BACTERIA PLATE CABINET Filed June 28, 1957 4 sheets-sheet 4 Inventor A iiorn eys Patented July 19, 1938 UNITED STATES PATENT OFFICE 3 Claims.
This invention appertains to new and useful improvements in means for preparing specimens of bacteria .and storing the same safely until ready for laboratory observation.
Another important object of the invention is to provide a cabinet structure for facilitating the taking of bacteria specimens wherein means is provided whereby the specimens can be properly identified as they are taken.
Still another important object of the invention is to provide an apparatus of the character stated which is simple in construction and not susceptible to the ready development of defects.
These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:
' Figure 1 represents a top plan view of the cabinet.
Figure 2 is a front elevational view.
1 Figure 3 is a longitudinal vertical sectional view.
Figure 4 is a cross sectional view on the line 4-4 of Figure 1. r
Figure 5 is a perspective view fragmentarily showing the guide plate.
Figure 6 is a fragmentary perspective view of one of the specimen glasses.
Figure 7 is a perspective-view of one of the slides.
Figure 8 is a perspective view of a dipping loop.
Referring to the drawings wherein like numerals designate like parts, it can be seen that the cabinet consists of an elongated structure including the front wall 5, end walls 6-! and back wall8.
The cabinet also includes the bottom wall 6 from which rises the partition I6 defining the compartments |l-l2. A second partition I3 extends upwardly from the bottom 9 and terminates below the boiler generally referred to by muneral l4. Extending from the upper end of the partition l3 to the end wall 6 is the horizontal wall l4 which forms a continuing chamber l5 for the chamber l2. v I
A substantial distance below the wall I4 is another horizontal wall l6 extending from the partition l3 to the end wall 6, thus defining a compartment i I. Secured to the bottom side of the wall 14 and the top side of the wall I6 are the corrugated strips l6 which serve to hold the specimen glasses i3 in the manner substantially shown in Figure 3.
The front wall 5 of the cabinet is provided with three openings, one for each of the. compartments l I, I2 and I1 and these openings are closed by the doors 20, 2| and 22, respectively, hingedly connected to the front wall 6.
The top of the compartment II has an opening 23 therein which is normally closed by the closure 24 hingedly secured as at 25 to the top of the compartment II.
In the compartment II is the alcohol lamp 26,
while in the compartment i2 is the alcohol lamp- 21. By lifting the cover 24, the loop 23 can be heated over the lamp 26. This type of loop 23 has the shank 29 and the handle 30 and is ed for picking up. for instance, milk to be depo ted on the smear plates 3l-32 resting upon the boiler l4.
The boiler consists of the box-like structure made up of the bottom wall a, the end walls I) and the side walls 0, the top wall e is provided with a rectangular-shaped opening 33 therein and one end wall D is provided with a-horizontal slot through which the elongated shutter 34 can be disposed. Numeral 35 represents a depending stop on the top wall e at one end of the opening 33.
.As is shown in Figure 5, the top surface of the shutter 34 is laid off in rows of squares 36. The rows are arranged in groups of two and over each group can be disposed one of the smear plates 3| and 32. These specimen plates are of conventional design each provided with a marginal edge portion 31.
Guideways 33 are formed on one end of the top plate e of the boiler, one for each of the rows of squares 36 and through these guides 33 are slidable the channeled covers 39 each provided with an engageable upstanding lug 40 at one end thereof.
These slides 39 can be moved in the direction of the guides 33 to uncover the squares 36 visible through the specimen plates 3l-32 and then as the specimens are placed on the smear plates 3|, the slides are pulled over the plates to shield the specimens.
- Water is placed in the boiler l4 and is heated placed in the rack compartment I'l.
Keepers 4l4| are provided on the front wall 5. for receiving the L-shaped bracket 42 of the shelf 43, this shelf serving as a leaning rest for the attendant.
porting thermometer 44 in upright position.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.'
Having described the invention what is claimed as new is:
1. A cabinet structure 01' the character described comprising a box-like structure having a vertical partition dividing the interior of the box-like structure into a specimen plate racking chamber and a heating unit chamber, and a boiler disposed over the said heating unit chamber, a slide over the said boiler, and rows of marks of equi-distant spaced relation on the said slide.
2. A cabinet structure of the character described comprising a box-like structure having a vertical partition dividing the interior of the boxlike structure into a specimen plate racking chamber and a heating unit chamber, and a boiler disposed over the said heating unit chamber, a slide over the said boiler, and rows 01 marks of equi-distant spaced relation on the said slide, and slide members mounted on the cabinet one over each row of marks on the said slide.
3. A cabinet structure of the character described comprising a box-like structure having a vertical partition dividing the interior of the boxlike structure into a specimen plate racking chamber and a heating unit chamber, and a boiler disposed over the said heating unit chamber, a slide over the said boiler, and rows of marks of equi-distant spaced relation on the said slide, and slide members mounted on the cabinet one over each row of marks on the said slides, and guides for the slide members, said slide members being operative to uncover the marks of the firstmentioned slide.
