PUMP.

Specificaton of Letters Patent. Patented May 9, 1911 Application filed January s, 1910. Serial No. 538,?57.

Te (zZZ whom 'it may concem:

Be it known that I, JonAN SIGISMUND FAsTING, a subject of the King of Denmark, residing at Frederiksberg, near Copenhagen, Denmark, hare invented certain n'ew and useful Improvemcnts in Pumps, of which the following is a spccification, reference being had to the accompanying drawing, forming a part hereof.

This invention relates to means for operating pumps of the general character of that shown in Letters Patent of the United States, No. 315,171, dated April 7, 1885. In pumps ot this character there is no piston but the pump harrel i reciprocated somewhat rapidly so that. by reason of the inc'tia other fluid pumped, the pump barre] is moved more rapidly than the water or other fluid. Such pumps are particularly adapted tor use as mud or sand pumps, but arc obviouslr capable of use for pumping water, air-orany fluid or material which has the general' characteristic of fluidity.

In accordance with the invention the pump burrel is reciprocated rapidly by means of an eccentrie weight mounted to rotate upon a movablc ax is which is connected to the pump burrel, so that the latter partakesof the rapirl reciprocations or vibrations imluced by the rotation ofsuch eccentric weight about the movable axis of -otation.

The invention Will be more fullyexplaiued hereinafter with reference to the cmbodiaccompanypump barrel is reciprocated rapidly, the valve 2 is moved from its seat clownward movement, or other relative movement, of the provided such movement 'of the pump barrel is more rapid of the liquid in the same influence of gravity or prcssure from any other source, and during the upwarcl or other relative movement of the pump barre] the valve is closed and the liquid is moved upward or forward. In this nanner an upward or forward pulsating flow of the liquid or fluid through the valve 2 and the pump barrel 1 is obtained, and it will be obvious that the strength of the flow will depend mainly on the rapidity of the pulsations. To ctfect the desired reciprocations of the pump barrel, there is provided an eccentric weight 5 which is rotated rapidly by any suitable means, as by a belt pulley G upon which theweight is mounted and a belt 7, and the arci's of rotation of the weight is supported in suitable bearings which are movable in a longitudinal direction with the pump barrel, such movable axis or movable bearings therefor being con- 'rccted with the pump barrcl 1 so that the latter is reciprocated with the rcciprocations of such axis or bearings which are induced by the rapid rotation of the eccentric weight. As shown in Fig. 1 the bearings 8 of the axis of rotathe pump barrel l or to an extension -thereof, with respect to the pump barrel, pump barrel itself` being thus movably supported, pal-takes of the reciprocations of the movable bearings of the eccentric weight.

In Fig 2 the a check Valve 2 the liquid to be ciprocations by by a link 9 with the bcarings 6 which carries the eccentric driven by a belt 7.

ing drawing in which` Fgrc 1 is a View in Outline, representing one embodincnt of the invention, and Fig. 2 is a similar View, representing another emhodiment ot' the invention. l e In the embodiment of the invention representccl in Fg. 1 the tube or pump barrel 1 is shown as having near its lower end a check' valve 2 opening upward and as supported by spri'ngs 3, secured to a fixed upport 4, so that the pump barrel may reciprocate in. a longitudinal direction. The pump barr-el. in this case, is shown as supported in which rest upon a a vertical position and as having its lower ciprocations of the cnrl directly immersed in the liquid to be of rotationof the pumpcd, but, as will be obvions, it. might be supported in any other position and might be connected through a flexible pipe, or' otherwise, with the body of liquid to be pumpcd. As will be understood, when the and shown as immersed in moved, s guded n ts re- 8 of the pulley weight 5` and is In this case the bearings fixed support 8. The rebearings 8 or of the axis unbalanced or eccentric also the discharge shown as mounted upon the fixed support 8 and as connected with the pump barrell by longitudinally movableand are therefore movable 'longtudinally so that the c) the axis of rotation of guides 10 and is connected,

8 are supported movably upon springs 8 I 105 during the tion of the weight are Secured directly to pump' barrel 1 provided With Weight 5- are therefore transmitted to the pump barrel through the link 9. 'In this case pipe 12 of the pump isg a flexible pipe 11. The discharge pipe is also shown as provided With a check valve 13 and with an air chanber 14:. Obviously the check valve 2 may he located at any convenient point and the pump burrel may be reciprocated in a right line or in a curved line.

Various other modifieations in the construction and arrangement of the parte will readily suggest themselves and it is understood, therefore, that the invention is not restricted to the particular Construction and arrangement shown and described herein.

I claim as my invention:

l. The combination with a punp ban-el capable of longitudinal reeiprocation and a check valve therefor, of an eecent'ic rotatable Weight and bearings for the axis of rotation of the Weight novable longitudinaliy with the pump burrel and connected there- 1 with, whereby the pump burrel is reciprocated with the reeiprocations of said bem'- ings induced by the rotation of the eccentric weight.

2. The combination with a pump barrel eapable of Iongitndinal 'ecip'rocation and a check valve therefor, of a pnlley having :n eccentric weight and be 'ings fol' said pulley connected with the pump ha''ei, whereby the pump'harret 'eeiprocates with the reciproeztions of said benrings indnced by the rotztion of the eccent'ic weight.

In witness whe'eof, 1 have hereunto signed mynznne in the presence of two subscribing witnesses.
