GEORGE INNIS, OF NEWBURY, AND WILLIAM R. WHITMORE, OF NEWBURY- PORT, MASSACHUSETTS.

TYPE-SIFTER;

SPECIFICATION forming part of Letters Patent No. 228,997, dated June 22, 1880.

7 Application filed February 18, 1880.

To all whom at may concern:

Be it known that we,- GEORGE INNIS, of N ewbury, in the county of Essex and State of Massachusetts, and WILLIAM R. WHITMORE, of Newburyport, in the county of Essex and State of Massachusetts, have invented a new and useful Type-Sifter, of which the following is a specification, reference being had to the accompanying drawings. IO Our invention consists inacase having coinpartments corresponding to, and being counterpart or reverse in position to. those in an ordinary typecase, and thus adapted to be employed in combination with the ordinary type-case as a type-sifter.

In the drawings, Figure l is a perspective view of an ordinary type-case having our types fterin position thereon previous to reversing the cases to sift. the dirt from the type.

no Fig. 2 is a plan view of the ordinary case; and Fig. 3, a plan view of our sifter, shown in Fig. 1. Fig. 4 is a vertical section taken on line 1 1, Fig. 1. Fig. 5 is a similar section to Fig. 4, but having the perforated bottom of the sifter next to the ordinary case. Fig. 6 shows a vertical section through our type-sifter.

It is well known that in ordinarytype-cases as heretofore constructed dirt collects, to the great annoyance of type-setters. The bottom of the compartments being close, this dirt is removed with difficulty and with great liability to accidentally change the type from one compartment to another, thus causing great loss of time.

3 5 The purpose of our invention is to obviate these annoyances, and to provide means for readily cleaning the compartments and the type therein.

. We make a case, A, having compartments '22, arranged in amanner to correspond to those,

' b, in an ordinary type-case, B, and having a perforated bottom, 0. When the compartin the sifter A will be reversed in position to those in case B, as Will be readily understood. This case A may be placedon the caseB bottom uppermost, as shown in Fig. 1, and fastened thereto by convenient means, as by the springhasps 0. Then by reversing the two cases the type is caused to pass from the compartments 1) directly to the corresponding compartments a, and the dirt will sift through the perforated bottomO. The case B may then be removed if desired, leavin g'thetype in case A for further 5 5 cleaning or for other purposes.

In the drawings the perforated bottom is shown as of wire-gauze; but any suitable material may be used having perforations of size and number to accomplish the desired result namely, to free the type from'dirt and other foreign matter that will pass through the perforations, while the type is retained.

When wire-gauze or similar material is used we prefer to further support and keep the same in place by means of the strips or under frame-work D, corresponding to and fastened together with the gauze to the frame and partitions of the case, as shown.

We claim as our invention- A case having a perforated bottom and compartments corresponding to and being counterpart or reverse in position to those in an ordinary type-case, and thus adapted to beemployed in combination with said ordinary type- 7 5 case as a typesifter, substantially as hereinbeforeset forth.
