Patented June 26, 19.23.

STATS .onzersrrAn J3. nnnson. or onroeeo, iLLInors.

BooK-oovnn GAUGE.

Application filed Marcli23, 1922. Serial no. 546,033.

To all whom it may concern:

Be. it known that I, CHRISTIAN B. Nnnson, a citizen ,ofthe United States, residing at Chicago, in the county ,of Cook and State of Illinois, have invented certain new and useful Improvements in Book-Cover Gauges, of which the following is a full, clear, and exact description.

y gauges, and particularly to the instrument employed by them to assemble the backs and covers of books.

The objects of my invention are to provide a gauge the parallel members of which can be relative-1y adjusted to accommodate the width of the back of any book; which will not smear the mucilage or cement, and which are provided at one end of each of the parallel members with guards against.

which the top edges of the covers implnge, substantially as hereinafter fully described and as illustrated in the claims.

In the drawings:

Figure 1 is a plan view of my invention showing its application to the back and covers of a book.

Figure 2 is a side view thereof drawn to a larger scale.

Figure 3 is a transverse section of the same taken on dotted line 3, 8, Figure 2.

In the drawings, 5 and 6, represent two corresponding parallel gauge-members consisting of straight metal rules that, stand on edge and have their under edges 7 chamfered from their inner opposing sides to their outer sides so as to reduce the width of the said edges, which latter rest upon the work, as hereinafter fully described.

At their lower ends these gauge-members have corresponding internal tubular arms 8, that project at right angles thereto, and have the straight surfaces of the sides thereof facing the outer straight surfaces of the gauge-members 5 and 6, and have their under edges upon which they rest reduced or tapered upwardly away from the lower portion of their straight surfaced sides as seen in Fig. 2 of the drawings.

These arms are adapted to have the lower edges of the book covers, when the latter are placed next the inner surfaces of the gauge-members, bear against said arms. The lower sides of these arms 8 (which give the gauge-members an L-shape) are slit longitudinally, as at 9, in Figure 2 of the draw lugs invention relates to bookbinders are the means employed to connect and to permit of the adjustment of the gauge-mem- .10, located preferably, nearer their free ends,

upon a transverse gauge-bar, 11, which i Theselslits extend to the bores, of the arms, 5

lattertis of a suflicient length and. diameterto be inserted longitudinally through the bores of said arms 8, and clamped therein. The gauge-barll and a transverse rod 12,

bers toward and ,from each other. The

transverse rod 12, has one end secured in any suitable manner in one gauge-member 5,nea r the end thereof opposite its arm 8,

and. said rod extends transversely through a suitable openingin the opposite gaugemember, 6, preferably .as far as the adjacent end of the gauge-bar-ll, and a headed setscrew 18, is tapped longitudinally into the end of said member, 6, into the opening through which rod 12 passes and bites into the same and holds the gauge-members in their adjusted positions.

In operation the back A of the book is laid flat, and the gauge-members are placed longitudinally upon the back, parallel with but removed back from the longitudinal edges of the same, so as to leave margins of equal width, upon which mucilage is placed. The gauge-members are then secured in this position by the gauge-bar 11 and set-screws 10 and rod 12 and set-screw 13. When the parts have been adjusted and set the lower edges of the covers B, B, of the book are positioned to bear against the arms 8. and are properly placed and assembled with reference to the back so that they over-lap the mucilaged margins of the back, to which they are then cemented. The back and covers are then removed and the operation repeated.

If desired the relative position of the gauge-members can be reversed and the arms 8 thereof be at the top so that the top edges of the covers will bear against the same.

What I claim as new is:

1. A gauge for bookbinders comprising parallel gauge members having arms projecting at right angles from corresponding ends thereof in opposite directions and adapted to stand on edge, and means for adjustably connecting said gauge members whereby they may be moved to and from each other.

2. A gauge for bookbinders comprising parallel gauge members having arms projecting'at'right angles from corresponding ends thereof in opposite directions and the edges upon which said gauge mernbers and arms rest being chamfered and means for adjustably connecting said gauge members whereby they may be moved to and from each other. i

3.A gauge for bookbinders comprising ranei gauge members having arms pro- Jecting at right angles from corresponding ends thereof in opposite directions and adapted to stand on edge, and transverse rods and screws for adjustably connecting said gauge members to and from each other.

4. A gauge for bookbinders comprising parallel gauge members having tubular slit arms projecting at right angles from corresponding ends thereof in opposite directions and adapted to stand on edge, a transverse gauge-bar passing through said arms, and set-screws for clamping-"the slit portions thereof upon said bar.

51A gauge for bookbinders comprising parallel gauge members having tubular slit arms projectlng at right angles from corresponding ends thereof in opposite directions and adapted to stand on edge, a transverseau -b r P s h o d a ms, and set-screws for clamping" the slit portions thereof upon said bar, and a transverse rod one end of which is fastened in one gaugemember and extends through the other gauge member, and a set-screw that is tapped into the last referred to gauge-memher and said rod.

6. A gauge for bookbinders com rising parallel gauge members having tubuar slit arms projecting at right angles from correspending ends thereof in opposite directions,

the edges upon which the gauge members CHRISTIAN B. NELSON.
