Specification of Letters Patent.

Patented Aug. 28, 1906.

Application filed February 4, 1905. Serial No. 244,166.

To all whom, it may concern.-

Be it known that I, THoMAs A. BRIGGS, of East Greenwich, in the county of Kent and State of Rhode Island, have invented certain new and useful Improvements in Bookbindcry-Tables, of which the following is a specification.

This invention relates to tables for holding unbound books, magazines, pamphlets, &c., in convenient position for them to be con veyed to a stitching-machine, and has for its object to provide such a table which will be capable of holding work of a variety of characters.

The invention therefore consists of the table having the improvements which I will now proceed to describe and claimyreference bein had to the accompanying drawings, in whic 1 Figure 1 represents a table constructed according to my invention,- adapted to support work which is wide and flat. Fig. 2 repre sents the same table arranged to form a continuation of the saddle of a book-stitching machine to hold work of the pamphlet form which is stitched through the back. Fig. 3 represents the adjustment which adapts the table to support a quantity of work, such as unbound magazines, which are of comparatively small area and considerable thickness.

The same reference characters indicate the same parts in all the figures.

a represents the pedestal of a table in which is adjustably mounted a post I), capable of being raised and lowered relatively to the pedestal and held in any position of adjustment by a screw 0, which is engaged with the wings d of a split collar e, connected to the pedestal and surrounding the post I). The upper end of the post carries a vertical wing f, which cooperates with a complemental wing g, carried by the top h of the table, and these wings may be clamped together in any desired position by a clamping-screw-i. By adjusting the clamp the table-top may be set either horizontal, as shown in Fig; 1, or at any desired angle of inclination. If desired, the adjacent faces of the wings f and 9 may be provided with radial teeth or serrations or otherwise roughened in order to increase the hold of one upon another when they are clamped together.

Pivoted centrally to the edges of the tabletop h at its opposite ends are bracket-arms 7' 76, having perpendicular arms at their ends, to which arms is securely fastened a projecting member Z, extending perpendicular to the brackets. The bracket-arms j k are adapted to move about their pivots,carrying with them the member Z, to bring them into the plane of the table-top and are of such length that extreme position or the other, the member Z extends either upward from the supportingsurfaceof the table-top, forming an interior angle therewith, or downward from the opposite side of the top, forming an exterior or salient angle or ridge, and the top itself may be set at any angle. When in the first position, with the table-top horizontal, the member Z constitutes a stop or guard for retaining the sheets of paper to be stitched or other work which the table is designed to hold in an alined pile, while in the other position it is adapted to partially support the work. For convenience, however, and in order that a single distinctive term may be used to designate this member it will be hereinafter referred to as a stop.

When the parts are in the position shown in Fig. 1, the lower edge of the stop is beside the edge of the table-top and in the plane of the lower surface of the latter, while when the stop is turned into the position it occupies in F ig. 2 the same edge is in the plane of the upper surface of the table-top and the stop itself projects perpendicularly from the table-top in a generally downward direction. In Fig. 1 the table-top is placed in its horizontal position of adjustment and the stop is located so as to extend upwardly from one edge. The table is then in shape to hold a pile of wide sheets which are to be stitched together through from side to side at a line near the back edge to form thin volumes or pamphlets. The table will be placed close to the stitching-machine and its height properly adjusted to accommodate the attendant.

Fig. 2 shows the table-top adjusted on a slant of forty-five degrees with thestop projecting away from the upper surface of the top on an angle of forty-five degrees on the other side of the vertical, the table and stop together forming a work-support and presenting an angular saddle of the same shape as the saddle provided with stitching-machines for the purpose of stitching through folded sheets from the outside to the inside on the line of the fold. WVhen the table is in this condition, it is adapted to be placed in line with the saddle of the stitching-machine, so as to provide extra length therefor when acting on work of large size, such as certain large magazines which have four pages on eachsheet and are folded in the middle and stitched through the fold.

When in the position of adjustment shown ,in Fig. 3, the table can support large numbers of those magazines which are relatively thick and also of small lateral area. Within this form the stop serves as the support for the work, while the table-top it acts as an aliningstop. The latter will be tilted enough from the perpendicular to throw the guard outward and insure the work being retained. It

is evident that when in this position many more of the folded sheets which are used to make up the magazines can be heldthan is possible when the table is in the flat condition shown in Fig. 1.

The table above described is capable of being used for a variety of purposes and requires only slight manipulation and adjustment in order to fit it to perform any of the classes of work for which it is adapted. Such a table is a great convenience in a bindery, as it saves much time of the attendant of the -stitchingmachine and enables a machine to turn out a greater quantity of work for the same amount of attention on the part of the operative.

It will be seen from the drawings that the stop member Z is rectangular in form, of greater length than width, and that it has two parallel side edges, one of which normally lies adjacent to an edge of the table-top and in the plane thereof, while the other edge of the stop member is located at a distance from the table-top and is in a plane perpendicular to the top. Preferably the stop member is made from a piece of board, as is also the table-top, and in any event it has a continuous surface extending from side to side and from end to end without breaks or openings of any kind, and the side edges are also unbroken. This continuous and unbroken ex tent causes sheets of paper laid upon the top to be correctly alined and prevents a corner or other part of a sheet from projecting out, as would be the case if the stop member were discontinuous, while the parallel side edges of the stop member support the sheets when the table is used as a saddle and allow the sheets to be slid smoothly along the same.

I claim 1. A bindery-table comprising a work-supporting top adjustable angularly, a stop member cooperating therewith to hold work, and connecting means secured to said stop member and pivotally connected to the table on an axis adjacent the center line and in the plane of the table, the points of connection of said connecting means to the table,

and stop member respectively being separated by a distance substantially equal to half the width of the table.

2. A bindery-table comprising a top, a stop member, and rigid connections joining said member to the top with provision for movement from the edge at one side of the top to the edge at the opposite side thereof.

3. A bindery-table comprising a top having a supportingsurface, a stop member, and connections for holding said top and member together arranged to permit movement of the stop member while the supporting-surface of the top is uppermost from a position extending upward, to one extending downward from the supporting-surface adjacent a side thereof, said stop member having continuous side edges, one of which is normally beside and in the plane of the top, and the other separated therefrom and in a different plane.

4. A bindery-table comprising an adjustable top having a clear supporting-surface, a relatively movable stop member therefor and a support, the table-top and stop member having connections, the adjustment and connections being such that the top and member are angularly movable with respect to the support and to each other into positions with the top horizontal and the stop member projecting upright from one side edge thereof, the top inclined with its supporting-surface uppermost and the stop member extending at a downward inclination from an edge of such surface to form an angular saddle, and the top approximately vertical with the stop member extending laterally therefrom on a slight upward inclination.

5. A bindery-table comprising an adjustable top having a clear supporting-surface, a relatively movable stop member therefor and a support, the table-top and stop member having connections, the adjustment and connections being such that the top and member are angularly movable with respect to the support and to each other into positions with the top horizontal and the stop member projecting upright from one side edge thereof, the top inclined and the stop member projecting at a downward inclination from the opposite edge of the top to form an angular saddle, and the top approximately vertical with the stop member extending laterally therefrom on a slight upward inclination.

6. A bindery table comprising a top,

IIO

bracket members pivoted thereto and movable into the plane of the top on either side of the pivots, and a stop member connected to said bracket members, and arranged to move therewith into positions adjacent opposite side edges of the table-top.

. 7. A bindery table comprising a top, bracket members pivoted to opposite edges thereof and movable into the plane of the top on either side of the pivots, abutments mounted on the table-top and projecting beyond the edges thereof to limit the movement of said bracket members, and a stop member connected to said bracket members.

8. A table comprising a top, arms pivoted to opposite edges thereof midway of such edges and movable into the plane of the top on each side of the pivots, and a stop member connected to the arms and arranged to extend perpendicularly to the table-top when said arms are in the plane thereof.

9. A table comprising a top, arms pivoted to opposite edges thereof midway of such edges and movable into the plane of the top on each side of the pivots, the arms being of slightly greater length than the distance from the pivots to either intermediate side of the table, and a stop member connected to the ends of the arms and arranged in a plane perpendicular to that of the arms.

In testimony whereof I have afl'ixed my signature in presence of two witnesses.
