To G/ZZ whom it mag concern:

Be it known that I,-EUG NE O. M. HABER- AOKER, of Altoona, in the county of Blairja'nd State of Pennsylvania, have invented a newand useful Improvementin Fan Attachments for Rocking-Chairs, of which the following is a specification. w

This invention relates to certain useful im provements in fan devices for rocking-chairs. The object of the invention is to provide such a device that can readily be by any person applied to any chair the body of which is adapted to be rocked on the floor or a supporting-base, as is obvious.-

I am aware that the broad idea of providing a rocking-chair with a fan attachment adapted to be operated as thechair is rocked to and fro is not broadly new and to all of which now provided there is more 01' less 0bjection for one or another reason, and therefore I have devised a fan-attachment needing no special skill to properly affix it in Working position on a chair and such a device as is adapted to be adjusted into position for operation or folded back out of the way and, locked against operation, thus permitting free use of the chair with the fan device in an in-- operative position obviating liability to break: age, all as hereinafter fnlly'described, and shown by the drawings.

Briefly stated, my fan attachment is so constructed that it may be adjusted to force the air toward or from the occupant of the chair. In fact it may be set in a vertical, oblique, or horizontal position, forcing. the air in any desired direction. I

To the end above stated, I

described, and shown in theaccompanying drawings, with the novel features pointed out in the claims.

Referring to the drawings, Figure l is a perspective view of my fan attachment. Fig. 2 is an enlarged detail of the upper end of the fan attachment.

1 fer'red means. I vided'with a downwardly-extending wing or 7 have invented the special fan attachment hereinafter fully Fig. 3 is a detail plan view. of the fan-holder. Fig. 4 is a section on line- Fig. 5 is a view showing the? In carrying out my invention I employ a lowercastin'g is formed with a socket D, fitted into that end of the casing A and secured by a fastening, such as a screw-bolt aor other pre- The said casting is also propro'jection E, riveted or otherwise secured to a plate b, having hinge connection with an L'-shaped plate F, which latteris arranged on a rocker or other-suitable support of a chair. Thisplate F, I have shown secured in place by a screw passing through-the horizontal member thereof and up into the rocker; but obviously said plate may beotherwise suitably secured. The hinge connection of plate I) with L.-shaped plate Fand the pivotal movement of the wing E on the rivet enables vertical'adjustment of the device with relation to the .curve or angle of the rocker.

The upper casting B (see Figs. 6, 7, and 8) is formed; with a similar socket G, entering the casing A, and is secured in place by a screw ,0, having a rounded-head, if desired,

which latter is received by an annular internalgroove d, formed in the casing. By this construction the casting B is permitted rotation and still secured against withdrawal. The casing A is provided with an opening (1 to permit the screw 0 being aflixed to the socket-G after the same is arranged in the casing A. One side of the socket Gris cut away, forming a passage-way f registering 'with a vertical passage 9 through the top of the casting. At the bottom of the socket the passage-way is bridged,as at f against which latter-the rod H rests and is held firmly when the jamrscrew t has locked the said rod H in position. The top of the casting B has a threaded passage h at right angles with the passage g,,-adapted to receive. the jam-screw 't' for locking the rod H, whose function is to hold thefan I to an ad justed-po'sition, as hereinafter described. The rod H is arranged and supported in the casting B so as to lie within the inner wall of the casing A, and

into the casing A, as will be more fully described farther on. The fan adopted by me consists of four, more or less, vanes k, whose arms enter sockets as shown, of a plate Z, and the said arms are secured against rotation by a clamping-plate m, forced against them by a nut 01, threaded upon the project ing end of the rod J. The rod J is provided with a flexible member 0 just below the fan I. This flexible member (see Fig. 2) consists of a spirally-wound wire having at both ends detachable connection with the rod J, such as threaded sockets 0, (shown in Fig. 2 of the drawings;) but I do not desire to limitmyself to such construction, as such connections may be made permanent, if desired. The

purpose of detachable connection is to allow removal of the said flexible member 0 when desirable. By means of such member the fan I is adapted to be adjusted toa vertical, oblique, or horizontal position and so held by the rod II, which is connected with the rod J by rigid arm P, extending at an angle from a sleeve Q. The latter is loosely mounted on the rod J above the flexible member 0. As before stated,the lowerend of the rod J passes down into the casing A, where it connects with mechanism inside the casing A, as will appear farther on.

Within the casing A and about half-way thereof I secure a special casting R, held by screws 19 or other suitable means. The upper end of this casting Risdisk-shaped, forming a bracket q, and the upper side is recessed, as at r, forming one member of the special clutch shown in Figs. 6 and 10 of the drawings. In detail this clutch consists of a toothed wheel affixed to a sleeve 25, passing up through the bracket q,and balls u, arranged in the space formed by the inclined walls of the teeth and the flange surrounding the recess 1' of the bracket q. The halls u are held in place by a cap n, which, if desired, maybe integral with the toothed wheel. Within the upper end of the sleeve t is loosely arranged the lower end of a tube w, whose upper end within the socket G of the casting B is provided with an enlargement a and then extends through the openingfof the said casting B. The projecting end of the tube to is tapered and screw-threaded, as at X, and provided with one or more slits extending to the end thereof, allowing the tube at this place to be contracted by a not b screwing thereon, and thus clamping the rod J, which passes down through it into the tube w. The nut b is held to its adjustment by a jam-nut c, as shown. The sleevetand the enlargement a, the latter near the upper end of the tube w, are connected by a spiral spring A. I have shown the ends of the spring secured to the said sleeve and enlargement by being reduced in diameter and closely encircling the said parts,with the ends of the spring being bent at right angles and engaging a recess thereof; but any other means may be employed that will provide a rigid connection. As will be seen from the drawings, the sleeve 25 extends down through the bracket q and at its lower end is provided with a disk d, formed with a depending tooth 0 The lower end of this sleeve is internally reduced in size by a socket f, which receives the upper end of a spiral rod 13, whose lower end is stepped in a cup-shaped bearing 0, having threaded adjustment in the casting C. Within the bearing 0 may be arranged a leather or other soft disk to receive the thrust of the lower end of the spiral rod B when said rod drops, disengagingjthe clutch members d a The clutch member a is rigid with thespiral rod B and has two or more upwardly-projecting teeth b Upon the disk a is arranged a soft packing c slightly thicker than the length of the teeth on said disk (L The object of this yielding packing c is that when the spiral rod is rotated and the disk a. is raised the upper member of clutch willbe rota ted by disk 01 because of the friction provided by said packing before the teeth 12 and 0 come in contact. On the spiral rod B is arranged a sliding block or sleeve D. The passageway through the sliding block conforms to the shape of a cross-section of the spiral rod, permitting it to slide thereon, whereby an alternating rotary motion is imparted thereto in the moving up and down of the block. The sleeve D is forced up and down by a rod E, that passes down through a slot in the lower casting C and is connected with a roller F which is exterior to the sleeve D and in operation rests upon the floor. The upper end of said rod E is connected with a lug formed on the sleeve D. The pin passing through the roller may be formed of an angular extension of the arm or rod G, whose rear end is pivoted to the adjacent rocker of the chair, as shown in Figs. 1 and 5. At the said pivot a spring (Z is arranged to exert force on the rod G, tending to hold the roller on the floor.

In Figs. 6 and 7 of the drawings between the bracket q and the upper member d of the clutch I arrange a washer, which may be replaced by a thicker one to take up wear.

Referring to Fig. 2 of the drawings, it will be seen that the rod H for holding the fan in different positions is connected with the fanshaft or rod J by a link H, one end of which is rigid withthe rod H and the other end is loosely connected with and slides on said rod J.

The sliding block or sleeve D (see Figs. 6 and 7) is provided with a spring (2 whose free end bears on the spiral rod B, the object being to hold the sleeve D by friction and prevent rattling of the spiral rod.

To prevent the spiral spring A kinking or curling up against the sides of the rotating tube 10, I surround the said spring with a light tube f resting loosely on the cap 4; of the upper member of this clutch device. In other words, the said tube is used only to confine the spring A, not forming any part of working mechanism. I

A suitable opening may be made in the casing for oiling and inspecting the clutch devices, as shown at 3, Figs. 1 and 5 of the drawings.

Hereinbefore I have referred to the fact that the working parts,which I will call as a whole the motor, may be locked against operation. For this purpose I provide a locking-plate J ,conforming to the inner shape of and pivoted to the middle casting at 4:, Figs. 6 and 7. A knob 5 onthe locking-plate extends through a slot in the casing. To adjust the locking device into operative position, the knob 5 is moved upwardly, which action throws the upper end of the plate under the lower member of the clutch device and moves the latter upwardly, bringing the teeth on the disks (1 and a into engagement. This action does not interfere with the upward movement of the sliding block and the forward to tation of the spiral rod and clutches, but prevents the lower clutch member dropping out of engagement with the upper member, and thus the spiralrod is prevented from rotating backward, and consequently the sliding block, driving-rod, and roller are held suspended at their highest points, in which position the mechanism is locked and inoperative.

In operation when the knob 5, projecting through the casing, is moved downwardly the locking-plate J is slipped from under the disk forming the lower member of the clutch, allowing said member to drop out of engagement with the upper member. The spiral rod is now free to rotate backward. The roller carried by the rod E drops to'the floor, carrying with it the sliding block to its lowest point on the spiral rod. Upon a forward motion of the rocking-chair the sliding block lifts the spiral rod by reason of the friction of said spring on said block until the yielding packing on the upper face of the lower clutch member is brought into contact with the under surface of the upper member of the clutch, compressing said packing, and by the adhesive contact and sometimes partial engagement of the teeth of the clutch members rotates the sleeve 25, making five or six revolutions thereof, and thereby winding the spring .A to that extent at its lower end. Upon the first backward movement of the rocker the balls in the upper clutch are forced outward, locking the clutch, and thus preventing a re verse motion of the said sleeve t. During the above-described operation the upper free end of the coiled spring A continues to unwind itself, carrying with it the tube w and the fanrod J. The resistance of the air retards revolution of the fans, and thus prevents exhaustion of the power stored in the spring A un til said spring again receives a fresh impetus and by repetition of the rocking motion of the chair the rotation of fans becomes continuous. In other words, the fans will revolve until the power stored in the spring is exhausted. When the knob of the lockingplate is raised, the upper end of said plate again engages the clutch mechanism, and

thus suspends further operation of the motor mechanism, as hereinbefore described. The motor device is held in working position (see Figs. 1 and 5 of the drawings) bya springcatch 6 engaging collar 7, adjustably arrangedon the casing, and when said device is folded back, as shown in Fig. 5 of the drawings, it is supported by a hook 8 on the rear leg of the chair.

Attention is called to the fact that by reason of the special construction and arrangement of parts carried by the upper casting B said casting may be turned in the upper end of the casing, and thus point the upper end I of the fan-rod when deflected so as to force the air in such direction as may be desired.

It is obvious that my fan attachment will work with equalfacility upon either side of fmeans telescoping as stated and adapted to be revolved around the fan-support, a motor employing a spiral spring having one end fixedly connected with the fan-support and the other end adapted to be wound through clutches connecting it withdriving devices, and means such as a rigid rod extending from the floor with yielding bearings thereon substantially as described.
