SPECIFICATION forming part of Letters Patent No. 455,660, dated July 7, 1891 Application tiled December 16, 1889. Serial No. 333,797. (No model.) n

To a/ZZ whom, it may concern:

Be it known that I, HENRY COOPER, a subject of the Queen of Great Britain, and a resident of the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Agitating and Circulating Air in Rooms and other Apartments, of which the following' is a specification.

My invention relates to that class of machines through which the agitation and circulation of' the air are effected by means of blades or fans which are appropriately operated to accomplish the desired results through the instrumentality/ot a suitable motor, and has for its object the production of a mechanism of this class which shall not only be simple in construction, but more cflicient in operation and less liable to get out of order than those heretofore in use.

To these ends myinvention consists, first, in aseries of fans and in the means whereby they are each caused to rotate around its own axis; second, in a series of fans and in the means whereby they are not only caused to rotate around their own axis, but with the others to revolve around a common axis; third, in the peculiarities of the means made use of for imparting the desired movements to said fans, and, fourth, in various other constructions, combinations, and arrangements of parts subsidiary thereto, all as will hereinafter more fully appear.

Referring to the accompanying drawings, which form a part of this specification, Figure lis a sectional elevation of a machine embodying my invention, the section being taken in a plane passing through the main axis thereof, which is shown in elevation; Figs. 2, 3, 5, G, 47, 8, 9, and 10, elevations, re` spectively, of modifications of such mechanism, in all of which figures, with the exception of Fig. 5, parts are broken away or shown in sections for greater clearness of illustration; Fig. 4, a plan of the mechanism shown in Fig. 3; Fig. l1, a sectional detail showing a spider in which the arms supporting the fans are journaled, as well as a brake whereby to regulate the velocity with which such fans or wheels rotate; Fig. l2, a sectional detail showing devices by means of which the machine may be suspended from the ceiling' or other convenient support and its altitude regulated; Fig. 13, a transverse section of the part shown in Fig. l2, taken in the line :c :c of said ligure; and Fig. 14, a detail showing a portion of one form of mechanism by means of which the motor-spring, when one is employed, may be wound up.

In all the figures like letters are employed to designate corresponding parts.

A indicates the housing, in and upon which the various parts of the machine are or may be mounted, the same consisting of a suitably-fashioned base-plate a, to the upper side of which is secured by means of screws d an inverted-cup-shaped top or cover a? and forniing with it a box-like structure, for a purpose to be presently explained.

Fixedly secured to the base-plate c near the center thereof is a rod or stud B, which extends upward through the top or cover a2 and receives above the same the spider C in suitable slots c, formed in the wings of which are secured the inner ends of the arm D, that support at their outer extremities the fans E E E2, through the instrumentality of which thc agitation and circulation'of the air are directly effected. These fans, in the preferred form of construction, consist of a plurality of blades or wings c, the cylindrical stems c of which are adjustably secured by means of screws e2 in correspondinglyshaped sockets e3, formed radially in a body or hub-like portion e4, whereby to permit of the adjustment of such blades to bring their faces into different angles with respect to the plane of rotation of the fans, as may be desired. As thus constructed, these fans are secured to the ends of shafts which'are mounted in suitable bearings d, formed in lugs d', projecting from the outer ends of the arms D. I propose in practice to employ aseries of these fans in each machine, three being shown in the present instance, of which the fan E is secured to the outer end of the horizontal shaft e5 and the remaining fans E E2 to the upper and lower ends, respectively, of the vertical shaft c,

Located below the arm D is a wheel F, through the instrumentality of which and the and e8, with which it is in gear, the


rotation of the fans is effected, the'wheels It:

es being fast upon the shafts e5 and e6, respecti ively. This wheel F is made of the proper diameter to carry its rim outward from the axis of the rod or stud B to near the outer extremity of the arms D, and engages with the wheels e7 es, either by means of teeth, by friction, or by a band or cord, the proper relation of the arms D with respect to the wheel F being at all times insured by rolls b4, which, journaled in suitable hangers depending from the under side of the former, rest against and roll upon the upper surfaces of the latter. In Figs. l, 5, and 8 this engagement is illustrated as accomplished by means of teeth, the wheel F being provided with teeth b b upon its upper side and periphery, which engage with appropriately-shaped teeth formed in the periphery of the wheels e7 e8. In Figs. 2, 6, and 9 this engagement is shown as effected by friction, the wheel F in this example being provided in its upper side and in its periphery with appropriately-shaped grooves f f', in which the correspondinglyshaped peripheries of the wheels el e8 are respectivelyu held by suitable pressure, the grooves and peripheries in such cases either being left smooth or serrated, as may be desired, while in Figs. 3, 4, 7 and 10 the engagement between-such parts is shown as effected through the instrumentality of a cord, which, passing around the peripheryof the wheel F the proper number of times, also embraces the wheels e7 e8, suitably-arranged idlers b3, mounted in a bracket 514, secured to the arm D, being employed for properly guiding the cord to and from the wheel es. As thus constructed and arranged,the rotation of the fans, as will be seen, may be effected either by, rst, revolving the arms D, and with them the fansE E E2, around the rod or stud B while the wheel F is held stationary; second, by rotating the wheel F upon its axis while the arms D are held stationary, and, third, by revolving the arms D and rotating the wheelF at the same time, but in opposite directions.

In Figs. 5, 6, and 7 is shown an arrangement of parts whereby the arms D and fans Aare revolved while the wheel F is held stationary, the spider C in this example being fixedly secured to a sleeve H, which is fitted to rotate upon the fixed rod or stud B, and the wheelF is rigidly secured to the housing A. In Figs. 8, 9, and 10 is illustrated an arrangement in which the wheel is rotated and the arms D are held stationary, the wheel F in this arrangement being fixedly secured to `a sleeve I, which is fitted to rotate upon the rod'or stud B as an axis, and the spider C is rigidly secured to said rod or stud, ywhile in Figs. l, 2, and .3 is shown a still further arrangement in which both the arms D are revolved and the wheel F rotated, the spider supportingahe former being secured to the l upper end of the sleeve H and the wheel F being similarly secured to the upper end of thet sleeve I. rPhe arms D, through the spider t, being thus secured to the sleeve H,

or the wheel F being secured to the sleeve l, or both the wheel and arms being secured to said sleeves, respectively, it follows that when one or the other or both of these sleeves is or are rotated the arms D, the wheel F, or both said arms and wheel, will be carried around with it or'them and the rotation of the fans thereby attained. To effect the rotation of these sleeves,'various means may be employed-such, for instance, as aband or bands from any convenient source of power. (Not shown.) I prefer, however, to make use of aspring-motorfor this purpose, and for the sake of convenience and compactness to locate v the same in the box-like housing A.

In the construction of. this motor I preferably employ a volute spring h, which, sur rounding a sleeve t', loosely mounted upon the rod or stud B, has its inner end ixedly secured to said sleeve and its outer end firmly attached to the plate 7L', which in turn is secured by screws h2 to lugs or stands h3, projecting upward from the base-plate Ct. From the sleeve t' rotary motion is communicated to the sleeve H through the instrumentality of a train of wheels k, l, m, n, 0, and p, the gear la being mounted upon the rod Vor studB and connected to the sleeve 11 through the intermediaries of a ratchet h4 and pawls k.

whereby to provide for the winding up of the spring, when required, without rotating such gear and through it the train of wheels intermediate the same and the sleeve- H. The wheels l on. and n o, on the other hand, are lixedly secured to shafts q s, respectively, which are journaled in the frame t, secured by screws t to suitable lugs or studs t2, also projecting upward from the base-plate d, while the wheel p is iixedly secured to or formed in one piece with thesleeve H.

With a motor as thus described provision is made for the rotation of but a single sleeve, as H. Vhen, however, a second sleeve I is made use of, as is the case when both the arms D and wheel F are rotated, additional wheels a and c become necessary, the former of which is secured to the lower end of such sleeve, while the latter is supported upon a suitable stud c', depending from the frame t, as shown, and meshing with the wheels o and u serves to communicate a rotaryvmotion to said sleeve in a direction opposite to that imparted to the sleeve H. the employment of a single sleeve I-I will be sufficient, as a duplex sun-and-planet motion In most instancesdown through the plate hand is provided at its lower end with a gear t", .which meshes with a gear ft2, secured to the shaft that is journalcd'in the plates ce h; This shaft, in the preferred form ot' construction, is provided with a polygonally-shaped socket l1"", extending axially through the same for reception of a suitable key, by means of which it may be rotated. n

In Fig. Il I have shown a means whereby the velocity of the fans may be regulated, and in Fig. l a device whereby theirrotation may be wholly arrested, the former consisting of a suitable brake y, which may be applied to either the spider C or hub of the wheel F, as desired, and held in contact with the rod or stud B by yielding pressure through the intervention of a screw y', tted to a socket y2, and acting through the intermediary of a spring ys, and the latter consisting of a barY or rod z, fitted to slide in a loop z in such a manner as to be raised above the line of movement ot the wheel F and arm D or depressed below the same, as indicated, respectively, by dotted and full lines in Fig. l, the bar being held in adjusted position by means of a spring z2.

As thus constructed, the machine may be either suspended from above or supported from below, as preferred, and for this purpose I provide the rod or stud B with a ring at its upper end, and the base-plate a with a depending shank a4, with' the former of which may be employed a hook secured to the ceiling or other convenient support, and with the latter a stand L, having formed in its upper end a socket a5, in which the shank c* may be received and held by the spring lockingbolt a6, engaging with a groove a7, formed therein.

The hook which I prefer to employ when suspending the machine'from the ceiling or from above is best shown in Figs. l2 and 13, and consists of the body portion d4 and the hook or stem portion The body portion (Z4 is provided with a ring d6 at its upper end for engagement with a suitable support, and also with an axial orifice di, the same being formed of the proper' shape in cross-section to permit of the portion Z5 sliding longitudinally therein. From the orifice (Z7 in the walls thereof, at different elevation, is formed circumferentially a series of grooves d8, into which the hook (Z9 on the upper end of the portion may be turned and there held,its d isconnection therefrom being eit'ected by rotating it slightly in the opposite direction and sliding it either up or down, as desired. To the lower end of the portion d5 is formed a hook dw, with which the ring on the upper end ot' the rod or stud B may engage, and in order to prevent the withdrawal of the p0rtion (Z5 from the orifice di the portion d* is provided with a suitable cap du, screwed to its lower end and having an orifice through its center of a size and shape to loosely fit the'body ot the portion (l5, so that while permitting' of such portion being rotated and slid therein the hook or projection on its uprbe removed from the machine per. end willbe incapable of passing therethrough.

The hook above described, however, while showing a convenient form of device for suspending the machine from above, constitutes no part of my present invention, but may be dispensed with, if desired, and any other form of hook employed in lieu thereof.

In Figs. 8 and 14 I have illustrated an appliance by which the winding up of the spring 7L may be effected. In the construction of this device I make use of a polygonally-shaped shaft m', which is adapted to tit the socket i4, formed in the shaft 113, and slide freely through a correspondingly-shaped orifice formed in a bevel-gear m2, mounted in a suitable frame m3, which in turn is adapted to engage with and be supported by lugs m4, projecting from the stand L. lWIeshing with the gear m2 is a second bevel-gear mwhich is secured to the end ot' the shaftm, also mounted in the frame m3, and provided at its outer end with a winch 'm7 or other convenient means,whereby its rotation may be attained. By thus mounting the several parts on the frame m3 I provide a convenient means for winding up the spring, which, while efficient tor that purpose, may

when not required.

From the foregoingv it will be seen that I produce a machine for agitating and circulating air in rooms and apartments which is not only simple in construction and automatic in its action, but admirably adapted to the purpose for which it is intended.

While in the preceding I have described the best means contemplated by me for carrying my invention into practice, I wish it distinctly understood that I do not limit my- Y self strictly thereto, as it is obvious that I may modify the same in various ways without departing from the spirit thereofas,.for instance, instead of employing a single spring for operating the motor I may employ a plurality of such springs and so dispose them that they may operate together or in seguence. So, too, in the train of mechanism intermediate the spring and the sleeve to be driven I may add or remove one or more wheels, whereby the parts may be operated for a longer or shorter period from the same spring, and, finally, in place of the mechanism described for winding up the spring I may employ an ordinary clock-key, the end of which is adapted to fit the socket in the shaft t?,
