UNITE@ STATE@ PATENT @FFIQE JOHN H. BARNARD, OF BROOKLYN, NEW YORK.
SECTIONAL MOUNTING OF CHARTS, &c.
Application led September 10, 1913.
To all whom t may concern:
Be it known that I, JOHN Il. BARNARD, a citizen of the United States, and a resident of the borough of Brooklyn, city and State of New York, have invented certain new and useful Improvements in Sectional Mounting` of Charts, &c., of which the following is a specification.
rIhis invention relates to sectional mountings for charts, maps, drawings and the like, b v the use of which charts, etc., may be more conveniently stored and can be readily combined or put together for use.
In order that the details of a chart or drawing may be studied or measured it should be kept ilat, but under many conditions this is di'tlicult. Often the area to be studied forms the margin of one drawing and the adjoining edge of another, both of which may be large in comparison to the portion of interest to be studied. Frequently, also, charts or drawings must be studied in contracted spaces and sometimes possibly in winds.
In the improved form of mountings the diliiculties heretofore encountered are entirely overcome or greatly minimized.
In one embodiment of the invention there is provided a series of interlocking blocks of similar outline and of only sutlicient thickness for the conditions under which the drawings are to be used. Preferably the blocks should be made of material which combines suflicient strength and lightness and neither warps nor absorbs moisture. For most purposes hard rubber is suitable, but there is a great variety of materials which will fulfil all the requirements and I do not limit myself to any particular material.
The individual blocks may be placed and retained -in proper relative position by interlocking one block to another, each block locking upon a slab carrying all the blocks,
or by interlocking' with each other and with the slab. The first means requires thicker and stronger blocks to afford the necessary mechanical strength, and consequently more room is required for the storage thereof. Of the two ways that of locking with each other and with the board seems best for the reason that in many instances more blocks may be needed at once than a board adapted to the usual number of blocks can carry and in such case the eXtra blocks may be placed and retained in position. on any Specification of Letters'atent.

Serial No. 789,018.
suitable flat surface. As each means, however, may be best adapted to special purposes, there is shown in the drawing examples of each, but I do not limit myself to either one of these means or to any particular means.
rIhe invention will be more fully understood from the following description taken in connection with the accompanying drawing, in which:
Figure l represents a plan view of one type of the invention with two blocks removed.
F-ig. 2 is an edge view of the same.
Fig. 3 is a sectional view on line 3 of Fig. l on an enlarged scale.
Fig. s is a perspective of the under side of one of the blocks used in Fig. l.
Fig. 5 is a sectional view of a modification.
Fig, 6 is a perspective view of one of the locking means for securing together the adjacent sections of blocks shown in Fig. 5.
0n the drawing the part marked 20 represents a board which is provided with a series of studs 2l with the heads 22 set above the upper surface of said board. On the edge of the board is provided a series of longitudinal adjustable clamps 23 which are mounted against a. plate 24 having slots 25 therein, through which project the set bolt nuts 26 to secure the clamp in position. 30 represents the blocks7 the under sides of which are provided with the Crossed undercut grooves 31, which receive the heads of the studs 21 when the blocks are in place. Two of the edges of each of the blocks are provided with grooves 32 and the other edges are provided with the tongues 33.
I/Vhen the blocks are in place on the board, as shown, said tongues 33 fit into the grooves 32 of the adjacent blocks and hold the blocks in the same plane. rIhe undercut grooves 31 permit the blocks to be slid or moved over the studs 2l both longitudinally and transversely of the hoard. The clamps are arranged so that they take up against the outer edges of the marginal blocks and hold them in proper position.
40 represents a part of a map or drawing on the upper face of the block, which map or drawing may be on a sheet of paper and pasted on the block. rlhe arrangement is lsuch that when the blocks are in proper place 0n the board the adjacent edges of the map or drawing will register.
In Fig. 5 there is shown a construction in which the board on which the blocks are to be mounted is dispensed with and the blocks are secured together edge to edge. In this construction it is necessary to form the blocks much thicker than in the previous construction. l In this construction the blocks are marked 50 and the under side of each block is provided with the recesses 51. Projecting into each recess is a keeper 52. 55 is the locking` means which consist of two plugs 56 to be inserted in the recesses 5l. The plugs are joined 'together by the bar 53 and the inner surface of each plug is provided with a spring catch 57 which snaps over the keeper 52 and locks together as shown in Fig. 5.
Various other modifications may be used without departing from the spirit and scope of the invention.
The device as constructed according 'to Figs. l, Q and 3 of the drawing is operated as follows: Suppose that part of the chart represented by the block marked Z) is being used and some part of, the chart shown above Zn and c is shortly'to be used; in this case the blocks a and Z are removed by loosening and moving the slides 23, and then the blocks Z) and e are moved downwardly so that the block c is at the bottom of the board, and Z) is removed to Where e is at the present time; then both ZJ and e are moved to the left of the board.
rilhe block i can be removed and c and f can be moved toward the bottom of the board and then moved to the left so that additional blocks showing the chart above b and c and to the right of c and j can be placed on the board.
Having now described my invention what Iv claim as new and desire to secure by Letters Patent, is:
l. A chart comprising a plurality of sections each of the same area and inter-engaging means on the edges of the sections to lock the sections together and position their edges in alinement.
2. A sectional mounting for charts, drawings and so forth, consisting of a series of sections each carrying a part of the chart or drawing, and a support, the sections being provided with means for interlocking them with each other and with the support so that consecutive sections will produce a combined area made from the several sections.
3. A chart comprising a plurality of sections each of the same area and inter-engaging means on the edges of the sections to lock the sections together and position their edges m almement, a support for each .of said sections and means for securing each section to said support.
4i. A chart comprising a plurality of sections each of the same area and dove-tail engaging means on the edges of the sections to lock the sections together and position their edges in alinement.
5. A sectional mounting for charts, drawings and so forth, consisting of a series of blocks each carrying a part of the chart, and aslab, the blocks being provided with means for interlocking themwith each other and with the slab, so that, consecutive sections of a print or drawing, will produce a combined area. made from each of several charts or drawings.
6. A sectional mounting for charts, drawings and so forth, consisting of a series of blocks each carrying a part of the chart, and a slab, the blocks being provided with means for interlocking them with each other and with the slab, so that consecutive sections of a print or drawing may be combined to produce a particular area, and which area may be progressively extended in any one or in any adjacent two of the four directions by corresponding subtractions in the opposite direction or directions.
7. A sectional mounting for charts, drawings or the like, consisting of a slabI and a series of blocks, each of the blocks carrying` part of a chart, said blocks being provided with tongue and groove connections on the edges thereof, undercut grooves transversely of each 1clock, a series of studs carried by said slab to coperate with said grooves, a series of transversely movable clamps mounted on said slab, said clamps provided with means to engage said tongues or grooves, and means for fastening the clamps in position as and for the purpose set forth.
8. A chart comprising a plurality of sec tions each of the same area and inter-engaging means on the adjacent edges of the sections consisting respectively of tongues and grooves fashioned to fit one within the other to hold the sections together and position their edges in alinement.
In witness whereof I have hereunto set my hand in the borough of Manhattan, city and State of New York, this 28th' day of August 1913.
