B. GILCHBIST., 0F NEWARK, lNE\V JERSEY, ASSIGNORrTO .THE GILCHBISI COMPANY, 0I NEWARK, JERSEY, A CORPORATION 0F NEW JERSEY.
To all 'whom t may concern Be it known that I, RAYMOND B. (in.- cHRIs'r, a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Mixers, of which the following is a full,
clear, and exact description.
The invention relates to mixers and more particularly to that type which includes a removable strainer cover and a breaking device for fluids, such as an egg drink, which requires a cutting or breaking action in addition to the agitation to effect thorough com-mingling and disintegration of the constituents of the mixture.
One object `of the invention is to provi/.le a mixerv with an improved egg-breaking device which is simple in construction and 'which can be readily cleansed so that it Will be sanitary and which eliciently serves to disinterate and mix the contents of the receptacle.
eretofore, it has been the practice in devices of this character to employ spurs for this purpose, but these devices were unsanitary, because of the difliculty in thoroughly cleansing them.
A further object of the invention is to provide an improved breaking device which consists of a conoidal spiral strip at the top ofthe receptacle and is extended over substantially the entire V,area of the top 'of the receptacle to provide cutting edges of great length, so thatliquid thrown against the mixer top will strike some or other portion of the cutting spiral. form of breaking device is somewhat resilient, so that when ice;y with which the drink is usually mixed, strikes against it, a cushioning eect will be obtained which prevents the spiral from becoming broken'and also prevents the ice, in event of severe shaking,
.from tending to force the cover oftl the body ofthe mixer.
The invention also contemplates forming this spiral of substantially square wire which will have four cutting edges of great length and in which the angular sides are inclined relatively to the axis of the receptacle for efficiency in disintegrating action upon. the liquid.
A further object of the invention is to provide a mixer of improved construction. l
In the drawings: Figure 1 is a vertical Specification of Letters Patent.
A resultant advantage is that thisy section. of a mixer embodying the'invention. Fig. 2 1s a perspective of the breaking device separatedfroni the cover-of the receptacle.
T he mixer comprises a receptacle-body having an' open top, a bottom 4, and a side wall 5. A cover 6 having a flange 7 is adapted to fit snugly around the upper end of the side wall 5 to removably hold the cover on the body. A perforated strainer-plate 8 is fixedly secured inthe cover by spinning the latter around the edge of the plate, as at 9. The cover is extended above the strainerplate, as at 10, to form a spout through which the strained contents of the mixer can be poured and a cup-shaped cap 1l is adapted to it on the top and form a closure therefor during the shaking of the receptacle.
The improved breaker is carried by a central post 12which is provided with a screw'- threaded socket 14 at its upper end adapted to receive a screw 15 which is adapted to extend through one of the holes inthe strainer-plate and is on a thumb-nut 16. The upper end of the post 12 abuts against the lower face of said pla-te so that the post will be rigidly but removably secured to the strainer-plate. The breaker 'consists of a vstrip of wire 17 which is substantially square in cross section and is formed into an inverted substantially conoidal spiral. The lower end of this wire is turned toward lthe post and reduced and extended through the lower end of post 12, as at 18, and riveted thereto so y Patented Oct. 17, 1916. v Application led July 80, 1915. 1SertalNo. 42,766.
disintegrate the contents of the mixer, be-
cause the wire has a number of sharp cut` edges of great length. This device is tin sanltary, because the use of spurs, which are diiiicultl to cleanse, will be avoided, and because substantially all surfaces are accessible for cleansing. v'In practice, it sometimes occurs that the liquid adheres to the 1 of the receptacle.
breaking device. The coils 'of the spiral are separated sufficiently so that all portlons of the w11e can be thoroughly cleansed and wiped, 1f desired.v By employmg a radlal arm or connecting portion 19 between the coil of greatest diameter and the post, the inner surfaces of the wmdlngs are left accessible when the post is removed from late 8.Y Furthermore, when square wire is employed, the spiral has sufficient resiliency to prevent the ice from bending it and from tending to displace the cover from the body By employing an inverted conoidal spiral, the 'ice is prevented from packing against the strainer-plate v restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
Having thus described my inve11tion,what I claim as new and desire to secure by Letters Patent, is:
1. In a mixer, the combination with a receptacle and a removable cover thereon, of a post, means for attaching the post to the cover so it is removable from the receptacle therewith, and a breaker consisting of an inverted conoidal spiral of wire extended around the post. 'l
2. In a mixer, the combination with a receptacle and a removable cover having a strainer fixed therein, of a post, means for attaching the post to and so it will depend from the strainer, and a breaker consisting of a spiral of wire extended around and rigidly secured to the post.
3. In a mixer, the combination with a re- 1 ceptacle, and a removable cover having a strainer fixed therein, of a post, means for removably securing the post to and so it will depend from the strainer, and a breaker consisting of a spiral of wire having both of its ends secured to the post.
et. In a mixer, the combination with a re- I' ceptacle and a removable cover fittingthereon, of a post, means for attaching the post to the cover, and a breaker consisting of a spiral polygonal wire on the post.
In a mixer, the combination with a .receptacle, yand a removable cover thereon, of
,y a .breaker consisting of a spiral of wire substantially square in cross section-,and means for attaching the breaker to the cover.
6. In a nnxer, the combmatlon with a receptacle and a removablecover thereon hav- 7. In a., mixer, the combination with a receptacle, and a. removable cover thereon, of a breaker consisting of a spiralof l'wire substantially square in cross section, the surfaces of the wire being inclined relatively to the axis of the receptacle, andfmeans for .attaching the breaker to the cover.
8. In a mixer, the combination with a receptacle, and a removable cover thereon, of a postattached to and removable with the cover, and a. breaker on the post and consisting of an inverted conoidal spiral of wire, substantially square 1n cross section,
the surfaces of the wire being inclined relatively to the axis ofthe post.
9. In a mixer, the combination with a receptacle and a removable cover thereon, of a post, removably attached to the cover, and
a breaker consisting of an inverted conoidal spiral ofwire having both of its ends extended through and rigidly secured to the post.
10. In a mixer, the combination with a receptacle and a removable cover having a strainer-plate thereon, of a post, means for detachably securing the post to the strainerplate, and a breaker consisting of an inverted conoidal spiral of wire havin both of its ends extended through and rigldly secured to the post.
11. In a mixer, the combination with a re ceptacle, comprising a body and a removable cover thereon, of a post, means for securing the post to the cover so it is removable from the body therewith, and a breaker consisting of a conoidal spiral of wire having both ofits ends reduced and extended l through and riveted to the post.
12. In a mixer, thecombination with a receptacle and a removable cover fitting thereon, the cover having a perforated strainer plate fixed therein, and a removable cap on the top thereof, of a post, means for detachably securing the post to the strainer-plate and a breaker, consisting of an inverted conoidal spiral of wire having its lower end secured to the ,lower end of the "post and having'a radial portion extending from the upper coil inwardly 'to the post, both ends of the spiral being fixed in the post.
