CONNECTION FOR BEDSTEADS AND THE LIKE,
Application filed February 2011924.
' T all whom it may concern:
Be it known that 1, MICHAEL citizen of the United States, and-a resident of West New York, in the county of End son and State of New Jersey, have invented certain new and useful Improvements in Connections for Bedsteads and whichv the following is a specification.
This invention relates to that class of connections shown in-iny prior application filed August 41, 1923, and the objects of the present improvements are to secure such a connection in which the wedgingly movable member shall normally be in position for the end of the rail to be inserted for engagement with respect to the post; tothus avoid any necessity for lifting J. PINKLO, a
the movable member to permit insertion ofthe rail end, and leave both hands free for other purposes; to utilize for themovable member a dog or cam pivoted to normally swing into position to admit the rail-end and adapted to beturned by engagement of the rail-end into looking to provide the lower end of the cam, which is first engaged by the rail-end to turn the cam, with means for causing less friction there than at the point where the rail-end engages the cam for locking purposes, and to*obtain other advantages and resultsns may be brought out bythe following description.
Referring to the accompanying drawing, in which the same numerals of reference designate corresponding and like parts,
Figure 1 is a vertical sectional view of a portion of a bed post and side rail, taken on line 1-1 of Fig. 2, a portion of the depending flange of the side rail being shown entire; 1
Figure 2 is a plan of the same with a certain lug in section;
Figure 3 is a transverse section on line 3-3 of Fig. 2;
Figure 41 is a vertical section taken cen trally of the post, connection andend otthe rail, showing a modified form of cam, and Figure is a transverse section of the same on line 55 of Fig. 4.
Inthe specific embodiment-of the invention shown in Figures 1-3inclusive, 1 indithe like, of
engagement therewith Serial No. 693,976.
cates one of the posts of either the headboard or foot-board of a metal bedstead, and 2 indicates one or the side rails. The post 1 is sho'wnsquare and hollow and the rail2 is shown of angle iron, althoughboth or-either oi 'these parts might'be of other common and well-known form. To the out side of the post 1 is suitably secured, as'by' spot welding at 3, 3, a bracket 4 which is in' general channel-shaped with a connecting portion or back 5 lying against the post 1 and wings 6, 6 projecting therefrom. One of the wings is shown with a lateral projecting lug 7 to which maybe bolted a bar extending to a similar lugon the similar bracket of the opposite post of the headboard or foot-board, said her not being shown as it is common and well-known con struction.
Between the wings 6, 6 of the bracket 4 is pivoted a. cam 8, as by means of a pin 9 extending through the wingsti, 6, and having outside one of them a head 10 and outside the other a cotter pin 11, or any other well-known means' for preventing escape of the pin. The cam 8 is shown reduced at its opposite ends to form hub portions 12, 12 and its middle portion projects at the opposite side of the pin 11 from the post 1, as at 18, sufliciently'to normally overbalance the cam 8 and throw its inner lower projecting portion 14 against the back 5 of the bracket. Above this lower projecting portion 14 is a curved portion '15 which wedg ingly engages the rail end, when inserted, to jam it toward the post.
The side rail 2 is shown provided with an md piece 16, the stem 17 of which is shown made fast to the side rail as by means-oi rivets 18, 18 extending through one of the flanges o'lthe angle iron side piece. The outer end of the end'piece is provided with a right angular arm 19, said arm being of such a thickness that it will jam "between the back 5 of the bracket and the curved portion of the cam 8 as the lattertnrns on its pins 9, due to pressing the end post of the rail downward. By hooking the arm 19 overthe cam 8 when it is in normal po sition, the extremity oi the cam first engages the lower inner projection 1d ofthecam to disconnection is readily effected by lifting the end of the side rail 2 upward out of the seat between the cam and back 5 of the bracket.
The end piece 16 of the side rail'2is preferably provided with a second lateral arm 20, opposite the arm 19, and forming therewith a T-head, so that the side rail can be reversed or turned upside down, as is useful in adapting a bedstead with angle iron side rails to be used either with or without slats.
In Fi ures 4L and 5 I have shown a movablewe ging member 21 mounted between the wings 22 of a bracket 23, which member 21, is made hollow so that it can be stamped from heavy sheet metal or similarly made. lhe closed top 24 is uppermost and the opposite parallel legs'25, 25 depend and receive throughthemselves the pin 26. Preferably washers 27, 27 are placed upon the pin at opposite sides of the pivoted member 21 to space it from the wings 22, 22. The outer end 28 of the member or cam 21 is heavy enough to normally hold it in position to receive the end piece 29, as
.already described in connection with Fig ures 1-3, the eccentrically curved inner edges 30 of the legs 25, 25 engaging said end piece to wedge it in place. The lower ends of the legs 25, 25 are also adapted to be engaged at their inner edges by the end piece to tilt the cam into engagement with the end piece, and in order to ensure less friction at this part of the cam than at its eccentrically curved edges 30 I prefer to employ a friction roller 31 at the lower part of the cam mounted upon a pin 32 extending from one leg to the other.
Other modifications in the construction of my invention may be made by those skilled in the art, and'the connection can be em loyed for posts and rails of any kind to which it is applicable, whether forming part'of a bedstead or not; therefore, I do not wish to be understood as limiting myself except as required by the following claims when construed in the light of the prior art. 1
Having thus described the invention, what I claim is,-
1. The combination with a post having a bracket and a transverse member on said bracket movable wedgmgly toward the post,
of an end piece on a rail or the like having a lateral arm to extend between said post and member and be jammed by the latter toward the post upon downward movement, said member normally being held out of jamming position and adapted to be engaged by the lateral arm of the rail and moved into said position.
2. The combination of a bracket adapted to be applied to a post and providing spaced projecting wings, a cam pivoted between said wings at a distance from the post, and an end piece adapted to be applied to a rail or the like having a depen ing arm to of the cam next the post and upon downward movement turn said cam to jam said arm toward the post.
3. The combination with a post having a bracket, and a cam on said bracket facing said post, of an end piece on a rail or the like having a lateral arm to extend between said post and cam and be jammed by the latter toward the post upon downward movement, said cam normally being held out of jamming position and adapted to be engaged by the lateral arm of the rail and moved into said position.
4. The combination with a post having a bracket, and a cam on said bracket facing said post, of an end piece on a rail or the like having a lateral arm to extend between said post and cam and be jammed by the latter toward the postupon downward movement, said cam being weighted to normally swing away from said post and having an extension adapted to be enga d by the lateral arm of the rail to swing t e cam into engaging position.
5. The combination with a post having a bracket, and acam on said bracket having at its; side facing said post an upper engaging portion and a lower contact portion, said cam being weighted to normally hold said upper engaging portion away from the post and said. lower contact portion toward the post, of an end piece on a rail or the like having a lateral arm adapted to extend between said post and cam and engage the lower contact portion to throw the upper engaging portion against said arm.
6. The combination with a post having a bracket, and a cam on said bracket having at its side facing said post an upper engaging portion and a lower contact portion, said cam being weighted to normally hold said up er engaging portion away from the post an said lower contact portion toward the post, of an end piece on a rail or the like having a lateral arm adapted to extend between said post and cam and engage the lower contact portion to throw the upper engaging portion against said arm, and means for causing said lower contact portion to engage said arm With less upper ei'igaging portion away from the post friction than the upper engaging portion. and said roller toward the post, of an end 7. The combination With a post having piece on a rail or the like having a lateral 10 a bracket, and a cam on said bracket havarm adapted to extend between said post 5 ing at its side facing said post an upper and cam and engage the roller to throw the engaging portion and a lower roller, said upper engaging portion against the arm. cam being Weighted to normally hold said MICHAEL J. PINKLO.
