SPECIFICATION forming part of Letters Patent No. 352,497, dated November 9, 1886.

Application filed January 1l, 1886. Serial No. 188,229.

To all whom it 11i/tty concern,.-

Be it known that we, GEORGE W. STREET, of Chicago, county of Cook, and State of Illinois, and JOHN S. VATTERS, of Baltimore, in the State of Maryland, have jointly invented certain new and useful Improvements in Bedclothing-Clamps for Beds and. we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved clamping device to be applied to a suitably-located framepiece upon a bedstead for the purpose of holding or securing in place the marginal parts of the bedclothing.

The invention consists in the mattershere- .inafter described, and pointed out in the appended claims.

The main features of the device herein shown as embodying our invention consist of a series of clamps, each comprising a stationary clamp-jaw attached to one ofthe framepieces of a woven-wire mattress, and a niovablejaw pivotally connected with the stationary jaw the several movable jaws being connected by a single rotating bar or rockshaft, whereby all of the jaws may be actuated at once in opening and closing them. Suitable means are provided, in connection with the shaft, for actuating the latterin opening and closing the jaws, as fully hereinafter set forth.

The invention may be more readily linderstood by reference to the accompanying drawings, in which-- Figure 1 is a side or exterior elevation of the frame of a woven-wire mattress provided with a series of clamps, and a rock-shaft for actuating the clamps, constructed in accordance with our invention. Fig. 2 is a transverse section of the same, taken upon line .fr x of Fig. l. Fig. 3 is a detail elevation of the ratchet-wheel upon the end of the roclrshaft for holding the jaws closed, shown in Fig. 1. Fig. 4 is a detail perspective view of one of the clamps shown in Fig. 1. Fig. 5 is a detail view of a clamp illustrating another means for holding the movable clamp-jaw in its closed position.

In the said drawings, A indicates the framepiece to which the clamping devices are at- (No model.)

tached, said frame-piece inthe particular construction illustrated being the end or footcrossbar of the frame of a wovenwire mattress.

B indicates, as a whole, the clamps, each of which consists ofa stationary j aw, B', attached to the frame-piece A, and a movable jaw, B2, which is pivotally connected withthe stationary jaw, said jaws being arranged with their free ends upward and in convenient position to engage the marginal parts of the bedclothtress, D, which rests upon the woven-wire fabric A', attached to the frame-piece A.

The clamp-jawsB B2 are preferably curved outwardly or spread apart from each other in which form the clamps proper, so'as to afford free or open spaces to receive the marginal part-s of the bedclothing which may be drawn downwardly into the clamps. The stationary jaw B' is preferably secured to the frame-piece A by means of a plate or flange, B3, thereon, extending beneath the frame-piece A, and is secured to the latter by screws, as shown, or otherwise. Said stationary jaw also is preferably cast with bearings B* for the roclrshaft E, which is arranged to pass through the bearings of the several clamps, and is rig- .idly connected with the movable jaws B2 of the latter to sustain and move the said several jaws.

As a simple and cheap construction in the shaft E, said shaft is, as herein shown, made throughout its entire length, and is fitted to b of the movable clamp-jaws B2, suitable cylindric bearingsurfaces being formed upon dric upon their outer surfaces and of proper size to enterthe bearings B4, and provided with square apertures, whereby they may be slipped over the rod. Said sleeves, as shown, are provided with set-screws e, to holdI them from endwise movement AYupon the rod; but they may be otherwise secured thereon in practice, as is found convenient or desirable.

One means applied to the rock-shaft E for actuating the clamp-jaws B2 and holding the latter closed is shown in Figs. l and 3. Inthese gures, F indicates a ratchet-wheel secorrespondingly-shaped apertures in the hubs ing C, herein shown as extended over a mattheir portions below their upper end portions y square in cross-section and of uniform size said shaft by means of sleeves E', made cylin- IOO cured upon the end ofthe shaft, and provided with a handle or lever, F', whereby said wheel and the shaft may be conveniently turned.

Upon the side rail, A2, of the .mattress-frame adjacent to the said wheel is pivoted a pawl, f, which is held in engagement with the wheel F by means of a spring, f, the teeth upon the wheel being so inclined as to allow the latter to be freely rotated in a direction to close the jaws. In the operation of this device the pawlf is released by hand from the ratchetwheel in opening the jaws, and the latter then turned by means of the handle F. until the clamp-jaws are opened sufticient to conven-` iently receive the marginal part of the bedclothing. In closing the jaws the ratchetwheel is turned in an opposite direction until the clothing is tightly clamped, when the pawl f, by its engagement with4 the ratchet-teeth, will prevent any backward movement of the movable clamp-jaws. Y.

In the particular construction illustrated in Fig. 1 the rockshaft E is shown as provided near its ends with additional bearings e,.se cured to the ends of the rails A2 A, the said shaft being provided with sleeves E', similar .to those before described, upon its part engaged with the said bearings e.

For the general purposes of our invention it is not necessary that the several movable clamp-j aws should be connected with and actuated by a singleshaft, although this construction is, for several reasons, a desirable one, and is herein specifically claimed as a preferred way of carrying out our invention. It is to be understood, furthermore, that the movable jaws may be held in position for clamping vthe clothing by other means than the ratchet-wheel and pawl shown.-as, for instance, the construction shown in Fig. 5 may be used, in

which a leaf-spring, G, is attached to the` movable jaw and adapted to press at its free end against the flange Bain such manner as to normally hold thejaws closed. In the use of a device constructed in this manner the several jaws may be secured to asingle shaft, so that all may be actuated together in the manner before described, in which case the shaft may have upon its end` a lever, as indicated at H, Fig. 5; orthe movable jaws may be in dependent of each other. When this latter construction is used, the jaws will be moved separately by the hand for the insertion of the bedclothing between them.

Aclampor a series of clamps such as above set forth may obviously beV appliedto a suitably-located stationary part or frame-piece of the bedstead proper, as well as to the frame- `piece of a woven-wire mattress, as herein illustrated. In some instances, also, the clamps will be attached to frame-pieces ofthe mattress, which also form the frame-pieces of the bed, as is the case, for instance, in a familiar form of cot or hospital-bed, in which suitableflegs' are attached directly to the frame of a wovenwith relation to the clamp when the latter is used upon a bedstead having a foot-board. The movable j aw Bz (shown in Fig. 2) is shaped at its outer part to permit the greatest possi'- ble movement in the upper end of saidjaw when a foot-board is present, the said jaw being adapted to swing outwardly until its end isbrought into contact with the foot-board, whereby the edges of the bedclothing may be readily inserted between the jaws preparatory to closing the clamps.

It is to be understood that the appended claims cover the several parts of devices therein set forth,when said several parts or devices are constructed in form to obtain either, any, or all of the advantages or benefits obtained by said parts or devices in the particular form thereof herein illustrated and above described.

Te claim as our inventiont 1. The combination, with a bed-frame, of a series of clamps comprising stationary and movable jaws, and a bar or rockshaft, E, engaging the several movable jaws for actuating the latter, substantially as described.

2. The combination, with a bed-frame, of a series of clamps comprising stationary and movable jaws, and a rockshaft supporting the said movable jaws, the stationary jaws being provided with bearings for the rock-shaft, substantially as described.

3. The combination, with a bed-frame and a series of stationary and movable jaws, of a rock-shaft, E, engaged with and supporting the said movable jaws, vand suitable bearings for the rock-shaft upon the frame, said rock- Shaft being ymade of square iron and provided with sleeves E', made cylindric upon their' holding said sleeves from end movement upon the shaft, and suitable bearings for the shaft engaging said sleeves, substantially as de scribed.

In testimony that we claim the foregoing as ourjoint invention we afix oursignatures in presence of two witnesses.
