure when the vibrator is mounted and including a recess defined in part by the male element so that when the elements are fitted together a compartment is formed between the housing and the structure and the envelope means is disposed in said compartment.
  • the invention defined in claim 13 further characterized in that the envelope means includes at least a pair of separate side-by-side envelopes arranged for simultaneous inflation and deflation thereof.
  • one of the elements provides a pair of spaced apart tracks and the other element fits between the tracks, the envelopes are located between and protected at their sides by the tracks, and one of the elements includes a pair of skirts extending between the tracks in protective relation to the opposite ends of the envelopes.
  • oneelement has a face portion facing toward and spaced from the other element, said one element has an auxiliary fluid chamber and said face portion has a pair of openings therethrough and communieating with the auxiliary chamber, and the envelopes are located between the elements and communicate respectively with the chamber. via said openings.
  • each envelope is associated with its opening by a telescopicconnection so that in the event of attempted inflation of the envelopes when the elements are not connected the, envelopes will be forced off of their respective connections with said face por-' tion.
