HAT-BLOCK.

To all whom it 'may concern:

Be it known that I, VILLIAM 7. CUMBER- LAND, of the city of Newark, county of Essex, in the State of NewJersey, have invented a new and Improved Method of Fastening Blocks of food or Metal Together for Hatters7 Use and for other Purposes, and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention has for' its object fastening the several parts composing an entire block together in such a manner that they can be easily separated and be introduced singly` through an aperture smaller than the largest part of the block when all parts composing it are placed in their proper position and shall again become firmly attached to each ot-her when the parts are again brought into their proper relative position within the aperture and may be afterward readily withdrawn when required.

The accompanying drawings represent a block for pressing and finishing hats upon. This block fully illustrates my invention in every particular as the only change neces' sary to be made in the fastenings for blocks forother purposes will consist merely in a difference in their number or in the angle at which they are set with the face of the piece.

Figure l is a perspective view of the block when the parts are together. Fig. 2 is a plan. Fig. 8 is a Vertical section of the block when the pieces are together, through the points Z, m, Fig. 2. Fig. is a Vertical section through the same points as Fig. 3 when the center piece is being introduced the side pieces being drawn somewhat together as they would appear when first inserted into a hat. Fig. 5 is a side view of the fastenings detached from the block. Fig. 6, is a front view of the fastenings detached from the block. Fig. 7 is a section of the fastenings through the points w, 3/, in Fig. 5. Figs. 5 to 7 inclusive are drawn to a larger scale than Figs. 1 to 4; for the pur pose of showing the parts more plainly.

The same letters refer to the same parts in the different figures.

A is the center piece of the block.

B is the front piece of the block.

C is the back piece of the block.

D and E are the two side pieces of the block.

F is the spring catch.

G is the part of the fastening attached to the back of the center piece; H the part at tached to the front. I and J are similar fastenings attached to the two sides of the center piece.

G' is the partl of the fastening attached to the back piece O. H' is the part of the fastening attached to the front piece B. I' and J' are similar fastenings attached respectively to the two side pieces D and E.

The center piece A is of the form of a truncated rectangular pyramid having its base upward,

The fastenings Gr, H, I and J attached to the center' piece A are made of a tapering form in the direction of their length and also in 'the direction of their width and height eX cepting only the surface where they come in contact with and are attached to the faces of the center piece, these surfaces are made parallel with the outside surfaces vof the fastenings. The fastenings are attached firmly to the center piece by screws applied through holes in the parallel parts of the fastenings. In those fastenings to which a spring catch, (F) is secured the part of the surface around the screws is sunk below the general level of the outside so as to bring the screw heads below the general level of the outside of the fastening and leave a space for the spring catch F which is secured to the fastening by the lower' screw which passes through the lower end of it and through the fastening securing both of them to the block.

acute angle leaving a projection beyond the surface of the fastening at the bend which when the parts are together takes hold in a notch or recess in the piece opposite to it, and the spring after passing through a rectangular opening in the upper end of the fastening is again bent upward in the finger space of the center piece so that by placing a personls finger upon the end of the spring and pressing it toward the center of the block the catch is released from the notch and the center piece may be withdrawn.

lVlien attached to the center piece A the lower ends of the fastenings G, H, I and J project downward the inner surfaces of them being placed at an angle to the surface to which they are attached leaving a wedge formed space, the smaller part upward, between the inner surface of the fastenings' and the block as seen in Fig. 4: where the part projecting downward is marked K. In case the block is too short to allow the fastenings being attached at the end, the downward projections may be formed on the two sides of the fastening leaving a space for the screws between them the upward projections being also placedupon the sides leaving a corresponding space between them.

The front piece (B) of the block, the back piece (O), and the two side pieces (D and E) are inclined on their respective sides which are fitted to the center piece (A) at an equal angle to the central Vertical axis of the center piece as the corresponding sides of the center piece but in a reverse direction. The fastenings G', H', I', and J' are attached to them by screws as in the before mentioned fastenings, and are let into grooves formed in the face of the pieces B, C, D and E so that the outside surface of the fastening shall be a little below the surface of the piece. The grooves are formed of a corresponding cross section to the fastenings G, H, I, J attached to the center piece (A) and have a corresponding taper in their several directions, so that when the pieces are in their proper position they shall fit each other on the two sides, though it is not necessary 'that they should bottom.

The fastenings G' H' I' and J' have each an upward projection leaving a recess be- .faces of the downward and upward projections shall come in contact with and wedge against each other and wedge the pieces together firmly. The points of the downward projections are truncated somewhat and a correspondin ofiset left upon the opposite fastening an they are so placed upon their respective pieces that the point of one of the projections shall bottom so as to come in contact with the oflset on the other when the pieces of the block are in their proper relative position, so as to prevent them from being forced beyond the line of eachother in case a Cgreater pressure than usual should be applie to the center piece and thus prevent them from being wedged too tightly together so that they could not be readily withdrawn when required.

A slot is made in the point K of the fastenings G, H, I, and J which is shown in the drawings of one of them, namely G in Figs. 3 and 4, but is ntended to be applied to all the others. This slot opens downward and is narrowest near the upper end where it is made of the same width as the diameter of theA smooth neck of the extra screw which passes through the fastening G' into the bottom of the groove in the part C, and when the parts of the block are vtogether as seen in Fig. 3 this screw passes through the slot in the point K of the fastening also, and fits it on the two sides.` The design of this construction, is tol prevent the narrow sides of the point K of the fastening from pressing upon and wearing away the sides of the grooves in the block with which they come in contact and which, as the blocks are generally made of wood, would otherwise soonotake place from continued use, and in that case allow of a slight movement of the parts of the block upon one another.

Having thus described the several parts in their construction I proceed to show their manner of action when in use. The front and back pieces (B and C) and the two side pieces D and E are each separately inserted into the hat in their proper position with relation to each other and to the hat. The lower end of the center piece A, is then inserted between them and as it is pushed downward it gradually forces out the surrounding pieces, the fastenings upon the center piece A entering the grooves in the center, front, back and side pieces and the downward projections K upon the fastenings G, H, I, and J entering the recesses between the upward projections on the fastenings G', H', I', and J' and the bottom of the grooves until the inner surfaces of the downward and upward projections are brought into contact with each other smd by their shape and position wedge the parts firmly together, the sides of the fastenings G, H, I, and J being wedged against the sides of the grooves in the pieces B, C, D, and E and the points of the upward projections G', H', I', and J' coming in contact with the oifsets on the fastenings G, H, I, and J and the spring catch, F, falling into a recess or notch in the opposite piece B fitted to the projection of the spring catch which extends beyond the face of the fastening H and holds the center piece A from being withdrawn unless the upper part of the spring catch is pressed inward so as to withdraw the projection from the notch in the piece B.

What I claim as my invention and desire to secure by Letters Patent is:

In combination with the metal fastenngs attached to the sides of the ieces I claim preventing the points of the ownward projections (K) of the fastenings attached to the center piece from wearing away the sides of the grooves in the blocks (when formed of Wood) with which they come in contact,

by means of a slot inthe end of said projections and a screW passing through the corresponding part of the 'fastenings in the grooves and seoured in the Wood in the bottom of the grooves, the smooth neck of which shall enter the slot and fit it on the two sides When the parts are in proper position, substantially as described and for the pul'pose descrbed.
