A CORPORATION OF PENNSYLVANIA PORTABLE SIGN FRAME Application filed April 23,

Our invention relates to certain improvements in portable signs, of the type having a frame in which the sign can be placed and in which support for the sign can be of the rocking or non-rocking type as desired. The sign is particularly adapted to be used on the pavement to advertise the sale of certain commodities. This type of sign has to be made at low cost, yet must withstand the rough usage to which it is subjected.

One object of our invention is to make a very substantial sign of this type at low cost.

A further object of the invention is to pivot the feet of the sign to the mainframe,

so that one bolt of each foot can be removed and each foot turned upon the other bolt as a pivot, so as to uncover the slot in the lower portion of the frame for the insertion or removal of the sign. It will be understood that sign frames of this type will be so designed that difierent signs can be readily placed in the frame or removed therefrom.

A still further object of the invention is to so design the frame that the feet, when in position, will retain the sign within the frame.

These objects are attained in the following manner, reference being had to the accompanying drawings, in which:

Fig. 1 is a perspective view of our improved portable sign;

Fig. 2 is a perspective view showing the sign inverted and the feet turned on the pivots, so as to expose the slot in the bottom of the frame to allow for the insertion of the sum;

Fig. 3 is an inverted plan view of the sign with the feet in position;

Fig. 1 is an enlarged sectional view on the line 44:, Fig. 1, showing the heavy lower bars of the frame;

Fig. 5 is a view illustrating the feet reversed to form rockers, as in some instances these frames are designed so as to rock with the wind;

Fig. 6 is a sectional view on the line 6-6,

Fig. 1 of the side frame;

Fig. 7 is a detached perspective view of one of the corner brackets;

Figs. 8. 9 and 10 are sectional views of other forms of the side frame;

1930. Serial No. 446,721.

Figs. 11 to 16 are views illustrating modifications of the supporting legs;

Fig. 17 is a side elevation of a modified form of frame; and

Fig. 18 is a sectional plan view of one side of the frame shown in Fig. 17.

1 is a rectangular frame bent into shape. The two sides 22 and the top 3 are made in the form of channels as shown in Fig. 6, the flanges 4 of the channel members extending inwardly and spaced apart for the insertion of a sign a. The bottom member 5 of the frame is made of two heavy bars 5a, 5a, Fig. 4, which are spaced apart to allow for the insertion of the sign. The members of the frame are welded together in the present instance, although they may be otherwise secured. Vhile two solid bars rectangular in cross-section form the bottom member and which are of suflicient strength to give stiffness to the entire structure, the bars may in some instances be channel bars, and one may be heavy and the other may be comparatively light, without departing from the essential features of the invention.

Brackets 6 are secured to each lower corner of the frame, preferably by welding, and each bracket has a socket member 7 which fits around the edge of the side frames. Project ing from the socket member are wings 8.which are perforated at 9 for the passage of securing bolts 10 and 11. 12-12 are the legs which support the frame. These legs are of sulficient length to prevent the frame tipping and in the present instance are formed of channel shapes and are preferably curved as shown, so as to raise the bottom of the frame above the pavement or the floor. Each leg is secured to a bracket- 6 by two bolts 10 and 11, which pass through the holes 9 in the brackets. Vhen both bolts are in position, the frame is held rigidly on the legs. It will be noticed that the legs are of suflicient width and are so located that when they are in the position shown in Figs. 1 and 3, they extend under the edges of the slot between the bars of thelower member 5 of the frame, and act to retain the sign a in position in the frame.

When it is wished to renew or change the sign, the sign is inverted as shown in Fig. 100

2 and the bolts 11l1 on one side of the frame are removed, then the legs are turned on the bolts 10 as pivots to the position shown in Fig. \Vhen in this position the legs are at one side of the opening between the members 5a of the frame, so that the sign a can be readily removed from the frame and another sign placed in position, after which the legs are returned to the position shown in Fig. 3 and the two bolts 11 inserted, firmly securing the legs to the frame.

In some instances where the frame is to be used as a rocking frame, the legs 12 may be inverted as in Fig. 5, so that they become rockers which allow the frame to rock with the wind. The side members and top members :2 and 3 of the frame may be made in other shapes than that shown in Fig. 6.

Figs. 8, 9 and 10 are views showing different shapes which may be used for the side members and top member. While we prefer to use channel members bent as shown in Fig. 1 to form legs, the legs may be made from flat bars 1211 as shown in Figs. 11 and 12, the

= central portion of the legs being curved and the ends bent to form feet 13, or the legs may be formed of angle bars shown at 12b in Figs. 13 and 14 and bent and flared at each end to form feet 130, or the legs may be formed of angle bars 120 as shown in Figs. 15 and 16, the junction of the angles being at the center of the leg and the bar being straightened at each end to form feet 13?).

In the form shown in Figs. 17 and 18 the legs are secured to the frame by vertical bolts. each leg in this instance turning horizontally on one of the bolts to allow a sign to be removed from or inserted in the frame.

We claim 1. The combination in a portable sign of a. frame having side members and a top member in the form of channels, the flanges of the channels extending inwardly and spacedapart to form guides for a sign, the bot-tom member of the sign being made of two bars spaced apart for the passage of the sign; brackets secured to the lower end of the frame: and a leg at each side of the frame and secured to the brackets said legs closing the ends of the space between the two bars forming the bottom member of the sign, and

actinv to lock the sign in the frame.

2. &he combination in a frame, of side members and a top member shaped to form channels for a sign; bars spaced apart forming the lower member of the frame; brackets secured to each lower corner of the frame; two holes in each bracket spaced apart; two legs having holes therein corresponding to the holes in the bracket; and bolts securing the frame to the legs, one bolt on each side being-removable so that the legs can be turned on the other bolts as pivots to clear the channel in the lower member of the frame to allow for the withdrawal or replacement of a sign in the frame, the legs locking the sign in the frame when in normal position.

3. The combination in a portable sign, of a frame having channeled side members and a top member, the channels having inwardly pro ecting flanges spaced apart to form guides for a sign; a ottom member of the frame made of two bars spaced apart; brackets at each lower corner of the frame, said brackets having wings with bolt holes therein, the holes being located at a given distance beyond the sides of the sign; channeled legs having bolt holes therein; and bolts connecting the le s to the brackets so that one bolt on each si e can be removed to allow the legs to turn on the other bolts as pivots to expose the slot between the bars of the lower member of the frame, to allow for the insertion or withdrawal of the sign, the legs when in the normal position locking the sign in the frame.

4. A portable sign comprising a rectangular frame three sides of which are in the form of channel members having their channels inwardly disposed, the fourth side of which is in the form of spaced channel elements, between which asign may be inserted into the frame and its edges engaged by the channels of the first-mentioned sides; legs at each side of the frame; pivots for the legs arranged a at one side of the slot formed by the spaced channel elements: and means for securing the legs in position to support the frame and to retai n the sign withinthe frame, the legs when turned on their pivots being at one side of the frame so that the sign can be inserted or removed fromthe frame.
