Application January 10, 1942, Serial No. 426,353

' 4 Claims. (01. 15 40) This invention relates to a fire hose washer and has for an object to provide a device of this character which will wash and scrub conventional fire hose of the one and one half inch type, or the two and one half inch type, either in the conventional fifty foot length or a plurality of lengths coupled together.

A further object is to provide a device of this character in which the hose may be fed into and between the brushes by a fireman standing at one side of .the device, and may be withdrawn by a fireman standing at the opposite side, the device being so constructed that the hose may be backed and run through the device as many times as may be necessary until the hose is completely cleaned of any adhering soil.

' A further object is to provide a device of this character in which the brushes are arranged in opposite pairs to wash and scrub the top and bottom sides, as well as the edges of the hose, the brushes being carried by a reciprocating frame which moves lengthwise of the hose to simulate manual scrubbing which is usually accomplished by washing fire hose with a broom or stiff brush on a concrete floor and this is a slow and tedious process.

' A further object is to provide a device of this character which will be formed of a few simplestrong and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order. 7 v

. With the above and other objects in view the invention consists of certain novel details of con struction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a top plan view of a fire hose washer constructed in accordance with the invention.

Figure-2 is a longitudinal sectional view taken line 5-5 of Figure 2 showing the slides, guides therefor carried by the end plates, and the crank and pitman connection for reciprocating the brushes.

Figure 6 is a detailed cross sectional view showing a hose in position between the brushes.

Figure 7 is a detailed perspective view showin one of the slides connected to the brush carry ing frame for reciprocating the frame longitudinally of the hose.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, It] designates an open frame through which the hose II is fed by two firemen standing at opposite sides of the washing machine. As best shown in Figure 2 the frame is rectangular and comprises vertically disposed end bars l2 and I3, and horizontally disposed bars I4 and I5.

Upper and lower brushes l6 and H, see Figure 6, are secured to the upper and lower bars of the frame by clamp bars l8 and [9, see Figure 2, and the clamp bars are bolted to the frame bars as shown at 20 to permit renewal of the brushes when worn out. The brushes-clean and scrub the upper and lower sides of the hose while the hose is passing between them. The brushes are adjustably secured to the frame H] for adjustment toward or away from each other to receive various sizes of fire hose, and for this purpose vertical rows of openings 2| are provided in each end bar to interchangeably receive the upper and lower securing bolts 22 of the upper and lower bars.

Brushes 23, for cleaning the sides of the hose, see Figure 1, are adjustably secured to the end bars l2 and I3 of the frame I0 through themedium of superposed horizontally extending bars 24 which are provided with respective rows of openings 25, see Figure 2, to interchangeably receive bolts 26 passed through openings in the end bars. Each brush 23 is clamped between clamp bars 21, see Figure 4, by bolts 28 passed through the bars and the brush to permit replacement of the brush when worn out. As shown in Figure 7, the clamp bars 21 are secured to the respective superposed adjustably mounted bars 24 by bolts 29.

Side plates 9 are provided at the front and rear sides of the device, these plates being of substantially rectangular contour. The plates are provided with respective openings 8, see Figure 6, through which the hose is trained to pass between the brushes.

Pairs of substantially rectangular plates 30 are located at opposite ends of the brush carrying frame I0, see Figures 1 and 2. Horizontal guide bars 3| are fixed to the confronting faces of each pair and slide plates 32, see Figure 2, are mounted in the guides formed by the guide plates. Arms 33 are fixed to the end bars of the brush carrying frame and pass through slots 34 in the innermost plates of each pair, see Figure 2. The slots incline downwardly and inwardly to prevent the water sprayed on the brushes and hose from reaching the slide plates 32. The arms 33 are fixed to uprights 35, see Figure 7, carried by the slide plates 32. the slide plates are reciprocated the brush carrying frame III will be reciprocated longitudinally of the hose to carry the brushes correspondingly to effect thorough scrubbing and cleaning of the hose.

For reciprocating the brush carrying frame l0 an electric motor 36 is mounted on a base plate 31 to which the side plates 9 and end plates 30 are secured. The speed of the motor is stepped down and transmitted to a crankshaft 31 through the medium of a small pullley 38 on the motor shaft 39, the small pulley being connected by a belt 4!], see Figure 3, to a large pulley 4| carried by a stub shaft 42 which is secured to one of the end plates 30 and which is equipped with a small pulley 43 which is connected by a belt 44 to a large pulley 45 on the crankshaft 31. The crankshaft is equipped with cranks 46 which are located between the respective pairs of the end plates 30, see Figure 1, and the cranks are connected by pitmans 4'! to wrist pins .8, see Figures and 7', on the respective slide plates 32.

superposed pairs of tie bolts 49, see Figures 1 and 4, connect the pairs of end plates 30 together.

superposed pairs of spray pipes Ell extend through the end plates 30 at one end of the device and are located on opposite sides of the upper and lower brushes l5 and H, see Figure 4. Each pair of spray pipes is connected at one end to a vertically disposed pipe 5|, see Figure 2.. The vertically disposed pipe El is connected to the end of a horizontally disposed pipe 52, see Figure 1, and this pipe is. connected to a. supply pipe 53 for supplying water in the form of jets or sprays to both the hose and the brushes Simultaneously.

Since, the operation of the parts has been described as the. description of the parts progressed it is thought. that. the invention will be fully understood without further explanation.

What is claimed is:

1. A fire hose washer comprising a vertically disposed open frame through which the hose being washed passes, said frame having upper, lower and end bars, brushes for cleaning the sides of the hose carried by the upper and lower bars of the frame, brushes for cleaning the edges.

of the hose carried. by the. end bars of the frame, means for adjusting the brushes of each pair toward or away from each other to effect proper contact, of the brushes with the hose, plates located at opposite ends of the brush carrying When frame, horizontal guides carried by the plates, slide plates mounted in the guides, uprights on the slide plates, arms secured to the end bars of the brush carrying frame midway their ends and engaged through slots in the plates and fixed to the uprights on the slide plates, means for reciprocating the slide plates to reciprocate the brush carrying frame longitudinally of the hose, and water spray pipesdisposed on opposite sides of the upper and lower brushes for supplying water to both the hose and the brushes during reciprocation of the brushes.
