DISAPPEARING BED.

Specification of Letters Patent.

Patented June 16, 1914.

Application tiled April 22, 1914. Serial No. 833,580.

To UZ whom it may concern:

Be it. known that I, ALDEN D. BLAKE, a citizen of the United States of America, re' Iiding at. Detroit, in the county of lVaync and State of Michigan, have invented certain new und useful Improvements in Disappearing Beds, of which the following is a specification, reference being had therein to the accompanying drawings.

'.lhe invention relates to folding beds of that type in which the bed frame is connected to a carrier, by means of which it may in collapsed position be swung into a closet or other place of concealment.

It is the object of the resent invention to obtain a construct-ion otp carrying or transporting means by which the collapsed bedstcad may be quickly and easily removed to its point of concealment, and further to obtain a construction which permits of readily attaching or detaching the bed from the carrier.

To this end the invention comprises the construction as hereinafter set forth.

In the drawings: Figure 1 is a side elevation showing the bed frame in extended position; Fig. 2 is a plan view showing the carrier collapsed and the folded bed in position of concealment, also indicatin in dotted lines the intermediate position o transportation; Fig. 3 isa detail illustrating the construction of the carrier and the manner oi detachably envaging the same with the bod frame; and Figa 4 is an enlarged detail view.

A is a collapsible or foldable bed of any suitable construction, not shown in detail; is the head-board or foot-board of the bed; and C is the carrier or transporting device, bv means of which the folded bed 1s transferred to the place of concealment. This carrier C is constructed of a series of parallclogram levers or what is sometimes termed a lazy-tong, the arrangement being such as to permit of a longitudinal extension or contraction while affording support for the load. The inner end of the carrier C is attached to a suitable anchorage such as a vertical rod D secured to the wall E by brackets F. To this anchorage the cross connected end levers G and G are secured so as to be capable of a pivoting action, and one of the levers, such as the lever G is also permitted a vertical sliding movement on the-rod D. In detail H is a sleeve slidably secured upon the rod D, having an outward1yproject1ng ear H which is pivotally attached to the lever G', and H2 is a similar sleeve having the ear H3 pivotally attached to the lever G. The outer end of the carrier C is detachably secured to the head or foot-board B, preferably by mounting upon the latter a vertical rod I having sleeves J and J engaging the same. One of the sleeves, such as the upper sleeve J, forms a bearing for supporting the load, while the other sleeve slidably enga es the rod I. Both sleeves have a detacha le swivel engagement with the carrier C, preferably by providing them with biurcated ears J2, having a knuckle e O'a ement with ears K on the pivot-al fittings for the end levers G2 and G3. Thus the ears K may be engaged between the bifurcated ears J 2 and secured by a pivot pin L.

With the construction as described in use, when the lazy-tong carrier C is extended, as shown in Fig. 1, the ears K of the outer levers Gr2 and Gs are in position for engagement with the bifurcated ears J 2 of the sleeves J and J', t-he bed being inextended the ed may be collapsed or folded, and by then moving it forward the lazy-tong carrier will be shortened so as to transport the bed into the place of concealment. During this movement the weight of the bed is supported by the carrier While the swivel connection between the ears K and bifurcated ears J2, as well as the swivel connection of the sleeves H u on the rod D, will permit the turning of tiie collapsed bed to pass through a narrow doorway. The placing of the load upon the carrier may be ei't'ectet either upon the collapsing or folding of the bed, or if desired the lazy-tong carrier may be so arranged that as it is contracted in length the outer end will be slightly7 raised. The latter would be the case with the construction as shown in Fig. 1, in which the load of the bed is directly carried through the upper sleeve J or the lever G2, while at the opposite end of the carrier the load is transmitted through the lower sleeve H2 to the bracket F for the anchor rod D. This permits the u per sleeve H at the inner end of the carrier and the lower sleeve J at the outer end of the carrier to travel upon their respective rods, the result being that as the carrier is extended its outer end is lowered, while the cortraction of the carrier will raise the outer en To permit the movement of the sleeves or opened-out position. When thus engaged,V

upon the rods D and I without the necessity of lubrication, roller bearings M are preferablv secured thereto for engagement with Toassist in the movement of the transporting carrier, I preferably provide a tensioning device, such as the spring N which at one end is suitably anchored, as at IO, and at the opposite end is-atta-Ched to the' carrier, asf at P., By means of this spring detach thetransportin carrier therefrom'- The operation of detac ent is facilitated by the'provision of means for relieving the tension of the spring N during detachment. is shown, I have provided a' yoke or spanner Q, which may be engaged with' the opy of the spring posite'pivotal connections of the-lazy-tong lever to revent a lateral movement thereof. This o e is so proportioned as, to-be engagea le with'the carrier in the extended position thereof and while yet attached to the bed, and by reason of the fact that it prevents the levers from expanding laterally, longitudinalmovement in collapsed po-.

sition "is also prevented. Thus the tension l\ will be relieved and the ears of the fittings K may be readily detached from the bifurcated ears J2 of the fitting J.-

After the carrier is 4detached from the bed the yoke may be removed to permit of collapsing and storing the carrier, and whenever 1t is desirable to re-attach the. carrier to the bed it may be again extended and engaged with the yoke so as to hold the fittings in-position of 'registration for attachnient to the bed. In specific construction the yoke Q is provided with pins Q which engage apertures in the pivotal connection of opposite ends of the lazy-tong levers, as shown in Fig. 3.-

What I claim as my invention is z- 1. The combination with a collapsible bed,

of 'a transporting carrier therefor comprising a longitudinally',contractible and extensiblesupporting arm, an anchor connection for one end of said arm, and means for supporting th'e bed at the opposite end of said arm.

2. The' combination withacollapsible bed, of-a. transporting carrier therefor comprising a longitudinally extensible and contractible supporting arm, an anchor support to which the inner end of said arm is pivotally attachedand a ivotal connection between the bed and t e outer end of said noechefe a lazy-tong extensible arm, an anchoring connection for the inner end of said arm and to which it is pivotally attached, and a si'vivel supporting connection between the' outer end of said arm and said bed. 6i The combination with a collapsible bed,A

of a transporting carrier therefor comprising a. lazy-tong extensible supporting arm, an anchor connection for the inner'end of said arm, and a detachable connection lbetween the outer end of said arm-and said bed.

6., The combination with a collapsible bed, of a transporting carrier therefor comprising a lazy-tong extensible 'supporting arm, anv anchor connecti'on for the inner end of said, arm, a connection between the outer end of said arm and 'said bed, and means for supporting the'load of said collapsible bed upon said arm during the collapsing movement.

7. Thecombination with a collapsible bed, of a transporting carrier therefor, comprising a lazy-tong extensible supporting arm, an anchor connection for the inner end of said arm, a connection between the outer end of said arm and the bed, and resilient means for assisting in transporting the bed upon said carrier.

8. The combination with a collapsible bed, of a transporting carrier therefor, comprising a lazy-tong extensible supporting arm, an anchor connection for the--inner end of said arm, a detachableconnection between the outer end of said arm and the bed, a

tension device for collapsing said arm and' posite pivotal connection of the lazy-tong, to hold the same from movement during at' tachment'to or detachment from the bed.

In testimony whereof I affix my signature in presence of two witnesses..
