TTORNEY United States Patent DRIER FOR HAIR BRUSHES Girolamo Mangilo and Fred H. Schreiber, West Islip, N. Y.

Application September 9, 1954, Serial No. 454,992

1 Claim. (Cl. 34-495) The subject of the invention described in this patent is a novel and valuable drying device especially adapted to be used in beauty parlors, barber shops and like establishments, for quickly and conveniently drying, at one and the same time, and by the use merely of heat and air under pressure, a plurality of hairbrushes' after washing and sterilization of the latter.

In such establishments, particularly those of the better class, each patron expects that a new hairbrush will be used by the beautician or tonsorial artist serving that patron, and, indeed, in most if not all States in this country, that a new hairbrush be used for each patron served. By a new hairbrush, of course, is meant either a new one or one which after being last previously used has been cleaned and made sterile.

In the case of a hairbrush which in connection with its sterilization has been washed, such hairbrush, naturally, must be dried after washing; and where, as is often the case, many different patrons are served in a single working day, the problem of maintaining on hand the required supply of previously washed and sterilized and now dried hairbrushes' has been troublesome and expensive. Ordinarily, a completely wetted hairbrush takes a long time to dry. Yet a very considerable investment is required in order to have on hand the large total of hairbrushes needing to insure that a sufficient number of dry ones will always be available; and, besides, fairly extensive shelf areas or other supports for brushes previously wetted and so needing to be dried are required.

In attempts to avoid the difficulties just indicated, dry sterilization, as by the use of formaldehyde vapors, or by the use of ultraviolet light rays, have been resorted to. The thought here has been to avoid soak-wettings of the bristles of a hairbrush for fear of permanently softening the bristles.

We have found, however, that this fear is wholly unfounded, provided only that after full wetting and even after soak-washing the bristles of a hairbrush, the bristles are subjected to the passage thereover and through the interbristle spaces of a stream of high velocity, highly heated air. A stream of the kind so defined is that de livered by a standard blower with heater unit such as is commonly used in driers for womens hair, as after shampooing and washing in a beauty parlor or at home.

Therefore, according to the present invention, we have been able to devise an exceedingly simple and relatively inexpensive device for drying in very short order several, and indeed a great many if desired, of wet hairbrushes; and a device, moreover, which may incorporate a standard blower with heater unit of the kind above mentioned, but which, nevertheless, is adapted to have dried brushes removed therefrom and additional wet brushes inserted during operation of the device on brushes remaining therein and still not fully dried.

The device of the invention comprises, essentially, a cabinet having a first opening, means for delivering heated air under pressure incorporating a blower and a heating "ice unit for discharging a stream of heated air into the cabinet for sweep therethrough, a door normally closing a second opening through which hairbrushes may be inserted into and removed from the cabinet, and a third opening for coacting with the internal shape of the cabinet and with a supporting means for hairbrushes therein in desired placements, to insure that said air stream will be directed to sweep over the entire plurality of hairbrushes in the cabinet. Devices pursuant to the invention as above have been made and successfully used in operatnig beauty shops, said devices for drying at one time from sixteen to forty-eight hairbrushes.

Other desirable objects and the novel features through which the various purposes of the invention are attained are set forth or will papear in the course of the following specification.

The drawings accompanying and forming a part of the specification illustrate two practical mehodiments of the invention now favored, but it will be appreciated that structural changes of various kinds are possible, all within the true intent and broad scope of the invention as hereinafter defined and claimed.

In said drawings,

Fig. 1 shows one of said embodiments in perspective, looking toward an end of a horizontally elongated cabinet at which is located the aforesaid third opening.

Fig. 2 shows said embodiment mainly in side elevation, with parts broken away to illustrate sectionally certain features, and to suggest the comparatively great length which the cabinet may have and so to indicate its capacity for drying at once a large number of hairbrushes;

Fig. 3 is a transverse vertical section, taken on the line 3-3 of Fig. 2.

Fig. 4 is a top plan view, partially broken away and partially in section, illustrative of the other of the two practical embodiments hereinabove mentioned.

Fig. 5 is a vertical section, taken substantially on the line 5-5 of Fig. 4; and

Fig. 6 is a horizontal detail sectional View, taken on the line 6-6 of Fig. 5.

Referring now to the drawings in more detail, and first to the form of the invention exemplified by the structure illustrated in Figs. l-3, a horizontaly elongated cabinet 15 is shown, which conveniently is of the quadrilateral cross-section indicated in Fig. 2, and which desirably, as also there indicated, is formed of a suitable plastic. The cabinet 15, it will be noted, is somewhat wider than high; and, as shown in Figs. 1 and 2, the cabinet is of a length at least several times its width. In the successful use of an embodiment of the invention exactly as shown in Figs. l-3, a large number of hairbrushes were relatively quickly dried at one time, with the brushes arranged side by side and with each brush extended lengthwisely in the direction of width of the cabinet interior. Said brushes were placed with their bristles pointing upward, and were simply laid down on supporting means inside the cabinet and to be described later; which supporting means were precisely the same in said successfully used device as shown in the drawings herein.

An inlet opening 16 for the stream of heated pressuredriven air is provided in an end wall 17 of the cabinet, as shown in Fig. 3.

A large opening 18, as long as and almost as wide as a side wall 19, as best shown in Fig. 2, is provided in the said wall 19.

In the end wall of the cabinet opposite to the Wall 17, said opposite end wall being marked 20, there are upper and lower louvre openings 21 and 22. As more clearly shown in the case of the latter, at the left-hand side of Fig. 2, these openings are so shaped that their inclusion in the cabinet 15 if molded of a plastic will present no difficulties or complications because of the presence of the louvre members or hoods such as the one designated 22a. It is also to be noted that the sum of the crosssectional areas of the two openings 21 and 22 is relatively small as compared with the area of the opening 16, with the result that while successive increments to the stream of heated pressure-driven air discharged into the cabinet will all in time escape one after another through the openings 21 and 22 there will be present in the cabinet what may be called a pile-up of the heated air with a consequent quick evaporization of the moisture in the wet hairbrush bristles thereby to dry said bristles in a remarkable short period of time.

This action occurs, of course, while the large opening 18 is closed; and so as normally to maintain that opening closed, a swing-door 23 is provided, hingedly mounted on the cabinet 15 as indicated at 24. The pintle-carrying portion of said hinge is located, as shown clearly in Fig. 3, well above any table-like support on which the cabinet 15 is placed, due to the provision of four rubber feet 25, each readily attachable to the plastic cabinet 15 as by use of a machine screw 26 in the manner illustrated at the left in Fig. 2 The swing+door 23 is normally held closed by a pair of leaf-spring latch pieces. 27, shaped for snap engagement with the side wall 19 along the upper edge of the opening 18 in said wall. For convenient manual release of said latch pieces and swing down of the door 23 to open condition, two pull-knobs 28 are provided, anchored in place by the same screws, as shown in the case of one of said screws at 28a in Fig. 3, which are included in the means for securing the latch pieces 27 in place at the inner side of the door 23.

The blower with heater unit is as a whole designated 29, the blower casing being illustrated as flanged and there attached by screws to the end wall 17 of the cabinet as shown in Fig. 2. At 30 is indicated the air inlet tube for the blower, and at 31 the electric switch for throw to energize the motor of the blower or to deenergize said motor. At 32 and 33 respectively are shown the shaft and the vanes of the blower. It will be noted that, while as already pointed out the sum of the cross-sectional areas of the two hot air escape louvre openings 21 and 22 is relatively small as compared with the area of the opening 16, the area of the last named opening is conside'rably greater than the cross-sectional area of the heated air stream discharged from the vanes 33; with the result that the watery vapors resulting from the aforesaid quick evaporization of the moisture in the wet hairbrush bristles have adequate egress ways provided therefor at the four corners of the opening 16.

These good results were had even with, as herein shown, the structure of Figs. 1-3 constructed so as interiorly thereof toprovide two compartments, an upper one 34, and a lower one 35; so that there could be dried at one and the same time two tiers of hairbrushes with each tier arranged as already described; that is, placed with their bristles pointing upward and simply laid down on supporting means while said brushes were arranged side by side and with each brush having its length extended in the direction of width of the cabinet interior. Said supporting means were, as herein shown, two wall structures in the nature of horizontal partitions. Each of these is herein shown as molded of a plastic, to include, in addition to its main wall, on which the hairbrushes are laid, a pair of depending stiffener-spacers. In the case of the upper partition, this for flooring the upper compartment 34, said main wall is marked 36, and its said stiffenerspacers are shown at 37; it being noted from Fig. 3 that these parts 37 are of inverted U shape to provide passages for travel of the heated air stream through the lower compartment 35. The lower partition, this for flooring the said lower compartment 35, comprises a main wall 38 and stiffener-spacers. 39.

The bottoms of the said stiffener-spacers 39 rest slidingly on the upper surface of the bottom wall 40a of the cabinet; and the bottoms of the stiffener-spacers 37 rest slidingly on the upper surface of the lower partitions main wall 36. Thus, for over about the middle third of its length, the lower partitions main wall 38 is supported for being slid laterally relative to the width of the interior of the cabinet 15, and, also, for about the middle third of its length, the upper partitions main wall 36 is supported for being laterally slid relative to the width of the cabinet.

Auxiliary supports for the ends of said walls 36 and 38 are also provided, whereby when said walls are fully inserted into the cabinet their ends will be firmly upheld, yet whereby either of said walls may be sidewisely slid into and out of the cabinet, in the latter case, particularly, to permit all dried brushes on either wall 36 or on wall 38 or on both walls to be removed from the cabinet in the brief interval of time required to swing down the door 23 and slide out a selected one of said walls, or both said walls simultaneously.

Said auxiliary supports for the ends of the wall 38 are comprised of a pair of upper and lower horizontal ribs 40 and 41, spaced apart by slightly more than the thickness of said wall 38, and with one pair of said ribs directly opposite and alined with the other, and with each of the cabinets end walls 17 and 20 having one of said pairs of ribs formed on and projected inwardly therefrom. The auxiliary supports for the ends of the wall 36 also comprise pairs of ribs, horizontally arranged like the ribs 40 and 41, and with the ribs of each pair spaced apart by slightly more than the thickness of said wall 36, and with these pairs of ribs also alined and partially carried by the inner sides of the end walls 17 and 20 of the cabinet. Here, however, as will be noted from a comparison of Fig. 3 with Fig. 2, wherein all the upper ribs of pairs of ribs for engaging the ends of Wall 36 are designated 42 and all the lower ribs of said pairs are designated 43, there are in effect two pairs of said ribs on the cabinets end wall 17, this due to the opening 16 in that wall, although there need only be one pair of these ribs 4243 on the cabinets end wall 20.

With the cabinet 15 made of plastic as described, and with the partitions carrying the main walls 36 and 38 also of plastic, and, furthermore, with the door 23 of plastic, as indicated in Fig. 3, the cabinet is of such light weight as to be easily lifted; and handle means at the opposite ends of the cabinet are present to facilitate easy and convenient portage of the device. Said handle means at one end of the casing is constituted here by the air inlet tube 30, and at the other end of the casing by the louvre member or hood 22a or by both such hoods.

Referring next to the form of the invention shown in Figs. 4-6 here, there is shown a drying device according to the present invention, and one which, when constructed to the size indicated, also may be used for the drying at one and the same time of a very large number of hairbrushes. In referring to hairbrushes herein, the reference, of course, is to a hairbrush of ordinary or common ly accepted size; that is, the well-known size manufactured for and sold generally to beauty parlors, barber shops, etc.

It will be noted that in the drying device of Figs. 4-6, the cabinet, which is marked 15', is cylindrical. From what has hereinabove been said, and in view of said shape of the cabinet, the structural characteristics of the embodiment of the invention shown in Figs. 4-6 will be readily seen, if it be pointed out that in the last-named views the parts respectively corresponding in function to parts shown in Figs. l-3 are given the same reference numerals but with primes added.

Spaced around the side wall of the cabinet 15', about 270 from the opening 16' for the admission into the cabinet of the stream of heated air under pressure, are the louvre openings 21' and 22'; the louvre members or hoods associated with these openings being seen at 21a and 22a.

Spaced around said side wall of the cabinet, about from said opening 16', is a large opening corresponding in function to the side wall opening 18 of Fig. 2. The said large opening in the cabinet is normally closed by a door 23 hingedly mounted as at 24. Said door, in any section thereof taken radially of the axis of cylindricity of the cabinet 15', with the door swung upward about its hinge mounting through 180, is of horizontally inverted L shape; and as will be noted said door is so shaped that when lowered the large opening at the side of the cabinet is fully closed, as also is the large segmental area of the top of the cabinet shown in Fig. 4 as located below the center line of the pintle of the hinge 24'.

For latching the door 23 closed, the two leaf spring latches 27 engage with ribbed formations at appropriate places on the exterior of the cabinet 15 as shown in the case of one of said formations at 27a in Fig. 5. Manual lifting of the door 23 is aided by presence of the louvre members 21a and 22a, which may be used as pull-up handles for releasing the leaf spring latches 27'. The door 23' is, of course, only to be opened while dried brushes are being removed from the cabinet or while brushes to be dried are being inserted into the cabinet.

The blower with heater unit is as a whole designated 29, and is arranged as shown and suitably secured to the cabinet so that the heated air stream therefrom will be delivered in substantially a tangential direction into the interior of the cabinet through he opening 16'; the air inlet tube for the blower being marked 30 and the electric switch for turning the blower on being marked 31. At 32 and 33 respectively will be noted the shaft and the vanes of the blower.

The cabinet 15 is divided into upper and lower annular compartments 34- and 35, so that there may be placed in each of these compartments a plurality of hairbrushes 44, with these brushes arranged radially of the axis of cylindricity of the cabinet interior as shown in Fig. 4, and with each brush somewhat lengthwisely downwardly inclined to have its bristles at lower level than its handle as shown in Fig. 5.

Said compartments are established, and means for quickly and easily placing the hairbrushes in the cabinet in said compartments as just described are afforded by providing a central upstanding drum 45, by rotatably mounting this drum by means of ball bearings 46 on a central vertical stud 47 screwed into securement with the bottom wall of the cabinet as shown in Fig. 5 by fixing on said drum upper and lower annular trays 48 and 49, each of these having an outer vertically upstanding circular flange 48a or 49a, and by providing a large plurality of recesses 50 along the length of the drum as indicated in Fig. 5.

As will be noted, these recesses 50 in each compartment 34' and 35 are arranged in two circular series, one series above the other; so that in each compartment every other hairbrush circumferentially of the compartment may have the free end of its handle pocketed in a lower recess 50 and the intervening hairbrushes may each have the free end of its handle pocketed in an upper recess 50. Then the converging of all the said handle ends will not require too great spacing of the bristles-end of one hairbrush from the bristles-end of the next adjoining one, and consequently the number of hairbrushes to be dried at one and the same time in each compartment may be kept at the maximum, with, at the same time, a suflicient such spacing provided for that: the upstanding bristles on the outer ends of the successive brushes in a circumferential series will react as the vanes of a rotor and so cause rotation of the structure comprised of the drum 45 and the two trays 48 and 49 in response to curvilinear sweep through the cabinet of the stream of heated air under pressure entering the cabinet through the opening 16. Not only will this heated air stream act quickly to dry the bristles of the brushes, but in doing so it will continually cause the entry of new brushes into the zone of its maximum drying eflicacy, with the result that in a remarkably short length of time a very large number of brushes previously placed soaking wet in the cabinet will all be dried and uniformly dried and with the drying of all of them substantially simultaneously completed.

It will be understood that the invention may be embodied otherwise than as herein specifically illustrated or described, and that various changes in the details of construction and in the form and arrangement of parts of the illustrated embodiments may be made within the scope of the appended claim Without departing from the underlying idea of the invention.

What is claimed is:

A drying device for hairbrushes and the like, comprising a cabinet having a first opening, means for delivering heated air under pressure incorporating a heating unit and a blower, means for mounting the first-named means on the cabinet at said first opening in position to discharge a stream of heated air through said opening into the cabinet for sweep therethrough, said cabinet having a second opening and a door openable at said second opening to permit insertion into and removal from the interior of the cabinet of a plurality of hairbrushes or the like, said cabinet having a third opening to provide an escape means for said heated air stream and said third opening being so located as to coact with the internal shape of the cabinet to insure that said air stream will be directed to sweep over the entire plurality of hairbrushes in the cabinet, there being wall structures in the cabinet to subdivide the latter into a plurality of compartments each for housing a plurality of hairbrushes to be dried, and means for mounting said wall structures in the cabinet while permitting movement of such a structure relative to the cabinet, the cabinet being horizontally elongated, said first opening and said third opening being respectively at opposite ends of the cabinet, and there being a pair of handles for facilitating portage of the device, said handles being respectively at the opposite ends of the cabinet, a portion of said heated air delivering means projecting beyond the cabinet and thereby adapted to constitute one of said handles, there being a louvre member for providing the other of said handles and the louvre opening associated with said member providing said third opening.
