Abstract

An umbrella tent construction includes a plurality of elongated resilient ribs each pivoted at one end to the flange portion of a top base member which includes a vertical post portion projecting downward from the flange. A brace is pivoted at one end to each rib intermediate the ends of the latter, and the opposite end of the braces are pivoted to a hub disposed vertically below the base member. The hub is movable vertically toward and away from the base member across a plane extending through the axes of the pivot connections of the braces to the ribs, to effect opening and closing of the ribs. Abutment means operatively interengages the base member and hub in a predetermined position of the latter above said plane, to limit the upward movement of the hub toward the base member and thus establish the open condition of the ribs. A flexible tent cover is secured to the ribs and is stretched tight as the ribs move toward said open position. The stretched cover resiliently resists vertical movement of the hub upward across said plane, whereby the hub snaps upwardly across said plane to said open position of the ribs in which the abutment means ingerengages the base and hub. The stretched cover thus locks the hub in said upward position and thereby secures the ribs in said open condition. By pulling the hub downward across said plane, against the resistance of the stretched cover, the hub and braces are unlocked, whereupon the braces and ribs are collapsed to tent-folding condition.

Kannan Attorney, Agent, or FirmOliver D. Olson [57] ABSTRACT An umbrella tent construction includes a plurality of elongated resilient ribs each pivoted at one end to the flange portion of a top base member which includes a vertical post portion projecting downward from the flange. A brace is pivoted at one end to each rib intermediate the ends of the latter, and the opposite end of the braces are pivoted to a hub disposed vertically below the base member. The hub is movable vertically toward and away from the base member across a plane extending through the axes of the pivot connections of the braces to the ribs, to effect opening and closing of the ribs. Abutment means operatively interengages the base member and hub in a predetermined position of the latter above said plane, to limit the upward movement of the hub toward the base member and thus establish the open condition of the ribs. A flexible tent cover is secured to the ribs and is stretched tight as the ribs move toward said open position. The stretched cover resiliently resists vertical movement of the hub upward across said plane, whereby the hub snaps upwardly across said plane to said open position of the ribs in which the abutment means ingerengages the base and hub. The stretched cover thus locks the hub in said upward position and thereby secures the ribs in said open condition. By pulling the hub downward across said plane, against the resistance of the stretched cover, the hub and braces are unlocked, whereupon the braces and ribs are collapsed to tent-folding condition.

[2 70' I0 /50 o z UMBRELLA TENT BACKGROUND OF THE INVENTION This invention relates to umbrella tents, and more particularly to a collapsible umbrella tent construction which is self-locking in the erected condition and which affords erection and collapsing in but a matter of a few seconds.

Collapsible umbrella tents provided heretofore utilize manually operable locking devices to secure the tent in erected condition. Such manually operable locking devices are unreliable, being capable of inadvertent release with consequence collapse of the tent. The operating parts of such locking devices also are susceptible of loss, breakage, or wear, thereby rendering the tent useless. Such manually operable locking devices also generally are located in positions not easily accessible for operation, thereby rendering the erection and collapse of the tent cumbersome and slow. Further, prior collapsible umbrella tents generally are characterized by a construction which includes a center post slidable through an apertured member at the top of the tent, thereby rendering difficult and costly the provision and maintenance of a liquid tight seal therebetween.

SUMMARY OF THE INVENTION In its basic concept, the umbrella tent of this invention utilizes the stretching of a flexible tent cover during erection of the tent to resiliently resist the over-center movement of a brace-supporting hub toward and away from a predetermined position relative to a top base member, to secure the tent releasably in erected condition.

It is by virtue of the foregoing basic concept that the principal objective of this invention is achieved; namely, to overcome the aforementioned disadvantages associated with umbrella tents of prior construction.

Another important object of this invention is to provide an umbrella tent construction which affords anchoring to the ground at an initial stage of erection, whereby to facilitate such erection under such adverse conditions as high winds.

A further object of this invention is to provide a collapsible umbrella tent construction which, in erected condition, is devoid of a long center rod projecting upwardly from the tent.

Still another object of this invention is the provision of a collapsible umbrella tent construction in which a screened opening in the tent cover may be sealed and exposed selectively by an external flap operable from within the tent.

The foregoing and other objects and advantages of this invention will appear from the following detailed description, taken in connection with the accompanying drawings of preferred embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENT The umbrella tent of this invention comprises a framework supporting a tent cover. The framework includes a top base member comprising a horizontal flange 10 and a vertical post 12 secured to the flange to form an integral, fixed unit. In the embodiment illustrated in FIG. 7, the flange is provided with a central threaded bore engageable removably by the intermediate threaded portion of the post, whereby to secure the flange and post together as an integral unit.

The flange is provided with a plurality of laterally extending pairs of lugs 14. The lugs of each pair are spaced apart and provided with axially aligned bores for the reception of a pivot pin 16. The space between the lugs of each pair freely receives the terminal end portion 18 of a connector component. Said terminal end portion is provided with a transverse bore arranged to align with the bores in the lugs to receive the pivot pin 16 therethrough. The connector component thus is secured pivotally to the flange.

The portion 20 of the connector component projecting outwardly from the pivoted portion 18 is provided with an outwardly extending groove in its top surface, for the reception of an end portion of an elongated resilient rib 22. In the embodiment illustrated, the rib is an elongated bar of rectangular cross section conforming to the cross sectional shape of the groove. The bar 3 is secured to the connector component by such means as the screws 24 illustrates.

In the embodiment illustrated, the tent framework includes four such ribs 22 disposed 90 from each other. Accordingly, the flange is provided with four pairs of laterally extending lugs 14 disposed at 90 intervals.

In this regard, it will be understood that a triangular tent may be provided by a flange having three pairs of lugs disposed at 120 intervals; a five sided tent may be provided by a flange having five pairs of lugs disposed at 72 intervals; and so on.

Intermediate the ends of each rib 22 there is secured a pivot bracket 26. As best illustrated in FIG. 11, this bracket is substantially C-shaped in cross section. The closed end of the bracket is provided with a longitudinal groove for the reception of the intermediate portion of the rib. The rib is secured to the bracket by such means as screws, in the manner of the screws previously described.

The spaced ends of the bracket receive freely between them the outer end portion 28 of a coupling component. Registering openings in the spaced end portions of the bracket and the coupling component receive a pivot pin 30 by which the coupling component is secured pivotally to the bracket.

The inner end portion 32 of the coupling component is reduced in diameter for the reception thereover, in a permanent press fit, one end of a tubular brace 34. The opposite end of the brace is provided with a similar coupling component, the outer end portion of which is secured pivotally, by means of a pivot pin 36 (FIGS. 7 and 8), between spaced lugs 38 of a hub 40. In the embodiment illustrated, the hub construction is substantially identical to the construction of the flange 10 described hereinbefore.

In order to provide a tent of substantial size when erected, but collapsible to minimum length for convenient transport and storage, each rib 22 preferably includes an elongated extension rib 42. The extension rib is secured at its upper end to the associated main rib by means of a pivot connector which limits pivotal movement of the extension rib through an arc of 180. Referring particularly to FIGS. 9 and 10 of the drawings, the pivot connector includes a substantially crossshaped body formed of a transverse section 44 and a pair of longitudinal sections 46 projecting in opposite directions from the transverse section. One coupling component is provided with a bifurcated end portion 48 freely receiving therein one of the longitudinal sections 46 and secured pivotally to the latter by a pivot pin 50. The outer end portion 52 of this coupling component is provided with a longitudinal groove for the reception of the lower end of the main rib 22 which is secured thereto by such means as the screws 54 illustrated.

A second coupling component is provided with a similarly bifurcated end 56 for the reception therein of the other of said longitudinal sections 46 of the body and for pivotal connection thereto by a pivot pin 58. The outer end portion of this coupling component is reduced in diameter for the press fit connection thereto of the upper end of the rib extension 42 which, in the embodiment illustrated, is in the form of an elongated tube.

As best illustrated in FIG. 10, the pivot connector functions to limit the arc of pivot of the rib extension 42 to substantially 180 relative to the main rib 22.

Thus, in the folded condition of the rib extension illustrated in broken lines, it is disposed closely adjacent and parallel to the main rib on the outer side of the latter. When the rib extension is pivoted counterclockwise from said folded position, the bifurcated end portion 48 of the coupling component is brought into abut ment with the transverse section 44 of the body, after substantially of pivotal movement, whereby the rib extension is in substantial alignment with the main rib.

The framework supports a tent covering 60 of flexible weather proof material. This material may be any conventional tent cover material such as canvas, but preferably is of light weight nylon or other synthetic thermoplastic material in fabric or sheet form, to minimize the weight and bulk of the assembly. It is shaped to the desired contour and dimensions of the erected tent, as will be understood.

In the preferred embodiment illustrated, a flexible floor covering 62 is secured to the bottom peripheral edge of the tent cover 60.

In the embodiment of FIGS. 16, the tent cover is secured over the framework by any suitable means. In the embodiment illustrated, and best shown in FIG. 6, flexible cloth loops 64 are secured to the inner side of the cover material at spaced intervals to confine the main and extension ribs therein. Other means, such as flexible cloth ties, etc., may be substituted for the loops, as desired.

Means also is provided for securing the bottom ends of the extension ribs 42 adjacent the corners of the tent cover to prevent their displacement. In the embodiment illustrated (FIG. 6) such means is provided by flexible socket elements 66 secured to the inner sides of the cover material. The socket elements may be made of canvas, leather, synthetic plastic, or any other material suitable for the purpose. Alternatively, flexible cloth ties may be substituted for the socket elements.

Means also is provided for anchoring the tent to the ground, when desired, to prevent its displacement. For this purpose a plurality of flexible anchor tabs 68 of canvas, leather, cloth, or other suitable material are secured to the outer side of the cover material 60 at the corners thereof and also preferably at the sides intermediate the corners. These tabs provide loops for the reception of anchor stakes or pegs adapted to be driven into the ground.

Means also is provided for securing the top of the cover 60 to the top base member. In the embodiment illustrated in FIG. 7, the top of the tent cover is provided with an opening 70, preferably defined by a thickened annular reinforcement 72. This opening is placed in registry with the threaded opening in the top base flange 10, prior to attachment of the post 12. The post then is extended downward through the registering openings and the threaded section thereof engaged with the flange. A projecting annular shoulder 74 on the post above the threaded section thus is brought downward into clamping engagement with the tent cover material which thus is clamped securely therebetween to form a water-tight seal.

In FIG. 14 the threaded opening through the flange 10 of the top base member is omitted and the vertical post 12 is secured to the underside thereof as by welding or other suitable means. The clamp shoulder 74 is formed on a separated short extension 12' of the post 12, and the extension is provided with a threaded shank 76 extending downward from the shoulder and through the opening 70 in the cover for threaded engagement in a threaded blind opening in the upper side of the flange portion 10. As in the embodiment illustrated in FIG. 7, the clamp shoulder 74 functions to clamp the adjacent cover material between it and the upper side of the flange portion, to provide a weather tight seal.

FIG. 15 illustrates alternative means by which the cover material is secured to the top base member. In this arrangement the center post 12 also does not extend upwardly through the flange 10, but additionally the cover is not provided with the top opening described hereinbefore. Instead, a plurality of flexible tie straps 78 are secured to the inner side of the cover material and are brought down to the underside of the flange 10, at the corners between adjacent pairs of lugs 14, looped about the post 12 and tied together. The cover thus is secured firmly to the flange. If desired, a flexible strap 80 may be secured to the outer side of the cover 60, across the flange 10, for engagement by the hand to assist in lifting the assembly, as described hereinafter.

The tent cover 60 is provided with an opening for passage to and from the tent, and a closure is provided for the opening. Although any conventional form of cosure may be provided for this purpose, the closure illustrated is in the form of a rectangular flap 82 (FIGS. 1-5). The flap is joined to the cover material along its upper edge, and removably closes the opening by such means as a slide fastener which extends along the sides and bottom of the flap and the corresponding sides and bottom of the cover opening. The flap may be made of the same material as the cover, or it may be of mosquito netting, or other suitable flexible material. In the embodiment illustrated, the flap is made of the same material as the cover, and an auxiliary mosquito meeting closure 84 also is provided. This netting is formed in two lateral sections secured along the side edges of the tent opening and provided at their adjacent, meeting edges with a slide fastener by which to secure the netting across the opening. When the slide fastener is open, the sections of netting material may be rolled to the lateral sides of the opening and there secured by such means as the flexible cloth ties 86 illustrated.

The flap 82 may be rolled upwardly to its top edge and secured by the flexible cloth ties 88 illustrated.

The tent cover 60 may also be provided with one or more screened windows 90 (FIG. 5). In such event means is provided for removably sealing the screened window against the elements of weather. In the preferred embodiment illustrated (FIGS. 16-18), such means is provided by a flexible weather-proof flap 92 which is capable of being manipulated between open and closed positions from the interior of the tent.

Thus, the flexible flap is secured at its upper edge to the outer side of the cover material 60 adjacent the upper edge of the window screen, as by means of stitching. The flap is wider and longer than the screen, whereby to completely cover the latter. The opposite side edges of the flap are provided with slide fasteners 94, snap fasteners, or other suitable means, by which to removably secure them to the tent cover. Thus, with the slide fasteners opened, the flap may be rolled upward to its upper edge and there secured by such means as the flexible cloth ties 96 illustrated.

Adjacent the lower end of the flap 90 is a centrally located buttonhole 98. This buttonhole is adapted to receive therethrough the enlarged head 100 at one end of an elongated peg 102. A flange 104 spaced slightly inward of the head confines the flap material surrounding the buttonhole between it and the head, whereby the peg is secured removably to the flap.

The opposite end of the peg is adapted to extend through an opening in the tent cover 60. In the embodiment illustrated, this opening is provided by a grommet 106 which is secured to the tent cover below the lower edge of the window screen. A shoulder 108 is provided on the peg adjacent the inner end of the latter to limit inward movement of the peg through the grommet opening. In the embodiment illustrated, this shoulder is provided by reducing the diameter of the inner end portion 1 10 of the peg. Alternatively, the shoulder may be provided by an annular flange on the peg, as will be understood.

Referring particularly to FIG. 18, the inner end portion 110 of the peg is provided with a transverse bore 112 and an intercepting longitudinal bore 114 which extends to the inner end of the peg. A flexible cord 116 is threaded inwardly through the longitudinal bore and thence outward through the transverse bore. A knot 118 then is formed in the end of the cord, to prevent the cord from being pulled outwardly through the longitudinal bore. The outer end of the cord is provided with a transverse pin 120 which is longer than the opening through the grommet 106 but whose diameter is smaller than the grommet opening. Thus, when the pin remains transverse to the cord, it cannot pass outwardly through the grommet opening. However, when the pin is disposed parallel to the cord, it may be passed outward through the grommet opening.

FIGS. 16 and 17 illustrate the flap 90 in opened position, allowing air to pass through the window screen into or out of the tent. In this opened condition, the inner end 110 of the peg 102 is anchored in the grommet 106 and the peg extends outward and slightly downward therefrom, holding the lower end of the flap outwardly from the tent cover. In this position, with the slide fasteners 94 closed, the peg is prevented from swinging upward, counterclockwise in FIG. 17, because the length of the peg from the flange 104 to the shoulder 108 is greater than the shortest distance between the buttonhole and the tent cover, on a line extending through the lower ends of the slide fasteners. Accordingly, the flap is secured in the opening condition against displacement by winds or other forces.

If it is desired to close the flap from the open condition illustrated in FIG. 17, a person within the tent need merely to push outwardly on the inner end of the peg 102 to disengage it from the grommet opening, whereupon the flap falls by gravity downward against the outer side of the tent cover.

To once again open the flap to the position illustrated in FIG. 17, a person within the tent merely grasps the inner end of the cord 116, which has been prevented from passing outward through the ground opening by virtue of the crossed pin 120, and pulls the cord inward through the grommet opening. The inner end portion 110 of the peg thus is guided into the grommet opening to the seated position illustrated in FIG. 17. During this movement the lower end of the flap is moved outward to the opened position.

If it is desired to completely expose the window screen 90, the inner end of the peg 102 is pushed outward from the grommet opening and the cord 116 and pin 120 also pushed outward through the grommet opening, by arranging the pin parallel to the cord so that both may be passed through the grommet opening.

The peg then is turned parallel to the lower edge of the flap 92 and the latter then rolled upwardly to its upper edge and there secured by the cloth ties 96.

It is an important feature of this invention that as the tent unfolds to fully open position, an over-center locking mechanism functions in association with the stretched tent cover 60 to secure the tent in said open position. In this regard, it is to be noted in FIGS. 1-5 that during erection of the tent the hub 40, to which the braces 34 are pivotally connected, moves upward toward the top base member. During its final upward movement the hub moves upward across a plane 122 (FIG. 6) which extends through the pivot pins 30 which anchor the outer ends of the braces to the main ribs 22. This over-center movement of the hub is resisted resiliently by the cover 60 which has become stretched across the ribs as the hub moved upward to said plane 122.

Thus, as the hub moves across said plane, the tension of the stretched cover impresses an inward force on the ribs and braces, tending to snap the hub further upward. Accordingly, means is provided for limiting the upward movement of the hub 40 toward the flange 10 of the top base member and hence to limit the inward contraction of the ribs to a degree that maintains the tent cover stretched.

Various types of abutment means may be interposed between the hub 40 and top base member to limit the upward movement of the hub beyond said plane 122. In the embodiment illustrated in FIGS. 6-8, the abutment is provided by a shoulder 124 formed between the reduced diameter lower section and main upper section of the vertical post portion 12 of the top base member. The hub thus is brought into abutment with the shoulder shortly after it has passed upward over said plane 122.

In the embodiment illustrated in FIG. 12, a tubular sleeve 126 is secured at its lower end to the hub 40 and extends upwardly therefrom. The upper end of the sleeve preferably is flared upwardly to guide its entrance over the post. Although the post may be long enough to extend through the hub, in the manner illustrated in FIG. 7, it may be sufficiently short, as illustrated in FIG. 12, to render it unnecessary to provide an opening through the hub. In such instance, the lower end of the sleeve may be secured to the upper surface of the hub, as by welding or other suitable means.

In the embodiment illustrated in FIG. 13, the post portion of the top base member is provided in the form of multiple telescoping sections 128, the lowermost section of which is secured to the hub 40. The shoulder 130 formed at the lower end of the uppermost section functions as an abutment for the hub, in manner similar to the shoulder 124 illustrated in FIG. 7.

It is to be noted, particularly from FIGS. 7, l2 and 13, that the post portion of the top base member is either a solid rod (FIGS. 7 and 12), or is otherwise closed at its upper end (FIG. 13). This construction is made possible by avoiding the necessity, as in some prior art constructions, of securing an elongated rod or cord at its lower end to the hub and extending it upward through an opening in the top base member. Thus, the present invention avoids the structural complication necessitated in such prior art constructions of providing a weather tight seal between such rod or cord and the top base member.

The operation of the collapsible umbrella tent described hereinbefore is as follows: First, let it be assumed that the tent is in its fully collapsed condition, i.e. the hub 40 is moved fully downward so that the main ribs 22 are pivoted inward on their pivot pins 16 and lie substantially parallel to each other closely adjacent the hub, and the extension ribs 42 are pivoted upward and lie closely adjacent the outer sides of the main ribs. From this fully collapsed condition, the first step of erection is illustrated in FIG. 1, wherein the extension ribs 42 are folded outward to rest upon the ground. This is accomplished by grasping the short outer extension of the vertical post portion 12 of the top base member in one hand to stabilize the vertical assembly, while the other hand swings the extension ribs outward.

Diametrically opposite main ribs 22 then are grasped one by each hand and pulled outward as far as possible (FIG. 2). By this means the bottom edge of the tent cover 60, and hence the floor 62 of the tent, are extended to their maximum dimensions. In the event the tent is being erected under such adverse conditions as a strong wind, the base of the tent may now be anchored to the ground, by stakes engaging the loops 68, as previously mentioned, while the main body of the tent is still in substantially collapsed condition and thus lease reactive to the wind.

In any event, the next step (FIG. 3), is to pull upward on the top base member, again by gripping the upward extension by the hand, until the hub 40 is elevated above the ground to a distance convenient to the operator.

The operator, who has been standing in the open door of the tent cover, then reaches into the tent with his free hand and pushes upward on the hub (FIG. 4) until the hub has snapped upward over the plane 122 (FIG. 6) and is brought to its fixed position of spacing relative to the top base member.

The foregoing sequence of manipulations illustrated in FIGS. 1-5 are capable of completion in the matter of about a few seconds. Equally rapid is the reverse sequence of collapsing the tent for transport or storage.

The tent is collapsed simply by pulling downward on the hub 40 with sufficient force to move it downward across said plane 122 (FIG. 6), whereupon the components of the tent assembly collapse substantially to a condition illustrated in FIG. 2. The extension ribs 42 then are folded upward against the outer side of the main ribs 22 and the latter collapsed fully toward the hub. The excess cover and floor material is then merely coiled about the collapsed framework and retained by encircling straps or cords, or by slipping the assembly into a carrying bag.

The tent construction described hereinbefore accommodates the provision of tents of diverse sizes and shapes. In the event the height of the tent is such as to render it difficult to grasp the short upper extension of the top base member, or the strap (FIG. 15) in the hand, during the final stages of erection (FIGS. 4 and 5), these final stages of erection may be accomplished by the operator solely by manipulation of the hub from within the tent.

In the embodiment of FIGS. l-6 the cover 60 is sup-.

9 which extends downward from a solid horizontal flange 10. I

A flexible strap 132 is secured intermediate its ends to the underside of the hub 40, as by means of a bolt 134 and interposed washer 136 (FIG. The terminal ends of the strap are secured to the outer side of the top center of the cover 60, as by means of stitching 138.

In similar manner, a pair of flexible straps 140 are secured to the opposite sides of each of the pivot brackets 26. In the embodiment illustrated, this is achieved by replacing the pivot pins of FIGS. 6 and 11 with pivot bolts 30 (FIG. 21) the head and nut of each being backed by washers, with the flexible straps interposed between the washers and the bracket 26. The inwardly extending ends of the straps are secured to the outer side of the cover 60, as by stitching 142.

Similarly, a pair of flexible straps 144 are secured to the opposite sides of each of the upper portions of the pivot connector for each rib section 22, as by replacing the pivot pin 50 of FIGS. 6 and 9 with a pivot bolt 50, similar to the pivot bolt 30 described hereinbefore. The inwardly extending ends of the straps are secured to the outer side of the cover 60 as by stitching.

If desired, a similar flexible strap 146 may interconnect the cover 60 and an intermediate portion of eadh of the rib sections 42.

The socket elements 66', similar to the socket elements 66 of FIG. 6 which anchor the bottom ends of rib sections 42, are connected to the bottom edge of the cover 60 by means of flexible straps 148, as will be apparent.

The foregoing arrangement of flexible straps allows the frame to be collapsed in the manner described hereinbefore and to be extended to the erected condition illustrated in FIG. 19, following the same procedures described hereinbefore in connection with FIGS. l-5. In the erected condition of FIG. 19, the stretched cover 60 resists movement of the hub 40 across the plane 122, in the same manner as described hereinbefore.

If desired, a shielding flap 150 of flexible, waterproof material may be provided to overlie the upper portion of the tent framework and cover 60. As illustrated in FIG. 19, the flap is contoured to the external shape of the erected framework and is provided with a central opening 70' for reception of the threaded shank 76 on a separate short extension 12' which includes a clamp shoulder 74, in the manner illustrated in FIG. 14. The central portion of the flap thus is secured in position against the flange 10 of the top base member. The flap also may be secured to each of the rib sections 22. In the embodiment illustrated (FIG. 21), this is achieved by providing openings 152 in the flap material registering with threaded openings provided in the rib sections 22, preferably adjacent the bracket 26 and coupling component carrying pivot bolt 50', for reception of anchor bolts 154. In this manner, the shielding flap is rendered removable, but may be retained in position substantially permanently.

The provision of the shielding flap 150 of waterproof material allows the main cover 60 to be made of very thin fabric which need only be water repellent while allowing air to pass through it. The space between the cover 60 and flap 150 allows circulation of air which reduces materially the temperature and humidity within the tent.

From the foregoing, it will be appreciated that the present invention providesan umbrella tent which may be collapsed to minimum bulk for eacy transport and convenient storage, and which may be erected with speed and facility to provide an enclosure of substantial size, free of internal obstructions. As described hereinbefore, when the tent construction includes the extension ribs 42, the base of the tent may be expanded to full dimensions for anchoring to the ground, while the tent remains in substantially collapsed condition. This materially assists in erection and collapse of the tent under such adverse conditions as high winds. The simplified construction contributes significantly to minimum cost of manufacture and long service life with minimum maintenance and repair.

It will be apparent to those skilled in the art that various changes may be made in the size, shape, number, type and arrangement of parts described hereinbefore without departing from the spirit of this invention.
