The present invention for which We filed an 1925, has for its object to provide means, with the aid of which mot-ion may beV transmitted from a reciprocating part such as a piston rod alternately to two or more other movable parts.`
The invention is principally ,distinguished by the fact that the reciprocating part, from which the motion is derived, has a carrier adjustably connected therewith, abutments being provided in the path of said carrier in such a manner that the carrier, when moved, is actuated by the abutment or abutments and is thus adjustedso as to hit the one or the other of the parts to which the motion is to be transmitted, the part in question beingA thus carried by the carrier. y
The parts to which the motion is to be transmitted are preferably connectedwith one another in pairs in such a manner that, when the one' part is carried in the one direction, the other part is actuated by the same for movement in the opposite direction.'
The device is suitable for different purposes, particularly for liquid meters having double vmeasuring vessels one of which is to be filled withthe aid of a pump while the other is at the same time to be emptied, the supply to the one vessel and the discharge from the other being alternately opened and closed. This is effected in the mostsimple manner with the aid of an adjustable cockplug, by which the two parts alternatelyreceiving the motion are connected, while the part provided with the carrier, from which the motion is derived, is directly connected with or forms the piston. rod of the pump.
The accompanying drawings disclose an embodiment of the invention as applied to a.
liquid meter. Y

' Fig. 5a showsthev same as Figs. la and 3a,
the cock plug bein'gin an entirely closed position.
Referring now, i more 4particularly to the drawing, there isfprovided a reciprocating member in the form of a rod 1V guided in guide bars 2, said rod being connected with or forming for instance the piston rod of a pump. 3 and 4 are two slidable members in the form of reciproca-ting rods guided in the guide bars 2, to which rods movement is" to be transmitted alternately from rod l. For `this purpose the latter rod is provided with the double-armed carrier 5 which is mounted to oscillate to and Afro about a pin 6 attached in rod 1. lThe carrier is retained in different angular positions, either by friction or by means of a-suitable locking` member. Rods 3 and 4 are connected, through a cord'or chain 7 eX- tending over a pulley 8 which .is attached to the spindle 9 of a cock plug 10. A Rods 3 and 4 are provided with lugs 11 and'12 respectively projecting into the path of the arms of the carrier. In their eXtreme positions said 'arms are stopped by a stop member 13 attached to the rod 1. A projection 14 onV the carrier cooperates with a rigid abutment which, according to Fig. 2 consists of the upper guide bar 2.
The device operates in thek following manner.
. starting position that the carrier 5 is pressed against theupper guide bar or abutment 2 and is thus turned intov a middle position, that is to say a non-oblique position. If the rod 1 is then moving downwards, the onegarm ofthe carrier hits that lug 11 or 12 on rods 3 and 4 which for the time being is inthe highest position. According to Fig. 1, this lug abutment 12 on rod el. Then the carrier struck the lug with its one arm, the carrier was turned by reason of the resistance and was broughtinto an oblique position, so that, on the continued downward movement of the carrier, the other arm of the latter moved freely past the lug 11 on rod 3. Rod et was then carried downwards, while rod 3 was pulled upwards actuated by the cord 7. The result of these movements is disclosed in Fig. 1. Then the rod 1 again moves upwards, together with the carrier 5, the obliquely set carrier will still move freely past the lug 11 of rod 3, and the projection 14 of the carrier is finally pressed against abutment or guide bar 2, whereby the carrieris turned into the normal position according to Fig. 2. Then rod 1 and the carrier again movedownwards, the carrier 5 hits the lug 11 of rod 3, which abutment is then in the highest position. rlhe carrier is adjusted owing to the resistance and is brought into an oblique position, so that its continued downward movement is not hindered by the lug 12 on rod l. The latter is pulled upwards, when rod 3 is carried downwards by the carrier. The ultimate result of these movements is disclosed in Fig. 3. In this way the rod 1 will, with the aid of the adjustable carrier, transmit movement alternately to rods 3 and 4:.
Then the invention is applied to a liquid meter of the type set .forth and is provided with an adjustable cock device, it is assumed, according to the drawing, that rod 1 is connected with or forms the piston rod of the pump, and that the rotatable pulley 8 is attached to the spindle 9 of the cock plug. If 15 designates the inlet of the cock, 16 and 17 the inlets thereof to the measuring vessels, and 18 and 19 the outlets of the cock from the measuring vessel, then the measuring is effected as follows. Then the piston 1 moves upwards from the position according to Fig. 1, an amount of liquid will be forced in through the inlet 15, said liquid movingfurther through the inlet 16 to the one measuring vessel, while an amount of liquid escapes at the same time through outlet 19 (Fig. 1a) from the other measuring vessel. Then the piston rod 1 then moves downwards and carries the rod 3 along with it, after the carrier has been adjusted against the abutment or guide bar 2 hereinbefore described, the cock plug 10 will be adjusted into the position according to Fig. 3 or 30. respectively. Then the piston rod moves back upwards, that is to say when it makes its pump stroke, an amount of liquid is forced in through the inlet 15, and moves further through the inlet 17 to the emptied measuring vessel, while the measuring vessel filled on the previous pump stroke is simultaneously emptied througih outlet 18. The inlets and outlets of the liq- Vpump rod will be completely locked.
uid meter are thus adjusted alternately on each successive pump stroke.
The amount of liquid forced into the measuring vessel in question on each pump stroke will be dependent on the length of the pump stroke. The arrangement in question makes it possible in a simple manner to alter the quantity which is thus to be measured. 1f the carrier 5 is permitted to move freely between the guide bars 2, one of which forms the abutment for the adjustment of the carrier, a certain maximum quantity will be measured. If the movement of the carrier or the pump stroke respectively is shortened, the quantity will be less, and this is effected in a simple manner by a displacement of the abutment of the carrier. If the abutment is displaced into a position right between the guides 2, which can take place, according to the drawing, by inserting an additional abutment 2O in the said place, the pump rod 1 can move only half the way, and the measured quantity will be half as large as before. In this way the abutment can be displaced to any point desired, according as a larger or smaller quantity of liquid is to be measured.
The arrangement ensures that the meter cannot be adjusted so as to effect wrong measurements. t is conceivable that the carrier may be manually adjusted so as to actuate the two rods 3 and t simultaneously in a middle position, as shown in Fig. 5. If this takes place, all channels of the cock will be closed, as will appear from the drawing, and when the pump rod is again to be moved upwards, together with the carrier, in order to effect pumping, this is rendered impossible, in that the cock does not permit passage of liquid in any place. Consequently, the
Pumping cannot, therefore, take place if the carrier is not first brought into such a position as to actuate the rods in the normal way.
That we claim is 1. In a device for the transmission of movement`r a reciprocating member, a pair of slidable members adapted to be moved alter- -nately in opposite directions, a carrier mounted for oscillation ou the reciprocating member, a projection on the carrier, lugs on said slidable members positioned in the path of movement and engageable by the carrier, and an abutment coacting with the projection ou the carrier and adapted after engagement of the carrier with either of the lugs to shift said carrier to normal position.
2. An arrangement as claimed in claim 1, wherein a rotaryv member is provided, and a fierible element trained about the rotary member and connected with the slidable members so that when one member when moving in the one direction will actuate the other so that it will in turn move in the opposite direction and incidentally impart alternate rotation to said rotary member.
3. An arrangement as claimed in claim 1, wherein the carrier is double armed and rovided with abutting surfaces, and an a utment is mounted on the supporting point of the carrier and provided with a straight edge forming a stop which coacts with the abutting surfaces on the carrier so as to determine the possition which the carrier occupies after it has moved against said straight lo edge.
4. An a-rrzuigelnent as claimed in claim 1, wherein upper and lower guide bars are pro vided to guide the reciprocating and sliding members7 and the upper guide bar forming the abutment which coacts with the projection on the carrier, substantially as and for the purposes set forth.
In testimony whereof we ax our signatures.
