CLAMP.
Application led. February 1, 1923.
To @ZZ whom t may concern:
Be it known that l, FRANK Rnnsn, a citizen of the United States, residing at city of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Clamps, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to an improvement in clamps 'and particularly to clamps intended for use in combination with the ventilator windows of factory sash for securing screens thereto.
Factory sash is generally used to designate a large frame having a plurality of panes of glass fixed therein. Such sash has in most casesl one or more ventilator openings closed by hung orpivoted sashes. `When horizonally pivoted at the center it is obvious that the opening of the sash provides upper and lower openings and it is the purpose of this invention to provide means for securing screens in such openings.
Prior to this invention such screens have been secured to the factory sash by drilling holes in the framework and fastening the screen carrying clamps thereto. This method of attaching is objectionable not only because it permanently mars the framework but also because it is impossible to secure the clamps in place from the inside.
The chief object of this invention is to avoid the above objections by providing a clamp which can be quickly applied to the sash from the inside without marring the framework by the formation of screw holes.
Other objects reside in details of construction which will be set forth in the following specifications taken in connection with the drawing which forms a part thereof and in which- Figure 1 is a front elevation of a portion of a factory sash having a horizontally pivoted sash showing the screen applied to the upper opening by the use of clamps made in accordance with this invention.
Fig. 2 is a cross section through the line 2-*2 of Fig. 1 showing the lower mounting of the screen.
Fig. 3 is across section along the line 3 3 of F ig. 1 showing the mounting of ythe sides of the screen.
Serial N0. 616,447.
Figs. et and 5 show in plan and side elevation the blank from which the side clamps are formed.
Figs. 6 and 7 are similar views of the side clamp blank after the forming operation has been completed.
Figs. 8 and 9 are similar views of the completed side clamp.
Figs. 10 and 11 are plan and side elevations of the blank from which the bottom clamp is formed.
Figs. 12 and 13 are similar Views of that bank after the stamping operations have been completed.
Figs. 1a and 15 are plan and side elevations of a bottom clamp, similar to the bottom clamp shown in Fig 2 but differing therefrom in certain details of conformation.
Fig. 16 is a plan view of a blank from which the sheet metal strip, which forms one element of both types of clamps, is made.
Referring to the drawings, the reference numeral 20 is used to designate a factory sash having a plurality of fixed panes 21, 22, 23, 24, 25, 26, and 27 surrounding a sash 28 horizontally pivoted in the usual manner at yeach end of the muntin 29. In the particular type shown, the upper half of the sash swings inwardly and the lower half swings outwardly. The opening of the lowerY half is usually protected by the use of a stationary screen mounted on the inside of the vertical outlining bars and no further reference thereto will be made.
In order to screen the opening of the upper half it is necessary to allow for the swinging of the sash and one way to do so is to mount the lower portion of screen upon the muntin 29 of the sash so that the movement of the sash will not interfere with the screen, as shown for example in my Patent 1,343,933, dated June 22, 1920. For purposes of illustration, the clamps embodying this invention are shown applied to the screen 30 of this type which has at each sidev a longitudinal groove 31 into which project pins 32, carried by the side shields 33 which close the side spaces between the screen and the sash. The lower edge of the screen rests upon a horizontal strip 34 which is carried by the muntin 29, as shown particularly in Fig. 2. At the outer edge of the strip 34 is formed an annular bead 35 which rests Within a horizontal groove 36 of the screen corresponding to the ver,- tical groove 31. The bead 35 is removably held in the groove 36 by means of a plurality of screws 37 which project from the inner wall of said groove into slots 38 in the annular bead 35. By the provision of these slots it is, of course, obvious that the screen can oscillate vertically upon the strip 34. Y The horizontal strip is formed to rest upon the upper face of the muntin 29 and is provided with a plurality of slots 39 formed by striking vup portions 40 from the strip. The inner edge ofthe strip 34 is secured to the muntin 29 by clamps 41, embodying one form of this invention which pass through the slots 39, and engage theV muntin 29 above or below the strip.
Referring to Figs. 10, 11, 12 and 13 this clamp is preferably made from a flat blank 42 having a hole 43 adjacent one end and a 4slot 44 adjacent the other end. The relative position of the hole 43 and slot 44 is indicated in Fig. 10 by dotted lines. The hole 43 may be formed first and the slot 44 formed at the time the blank is bent at right angles, as shown .in Figs. 12V and 13 along a line between the slot and hole so that the portion bearing the hole 43 is at right angles to the portion bearing the slot 44. After the blank has been given the form shown on Figs. 12 and 13, a plate 45, formed as shown in Fig. 16, is applied by bending around the end of the clamp along the dotted linesindicated in Fig. 16. The plate may be first bent along the dotted line 46 providing a projecting portion 47 which is inserted into the slot 44 from the upper side, as illustrated in Fig. 3. The portion 47 is then bent along the line 43 against the under surface of the clamp and in order to prevent the plate working loose it is bent against the outer face of the clamp along the dotted line 49. ln order to lsecure the main portion of the plate to the clamp the sides 50 are bent downwardly and inwardly around the edges of the clamp. Finally the nose 51 is bent upwardly at an acute angle yto the clamp, along the dotted line 52, as
shown for example inrFigs. 9 and 15, to provide a hook for a purpose to be described later. Y
Referring particularly to Fig. 2 it will be noted that the muntin 29 has a triangularlike front portion 53 and a rectangular rear portion 54 projecting from the base 55 of the front portion 53. The panes of. glass 56 are embedded in putty 57 above and belowv the portion 54 and behind the base 55. Each clamp 41 is inserted through a slot 39 Ain the strip 34 andthe nose 51 is forced into the putty 57 behind the upper edge of the base 55 and in front ofthe pane 56. Since the portion of the clamp 41 bearing the hole 43 is at right angles to the slot-bearing portion, the former will lie on theY lower sideV of the triangular front portion 53 of the muntin 29. A screw 58 in the hole 43 is tightened against the under face 59 thus Yco-acting with the nose 51 andthe line of 'contact between the clamp 41 and the edge of the muntin to hold the clamp in place. rlhe slots 39 in the strip 34 are so located that when the clamps are tightened the strip is securely fixed to the muntin 29. ln order to increase the contacting surfaces of the strip 34 and the upper' vface of the. muntin, it is found advantageous togive the inner edge of the strip a contour similar to the muntin. Y
Figs. 14 and 15 disclose a third embodiment which may be used under certain conditions in place of the bottom clamps 41. It will be observed that these clamps 74 differ from the clamps 41 merely by aprovision of a rounded portion 75, as shown particularly in Fig. 15.
Throughout the specification and drawing the sas-h is set forth as composed of bars and muntins of a certain cross section. It isobvious that clamps made in accordance well to bars and muntins of different cross sections so that it will be understood that I am not restricted thereby.
IVhile certain embodiments have been shown and described, it is obvious that I am not limited thereto since other embodiments may be made without departing from the spirit and scope of this invention as set forth in the following claims.
Having thus set forth my invention, what I claim as new and for which I desire the protection of Letters Patent is:
l. A clamp, comprising two legs substantially at right angles to each other, having a transverse slot in one leg and a threaded hole in the other leg, a plate folded around the end of the first named leg and passing through the slot therein and a screw in the hole in the other leg, said plate and screw co-acting to hold said clamp in functioning position.
