HAT BLOCK Filed Nov. 12, 1951 3 Sheets-Sheet 3 E Inventor 7 gzfa/pado wu/as f1 ltorney Patented Apr. 18, 1933 UNITED STATES PATENT OFFICE GEORGEBEYS PAULOS PAPADOPOIILOS, DETROIT, MICHIGAN, ASSIGNOR OF SIXTY- SIX AND TWO-T'HIRDS PER GENT TO A. VICTOR BIZER, OF DETROIT, MICHIGAN HAT BLOCK Application filed November 12, 1931.

The present invention relates to new and useful improvements in hat blocks and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction, combination and arrangement of parts through the medium of which the device may be expanded or contracted simultaneously in four directions.

Other objects of the invention are to provide a hat block of the aforementioned character which will be simple in construction, strong, durable, elficient and reliable in operation and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention wiil become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a plan view showing a hat block constructed in accordance with the present invention with the sections in retracted position.

Figure 2 is a plan view of the hat block showing the sections extended.

Figure 3 is a detail View in cross section taken substantially on the line 33 of Figure 1 but with the sections extended.

Figure 4c is a sectional View taken sub-stantially on the line 14 of Figure 1.

Figure 5 is a detail view in perspective of one of the end sections.

Figure 6 is a detail view in perspective of one of the side sections.

Figure 7 is a detail View in elevation of the securing means for the meta'lic guides.

Referring to the drawings in detail, it will be seen that the hat block constituting the present invention comprises a substantially elliptical frame which is designated generally by the reference numeral 1, said frame including the curved duplicate end sections 2 and the curved side sections 3 which are also duplicate. The end and side sections are adapted for end abutting engagement with each other When said sections are in'retracted position.

Serial No. 574,629.

The end portions of the sections 2 are provided,'on their upper and lower sides, with the recesses 4 for slidably receiving the guides 5 which are formed integrally with the metallic plates 6 which are rigidly secured to the upper and lower sides of the sections 3 by securing elements comprising the headed, V threadedly connected male and female elements 7 and 8, respectively, which are illustrated in detail in Figure 7 of the drawings. '30

The guides 5 extend at an angle from the metallic plates 6 and are aligned with the end portions of the sections 2. The end portions of the sections 2 are provided with the sots 9 which terminate in spaced relation to the 5 ends of said sections 2, as best seen in Figure 5 of the drawings. Operable in the slots 9 are the pins 10 which extend between the pairs of guides 5. Sleeves 11 are rotatably mount- I ed on the pins 10 for travel in the slots 9.

Extending from the slots 9 to the ends of the sections 2 are the grooves 12 in the upper and lower sides of said sections 2.- The grooves 12 are aligned with the grooves 13 in the upper and lower sides of the sections 3.

here state that the metallic plates 6 are countersunk in the upper and lower sides of the sections 3, said sections 3 being recessed, as at 17 to accommodate the plates. The guide rods 15 extend adjacent the guide arms 5 and the metallic plates 6 provide means for securing said guide rods 15 in position.

The opposed faces of the side sections 3 are provided with sockets 18 for the reception of the outer end portions of the oppositely threaded screws 19 which are anchored in said side sections by the pins 20. A turnbuckle 21 in the form of a handle is operatively connected with the oppositely threaded screws 19 for simultaneously mov ing said screws outwardly or inwardly.

In use, when the side sections 3 are caused to move away from or toward each other by rotation of the turnbuckle 21, the end sections 2 are also caused to move simultaneously toward or away from each other through the medium of the pins and sleeves 10 and 11 which are carried on the guide arms 5 and which travel in the slots 9. The guide rods 15 prevent wobbling of the sections relative to each other and cause the ends of said sections to be brought squarely together when the sections are moved to fully retracted position.

It is believed that the many advantages of a hat block constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is 1. A hat block comprising a pair of side sections and a pair of end sections, said end sections having slots therein, means operatively connected with the side sections for shifting said side sections in opposite directions simultaneously, guide arms mounted on the side sections and extending slidably over the end sections, and pins mounted on the guide arms and extending through the slots for shifting the end sections in opposite directions relative to each other upon actuation of the side sections.

2. A hat block comprising a pair of side sections, means operatively connected with the side sections for shifting said side sections in opposite directions simultaneously, plates secured on opposite sides of the side sections, guide arms formed integral with the ends of the plates and extending therefrom at an angle, end sections mounted slidably between the guide arms, said-end sections having slots therein,and pins mounted on the guide arms and operable in the slots for shifting the end sections in opposite directions simultaneously upon actuation of the side sections.

8; A hat block comprising side sections and end sections adapted for end to end abutting engagement, said sections having aligned grooves in their adjacent end portions, guide rods anchored in certain of the grooves and engaged slidably in the other grooves, means operatively connected with certain of the sections for shifting said certain sections in opposite directions simultaneously, and means connecting the other sections with said certain sections for actuation thereby in opposite directions relative to each other.

4:. A hat block comprising side sections and end sections adapted for end to end abutting engagement, said sections having ably embracing said other sections therebetween, said other sections having slots therein, and pins extending between the pairs of guide arms and operable in the slots.

In testimony whereof I afiiX my signature.
