Specification of Letters Patent.

Patented Oct. 5 1915.

Application filed February 21, 1914. Serial No. 8:20,?512.

To all whom it may concern: I

Be it known that I, HARVEY C. Snnnnn, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Furniture Anchors, of which the following isa specification.

My invention relates to furniture anchors and arms particularly to provide a type of device that may be used in connection with school desks or similar furniture used in assembly halls in general, and also in connection with gymnasium appliances. It is frequently necessary i to remove this furniture for various purposes and this re.- moval has always been a source of a great amount of trouble. a

My invention aims to provide an attachment which may be permanently placed in the floor, of the hall, being embedded therein in a manner that its upper surface will be flush with the surface of the floor. An attaching structure of peculiar form is then caused to engage the furniture and, by a slight rotation, this attaching structure so engages the member embedded in the floor in a manner to securely hold the furniture in position; I also aim to provide a type of bolt for use in connection with the member placed in the floor, which is such that the bolt itself may never pass entirely through the floor member. Further, this floor member and the attaching bolt are preferably so constructed that the bolt is positively limited in its rotation, to lockitself in position.

structure shown by me in the accompany ing sheet of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure 1 is aview in perspective of a portion of a well known type of school desk shown held in position by the use of my invention, Fig. 2 is an enlarged side elevation of my furniture anchor showing a portion of the structure in section, Fig. 3 is a bottom View of the socket member used by me, Fig. 4- is a section taken on line 44 of Fig. 2 and looking in the direction of the arrows, Fig. 5 is a section taken on line 55 of Fig. 3, and Fig. 6 is a side elevation of the socket member used by me.

In illustrating my invention, I have any type of furniture Wherever convenient.

In Figs. 2, 3, 5 and 6, I have shown a socket member which forms one of the essential features of my invention, this socket 7 member comprising a body portion 5, being externally threaded as is shown at 6. EX-

tending centrally through this socket member is an elongated slot 7 communicating at its lower end with a counterbored portion 8 of substantially circular formation, although I have provided this counterbored portion with inwardly projecting shoulders 9, these shoulders 9 having one side disposed substantially at right angles to the long dimensionof the slot 7, as is shown at 10. Go-

operating with this socket member is a bolt 11 having a flattened and drawn-out head, as shown at 13, this head being shaped somewhat similar to the slot 7 and being adapted to be inserted therethrough to rest in the lower countersunk portion, as is more clearly shown in Fig. 2. Determinately spaced above the level of this head, I have provided two fins 14, these fins being set at such angle with respect to the head 13, that they will prevent passage of the entire bolt through the slotted portion, after the head 13 has been passed through this portion and given a slightturn to prevent its removal, it being understood that the head 13 cooperates with the flat sides 10 of the inwardly projecting shoulders 9 tolimit the amount this bolt is turned. The upper end of the bolt is threaded as at 15, for the reception of a nut 16, which nut is adapted to hold a clamp 17 in firm engaging position with the furniture. This clamp 17 is provided with an overhanging tongue such as is shown at 18 and also with a right angular upwardly extending arm 19 at its lower end. This arm being of a width equal to the width of the bracket itself, Willprevent its easy rotation when the anchors are located in their correct position, it being understood that a number of these anchors are used for each piece of furniture.

' fins 1% engage the upper edge'of this slot,

socket member in position, the threads on the exterior of this socket member serving as a means for retaining it in its position.

after its top is level With the top surface of the floor. 'The bolt 11 is then dropped into position by permitting the head 13 to pass through the'slotted portion 7 and When the because of their peculiar angular position, the bolt itself is given a bodily quarterly turn, which will bring the head 13 out of registration With the slot 7 and prevent removal of the bolt by an upward pull, be cause of the engagement of this head With the bottom Wall of the counterbored portion 8. Further, the shoulders 9 prevent an eX- cessive rotation of the bolt and thus insure a correct pos1t1on.- The fins 14 not only serve the purpose of lndicatlng When'the bolt head has reached the countersunk portion 8, but also prevent dropping of the bolt entirely through this socket member. After the bolt is in position, the bracket 17 is placed in'gripping engagement and the nut.

16 screwed home, thus firmly anchoring the furniture in position. e

What I claim, is 1. A furniture anchor comprising a socket member having an elongated slot passing Qopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

through its body, a bracket member adapted to engage the furniture, a bolt and nut for engaging said bracket member and said socket member, said bolt being provided With ahead similar in shape to the slot in said body member said socket member being arranged to engage the head of the bolt When the bolt is given a partial turn and fins on said bolt disposed at such an angle with respect to its head to limit its through said socket member.

2. Afurniture anchor comprising a socket member having an elongated slot passing through its body, the bottom of said member, having a substantially circular countersunk portion communicating with said elongated slot, inwardly projecting shoulders in said countersunk portion, a boltand nut, a

passage.

flattened head on said bolt. adapted to fit b said, slot and engage the shoulders in said countersunk portion When the bolt is given a partial turn, fins on said bolt disposed at such an angle ith respect to its 'headto limit its passage through the socket mem-. her, and a bracket member for engaging the furniture and held on said bolt by saidnut. In testimony whereof I afiix my signature in presence of two Witnesses. v
