GEORGE- COLVIN KENNEDY, OF WATERLOO, IOWA.
FORCE-DELIVERY SYRINGE.
Application filed January 16, 1918.
To all whom it may concern:
Be it known that I, GEORGE OoLvIN KEN- NEDY, a citizen of the United States of America and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Force-Delivery Syringes, of which the following is a specification.
My invention relates to improvements in force-delivery syringes, my improvement is to provide means for successfully operating the mechanism of the syringe from a distance.
This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:
Figure 1 is a vertical central longitudinal section of the vessel and its supporting means of my improved force-delivery syringe, parts being broken away; Fig. 2 is an upper plan view of'the same; Fig. 3 is a front elevation of the supporting-means for said vessel and of the traction-means, and Fig. 4 is a perspective view of the guidebrackets.
Similar numerals of reference denote'c'o'rresponding parts throughout the several views.
The numeral 1 denotes a hollow cylindrical vessel, having an open upper end, and a closed lower end of conical form 3 terminating in an orificed nipple 4 upon which one end of a flexible tube 30 is mounted, the other end of said tube being supplied with a detachable delivery-nipple 31.
The upper end .of said vessel is thickened at 2 to provide an annular ledge or fillet. The numeral 5 denotes a back-plate having at its upper end a hanging orifice 6, and also having a plurality of holes 7 to receive nails or screws whereby the plate may be fixed to a wall or other supporting structure. The numeral 8 denotes a ring or sleeve which is riveted or spot-welded to said plate 5 to extend horizontally therefrom, and the vessel is mounted in said ring with its fillet 2 seated on the upper edge thereof, removably.
Opposite to the plate 5 a bracket 9 is riveted or spot-welded or otherwise fixedly mounted on said ring, and has its upper and Lower parts bent in the same direction horizontally forward, to provide flat arms 10 and 14 which have vertically alined orifices 11 and 15 and other vertically alined smaller orifices 12 and 16, and the extremity of the Specification of Letters Patent.
and the object of Patented July 8, 1919.
Serial No. 212,037.
.The numeral 21 denotes a piston mounted to move through said vessel 1, and is provided with a circumferential groove to detachably receive an inner annular rib on an elastic packing-ring 22 to hold the ring on the piston securely and prevent leakage between it and the inner wall of the vessel.
Said ring 22 preferably has a depending lower edge, which may be coned' as shown, whereby the liquid confined under pressure of the descending piston will exertpressure against the depending edge to seal thesame to the 'vessel wall to aid in preventing leakage. The piston has a central socketed' bossv 26 'todetachably receive the lower end of alpiston-rod 27 the latter having a transverse orifice'25 alined with transverse orifices 24 in said boss, said orifices receiving a splitkey 23'v remov'ably.
Theupper part of said piston-rod 27 is bent laterally horizontally past the vessel then bent downwardly vertically to depend adjacent to the forward wall of the vessel through the orifices Hand 15 of the guidearms 10 and 14 slidingly.
The numeral 28 denotes a ring fixed on the depending o reversely-bent part of said piston-rod above the arm 10, and has a hook to receive a' loop made in the upper end of a flexible traction-cord 20, the latter depending through the orifices 12 and 16 in the arms 10 and 14, and having its other end secured to the nipple'31. In Fig. 4 is shown a modification, in which a small pulley-block 18 is swingingly mounted on the lower arm 14 by means of a link 17 inserted in the orifice 16, and the cord 20 is passed about the sheave in said block, whereby the sheave acts as anti-friction bearing means for the cord, and which permits traction to be applied from a distance to the cord, and from a horizontal or other direction, to operate the piston in forcing it downwardly without difficulty.
It will be perceived that when the pistonrcd is pushed down the reversely-bent part will slide in the orifice in said guide-arms without binding, and will guide the piston 21 in its movements to prevent the latter tilting or binding in said vessel thus preventing any leakage or difficulty in its operation.
The user can actuate the device from a distance, by means of the traction-cord 20, which renders the same useful in hospitals or in other places, an d ,especially in locations where the syringe must be nountedat a low level where a gravity-delivery would not be possible, and traction maybe varied at Will to propel liquid from the delivery-nipple 31 with a desired force.
Having described my invention, what 1 claim as new, and desire to secure by Letters Patent, is:
1. In a device of the character described, a vessel provided witha delivery port, a piston in said vessel, supporting-means in \vhichsaid vessel ;is re novably mounted, said supporting-means including aguideway, and a piston-rod connected ,to said piston, .extendingswithout the -vessel,r,having outward part reversely bent andlslidably n10 unted insaid guideivay.
2. In a device of the character described, a vessel hZLXillg ,a delivery-orifice, a piston in said vessel, a ,pistonerod ,on said piston having its upper ,part projected from ;the vessel and bent .tO one side, supportingn eans in which said vessel is removably mounted, ;-a guideway on said supportingmeans in whichthe .bent part of said; pistonrod is slida-bly mounted and .ti actionemeans connected to said piston-rod for moving it downwardly operable from a distance.
In adevice/of thecharacter described, a vessel having its lower end closed and provided with an outlet-port, a piston movable in said vessel, a piston-rod detachably connected 4'00 said piston, projected through the upper endof the vessel and bent over to one side, supporting-means for said vessel, guides on said supporting-means for the bent-over partof said piston-rod, said guides having an orifice, and a traction-cord connected to said piston-rod above said guides and passeddown through the orifice therein.
a. In a device of the character described, a vessel having its lower end provided with a delivery-port, a piston in said vessel, a pisto rrod ,on said piston having its upper part bent reversely over to extend .dOWnwardly at one side of the vesseha guideway having alined orifices ,to receive the bent? over part of said piston-rod s lidin gly, a pulley swingingly mounted on said guideway, a traction cord connected to said piston-rod above said pulley and passed downwardly about the sheave in the pulley, a flexible tube in co nmunicatiqn with the deliveryport of said vessel, and said traction-{cord having its other end cQll iected to said flexible tube.
Signed at ,lVaterloo, Iowa, this 12th day of Janua-r 1918.
