Specification of Letters Patent. Patented Dec, 13, y1910.

Applicationled August 5, 19.10. Serial No. 575,631.

To all whom it may concern:

Be it known that I, ROBERT lVALTHER, a citizen of the United States of America, re siding at North' Side Pittsbur in the county of Allegheny and State o Pennsylvania, have invented certain new and useful Improvements in Trick Drinking-Mugs, of

y Which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a trick 'drinking mugor receptacle, and the object of the invention is to provide a mug or receptacle With a rim formed With a plurality of passages and a series of openings communicatv in with the passages, one of the passages being blind, while the other constitutes the outlet passagel for the liquidrthe outlety passage communicatin with the bottom of the mug through the andle thereof. The plurality of openings at the rim will mystfy the user of the mug, unless the user is familiar with that outlet through which the contents of the vessel is discharged under such conditions preventing the contents of the mug or receptacle from being drunk ex- Y cept in a prescribed manner, the contents of the mu or receptacle being otherwise spilled to the iscomiture of the person attempting to drink out of the mug or receptacle when not familiar' with the construction of the same.

A further object of the invention is to provide a trick drinking mug or receptacle 1n a manner as hereinafter set forth that will afford considerable amusement topersons observing the use of the mug by a person not familiar with the same, the construction of the mug and manner of obtainin the contents thereof perplexing and mysti ying the user to thatextent that it almost seems.

' rim, the

having the upper edges thereof provided with a tubular enlarged rim 2 and connected to said rim is the upper end of a tubular handle 3 having the lower end thereof connected to the side of the receptacle 1 at the bottom thereof.

The tubular rim 2 is provided with two partitions 4 and 5 and the passage 6 between the partitions 4 and 5 has one end thereof terminating in a nipple 7 formed lntegral with the rim 2 and the opposite end in communication with the passage or by-path 8 of the handle 3, the lower end of the passage or by-path 8 communicating Awith the interior of the mug or receptacle 1.

'lhe remaining passage 9 of the rim 2 is in communication with openings 10 formed in nipples l1 resembling the ni ple 7 of the passage 9 being a b ank passage that deceives a person attempting to use `the mug.

yThe mug or receptacle 1 adjacent to the rim 2 has the walls thereof lprovided -with a plurality of openings 12 these openings preventing the contents ot the mug or receptacle being drunk in the ordinary manner, since'the contents of the receptacle would immediately fiow through the openings when the receptacle is tilted or inclined.

The tubular handle 3 adjacent to the rim 2 is provided with an air vent 13 in communication with; the by-path 8.

To successfull drink the contents of the mug or receptac e 1 the handle?) is gripped in kthe left hand with the foreinger or thumb over the air vent 13. By then placing the mouth over the nipple 7, the contents' of the receptacle can be drawn throu lh the bv-path 8 into the passage 6 and into t e mouth. With the mouth upon the rim' 2 and the receptacle elevated by the left hand, it appears as though the contents of the ref ceptacle were passing overl the rim 2 into`A the mouth, while in reality the ,contentsof y the receptacle 'never reach the openings 12, otherwise the contents of the receptacle would be spilled.

Since the nipple 7 is located on the righthand side of the handle 3, the mug orreceptacle cannotbe used by the ri ht hand, unless the vent 13 is closed by the eft 1hand. This would hardly occur, as in the majority of instances the mug is sim ly held by one hand, generally the right and, .and it is this very fact that first deceives the-user of the mug. Even though-the air vent 13 is discovered it is then a question as to which of the nipples Z or 10 to place to 'the mouth. The mug or receptacle can be made of porcelain, china or vitreous material and finished according to ones esthetic taste.

y From the foregoing it will be observed that I have devised a trick drinking mug having a hollow rim towhich the contentsy of the receptacle are conveyed exterior of the receptacle, the means employed for conveying the contents constituting. a lgrip or receptacle having the 'Walls thereof preu vided withvopenings at a point removed from the upper edges of said receptacle, a rim carried byF said `receptacle and provided with a pair o passages9 one ofsaid passages being blind and provided with a plurality of outlets and the other oi said `passages having a single outlet, and means exteriorly of' said receptacle for conveying the contents thereof to thatl passage havingl the single outlet, said means servingfunetionally as a' handle orceptacle grip for Said le" 2. A 'trick drinking nlug, comprising av receptacle, a tubular handle carried thereby of said receptacle, a hollow rim carriedA by 354 and'in communication With the lower partv l the upper edge of said receptacle and havof the passage terminating at one of saidopenings, said handle adjacent'to theupper.

end .thereof having a vent opening in coina blind t munieation with the interior of saidtubular f handle7 and the walls of said receptacle ad jacent to said rim having openings formed therein.
