Patented July l, 1930 MILLARD FILLMGRE RAMSEY, ACHILLE, OKLAHOMA CABINET Application led December 10, 1926. Serial No. 153,936.

rlhis invention relates to cabinets especially designed for housing a number of flexible printed sheets or strips for use in computations, an object of the invention being to provide a novel cabinet structure for normally housing these sheets or strips in a manner to permit them to be readily exposed for use, together with means to keep the strips clean so that the indicia thereon may be plainly read.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevation of the invention with one of the calculating sheets or strips 2U partly extended.

Figure 2 is an enlarged verticalsectional view.

Figure 3 is an enlarged longitudinal sectional view showing the manner of mounting the strip carrying rollers.

Figure 4 is an enlarged fragmentary section taken substantially on the line 4-4 of Figure 1 with the strip partly withdrawn.

Figure 5 is a detail perspective view of one of the shaft brackets.

Figure 6 is'an enlarged fragmentary plan view showing a corner of one of the strips.

Referring to the drawings in detail where- D in like characters of reference denote corresponding parts, the invention is shown as comprising a cabinet which is indicated generally at A and which is shown as formed of a base section 10, a top section 11 and an intermediate section 12. These sections are substantially the same in construction, except that the base section is provided with a bottom 13 and the top section is provided with a top or cover 14. The sections are arranged one upon'the other and are hingedly connected along their rear edges as shown at 15 and as they are in communication with one another, the connected sections form a single A cabinet open from the top to the bottom. i Fastening devices in the form of hooks 16 in one direction serve to prevent accidental opening ofthe sections.

' Mounted within the cabinet and supported in brackets 17, is a plurality of stationary shafts 1S. These shafts are round through- 55 out the major portions oftheir lengths, the opposite `ends being square so as to `be received and held within the projections 19 of the brackets 17. As shown in Figure 3 of the drawings, the shafts 1 8 are vertically and 60 horizontallyoftset fora purpose hereinafter apparent.

Mounted upon each ofthe shafts 18 is a plurality of rollers 20 between which are arranged spacing blocks 21'. The rollers are 65 freely rotatable upon the shafts, but rotation is yieldingly resisted by springs 23. One of these springs is provided for each roller so that the rollers may Y Y operate independently of one another.

yfound upon therollers 2O are sheets or strips 21v which are extended outward through s'lots 22 provided in the front face of each ot' the sections of the cabinet. Sel cured to the outer edges ofthe strips are grip- '5 ping bars or handles 24. These bars or handles provide convenient means for pulling the strips outward and further act as 'Stops to limit inward movement of the strips. Itis preferred to make the slots 22 relatively wide 80 and to secure within these slots, strips 25 of felt or other compressible material. This will act to exclude dust from the interior of the cabinet and will further act as a wiper for the strips 21. In addition, they will form a cushion against which the strips 24 engager By reference to Figure 1 it will be seen that each section of the cabinet is equipped with nine strips and consequently with three shafts and nine rollers, except the top section 11, whose uppermost roller and strip 21a extends entirely across the cabinet. The particular arrangement and number of strips 5` employed however is dependent upon the usefor which the device is intended.

In the present application, the device is shown arranged for calculating the number of board feet and price of the same for a 1.00 given number of linear feet of board of a 'ven size. The lengths of the boards are indicated along the upper edge of each of the slots as shown at 26 in Figure 1 of the drawings, while the width and thickness is indicated on the outer edges of the strips 24. On some of the strips 24 it will be seen that a board of only one dimension is given while lllrpon `other strips more than one is given.

or example, one of the strips 24 contains the measurement for boards 2 X 12, 3 X 8 and 4 x 6, all of which equal 24, so that the price of a twelve foot board for either of these sizes would be the same. The strips 21 have their figures arranged in longitudinal and transverse columns, the vertical column to the left and indicated at a contains the number of pieces, while the remaining columns contain the lengths of the board. By reference to the strlp 24 which is shown partly Withdrawn it will be seen that a board 1 X 12 and 10 feet long will contain 10 board feet, while two pieces of board of the saine length will contain 20 board feet. This is found by reading the number to the right of the column a.

The topmost strip 21a contains the cost per board foot, a board selling for two and onehalf cents per board foot would cost twelve and one-half cents. for ve board feet. The calculations are arranged from 1 to 100 pieces of 'lumber and calculations above 100 are in units of 100, for example, 200, 300, 400, etc. In calculating 735 pieces of one dimension the strip would be` pulled outward to 700 and then permitted to move inward until it reaches 35 and the sum of the two would be the` answer. Y This operation is the same with the rice sheet or strip.

' e invention is susceptible of various chan es in its form, proportions and minor da of construction and the right is herein reserved to make such changes as properly fall with the scope of the appended claim.

Having described the invention what is claimed is A cabinet having a slot in one of its walls, a. spring actuated roller within the cabinet, a strip wound upon said roller for passage through the slot, a combined gripping element and stop secured to the outer edge of the stri and extending beyond opposite faces of t e latter to provide convenient means to pull the strip outward and to limit inward movement of said strip, and compressible elements located within the slot and engageable with the opposite faces of the strip to wipe said faces and provide a buffer for the combined gripping element and stop.

In testimony whereof I afiiX my signature.

MILLARD FILLMORE RAMSEY.
