HANS HIELLAND AND FRANTZ MATZOW, OF HOUSTON, TEXAS.
APPARATUS FOR STAMPING ENVELOPES.
SPECIFICATION forming part of Letters Patent No. 411,593, dated September 24,1889.
Application filed February 28, 1888, Serial No, 265,627. (No model,)To all whonm it 7iay concern:
Be it known that we, HANS IIELLAND and
FRANTZ MATZOW, of Houston, in the county of
Harris and State of Texas, have invented a
new and Improved Apparatus for Stamping
Envelopes, &c., of which the following is a
full, clear, and exact description.
Our invention relates to an apparatus for
stamping envelopes, &c., and has for its ob-
ject to provide a means whereby with one mo-
tion a stamp will be supplied from the appa-
ratus, moistened, and placed in position upon
a letter, wrapper, or parcel adapted to receive
it, and wherein a number of stamps may be
consecutively placed when and as desired.
The invention consists in the construction
and combination of the several parts, as will
be hereinafter fully set forth, and pointed
out in the claims.
Reference is to be had to the accompanying
drawings, forming a partof this specification,
in which similar figures of reference indicate
corresponding parts in all the views.
Figure 1 is a perspective view of the de-
vice. Fig. 2 is a section on line x x of Fig. 3.
Fig. 3 is a section on line y y of Fig. 2. Fig.
4 is a horizontal section. Fig. 5 is a section
on line w w of Fig. 4; and Figs. 6, 7, 8, and
9 are detail views.
In carrying out the invention a substan-
tially rectangular box is provided, having
preferably a detachable glass lid 10, for pur-
poses of observation and supply. The box is
further provided with a vertical partition 11
extending from the rear to within ashortdis-
tance of the front, whereby a large chamber
12 is obtained and a small chamber 13, the
chamber 12 being provided with a false bot-
tom 14, opening immediately inside the front
wall. To the rear of the chamber 13 abracket
is formed, in which one member of an angle-
arm 15 is pivoted. The short arm of the lever
extending in front of the box is attached to
a perpendicular handle 16, carrying at its ex-
tremity a horizontal affixing plate or pad 17,
having the under surface preferably covered
with an elastic material-such as rubber-
the function of the plate being to press the
stamp upon the paper. The arm is held nor-
mally in an elevated position at the front by
a spring A, inserted at the pivotal point inany approved manner. In order that the box
may not tilt forward when the handle 16 is
forced down, I provide two forwardly-project-
ing prism-shaped steadying rods or arms 10". 55
SThe affixing plate or pad passes down be-
tween said arms in affixing a stamp, and the
inclines serve as guides for said plate. Within
the chamber 12, to the rear, a drum 18 is piv-
oted parallel with the front, adapted to carry 60o
the stamps, which are pasted together at the
ends or sides, or otherwise made up in long
strips, and in front of the stamp-roller two
engaging friction-rollers 19 and 20 are jour-
naled, the upper roller being the largest 65
and the lower smaller roller turning in a
recess or depression produced in the false
bottom 14, the stamps passing from the car-
rying-roller between the friction guide-roll-
ers. The drums may be turned at pleas- 70
ure by means of buttons 21, attached to
their axles upon the outside of the box.
The axle of the larger guide-roller 19 is ex-
tended through the partition 11 into the
outer wall, and upon this extension in the 75
chamber 13 a pinion 22 is keyed and a bal-
ance-rod 23 is loosely mounted, projecting
slightly to the rear and quite a distance for-
ward, which forward extension is pivotally
united by a connecting-rod 24 with an angu- 80
lar feed-bar 25, located in the chamber 26,
formed by the false bottom 14, one member of
which feed-bar is pivoted to the wall of said
chamber, and the other member, which con-
sists of spaced parallel and apertured strips 85
27, being adapted to lie normally in a hori-
zontal position parallel with the front and in
alignment with the front opening in the said
false bottom, as best shown in Fig. 2.
The chamber 26 is adapted to contain 90
water supplied by a funnel 28, leading thereto
and located in one corner of the chamber 12,
as illustrated in Fig. 4. A plug 29 is screwed
in one wall of the water-chamber, which is re-
moved in filling, as when more than sufficient. 95
water is introduced the aperture acts as an
overflow. Within the water-chamber a sponge
30 is also placed, partially filling the same,
which sponge, as illustrated in Fig. 9, is pro-
vided with a neck 31 and a vertical projection ioo
32 from said neck, the latter being adapted for
location between the spaced perforated meem-
