4 Claims.

This invention relates to novel and useful improvements in systems for gathering refuse.

An object of this invention is to remove dandruff, small bits of hair and other foreign matter from the head of an individual by means of a system which includes at least one and preferably a number of cases suspended from the ceiling of a barber shop or mounted in another suitable location, each case having a drum therein with a hose on the drum and S disposed and arranged that upon pulling the hose from the case the movement of the hose from the case is opposed by a spring whereby the hose is springpulled back into the case when it is inoperative, and to incorporate in the system a switch mechanism which is rendered effectual and operated when the hose is pulled from the case, this switch controlling a valve which communicates the bore of the hose with a conduit, the conduit extending to a suction source and a refuse collecting receptacle.

Another object of this invention is to adapt the same structure for use in connection with other jobs such as cleaning furniture, the interiors of automobiles, valet use, and other environments.

Other objects and features will become apparent in following the description of the preferred form of the invention, illustrated in the accompanying drawings, wherein:

Figure 8 is a longitudinal sectional view taken throughlthe center of the typical suction-producing and refuse-collecting unit of Figure 1 which is suggested for use in connection with the apparatus; and

Figure 9 is a diagrammatic view showing the circuit diagram employed in the present invention.

Referring first generally to Figure 1, there is shown a building fragment I!) having a partition and a ceiling. Barber chairs l2 are shown properly aligned.

A housing, generally indicated at [4, is provided in a suitable convenient position and has, at the lower part, a drawer-type receptacle [6 slidable on tracks 18 within the lower part of the housing H. Disposed directly over the receptacle I 6 is a hopper 26 which is in direct communication with a chamber 22 defined by a fabric sleeve 24 which has its lower end fixed by means of a ring 26 or other suitable means above the hopper or funnel 26. The upper end is fixed by means of a ring 28 or by any other suitable means to the top part of the housing l4. Louvers 36 permitting air to pass through the walls of the sleeve 22 are provided intermediate the upper and lower ends of the housing it.

At the top part of the housing, there is a motor 34 forming a part of an air impeller which also includes a fan 36. This motor is supported in a suitable bracket 38 which is disposed in a suction chamber 46 formed by the walls 42. The walls are disposed within the outside shell of the housing [4 and there is a conduit 44 extending from the housing l4, that is in direct communication with the suction chamber 46. A suitable union 46 is used for connecting the corn duit 44 with the top part of the housing It.

One, and preferably more cases, generally indicated at 50, are suspended from the ceiling by means of brackets 52 or are otherwise suitably fixed to a wall or mounted on a stand which is disposed on the floor.

Each case 56 is identical in external and ill-=- ternal structure and configuration. A typical is fixed to the opposite Wall 62 of the case.

a part of a non-rotatable hollow shaft.

indicated at 66 and is passed through the bearing plate 66. hollow shaft is in direct communication with the conduit so that the air drawn through'the The said part 66 of the non-rotatable to the block I22 and the operator II 6.

conduit 44 is also drawn through the part 66 of the non-rotatable hollow shaft.

A drum 68 having bearing type flanges I and I2 projecting from the hub thereof is disposed for rotation on the hollow shaft. A hose 14 has one end fixed in communication with an opening I6 of the hub of the drum 68 which, in turn, is in direct communication with the hollow shaft formed by the two parts 64 and 66, respectively.

A clock spring 80 is fixed at one end on a post 82 to the drum 68 and the other end is fixed to a pin 84 which is secured to a spacer plate 86 fixed to the wall 62 of the case 50. Accordingly, upon rotation of the drum, the operation is opposed by the force of the spring, the spring constantly tending to return the drum after it has been rotated.

A ratchet mechanism (Figure is operatively connected with the drum to retain it in a selected position. This ratchet mechanism includes a ratchet gear 88 which is secured to the bearing 56 so that, upon rotation of the drum 68, the teeth of the ratchet gear 08 pass under the dogs 90 which are mounted for pivotal movement on the pins 9| carried by the drum 68. However, rotation in the opposite direction is impeded, this rotation being influenced and ultimately caused by the spring 80. The structure and operation of the ratchet mechanism is for the most part the same as a curtain rod ratchet mechanism.

The opening I6 which communicates with the inner end of the hose I4 has a valve 92 operatively connected therewith. This valve has a rod 94 fixed thereto and a spring 96 concentric with the rod 94. One end of the spring bears against the valve 92, while the other end bears against a solenoid case 98. This solenoid case is disposed in a small housing I00 which is fixed to the wall 58 of the case 50. A solenoid, generally indicated at I 02, is disposed in the said solenoid case 98 and has the rod 04 secured to the core thereof. Hence, upon operation of the solenoid the valve 92 is operated to open and close the inner end of the hose 94.

In operation of the device, insofar as air flow is concerned, when the solenoid I02 is operated, the Opening It is communicated through the part 68 of the hollow shaft with the conduit 44 so that the air impeller in the housing I4 may cause a flow of air through the hose I4.

The opposite end of the hose has a nozzle I06 secured thereto, This nozzle has a threaded neck I08 so that it may be removed from the threaded sleeve Ilt disposed at the end of the hose I4. Differently shaped nozzles may be substituted for different purposes.

Referring to Figure 2, a switch, generally indicated at H2, is illustrated in detail. This switch includes an operator or collar II4 which is fixed to the hose I4. Since the spring 80 constantly pulls the hose in such a manner that it tends to go into the case 50, the collar [I4 abuts the sleeve H6 which forms a part of the switch and urges it against the force of the spring IIO. These springs react on the operator II6 which is of electrically insulating material and a case I20 which is secured within the said case 50. The case I20 is also of electrically insulating material, as is the block I22 disposed therebelow.

Contacts I26 and I28 respectively are secured Hence, when the hose I4 is pulled from the case 50, the compression in the springs I I8 is relieved so that the contacts I26 and I28 become engaged.

By appropriate wiring, such as indicated at I30 and I32, the solenoid I02 is rendered operative as soon as the hose I4 is played out from the case 50 sufficient to allow the switch to become closed. By further appropriate wiring, for example by putting the impeller in series with the solenoid, the air impeller is rendered operative immediately upon operation of the solenoid so that suction is produced in the conduit 44.

Accordingly, it is only necessary to pull the hose 14 from the case to utilize the nozzle I06 for whatever purpose is found desirable. As soon as the hose I4 is pulled out of the case slightly, the solenoid is operated, thereby opening the valve 92; the spring is placed under a load opposing the operation of the drum 68 when the hose I4 is pulled out; and the air impeller is rendered operative so as to pick up the various undesired articles for deposit in the receptacle I6.

So that the hose I4 will be led through the central opening I40 in the member I20 and through the central passage in the operator II6, a pair of idler pulleys I42 and I44 respectively are mounted on suitable pins within the case 50 directly over the switch I I2.
