TYPEWRITING MACHINE CARRYING CASE Original Filed April 24 1924 Awe/var.

Patented July 5, 1932 UNITED STATES PATENT OFFICE ALFRED G. F KUROWSKI, F BROOKLYN, NEW YORK, ASSIGNOR T0 UNDERWOOD EL- LIOTT FISHER COMPANY, OF NEW YORK, N. Y., A. CORPORATION OF DELAWARE TYIPEWRITING MACHINE CARRYING CASE Original application filed April 24, 1924, Serial No. 708,633. Divided and this application filed August 6,

i 1927. Serial No. 211,078.

This invention relates to improvements in typewriting machine carrying cases, and particularly to types commonly known as portables, in which the machine is normally en- 7 6 closed within a case adapted to be conveniently carried by hand.

One of the objects of the invention is .to provide a two-part, separable case in which 6 the cover element maybe positively and safe- .1y secured to the base'in such manner as to efl'iciently protect the machine from intrusion, damage, dust or'moisture, under ordinary conditions of transit or storage, or to permit the ready removal of the cover to allow authorized use of the machine, either as aflixed to the base element of the case or removed operably intact therefrom.

Another purpose is. to produce a carrying case base provided with means which operate effectually in minimizing, reducing and preventing the transmission of sound, incurred by operation of the machine, absorbing aircarried sound vibrations to a marked degree. A further feature is the construction of a carrying case having its top, two sides and base-plate formed of sheet-metal for obtaining a casing of minimum height and width with respect to the typewriting machine.

A further aim is in the provision of an unusually light, strong'and compact carrying case of pleasing design, readily portable and having a base-wall suited as a support upon which the machine may be conveniently operated, while acting as a silencer for any sound produced. r

This application is a division of my application, Serial No. 708,633, filed April 24, 1924. r Other features and advantages will here- 'inafter appear. i

' warranted intrusion.

Figure 3 is a fragmentary sectional view taken on line 33 of Figure 2.

Figure 4 is a similar view taken on line l4: of Figure 2.

The portable typewriter, shown in broken lines in Figure l and designated generallyby the numeral 10, is standard in all respects and constitutes a complete commercial entity.

The carrying case is composed of a front end plate or member 15, preferably made of well-seasoned wood, as is also the rear end plate or member 16. An integral piece of sheet-metal is formed to present side walls 17 and. a cover 18, inclined downwardly at the front 19 and having inwardly-curved edges 18 engaged in corresponding recesses in the upper and end edges of theplates l5 and 16, to which the cover-plate is rigidly secured, and the entire outer surface of the casing is insheathed in leather.

A strap handle 20 is provided on the front end plate 15 forconvenience in carrying, and

a lock, generally designated by the numeral 21, is furnished to provide security from un- Fixed near each of the four corners of the bottom plate are button-headed nails 22 or the like to protect the leather-covered surface of the case, when resting on its bottom or lower end, the foregoing elements constituting the cover or removable portion of the case.

The base-portion is composed ofa wooden frame 23 formed from quarter-roundmolding with mitered joints, freely receivable within the lower portion of the cover.

A sheet-metal plate 24: is secured to the flat lower surface of the frame 23, and is provided on its lower exposed side with a leather covering, from which extend four cushioning elements, as the rubber feet 25, held in rigid engagement by cement or like adhesive.

The rear, member of the frame 23 contains recesses 26 adjacent its ends, these recesses having metallic-linings 27 suited to be e11- gaged by a pair of hooks 28, fixed to the inner surface of the rear end plate 16, and adapted. to interlock with the linings to removably engage the rear end of the base within the cover, as best shown in Figure 3.

Set midway in the length of the front member of the frame 23 is a button-headed stud 29 projecting to interlock with a spring-latch incorporated in the lock 21, see Figure 1, thus co-operating with the hooks 28 at the opposite end to securely lock the cover to the base, constituting a single carrying unit.

The typewriting machine 10, as indicated by broken lines in Figure 1, as composed of a pair of east side frames 11 having extending base-pads 12, serving as feet during assembly of the machine, the same being drilled and tapped, to receive detachable rubber feet The typewriter-frame sides 11 terminate,

'as shown in Figure 1, at the inner row of the key-levers to define a machine-base area, but

affording no protection to the bank of keys,

as it would obviously add greatly to the weightof the frame andcasing if it were continued-around the keyboard in the usual manner.

The frame 11 is enclosed by a highly-polishedouter frame or silencing pocket shaped by power press methods from a single piece of sheet-metal to produce opposed side walls 30 and rear wall 31, all of which have inwardly-curved or rounded-over upper edges 30 and 31' resentin a smooth and a reeporous felt 39, the same acting to absorb soundemanations, which would otherwise be transmitted 'to the supporting base.

The upper surfaces ofthe ledge 33, crossbar34 andentire base-plate35 are similarly covered with a like but thinner felt fabric 40, and thus, when-the machine is set in the en- "closing frame, its feet rest upon the lined surface 40.

In order to secure the feet 41 to the base of the carrying case and prevent any relative shifting movement, flanged metallic rings 45 are fixedin appropriate locations in the base, these rings being receptive of the feet and which are positively but removably held therein by the following means.

' Extending oppositely outward from the sides-3O of the outer frame are rigid studs 46 having rounded outer ends, these studs being suited to engage in openings formed through latch-elements 47, pivotally supported in brackets 48, fixed on the base-plate 24, as bestseen in- Figure 4.

The outer ends of the latches are curved to provide finger-holds and their inner ends project beyond their pivotal points to engage the free end of a spring-detent 49 riveted to the plate 24 and extending below the pivot in the bracket 48, the detent being so shaped and arranged as to hold the latch 47 in either a raised, operatively engaging, position or when turned down to clear the studs 46.

These latches are readily accessible when the cover of the carrying case is removed and are operable by hand only, no tools being required to release the machine from the base.

Asa further factor in rendering the machine substantially noiseless, when used upon the base of the carrying case, the base may be provided with a thicklayer of felt v5O on its entire upper surface, the same .preventing transmission of sound.

It will be noted that the two side frames 11 are machine standards to promote the as-' sembly of the parts and establish a machinebase area that does not include the key-board; that the assembled machine is enclosed by a highly-polished outer frame which also includes a forward extension to protectively enclose the keyboard of the machine; that the enclosing outer frame is formed with a floorsection of substantially the same areaas the established base of the machine to enclose the machine on the under side; that the outer crease the base-areaof the machine when .in

use and only eoacts with .the cover when the maehineis not in use or being carried from place to vplace.

. 'It'will also beseen .thatthe carrying case, beingformedwithasheet-metalbaseeplatefor the typewriting .machine and a sheet-metal opposite side wall for the cover, provides a carryingcase having aminimum thickness, materially reducing the thickness of carrying casesin which :the corresponding walls are formed ,of wood or other compositions.

The arrangement permits the sheet-metal walls to be spaceda minimum distance apart, with sockets to receive the feet of the typewriter, so that they will rest directly upon the base. It will be noted that the typewriting machine with its outer frame resting upon the base-plate, provides a chambered pocket between the'bottom of the outer frame of the typewriter and the base-plate into which sounds emitted through the bottom of the outer frame are received. This arrangement permits the positioning of a sound-absorbing padding on the base-plate to further deaden the sounds which enter this chambered pocket. The padding extends over the base-plate between the sockets for thefeet of -the -machine and the flanges or frame-members 23 of the base without necessitating an increase in the space between the two walls.

Variations may be resorted to within the scope of the invention, and portions of they improvements may be used without others.

Having thus described my invention, I claim:

A carrying case for a portable typewriter, comprising a thin, fiat base having all its bottom surface in a single plane, a relatively thick separate strengthening rim attached around the inner. periphery of the base to form a reinforcement therefor, the base bottom having sockets to receive the rubber feet of the typewriting machine, sound absorbing felt covering the interior top of the base bottom and a cover for the case including relatively thick front and rear ends and thinner top and side portions, said top portion having an inclined front portion, said sides and top portion being all in a single piece and fastened to said relativel thicker ends.
