PHILIP 1:. e. ERICSON, or sr. CHARLES, ILLINOIS, Ass xenon To THE w. H. HQWELL doii- .PANY, or GENEVA, ILLINOIS, A coaro'aArIoN or ILLInoI's" PARASOL GONSTRUCT-TON Original application filed February 2, 1931, Serial No. 512,814. Divided and this application filedJ'uly 30,

This invention relates to parasols in general, particularly such as may be used with garden tables and the like, the principal object being to improve the mast head assembly from which radiate the several supporting ribs. The features of improvement herein disclosed and claimed have been divided out of my application filed February 2, 1981, Serial No. 512,814, patented Jan. 5,

An exemplification of this invention is illustrated in the accompanying drawings wherein- Figure 1 is a view in elevation of a parasol as used in connection With a garden table, a portion of a proximate side of the parasol being cut away to exhibit certain of the parts to the rear thereof; and

Fig. 2 is an enlarged vertical sectlon through the mast head assembly showing the connection therewith of the ribs which support the parasol.

The parasol herein illustrated is mounted upon a mast which may be supported in a vertical position as by a table. At its upper end which is socketed, the mast is provided with a tapered neck 3 extending upwardly from a plug at secured within the mast as by a pin 5. Fitted over and around this neck 3 is a head 6 having a base flange 7 with radial slots 8 within each of which is pivotally secured a rib 9 as at 10. V

A cap 11 of any suitable shape is placed over the head, its walls being configured to bear against the upper end of the latter. Formed centrally in the cap is an opening through which a screw 12 is threaded for connection within a socket formed in the neck. The cap serves a two-fold purpose,

$0 in that it extends beyond the head to provide a space wherein may be concealed and protected the turned edge of the parasol covering 14, and any associated fringe 15, and also bears against the top of the head so as to produce a tight frictional connection with the neck, in response to tightening of the screw, thereby preventing the head from turning relative to the mast.

The parasol is maintained in open condition as by means of the usual struts 16, one

being pivotally joined to each rib and to a common sleeve 17 which is slidable upon the mast between upper or lower limits. Detents of any approved kind (not shown) may be used to sustain the sleeve in the upper position indicated in Fig. 1.

The advantages of this construction reside in the simplicity of the several parts forming the mast head assembly. By the use of a single screw it is possible to firmly secure the parasol top to the mast in a manner which assures a non-rotatable connection therewith. In addition, the covering material, (also the fringe, if one be used) is secured in place and its edge is concealed by the cap which also furnishes protection to the pivotal joints. It is unnecessary that the diameters of the cap and head flange be the same, inasmuch as the thrust of the cap is resisted by the top of the head which acts to space the edges of the cap from the flange a suificient distance to avoid detrimental clamping upon the parasol covering and/or any fringe which is carried centrally thereof.

I claim:

1. In a parasol having a mast and ribs, the mast being socketed at its upper end, a plug secured within the socket and having a tapered neck portion extending upwardly beyond the mast, a head adapted to fit over and upon the neck and to engage therewith with a variable pressure, means for pivotally joining the ribs to the head, a cap fitted over the head, and adjusting means extending through the cap connecting with the neck adapted to secure and advance the head with increasing pressure against the neck.

2. A parasol having in combination a mast whose upper end terminates in a tapered neck, a head adapted to fit over and upon the neck and to engage therewith with a va riable pressure, a plurality of ribs each pivotally joined at one endto the head, a cap fitted over the head, and adjusting means engaging the head and connecting with the neck adapted to secure and advance the head with increasing pressure against the neck.

8. In a parasol having a mast, ribs and cover, the mast having a neck at its upper end, a head fitted around the neck and proice vided at its base with a flange to which the ribs are pivotally connected and upon which the cover is rested, a cap resting upon an upper portion of the head and maintained thereby in spaced relation to the flange below and in overlying non-engaging relation to the proximate portions of the parasol cover, and a single screw means for securing the cap upon the head and the head upon the mast neck.

PHILIP E. G. ERIOSON.
