NJPETERS4 PHOTO-LITHOGRAPHIE, WASHINGTON. D. C,
dinard @gewas H. LOCKWO'OD, OF CHARLESTOWN, MASSACHUSETTS.
Letters Patent No. 94,620, dated September 7, 1869.
IMPROVEMENT IN SYRINGES.
The Schedule referred to in these Letters Patent and making part of the same.`
This invention has two objects, one being to securethevalves of syringes from accidental displacement and loss, while leaving them free for cleansing, and
the other being the transfbrmatimi ot' a syringe-bulb,.
having two openings, each in the line and at the end ot its long diameter into an elastic sac or bulb, having but one opening therefrom, which opening is `supplied with a pipe, serving alternately for a suction and a delivery-mpc. i
'.lhe tirst part of my invention consists in the detail by which I secure the. valves from accidental displacement, while, at the same time, they may be easily rcmoved t'or cleansing.
The second part otA my invention consists in such a construction and arrangement of' the parts of a syringe having two openings in the bulb, oneI at each end of' its long diameter, as enables meby mere dismemberment ot' such syringe, and by thc transfbr ot' its parts, to produce a simple il1jectiug-instrumeut for the :nlmiuistratiou of given quantities ofmlaiieiual enemas, such as laudanum, for example. Simple injectinginstrnments, made np of" an elastic sac or bulb, bavingl but one opening provided with a tube, have been in use for some time. lberetbre, the second part of my invention is confined, as before stated, to such ,a construction and arrangementof' the parts ot' a syringe employing an elastic sac or bulb, having two oritices, as will produce a simple injecting-instrument, by the dismemberment of' such a syringe and the rearrangement of lsome ot' its parts, thus enabling me to t'nrnish two instruments in one at the price of one.
Figure l, of the drawing, shows, in sectional elevation, a syringe having au elastic bulb or sac, with an orifice at each end, the sac being provided with flexible tubes and a valvular system, and a suitable injecting-tube; i'
Figure 2 shows, in sectional elevation, a simpleinjecting-instrmnent, malle up of' parts ot' the syringel shown in tig. ll and Figure 3 shows the device by which the valves ot' the syringe are kept from displacement and loss.
The sac or bulb, lia-ving orifices, one lat each cud, is
marked a, parts ot' valve-boxes, l) and c, being inserted,
one in each orifice.
These inserted parts are made with both nut and screw-threads, as shown, so that on the screw-threads may be coupled the part-s land e, which complete the valve-boxes, said 4parts having suitable necks, to which the flexible suction and exit-pipes f and g are attached.
Ou the end of the suction-pipe f, an end piece of metal .is coupled, to sink it in any tiuid to be injected, while on the end of the exit-pipe g, a piece, h, is coupled, to which delivery-tubes of any size or forni are screwed, there being in said piece, two nut-threaded holes, arranged at right angles to each other, one of' said holes being stopped by a screw-plug,l t', the delivery-pipe being screwed iut-o the other hole.
The screw-parts ot' the plug i, and the delivery-pipe j, being of the same size with the nut-threads in the 4 piece l1, are interchangeable therein, and being also of the same. size with the nut-threads in pieces b and c, can at any time be removed from piece h, and located iu pieces b and c, as shown in lig. 2, the iiexible pipes and the parts d and e, first heilig removed from the bulb, the delivery-pipe. jv being inserted in piece c,
which has no 'alve, and the plug 'i being/inserted in piece b, rendering the valve therein inoperative for any use or purpose in the organization seen at figg?.
rlhe valves la and I, ot the syringe, are each kept f'rom accidentally falling fi'om the valve-boxes when they are dismembered, by a short bar or wire'o, said pieces being made ot' such lengths and shape at their ends, that theyl can be turned in the nut-tln'eads ot' the parts b a-nd e. p
These wires o are so located in the nut-threads as to permit the valves to rise from their seats suiiciently to allow free flow of', fiuid past them when the sac a, is ,operate-d. Y
When the valves and their seats need to be cleansed, the wires can be removed byvturning them out ot' the unt-threads, and then,- when the cleansing is effected, the valves and the wires can be replaced.
This simple and inexpensive device operates efiiciently in preventing loss of valves, beretoibre so troublesome in syringes.
l claim- In combination with an elastic syringe-bulb, having an orifice at each end, pieces c and b, provided each with screw/and rmt-threads adapted to receive 'the coupling-pieces d and c, the plug yi, andthe pipej, substantially as described.
Also, the combination, with the valves and valveboxes, of a syringe, of the wires o, applied within the screw-thread, substantially as and for the purpose specified.
