Improvements in and relating to Sample Cases.
I, WILLIAM WESLEY PAYNTAR, a Citizen of the United States, residing at No. 75
North Lazelle Street, in the City of Columbus, County of Franklin and State of Ohio,
one of the United States of America, Manufacturer of Canvas and Leather Goods, do
hereby declare the nature of this invention, and in what manner the same is to
5 be performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to the improvement of telescoping cases of that class com-
monly used by commercial travellers for carrying samples of goods, and it has
particular relation to means for locking together the two sections of the case.
The objects of my invention are to provide sample cases of the above class with a
catch or
focking attachment of such construction as to cause the automatic locking
together of the two sections of the case when the same are telescoped one within the
other; to construct and attach said locking device in a simple and inexpensive manner,
and to so attach said device as to render it invisible when the case is closed.
These objects I accomplish in the manner illustrated in the accompanying drawings,
in which-
Figure 1 is a perspective view of a sample case showing the general dotted outline
of my improved lock or catch.
Figure 2 is an inner face view of the locking mechanism showing one of the cover
plates removed therefrom and the position of parts when the case is locked.
Figure 3 is an enlarged section taken on line, x, of Figure 1.
Figure 4 is a face view of one of the locking mechanism cover plates showing in
dotted lines the position of parts when the case is unlocked.
Figure 5 is an edge view taken at right angles with Figure 4.
Figure 6 is a detail face view of one of the catch plates of the lower section,
and
Figure 7 is an end view of the same.
Similar letters refer to similar parts throughout the several views.
a, al, represent, respectively the upper and lower case sections of an ordinary
sample case, the upper section being designed to fit snugly over the lower section in
the usual manner.
b, b, represent two vertically parallel rack-bars supported apart as hereinafter
described. The outer edges of these bars are toothed as shown throughout their
length and each bar has projecting inwardly from each of its extremities, a
inger, c. The ends of the upper fingers, c, are turned downward while the
ends of the lower and vertically opposite fingers are turned upward as shown.
The bars, b, are supported against the face of a metallic cover plate, d, the
ingers, c, bearing loosely against the inwardly bent upper and lower ends of said
late.
A second cover plate, d, covers and forms a bearing for the opposite side of the
ars, 6, and intervening parts hereinafter specified.
The upper
le
e, e, represent the two upper sections of two sectional operating arms.
nds of these sections are made to engage respectively with the down-turned ends of
upper bar fingers, c, from which they extend downward to points opposite the
ntre of the height of the rack bars and terminate in beveled ends as shown. e, e',
present the lower sections of said operating bars and form as shown, downward
ntinuations of the upper sections, e. The lower ends of the lower bar sections, e,
e duplicates in form of the upper sections, their lower ends engaging with the rear
es of the upturned ends of the lower fingers, c. The upper ends of the sections, e¹

page_text: are beveled to correspond with the beveled ends of the sections, e, the beveled portions
of both sections being made to meet and overlap, as shown.
The upper bar sections, e, e, are provided at about the centre of their height with
inwardly projecting and overlapping pivot lugs, e², while similar lugs are similarly
formed on the lower sections, e."
These lugs are pivotally connected by pins or rivets, e³, as hereinafter more fully
described.
Between the central portions of the operating bars opposite the connections of their
beveled ends, is an oblong tumbler or bar operating block, g, the lateral sides of which,
when the case is locked, bear, as shown in Figure 2 of the drawing, against the inner
sides of the operating bars. This tumbler has a projection on one side which is
pivotally supported, as shown, within the case cover plate, d, and has projecting from
the opposite side, a neck, g', which projects outwardly through the cover plate, (, and
has formed in its outer end a suitable keyway or socket, g.
Bearing against the outer sides of the operating arm sections, opposite each of the
overlapping points, is the central portion of a bowed spring strip, h, the extremities
of which bear against the inner edges of the rack bars, b.
The parts having been placed together as above described, and the cover plate, d',
being placed against the uncovered side of the locking mechanism, the device is
secured against the inner face of the end of the upper section of the sample case in a
vertical position, as shown in dotted lines in Figure 1 of the drawing.
The pins or rivets, es, heretofore mentioned, are made to pass through the upper
case section and thence through the cover plate, d', through the operating arm
lugs, e², and secured at their inner ends by riveting or otherwise to the inner cover
plate, d. The pins, e³, passing loosely through the lugs, e, thus serve both to connect
the locking mechanism and to pivotally connect the arm sections e, and e¹, heretofore
described.
Secured to the outer face of the lower case section, a', near the upper edge thereof
are two separated rack catch plates, i, the teeth of said plates are formed on their
inner vertical edges, as hereinafter described, and are adapted to interlock with the
teeth of the rack bars, b.
As shown in the drawings, the neck, g', of the tumbler, g, projects through an
opening formed in the upper case section.
Each end of the upper case section being provided as shown, with the herein
described locking mechanism and each end of the lower case section being provided
with the catch plates, i, and the tumbler, A, being in the position shown in Figure 2 of
the drawing, the operation of my locking mechanism is as follows:-
The upper section, a, being dropped in the usual manner over the lower section, a¹,
the spring actuated rack bars, b, will pass between and come into engagement with
the latch plates, i. The horizontal upper sides of the teeth of the rack bars thus
being brought into engagement with the horizontal under sides of the catch plate
teeth, it will be seen that the upper case section will be locked against raising or
separation from the lower case section.
The separation may, however, be accomplished when necessary, by inserting a
key, 3, into the key way of the projecting neck of the tumbler, g, and turning said
tumbler at right angles with its former position, which, owing to its oblong form will
result in such pressure upon the operating pieces, e, e¹, as to force toward each other
the outer ends of said operating arms. This movement of the operating arins through
their engagement with the fingers c, will result in the inward movement of the rack
bars, b, their engagement with the catch plates, i, and the compression of the spring, h,
as shown in dotted lines in Fig. 4 of the drawing. The upper case section may then
readily be removed.
From the construction herein shown and described it will be readily seen that the
two sections may be completely or partially closed together and locked at the desired
point.
It will also be seen that the locking parts herein shown and described are so located
as to prevent their being seen from the outer side of the case when two sections are

page_text: closed or partially closed together, and that they may readily he attached to the
ordinary form of telescoping sample cases without injury to the case.
It will be observed that the use of straps usually employed to bind the two sections
of the case is obviated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is :-
1. In a telescoping sample case the combination with the upper case section, rack
bars, b, located between suitable face cover plates and supported upon the inner
surface of the ends of the upper case section, of the lower case section, a', toothed
catch plates, i, secured thereto and adapted to engage with the teeth of the rack bars, b,
when said case sections are telescoped together, substantially as and for the purpose
specified.
2. In a sample case, the combination with the upper case section, and locking
mechanism connected with the inner surface of the ends thereof consisting of the rack
bars, b, intervening pivoted operating bars engaging with said rack bars, spring
strips bearing between the rack and operating bars, and a key tumbler having a
keyway and adapted to move inward, the rack bars as described of the lower case
section, a', and toothed catch plates, i, secured to the ends thereof and adapted to
engage the rack bars, b, substantially as and for the purpose specified.
Dated this 11th day of November 1890.
