Patented Sept. 3, 1940 DETACHABLE CLAMP SPNGE BRUSH-EES AND THE LLE '7 Claims.-

This invention relates to clamping devices, particularly of the type for holding sponge brushes, cloths and other pliable cleaning or rubbing elements.

One object of the invention is to provide a device of the character described including jaws movable toward each other for clamping action and improved means for mounting and actu ating the jaws.

Another object of the invention is the provision of a device of the nature set forth having a plurality of spaced clamps and improved means for mounting and actuating the same, with the actuating means being preferably operated by a single element. l

Another object of the invention is to construct a device of the type alluded to having a plurality of spaced clamps and an intermediate clamp, for simultaneously grasping different parts of an article, with the spaced clamps moving toward each other into clamping position as the intermediate clamp moves to clamping position.

Another object is to so construct the device that a single means actuates all the clamps, with the latter mounted for operation-as a unit.

Another object of the invention is to so construct the device that the closing of the spaced clamps causes them to move toward each other to cause closing movement of the intermediate 30 clamp.

Another object of the invention is to provide the device with a handle so resiliently coordinated with a clamp as to tend to open the same.

Another object oi the invention is to provide a device as set forth, with means adapted to maintain a spraying element within a clamp.

Other objects of the invention and advantages thereof will become apparent as the specication proceeds.

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the drawing: p

Figure 1 is a top plan view of a device embodying the invention, said device being shown in the closed clamping position, with parts removed and parts in section.

Fig. 2 is a view looking at the right end of Fig. l, with a fragment of a cleaning pad secured therein.

(Cl. 15J/31M) Fig. 3 is a similar view with the device in open position.

Fig. 4 is a sectional View on the line i--t of Fig. 2, but with the cleaning pad omitted.

Fig. 5 is a plan view with. parts in section of the spraying device.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several difierent constructions. `The accompanying drawing, theresi ci as showing the pre- :erred exenip icaticn of the invention.

Referring in detail to the drawing, l@ denotes a device embodying the invention. The same may include a frame li comprising a pair of members lf2, l5 which may be in the form oi box sections, each having an upright side wall, and the respective sections having top Walls Wa, i3d, and opposite end Walls lib, ith. These sections may be movably, prefer bly, swingably related to each other, as by pivotally interconnecting the end Walls lb, for instance, by rivets il. At the lower edges of the members i2, it each may have like confronting jaw portions, which may consist of a series of teeth l5 cifset relatively to each other as shown. Similarly formed on the members i2, 3 are the outer jaw elements, each desirably comprising a series of teeth iii for a purpose hereinafter described. Preferably the teeth iii are in alternate arrangement to the adjacent teeth the latter being bent inward and the intermediate teeth being bent outward.

Co-operating with the outer jaw elements it are the individual jaw members il, i8 of any suitable character, and being preferably straight and uniform to afford a smooth finish to the device lil. Each of these jaw members may be of angle shape to provide a part lying laterally beyond the points of the teeth l5, and a part overlying said teeth to form a stop for limiting the insertion of an article is to be clamped. EX- tending upward trom the jaw members il, i3 are their respective walls lla, its which lie along and outside of the sections l2, di Moveably,

sul.

preferably swingably mounting the jaw members sey members moves into clamping relation with its corresponding jaw element I6, and by exerting pressure on the latter, causes the sections I2, I3 to swing so that the inner jaw portions I5 move into clamping relation with each other. This action is facilitated by the provision of a common mounting or common pivotal axis at I4.

Preferably a common means is provided for causing the above described operation. For instance, each member IIa, Ia may partially marginally extend over its adjacent section I2 or I3 as the case inay be, and the members IIa, I8a may have projections or extensions IId, I8d respectively. `On the extension I'Id may be mounted a cam I9 rotatably connected thereto as at 20, and actuable by a knob or linger piece 2l. The extension Id may havean upright lip or follower 22 for said cam, the arrangement being that when the cam is turned to the position shown in Fig. 1, it abuts the lip 22 to force the extensions I ld, I Bd aaprt, and hence to cause swinging movement of the jaw membersl toward each other, to close the device IIB, as above described. When the cam I9 is given a quarter turn, the lip 22 is released, and the device IQ may be opened as shown in Fig. 3.

Desirably a handle is provided for the convenient manipulation of the device I0. Such a handle may be adapted for spring action, as by the provision of a U-shaped handle 23 having arms 24 terminating in outward projections 25 adapted to removably spring into suitable holes or recesses the cam i9 is moved to releasing position. For

this purpose, the wall I'Ia may have an offset open ended box-like element 26 having a flange 2l provided with a hole to receive one of the lugs 25. The other wall ma may have an upstanding ilange 28 protectively concealed in the element 26 and movable therein, said flange having a hole to receive the other lug 25. Accordingly the handle 23 is thus removably connected to the device I0 for manipulating the same, and the expansive action of this handle tends to resiliently move apartthe flanges 27, 28 to thus move the walls Ila, I8a, to cause the jaw members I'I, I8 to move apart to open position. It will be noted that the handle 23 may remain operatively connected to' thedevice IES regardless whether the same be in open or closed position.

If desired, a liquid supply or spraying device 29 may be utilized within the frame II. For example, the device 29 may consist of a tube longitudinally perforated at 3S, and suitably connected to a hose 3|. This device may be inserted into the space between the casing sections I2, I3 and may be resiliently engaged by U-shaped spring clamps 32 aiiixed to the case section I2 as at 33. By directing the perforations downward, a liquid may be uniformly imparted to an article held by the device I9, the sections I2 and E3 serving toretain any spray which may otherwise tend to flow in an undesired direction.

The manner of using the device II) will now be briey described. With the cam I9 turned at right angles to the position shown in Fig. 1, the spring handle 23 causes the jaws I'I and I8 to move apart and thus permits the case sections I2 and I3 to move so as to permit the inner jaw portions to move away from each other to open position. With the device I0 thus fully opened, this device is placed, for example, upon a sponge rubber" pad 34 or the like and is pressed downward upon the latter. Due to the softness and pliability of the pad 34, portions 34a thereof are squeezed into the space between the outer jaw elements I6 and their respective jaw members I'I and I8, with the top anges of the angular jaw members I'I and I8 limiting the upward movement of the portions 34a. Likewise a central pormove toward each other and hence toward their v corresponding jaw members I6. The portions 34a of the pad now become tightly squeezed with the teeth IE biting thereinto. The pressure exerted' on these portions 34a is thus naturally imparted by the teeth I6 to the case sections I2, I3 causing swinging motion of the latter with the jaw portions I5 moving toward each other so that the teeth I5 bite into the central upward bulging portion 34h of the pad. Hence the p-ad 34 is secured along three different lines, namely, along its opposite marginal portions and also along its central region. If the pad is to be removed, it is merely necessary to turn the cam VI9 to open position, whereupon the spring handle 23 causes the jaw members I'I and I8 to move apart so that the pad can readily be pulled out from between the various clamping jaws. It will be appreciated that ifA desired, the case members I2 and I3 may be held in iixed relation to each other,'and a desirable operation nevertheless obtained. It will also be perceived that for certain purposes the outer jaw members I'I and I8 may be omitted and the cam I9 utilized for direct actuation of the case members I2 and I3.

It will now be seen that I have provided a device which fullls the objects of the invention and is well adapted for practical use.
