Specification of Letters Patent.

Patented oct. 22, 191s.

Application filed October 29, 1917. Serial N o. 199,137.

To all whom t may concern Be ity known that I, NICHOLAS CHOU- VALDJY, a citizen of the United States, residing at Berkeley, in the county of Alameda, State of California, have invented certain new and useful Improvements in Guspidor-Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others sldlled in the art. to which it appertains to make and use the same.

This invention is an improvement in lifting devices and has particular reference to a cuspidor carrier.

An object of the invention is to provide an improved carrier employed to lift a cuspidor and convey the same to any desired place where it maybe cleaned without the necessity of the operator at any time handling the same and, to this end, use is preferably made of a pair of pivoted jaws adjustable toward and away from each other and supporting gripping elements adapted to engage a cuspidor and relative to which the jaws are adjustable, whereby the same may be swung to a position at substantially right angles to the carrying position thereof to permit cleaning of the cuspidor without detaching the ygripping elements therefrom. Another object is to provide improved means for locking the jaws and consequently the grippingelements in their operative or cuspidor supporting positions.

Ay further object is the provision of improved means for locking the jaws against relative movement Withrespect t0 one of the gripping elements after said jaws have been swung to' a position topermit of cleaning the cus idor.

A still further object is to provide a device of this character which is simple in construction, easy to manufacture and effective in carrying outthe purposes for which it is designed. j

The inventive idea involved is capable of receiving Ya variety of mechanical expressions one of which,1for the purpose of illustrating the invention, is shown in the ac-v companying drawing, wherein:-

Figure l is an elevational view of the carrier showing the position of the same when the jaws have been adjusted to permit of cleaning the cuspidor.

' Fig. 5` is a fragmentary longitudinal sectional view Of the carrier.,

' Fig. 3 is a fragmentary perspective view partly broken away and shown in section of one of the gripping elements and the mechanism for locking the jaws against movement relative to said gripping element, the parts being shown in unlocked position.

Fig. 4 is a perspective view of a portion of the jaw adjusting mechanism.

Fig. 5 is a fragmentary longitudinal section taken at right angles to Fig. 2.

The drawing illustrates what is now believed to be a preferred form of the invention which comprises aI hollow tubular shank 10 having one end 11 enlarged and the material of which said shank is made is extended to providey the oppositely disposed and laterally projecting arms 12 bent at their outer ends to provide the side 13 of the handle of the device which further includes the grip 14. The opposite end of the shank 10 preferably has secured thereto a coupling l5 including spaced side flanges 16 arranged in parallel relation and longitudinally of the shank and disposed in planes parallel with that of the handle of the device. The outer ends of the lianges 16 have aA pivot bolt 17 mounted therein for supporting adjacent ends of oppositely extending curved jaws 13. The aws are further provided adjacent their pivot ends with the enlarged heads 19 to which are connected the ends of coil springs 20 which extend transversely of the iianges 16 and interiorly of corrugations 2l formed therein. These springs 20, which are arranged on both sides of the heads 19, are adapted to normally draw said heads together whereby to spread the opposite ends that the same will at all times of the jaws so it is debe in position to be operated when sired to lift and carry the cuspldor.

Preferably threaded upon the ends of the jaws 18 opposite the heads 19 are bearing sleeves 22 for receiving` the Shanks 2.3 of the arcuate gripping elements 24 which have strips of felt or rubber 25 embedded in the inner surfaces thereof so as to securely engage a cuspidor. The shanks 23 are disposed radially with respect to the elements 24 and the shank of the element shown at the right of Fig. l has slidably mounted thereon a small disk 26 yieldably held in engagement with the outer end of the bearing 22 by means of a coil spring 27, said disk having a rod or projection 28 thereon which is adapted to engage in a notch formed in the ing longitudinally outer end of said bearing when the gripping element is in a position at right angles to that shown in Fig. 1 or, in other words, when the device is in position for carrying the cuspidor from one place to another. j By means oi' this construction it will be apparent that said gripping clement will be tricvionally held in said position.

lvleans are provided in connection with the gripping element shown at the lett of Fig. 1 for positively locking said element in a plane with the jaws 18, as shown in said ligure, and also for trictionally holding said gripping element in aplane at right angles to 'said jaws, as when carrying the cuspidor Jfrom one place to another. rllhis means preferably comprises a collar or nut 29 mounted to slide on a squared extension 3G ot the shank 28 and having a projection 31 atY its inner end adapted to engage a notch 32 in the bearing 22 when the gripping elements are in the position shown in Fig. 1, said projection being yieldably held in engagenient withA the bearing by means ot a coil spring interposed between the collar 29 and nut mounted upon the outer end of the extension 30. ln order that the gripping element 241 may be rictionally held in a position at right angles to that shown in Fig. 1, as inV Fig. 3, the outer end of the bearing 22 is provided with a small depression or notch 35 tor receiving the project-ion 31, and by reason of the shallowness of said notch it will be apparent that the jaws 18 may be swung about the shanks Q3 as pivots without manipulating the head 29 to discngage the projection 3l trom said notch and it will be apparent that when. the jaws and gripping element are in the same plane, the projection 31 will auton'iatically engage the notch 32, by reason of the coil spring thus locking the parts in the position shown in Fig. 1.

rlheV mechanism for adjusting the free ends ot the jaws and gripping elements toward each other in order to engage a cuspidor preferably comprises a rod 36 extendot the interior of the shank and having one end projecting through the coupling 15 and into the space between the iianges 16, said end being provided with a wedged shaft head 3T the inclined edges otwhich engage the projections 3S of the heads 19 of the jaws sothat when the rod-36 is n'ioved longitudinally in one direction the heads 19 will be spread apart andthe otherends of the jaws adjusted toward each other. The end of the rodBG oppositethejwedge 37 projects beyond the end 11 of the shank and has slidably mountedY thereon an adjusting member 39.131'0- vided atone end with the laterally extending armsdforming aiinger grip while the intermediate portion ot the member is formed with the oppositely disposed locking keys ieeaoae Li1 arranged in the saine plane with the arms #10 and adapted to normally engage the dia-- metrically disposed slots 12 formed in the end 11. the keys or wings 41 prevent rotary movement of the adjusting device relative to the rod 36 and the arms Ll() will then extend in a diagonal plane with respectY to that oi the handle or'A the device. A nut 43 is mounted upon the upper end of the rod 36, and interposed between said nut and linger grip, formed by the arms 410, isa coil spring 411 which is adapted to maintain the inclined surfaces ot the wedge 37 in engagement with the projections 38. y

ln practice, when it is desired to litt a cuspidor and carry theV same to a suitable place for cleaning, the` operator grips the handle port-ion 11 in one hand and engages the arms 10 with the ngerV of said hand and then pulls upwardly upon the adjusting device B9 so as to adjust the rod 36 longi tndiually of the shank 10 and cause the wedge 37 to spread the heads 19 of the jaws against the tension of the spring 20. lhen the gripping elements 24E are engaged with the cuspidor and the keys 11 have been disengaged from the slots 12, the adjusting device 39 is given a slight rotary movement to cause the inner ends of the keys to engage and rest upon the inner ends of the arms 1Q of the handle. During this operation the gripping elements 24 are disposed at right angles to the jaws 18' and as soon as the cuspide-r is securely engagedhy said elements the Vsame may be carried to any desired place. Before cleaning the cuspidor the jaws. 18 `are swung about the shanks 28 ot the grippingelements as pivots until the parts are inthe position shown in Fig. 1 whereupon the jaws 18 and element at the left in said figure are locked t0- gether, as previously described, and' free access may then. be had to the interior.v of the cuspidor so that the same may be readily and quickly cleaned.
