JACOB KURTZ, OF GREENSBURG, PENNSYLVANIA.

STRAINER FOR MINE-PUMPS.

SPECIFICATION forming part of Letters Patent No. 705,364, dated July 22, 1902.

Application filed April 26. 1902.

To all whom it may concern,.-

Beit known that I, JACOB KURTZ, a citizen of the United States, residing at Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Strainer for Mine-Pumps, of which th-e following is a specification.

This invention relates to an improved strainer to be used in Connection with a suc tion-pump; and the object thereof is to provide an efcient devicejcapable of ready attachment t0 or d etachment from the free end of the hose or pipe that is connected to the pump proper.

Another object of my invention is to provide a device in which the strainer will be protected against injury and one in which all danger of the strainer becoming clogged is positively avoided.

With these briefly-stated objects in View my invention comprises certain details of construction andvnovel combination and arrangement of parts, as will be fully described in the following specification and pointed out in the claims, reference being had to the drawings, in Which- Figure l is a perspective view of my improvement as in use. Fig. 2is a longitudinal section of the casing or box with the strainer proper in position. Fig. 3 is afront elevation of the box. Fig. 4 is a detail plan view of one end of the box, and Fig. 5 is a detail section taken about on the line 55 of Fig. 3.

In the drawings I have shown my invention as used in a mine; but ofcourse it will be understood that the same may be used with equal effectiveness in places where itis desired to draw off Water, and in carrying out my invention I employ a box or casing A Whose sides are perforated, as shown atA,

and at the rear of the box I provide guide-y strips A2, in which is slidably retained a door B, that is also perforated, as shown at B', the upper end of the door being provided with a finger-hold by which the door is readily rei moved when desired. Within this box or casing is arranged the strainer C, that has its periphery perforated, as most clearly shown in Fig. 2 of the drawings, and whose front end terminates in a contracted neck portion C', in which is adapted to be held the inn er Serial No. 104,834. (No model.)

end of a flexible hose or pipe D, that is connected at its opposite end to a suitable suction-pump. (Not shown.) The strainer C is supported above the bottoni of the box or casing A by means of wooden legs E, and above the strainer and at one end thereofI arrange suitable brace-strips F, that securely andv firmly hold the said' strainer in position within the casing.

The forward end of the easing is provided with a sliding clamping-block G, that operates in groovesr A3, arranged in the box or casing-A, and is rmly held in position by a woodenscrew H, that has an arm H' projecting laterally therefrom and which is adapted for engagement by a pin H2, that is fitted in an aperture arranged in the top of the said box or casing. This block G has a portion of its lower face cut out, as shown at G', said cutout portion being arranged opposite a eutout portion G2, formed in the lower or base block I, that is firmly held in the" casing, as shown. By this arrangement the hose .or pipe D is firmly clamped to the boxor casing Av and itsextreme endi'irmly held within the neck portion C of the strainer.

In practice I prefer to construct the box or casing, the slidingrblock,the screw,`and the door'allof wood, whilethe strainerC, is preferably'constructed of glass, and it'is'for this -purpose that I providethe 'strainerwith a shield 1 or casing such as described, and of course it vwill'be understood that the door B is forthe purpose 4of 'obtaining access tothe box Whenever desired.

Myinvention is particularly adapted for use in flooded mines, andin order to hold the vbox or casing rmly in position I employ a suitable prop or brace J, that is positioned against the roof of the mine and the top of the casing, which rmly holds the box or casing in position. y From the foregoing the simplicity and ad vantagesof my improvementwill be readily understood, and it will be particularlynoted that by arranging the rdoor as described Ythe hose may be quickly and easily 'attached Yto or detached from the `strainer,'it" only being lnecessary to remove the pin H2, when the screw may be reversed, the block raised, and the hose or pipe withdrawn and the strainer removed, and by arranging the pin against which the arms of the screw strike the screw may be firmly and securely held in position to which it has been adjusted.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent of the United States, is-

1. A device of the kind described, comprising a perforated box or casing having guide- Ways formed in the ends thereof, a sliding door arranged in one end thereof and having a series of apertures produced therein, a strainer arranged within the casing, a hose or pipe connected to the strainer, and means arranged in the forward end of the box or casing for firmly clamping the hose in position, substantially as shown and described.

2. In a device of the kind described, the combination of a box or casinghaving its sides provided with apertures, a strainer arranged within the said box or casing, braces arranged within the box and adapted for engagement with the said strainer, legs arranged Within the casing upon which is adapted to rest the said strainer, the sliding door arranged in one end of the casing and having a series of perforations formed therein, a hose connected to the strainer, a stationary block held in the forward end of the casing, a sliding block arranged above the said stationary block and adapted for engagement with the hose, and a screw arranged in the top of the casing and adapted for engagement with the block, and means for holding the said screw in its adjusted position, substantially as shown and described.

a movable block held in the said guides and having a recess produced in the lower face thereof which is adapted to register with the recess in the first-named block, a screw operating in the said box or casing and adapted for engagement With the said movable block,

arms carried by the screw and a pin arranged y upon the casing and adapted for engagement by one of the said arms ofthe screw, and means arranged Within the box or casing for holding the said strainer in position, substantially as shown and described.

4:. A device of the kind described, the combination of a box or casing, a strainer held therein, a hose connected to the strainer, a clamp carried by the box or casing and engaging the said hose, a sliding door arranged in the casing opposite the said clamp and a prop or brace engaging the said casing and mine for holding the said casing in position, substantially as shown and described.

JACOB KURTZ.
