To all whom it may concern:

Be it known that we, FR D. F. TAPLEY, of

.Lynn, in the county of Essex, and CYRUS H. PORTER, of East Stoughton, in the county of Norfolk, and State of Massachusetts, have in vented a new and useful Surfhce-hl'easuring Machine, of which the following, taken in connection with the accompanying drawings, is a specification.

Our invention relatesto a machine for antomatically indicating the superficial area of sides of leather or other thin flat objects having irregular outlines; and it consists, first, in the combination of aweighing mechanism provided with an index-finger and a scale graduated torepresent square feet and fractional parts thereof, and a Jacquard mechanism adapted to be acted upon by the object to-be measured and cause amovement of the indexfinger along the scale in proportion to the size of said object, and thereby indicate upon said scale the area of the object being measured.

Ourinvention further consists in theme, in combination, ofa skeleton or perforated table to receive the object to be measured, a series of weights or pins arranged equidistant from each other and each representinga given fractional part of asquare foot of area, and adapted to be displaced from their normal position by the object to be measured consequent upon a movement of said pins or weights and object toward each other, and a weighing mechanism adapted tobe controlled by and indicate the amount of such displacement.

Our invention further consists'in the use, in combination with a weighing-seale and an index operated-thereby, of a series of weights suspended above the platform of said scale at points equidistant from each other and each representing a given fractional part of a square foot of area, and adapted to be automatically deposited upon the platform of theweighing device, either separately, collectively, or any given numberthereof, according to the area of the object to be measured. 7

Our invention further consists in the use of a skeleton-frame mounted. in a horizontal position upon springs, in combination with a hinged and pivoted plate or follower of about the same PATENT OFFICE.

area, and adapted to be turned upward away from said skeleton-frame to allow the object to be measured to be placed on said frame, and

then to be turned down upon the object rest ingupon the frame and clamp said object between it and the frame and hold it in an extended position while the frame-and plate and the object clamped between them ate all moved bodily downward to effect the registration of the measurement.

It further consists in the use, in combination, of a yielding frame or table, a pair of is placed upon the skeleton frame or. table, and the follower is then brought down upon it and the whole is then pressed downward,

' such of the yielding pins as are covered by the leather or other object to be measured will be depressed and convey the proper indication to the measuring or weighing device, while those pins not covered. by the object to be measured will pass through the holes in the follower and will not be depressed, and therefore will give no indication, substantially on the principle of the jacquard;

It further consists in, the use, in combination,-of a yielding skeleton frame or table, a series of yielding pins arranged equidistant from each other and each representing agiven area of surface, and provided with a weight so attached thereto that it will move downward with said pin till arrested by coming in contact with the platform of the weighingdevice, and then allow the pin to continue its downward motion, ahinged follower-provided with a series-of holes or openings corresponding in number and position to the yielding pins, and a weighing device provided with an index and a graduated scale adapted to'indi- Gate at a glance the measurement of the side -fileather or other object placed between the follower and the yielding table. 2

collar 0/ and the other end resting on the =per surface of the table E.

g F is a skeleton frame or tablcresting upon or secured to the four vertical pins 0 c, which 0 play through bearings in the tables D and E, and are provided with the collars c c andthe spiral springs d d, surrounding said pins between the collars c c and the table E, the tension of which springs tends to force the table u 3 5 ,.F upward till the collars c 0 come in contact with the under side of the table D, when the upper surface of the table F is on aline with or slightly above the upper ends of the pins a a.

G is a platen or follower, provided with a 0 series of holes, 0 0, corresponding in number and position to thepins a a, and pivoted atf to the radius-links g g, which, in their turn, are pivoted to the upper ends of the standards H'H in such a manner that the followerG 5 may be swung upward away from thetable F,

to enable the operator to place the article to be measured upon the table F.

.I is a handle by which the follower G is operated. J J are a series of weights attached 0 by a flexible or sliding connection one to the lower end of each of the pins a a in such a manner that when said pins stand in their normal position the bottoms of said weightsshall be a short distance above the upper surface of the platform K of a weighing mechanism.

The platform K is pivoted at h to the'short 'arm of the beam-frame L, and held in a horizontal position by the radius-link M, pivoted att' to the stud N, projecting downward from the under side of said platform. The long arm of the beam-frame L is connected by the link j to the movable end of the lever 0, se-

By this downward movement ing through the holes ea in the follower by the leather or other article being measured will E, compressing the springs 11 b,iand carrying with them the weights J J, till said weights come in contact with and rest upon the platform K,when, by virtue of the flexible or slidingiconnection of said weights with the pins a a, their weight is deposited upon the platform and removed from the pins or a. The depositing of the weights J J causes the platform K and the short arm of the beam-frame L to be depressed, and the ion g arm of the beam frame L is correspondingly raised, causing the indextinger- R to be moved about the axis of the rocker-shaft P and alon g the graduated scale a distance proportioned to the number of weights deposited on the platform K. When the pressure'is removed from the handle I all the parts immediately assume their normal condition again, when the follower is raised to a perpendicular position, when the skin or on the frame F,and the operations "are repeated.

The scale S should he graduated to indicate square feet and fractional parts thereof, and to correspond to the number of the pins 1 a and the weights J J. The weights J J may be attached to the pins a a by means of the chains 1 l, as shown, or by a cord or other flexible connection; or the weight J- may be made annular, and the pin a may move through the weight and through a hole formedfor the purpose inthe platform K when the weight has been deposited on the platform K, said weight being taken up again when the rod a rises oy the collar m on the lower end of the rod 0, as shown in the modification at Fig. 6.

Another modification of the mode of hangiug the weight is shown in Fig. 7, where the pin a is made hollow, the upper portion being chambered out larger than the lower-portion, and the weight J having screwed into its upper end the stem it, provided at its upper end with a head, a, which rests on the shoulder l in the hollow pin a, when said pins are in their The operation of our invention is as follows:

on the leather or other object to be measured,

' press the follower G andthe frame or table F, tween them, downward till the frame F rests of the follower G and frame F all of the pins a athat are covered and prevented from passbe moved-downward through the tables D and side of leatlrer is removed and another placed normal position, and when depressed the hollow sleeve-like pin 01. moves along the stem it after the weight is deposited upon the platform K.

The tables D, E, and F and the platen or follower G- should be made of suflicient area to receive the largest side of leather or other article that it is desired to measure, and there should be a pin, a, and weight J to every q'ua r' ter, eighth, or sixteenth of a square foot area contained in said tables, according to the degree of accuracy desired in the measurement.
