SPECIFICATION forming part of Letters Patent No. 435,191, dated August 26, 1890.

Application iiled November 16, 1889. Serial No. 330,570. (No model.)

To all whom it may concern.-

Be it known that I, J ULEs SARRAZIN, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in an Automatic Mosquito- Bar Frame; and I do declarev the following to be a full, clear, and exact description of the The objects of my improvements are to provide a device that will enable a mosquito-net to be drawn over the bed in a noiseless manner, and when the mosquito-net is loosened at the foot and side of the bed to be drawn back automatically. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a side elevational view. Fig. 2 is a perspective top view showing the metal frame with mosquito-net drawn.

Similarletters refer to si milar parts throughout both views.

In constructing my invent-ion I use an ordinary metal draw-bar, as shown by E, upon the ends of which I place an attachment, as shown by F, and within the opening in this attachment F, I insert the side bars D.

G are metal hooks which hold side bars D in position.

H are metal rings attached to the mosquitonet, and which rest on theside bars.

.I is a cord and tassel attached to draw-bar E for drawing the mosquito-net over the bed.

M is the canopy of the bed, to which pulleys L are attached.

K are cords attached to draw-bar E,'and which pass over pulleys L.

N are Weights or sand-bags attached to cords K, and which permit mosquito-net A to be drawn back when the front portion of the mosquito-nut, as shown by C, is released. The weights N do not exceed eight ounces each, and these are preferably made of sand in order to render the movement of the weights and mosquito-net noiseless. The attachments F, having rollers which are made of a plastic material, also prevent all noise as they travel back and forth over side bars D.

B shows the top of the mosquito-net.

The construction shown is an improvement upon my application filed on September 9, 1889, for devices for mosquito-bar frames, as I do not wish to claim the particular form and construction of the attachment F, as it is shown, described, and claimed in said former application.

The mode of operation is as follows: The mosquito'net by means of cord J, attached to draw-bar E, is drawn over the bed, as shown in Fig. l. The front portion of the mosquitonet, as designated by C, is pushed `under the mattress. This holds the mosquito-net in p0- sition when drawn over the bed. When it is desired to draw back the mosquito-net, it is released at the side of the bed and in front, and the weights N, descending, will draw back the net in a noiseless manner.

Having fully described my invention, what I claim, and desire to secure by Letters Patent,

The combination, with a bed-frame, of the horizontal frame M, secured to the head-board of the bed and supported on brackets, as shown, the horizontal side bars or rods supported in said frame by depending screw-eyes, and the pulleys L, depending from the rear under side of the frame, the sliding cross bar or rod E, having the attachments F on its opposite ends, and said attachments carrying rollers to travel on the side rods, the ropes K, connected at their forward ends to the transverse slide-bar and passing through the pnlleys and carrying weights N at their opposite ends, whereby the canopy may fold back automatically, and the cords J, also secured to the transverse slide-bar for retaining the canopyin an open position, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
