Refiled for abandoned application Serial No. 746,106, September 29, 1934. This application July 22, 1935, Serial No. 32,497 V V V 2 Claims.

This invention relates to a dispensing device and relates more particularly to a device for dispensing microscopic slides, dental film packages, etc. A general object of the present invention is to provide a simple, practical and efiective device for' protectively holding and dispensing microscopic slides, dental film packages and like articles. I

It is highly important to'maintain the glass slides employed in microscopes clean and free of dust and finger prints. It is also desirable to have the microscopic slides conveniently accessible for immediate use. Other articles, such as dental film packages, must be protected in a like manner and must be easy of immediate access.

Another object of this invention is to provide a device that is adapted to hold and fully protect microscopic slides and the like against dust and other foreign matter, and that is readily and conveniently operable to dispense the individual slides or articles one at a time.

Another object of the invention is to provide a dispensing device of the character mentioned that dispenses the slides or articles in a manner so that the individual slides or articles may be grasped or removed without touching their faces of surfaces with the fingers. Another object of the invention is to provide a dispensing device of the character mentioned that is small and compact so that it may be arranged in a convenient'accessible position and moved from place to place as desired.

Another object of the invention is to provide a 1 dispensing device of the character mentioned in which a multiplicity of microscopic slides or like articles may be arranged in a substantially dust proof and moisture proof holder and may be individually partially ejected from the holderfor easy and convenient removal therefromby merely depressing a lever arm. Y

' A further object of the invention is to provide a dispensing device of the character mentioned that embodies a minimum number of simple,

' inexpensive parts and that is pleasing and'attractive in appearance.

7 I The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of the invention, throughout 'which description reference is made to the accompanying drawing, in which: 7

This application is filed as a substitute for my application for Letters Patent, Serial No. 746,106, entitled Holder or container and dispenser of microscopic glass slides. 10

The dispensing device provided by this invention includes, generally, a body In having a holder II for a plurality of glass slides S or like objects, an ejector I2 operable to partially eject or project the slides from the holder II, andmeans I3 for operating the ejector.

The body I ii of the dispenser may be formed of stamped or pressed metal or may be in the nature of a die casting, it being a feature of the invention that the body It) is a simple, integral memher. The body It! in being formed of metal or its equivalent, as just described, is capable of being cleansed or sterilized without being injured. The body I9 includes a base I3 adapted to rest on a horizontal support; The base, Is may be rectangular in plan elevation and is preferably comparatively large to prevent tipping. or movement of the device when in use. A post or standard I4 projects upwardly from the base I3 adjacent its rear side or edge. Spaced corner reinforcements I5 may be provided to strengthen the integral connection between the'base I3 and standard I4. r

The holder I I is supported on the standard I4 and projects upwardly and forwardly'froni the upper end of the standard. The configuration and size of the holder II, of course, depends upon the configuration-and size'of the objects to be handled'by the device." The particular holder I'I illustrated in the drawing is designed to hold a stack of typical glass microscopic slides, it being understood that the invention is not to be construed as limited to this construction or this particular use. The holder II 'is integrally joined with the upper end of the standard I4 and the connection may be reinforced by spaced integral corner braces IS. The holder I I is vertically disposed and is substantially rectangular in transverse cross section, having vertical sides and a substantially horizontal bottom wall I1. -The opening It in the holder II is rectangular and is proportioned to hold a'multiplicity of superimposed slides S with suitable slight clearance. V

The inventionprovides a novel protective cover I9for the holder II that facilitates the easy- With the upper'end 2B of the holder.

hinge 2I connects the upper rear corner portion ofthe cover I9 with the upper'end of the holder II so that the cover may be readily swung between the closed position illustrated in the drawing and an open position where the interior of the holder is readily accessible. The cover I9 has an opening 22 which registers with the holder opening I8 when the cover is inits closed position to form a continuation of the holder'openin'g I8. The cover I9 provided with the opening 1122 constitutes a part or continuation of thecholder I I, as it mayconfine and enclose the uppermost slides :S. A rim 23' extends alongthe lower'edge of the cover I9 to overlap andclosely embrace theupper' edge portion ofVthe-holder II to prevent the entrance of dustQetc. 'to the interior of the articles or slides housed in the holder, II are a shelf or ledge 25 mayfproject forwardly imme- 30 r the partially'pro'jected slides, as will become eviholder.

The ;ejector I 2 is operable to move or shift the lowermost slide S forwardly 'toproj ectit through the opening '24 to have a portionaccessible for engagement by the user. 'A ridge or flange 26 extends along the under :side' of the bottom wall jI11of the holder I Iand hasa longitudinal channel'jor opening '21 "for carrying the ejector I2. 7 The flange; 123 and ,itsopenin i21 may be rec-.

SlidB'S'fOI use-at It will be noted that the operation of the device and removal of the slide requires the use of only one hand. The spring 4! immediately returns the ejector I2 and the lever L totheir original positions upon the removal of the pressure from the button 33. The'forward portion of the slide S ejected through the opening 24 is entirely exposed so that its opposite edge portions may be easily grasped between a thumb and finger without contacting either the upper or the lower surfaces of the slide. Thus the slides S may be individually withdrawn from the device as required without marking them with finger prints, the fingers touching only the edges of the slide. The dispensing device of the present invention is easy and convenient to use and effectively protects the slides or other articles.

Having described only a typical preferred form and application of my invention I do not wish to be limited or restricted to the specific details set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art or may fall within the scope of the following claims;
